Oracle Application Express APIs

This section describes the APIs available in Oracle Application Express.


Note:

In release 2.2, Oracle Application Express APIs were renamed using the prefix APEX_. Note that API's using the previous prefix HTMLDB_ are still supported to provide backward compatibility. As a best practice, however, use the new API names for new applications unless you plan to run them in an earlier version of Oracle Application Express.

Topics:

APEX_MAIL

You can use the APEX_MAIL package to send an email from an Oracle Application Express application. This package is built on top of the Oracle supplied UTL_SMTP package. Because of this dependence, the UTL_SMTP package must be installed and functioning in order to use APEX_MAIL.


See Also:

Oracle Database PL/SQL Packages and Types Reference for more information about the UTL_SMTP package

APEX_MAIL contains three procedures. Use APEX_MAIL.SEND to send an outbound email message from your application. Use APEX_MAIL.PUSH_QUEUE to deliver mail messages stored in APEX_MAIL_QUEUE. Use APEX_MAIL.ADD_ATTACHMENT to send an outbound email message from your application as an attachment.


Note:

The most efficient approach to sending email is to create a background job (using a DBMS_JOB package) to periodically send all mail messages stored in the active mail queue.


SEND Procedure

This procedure sends an outbound email message from an application. Although you can use this procedure to pass in either a VARCHAR2 or a CLOB to p_body and p_body_html, the data types must be the same. In other words, you cannot pass a CLOB to P_BODY and a VARCHAR2 to p_body_html.

When using APEX_MAIL.SEND, remember the following:

Syntax

APEX_MAIL.SEND(
    p_to                        IN    VARCHAR2,
    p_from                      IN    VARCHAR2,
    p_body                      IN  [ VARCHAR2 | CLOB ],
    p_body_html                 IN  [ VARCHAR2 | CLOB ] DEFAULT,
    p_subj                      IN    VARCHAR2 DEFAULT)
    p_cc                        IN    VARCHAR2 DEFAULT)
    p_bcc                       IN    VARCHAR2 DEFAULT);
    p_replyto                   IN    VARCHAR2 DEFAULT);
RETURN NUMBER;

Parameters

Table: SEND Parameters describes the parameters available in the SEND procedure.

SEND Parameters

Parameter Description

p_to

Valid email address to which the email will be sent (required). For multiple email addresses, use a comma-separated list

p_from

Email address from which the email will be sent (required). This email address must be a valid address. Otherwise, the message will not be sent

p_body

Body of the email in plain text, not HTML (required). If a value is passed to p_body_html, then this is the only text the recipient sees. If a value is not passed to p_body_html, then this text only displays for email clients that do not support HTML or have HTML disabled. A carriage return or line feed (CRLF) must be included every 1000 characters.

p_body_html

Body of the email in HTML format. This must be a full HTML document including the <html> and <body> tags. A single line cannot exceed 1000 characters without a carriage return or line feed (CRLF)

p_subj

Subject of the email

p_cc

Valid email addresses to which the email is copied. For multiple email addresses, use a comma-separated list

p_bcc

Valid email addresses to which the email is blind copied. For multiple email addresses, use a comma-separated list

p_replyto

Address of the Reply-To mail header. You can use this parameter as follows:

  • If you omit the p_replyto parameter, the Reply-To mail header is set to the value specified in the p_from parameter

  • If you include the p_replyto parameter, but provide a NULL value, the Reply-To mail header is set to NULL. This results in the suppression of automatic email replies

  • If you include p_replyto parameter, but provide a non-null value (for example, a valid email address), you will send these messages, but the automatic replies will go to the value specified (for example, the email address)


Examples

The following example demonstrates how to use APEX_MAIL.SEND to send a plain text email message from an application.

-- Example One: Plain Text only message
DECLARE
    l_body      CLOB;
BEGIN
    l_body := 'Thank you for your interest in the APEX_MAIL 
package.'||utl_tcp.crlf||utl_tcp.crlf;
    l_body := l_body ||'  Sincerely,'||utl_tcp.crlf;
    l_body := l_body ||'  The APEX Dev Team'||utl_tcp.crlf;
    apex_mail.send(
        p_to       => 'some_user@somewhere.com',   -- change to your email address
        p_from     => 'some_sender@somewhere.com', -- change to a real senders email address
        p_body     => l_body,
        p_subj     => 'APEX_MAIL Package - Plain Text message');

ADD_ATTACHMENT Procedure

This procedure sends an outbound email message from an application as an attachment. To to add multiple attachments to a single email, APEX_MAIL.ADD_ATTACHMENT can be called repeatedly for a single email message.

Syntax

APEX_MAIL.ADD_ATTACHMENT(
    p_mail_id                   IN    NUMBER,
    p_attachment                IN    BLOB,
    p_filename                  IN    VARCHAR2,
    p_mime_type                 IN    VARCHAR2);

Parameters

Table: ADD_ATTACHMENT Parameters describes the parameters available in the ADD_ATTACHMENT procedure.

ADD_ATTACHMENT Parameters

Parameter Description

p_mail_id

The numeric ID associated with the email. This is the numeric identifier returned from the call to APEX_MAIL.SEND to compose the e-mail body.

p_attachment

A BLOB variable containing the binary content to be attached to the e-mail message.

p_filename

The filename associated with the e-mail attachment.

p_mime_type

A valid MIME type (or Internet media type) to associate with the e-mail attachment.


Examples


PUSH_QUEUE Procedure

Oracle Application Express stores unsent email messages in a table named APEX_MAIL_QUEUE. You can manually deliver mail messages stored in this queue to the specified SMTP gateway by invoking the APEX_MAIL.PUSH_QUEUE procedure.

Oracle Application Express logs successfully submitted message in the table APEX_MAIL_LOG with the timestamp reflecting your server's local time. Keep in mind, the most efficient approach to sending email is to create a background job (using a DBMS_JOB package) to periodically send all mail messages stored in the active mail queue.

Syntax

APEX_MAIL.PUSH_QUEUE(
    p_smtp_hostname             IN    VARCHAR2 DEFAULT,
    p_smtp_portno               IN    NUMBER   DEFAULT;

Parameters

Table: PUSH_QUEUE Parameters describes the parameters available in the PUSH_QUEUE procedure.

PUSH_QUEUE Parameters

Parameters Description

p_smtp_hostname

SMTP gateway host name

p_smtp_portno

SMTP gateway port number


Note that these parameter values are provided for backward compatibility, but their respective values are ignored. The SMTP gateway hostname and SMTP gateway port number are exclusively derived from values entered on the Manage Environment Settings when sending e-mail.

Example

The following example demonstrates the use of the APEX_MAIL.PUSH_QUEUE procedure using a shell script. This example only applies to UNIX/LINUX installations.

SQLPLUS / <<EOF
APEX_MAIL.PUSH_QUEUE;
DISCONNECT
EXIT
EOF

APEX_MAIL_ATTACHMENTS View

You can use the APEX_MAIL_ATTACHMENTS view in conjunction with the existing APEX_MAIL_QUEUE to access email attachments associated with email messages in the Oracle Application Express mail queue.

Example

The following example demonstrates how to access files stored in APEX_APPLICATION_FILES and add to an e-mail message.

DECLARE
    l_id number;
BEGIN
   l_id := apex_mail.send( p_to        => 'fred@flintstone.com',
                           p_from      => 'barney@rubble.com',
                           p_subj      => 'APEX_MAIL with attachment',
                           p_body      => 'Please review the attachment.',
                           p_body_html => '<b>Please</b> review the attachment' );

    FOR c1 IN (SELECT filename, blob_content, mime_type
                 FROM apex_application_files
                WHERE ID IN (123,456)) LOOP
        --
        apex_mail.add_attachment( p_mail_id => l_id,
                               p_attachment => c1.blob_content,
                                 p_filename => c1.filename,
                                p_mime_type => c1.mime_type);
  END LOOP;
  COMMIT;
END;

APEX_ITEM

You can use the APEX_ITEM package to create form elements dynamically based on a SQL query instead of creating individual items page by page.


CHECKBOX Function

This function creates check boxes.

Syntax

APEX_ITEM.CHECKBOX(
    p_idx                       IN    NUMBER,
    p_value                     IN    VARCHAR2 DEFAULT,
    p_attributes                IN    VARCHAR2 DEFAULT,
    p_checked_values            IN    VARCHAR2 DEFAULT,
    p_checked_values_delimiter  IN    VARCHAR2 DEFAULT)
    RETURN VARCHAR2;

Parameters

Table: CHECKBOX Parameters describes the parameters available in the CHECKBOX function.

CHECKBOX Parameters

Parameter Description

p_idx

Number that determines which APEX_APPLICATION global variable will be used. Valid range of values is 1 to 50. For example 1 creates F01 and 2 creates F02

p_value

Value of a check box, hidden field, or input form item

p_attributes

Controls HTML tag attributes (such as disabled)

p_checked_values

Values to be checked by default

p_checked_values_delimiter

Delimits the values in the previous parameter, p_checked_values


Examples of Default Check Box Behavior

The following example demonstrates how to create a selected check box for each employee in the emp table.

SELECT APEX_ITEM.CHECKBOX(1,empno,'CHECKED') " ",
       ename,
       job
FROM   emp
ORDER BY 1

The following example demonstrates how to have all check boxes for employees display without being selected.

SELECT APEX_ITEM.CHECKBOX(1,empno) " ",
       ename,
       job
FROM   emp
ORDER BY 1

The following example demonstrates how to select the check boxes for employees who work in department 10.

SELECT APEX_ITEM.CHECKBOX(1,empno,DECODE(deptno,10,'CHECKED',NULL)) " ",
       ename,
       job
FROM   emp
ORDER BY 1

The next example demonstrates how to select the check boxes for employees who work in department 10 or department 20.

SELECT APEX_ITEM.CHECKBOX(1,deptno,NULL,'10:20',':') " ",
       ename,
       job
FROM   emp
ORDER BY 1

Creating an On-Submit Process

If you are using check boxes in your application, you might need to create an On Submit process to perform a specific type of action on the selected rows. For example, you could have a Delete button that utilizes the following logic:

SELECT APEX_ITEM.CHECKBOX(1,empno) " ",
       ename,
       job
FROM   emp
ORDER  by 1

Consider the following sample on-submit process:

FOR I in 1..APEX_APPLICATION.G_F01.COUNT LOOP
    DELETE FROM emp WHERE empno = to_number(APEX_APPLICATION.G_F01(i));
END LOOP;

DATE_POPUP Function

Use this function with forms that include date fields. The DATE_POPUP function dynamically generates a date field that has a popup calendar button.

Syntax

APEX_ITEM.DATE_POPUP(
    p_idx          IN    NUMBER,
    p_row          IN    NUMBER,
    p_value        IN    VARCHAR2 DEFAULT,
    p_date_format  IN    DATE DEFAULT,
    p_size         IN    NUMBER DEFAULT,
    p_maxlength    IN    NUMBER DEFAULT,
    p_attributes   IN    VARCHAR2 DEFAULT)
    RETURN VARCHAR2;

Parameters

Table: DATE_POPUP Parameters describes the parameters available in the DATE_POPUP function.

DATE_POPUP Parameters

Parameter Description

p_idx

Number that determines which APEX_APPLICATION global variable will be used.Valid range of values is 1 to 50. For example, 1 creates F01 and 2 creates F02

See Also:

Oracle Database SQL Language Reference for information about the TO_CHAR or TO_DATE functions

Example

The following example demonstrates how to use APEX_ITEM.DATE_POPUP to create popup calendar buttons for the hiredate column.

SELECT 
  empno, 
  APEX_ITEM.HIDDEN(1,empno)||
  APEX_ITEM.TEXT(2,ename) ename, 
  APEX_ITEM.TEXT(3,job) job, 
  mgr, 
  APEX_ITEM.DATE_POPUP(4,rownum,hiredate,'dd-mon-yyyy') hd,
  APEX_ITEM.TEXT(5,sal) sal, 
  APEX_ITEM.TEXT(6,comm) comm,
  deptno
FROM emp
ORDER BY 1

DISPLAY_AND_SAVE Function

Use this function to display an item as text, but save its value to session state.

Syntax

APEX_ITEM.DISPLAY_AND_SAVE(
    p_idx         IN    NUMBER,
    p_value       IN    VARCHAR2 DEFAULT NULL,
    p_item_id     IN    VARCHAR2 DEFAULT NULL,
    p_item_label  IN    VARCHAR2 DEFAULT NULL)
    RETURN VARCHAR2;

Parameters

Table: DISPLAY_AND_SAVE Parameters describes the parameters available in the DISPLAY_AND_SAVE function.

DISPLAY_AND_SAVE Parameters

Parameter Description

p_idx

Number that determines which APEX_APPLICATION global variable will be used.Valid range of values is 1 to 50. For example, 1 creates F01 and 2 creates F02

p_value

Current value

p_item_id

HTML attribute ID for the <input> tag

p_item_label

Label of the text field item


Example

The following example demonstrates how to use the APEX_ITEM.DISPLAY_AND_SAVE function.

SELECT APEX_ITEM.DISPLAY_AND_SAVE(10,empno) c FROM emp

HIDDEN Function

This function dynamically generates hidden form items.

Syntax

APEX_ITEM.HIDDEN(
    p_idx     IN    NUMBER,
    p_value   IN    VARCHAR2 DEFAULT)
    RETURN VARCHAR2;

Parameters

Table: HIDDEN Parameters describes the parameters available in the HIDDEN function.

HIDDEN Parameters

Parameter Description

p_idx

Number to identify the item you want to generate. The number will determine which G_FXX global is populated

See Also: "APEX_APPLICATION"

p_value

Value of the hidden input form item


Example

Typically, the primary key of a table is stored as a hidden column and used for subsequent update processing, for example:

SELECT
  empno, 
  APEX_ITEM.HIDDEN(1,empno)||
  APEX_ITEM.TEXT(2,ename) ename,
  APEX_ITEM.TEXT(3,job) job, 
  mgr, 
  APEX_ITEM.DATE_POPUP(4,rownum,hiredate,'dd-mon-yyyy') hiredate,
  APEX_ITEM.TEXT(5,sal) sal, 
  APEX_ITEM.TEXT(6,comm) comm, 
  deptno
FROM emp
ORDER BY 1

The previous query could use the following page process to process the results:

BEGIN 
  FOR i IN 1..APEX_APPLICATION.G_F01.COUNT LOOP
    UPDATE emp
    SET
      ename=APEX_APPLICATION.G_F02(i),
      job=APEX_APPLICATION.G_F03(i),
      hiredate=to_date(APEX_APPLICATION.G_F04(i),'dd-mon-yyyy'),
      sal=APEX_APPLICATION.G_F05(i),
      comm=APEX_APPLICATION.G_F06(i)
    WHERE empno=to_number(APEX_APPLICATION.G_F01(i));
  END LOOP;
END;

Note that the G_F01 column (which corresponds to the hidden EMPNO) is used as the key to update each row.


MD5_CHECKSUM Function

This function passes values to APEX_ITEM.MULTI_ROW_UPDATE and is used for lost update detection. Lost update detection ensures data integrity in applications where data can be accessed concurrently.

Syntax

APEX_ITEM.MD5_CHECKSUM(
    p_value01   IN    VARCHAR2 DEFAULT,
    p_value02   IN    VARCHAR2 DEFAULT,
    p_value03   IN    VARCHAR2 DEFAULT,
    ...
    p_value50   IN    VARCHAR2 DEFAULT,
    p_col_sep   IN    VARCHAR2 DEFAULT)
    RETURN VARCHAR2;

Parameters

Table: MD5_CHECKSUM Parameters describes the parameters available in the MD5_CHECKSUM function.

MD5_CHECKSUM Parameters

Parameter Description

p_value01

...

p_value50

Fifty available inputs. If no parameters are supplied, the default to NULL

p_col_sep

String used to separate p_value inputs. Defaults to the pipe symbol (|)


Example

SELECT APEX_ITEM.MD5_CHECKSUM(ename,job,sal)
FROM emp

MD5_HIDDEN Function

This function is used for lost update detection. Lost update detection ensures data integrity in applications where data can be accessed concurrently.

This function produces a hidden form field and includes 50 inputs. APEX_ITEM.MD5_HIDDEN also produces an MD5 checksum using the Oracle database DBMS_OBFUSCATION_TOOLKIT:

UTL_RAW.CAST_TO_RAW(DBMS_OBFUSCATION_TOOLKIT.MD5())

An MD5 checksum provides data integrity through hashing and sequencing to ensure that data is not altered or stolen as it is transmitted over a network

Syntax

APEX_ITEM.MD5_HIDDEN(
    p_idx       IN    NUMBER,
    p_value01   IN    VARCHAR2 DEFAULT,
    p_value02   IN    VARCHAR2 DEFAULT,
    p_value03   IN    VARCHAR2 DEFAULT,
    ...
    p_value50   IN    VARCHAR2 DEFAULT,
    p_col_sep   IN    VARCHAR2 DEFAULT)
    RETURN VARCHAR2;

Parameters

Table: MD5_HIDDEN Parameters describes the parameters available in the MD5_HIDDEN function.

MD5_HIDDEN Parameters

Parameter Description

p_idx

Indicates the form element to be generated. For example, 1 equals F01 and 2 equals F02. Typically the p_idx parameter is constant for a given column

p_value01

...

p_value50

Fifty available inputs. Parameters not supplied default to NULL

p_col_sep

String used to separate p_value inputs. Defaults to the pipe symbol (|)


Example

The p_idx parameter specifies the FXX form element to be generated. In the following example, 7 generates F07. Also note that an HTML hidden form element will be generated.

SELECT APEX_ITEM.MD5_HIDDEN(7,ename,job,sal), ename, job, sal FROM emp

MULTI_ROW_UPDATE Procedure

Use this procedure within a Multi Row Update process type. This procedure takes a string containing a multiple row update definition in the following format:

OWNER:TABLE:pk_column1,pk_idx:pk_column2,pk_idx2|col,idx:col,idx...  

Syntax

APEX_ITEM.MULTI_ROW_UPDATE(
    p_mru_string    IN    VARCHAR2 DEFAULT)
    RETURN VARCHAR2;

Example

To use this procedure indirectly within an application-level process, you need to create a query to generate a form of database data. The following example demonstrates how to create a multiple row update on the emp table.

SELECT 
empno,
APEX_ITEM.HIDDEN(1,empno),
APEX_ITEM.HIDDEN(2,deptno),
APEX_ITEM.TEXT(3,ename),
APEX_ITEM.SELECT_LIST_FROM_QUERY(4,job,'SELECT DISTINCT job FROM emp'),
APEX_ITEM.TEXT(5,sal),
APEX_ITEM.TEXT(7,comm),
APEX_ITEM.MD5_CHECKSUM(ename,job,sal,comm),
deptno
FROM emp
WHERE deptno = 20

Note the call to APEX_ITEM.MD5_CHECKSUM, instead of APEX_ITEM.MD5_HIDDEN. Since APEX_ITEM.MULTI_ROW_UPDATE gets the checksum from APEX_APPLICATION.G_FCS, you need to call APEX_ITEM.MD5_CHECKSUM in order to populate APEX_APPLICATION.G_FCS when the page is submitted. Additionally, the columns in APEX_ITEM.MD5_CHECKSUM must be in the same order those in the MULTI_ROW_UPDATE process. These updates can then processed (or applied to the database) using an after submit page process of Multi Row Update in a string similar to the following:

SCOTT:emp:empno,1:deptno,2|ename,3:job,4:sal,5:comm,7:,:,:,:,

POPUP_FROM_LOV Function

This function generates an HTML popup select list from an application list of values (LOV). Similar from other available functions in the APEX_ITEM package, POPUP_FROM_LOV function is designed to generate forms with F01 to F50 form array elements.

Syntax

APEX_ITEM.POPUP_FROM_LOV(

    p_idx              IN    NUMBER,
    p_value            IN    VARCHAR2 DEFAULT,
    p_lov_name         IN    VARCHAR2,
    p_width            IN    VARCHAR2 DEFAULT,
    p_max_length       IN    VARCHAR2 DEFAULT,
    p_form_index       IN    VARCHAR2 DEFAULT,
    p_escape_html      IN    VARCHAR2 DEFAULT,
    p_max_elements     IN    VARCHAR2 DEFAULT,
    p_attributes       IN    VARCHAR2 DEFAULT,
    p_ok_to_query      IN    VARCHAR2 DEFAULT,
    p_item_id          IN    VARCHAR2 DEFAULT NULL,
    p_item_label       IN    VARCHAR2 DEFAULT NULL)
    RETURN VARCHAR2;

Parameters

Table: POPUP_FROM_LOV Parameters describes the some parameters in the POPUP_FROM_LOV function.

POPUP_FROM_LOV Parameters

Parameter Description

p_idx

Form element name. For example, 1 equals F01 and 2 equals F02. Typically, p_idx is a constant for a given column

p_value

Form element current value. This value should be one of the values in the p_lov_name parameter

p_lov_name

Named LOV used for this popup

p_width

Width of the text box

p_max_length

Maximum number of characters that can be entered in the text box

p_form_index

HTML form on the page in which an item is contained. Defaults to 0 and rarely used.

Only use this parameter when it is necessary to embed a custom form in your page template (such as a search field that posts to a different Web site). If this form comes before the #FORM_OPEN# substitution string, then its index is zero and the form opened automatically by Oracle Application Express must be referenced as form 1. This functionality supports the JavaScript used in the popup LOV that passes a value back to a form element.

p_escape_html

Replacements for special characters that require an escaped equivalent:

  • &lt; for <

  • &gt; for >

  • &amp; for &

Range of values is YES and NO. If YES, special characters will be escaped. This parameter is useful if you know your query will return illegal HTML.

p_max_elements

Limit on the number of rows that can be returned by your query. Limits the performance impact of user searches. By entering a value in this parameter, you force the user to search for a narrower set of results.

p_attributes

Additional HTML attributes to use for the form item.

p_ok_to_query

Range of values is YES and NO. If YES, a popup returns first set of rows for the LOV. If NO, a search is initiated to return rows.

p_item_id

ID attribute of the form element.

p_item_label

Invisible label created for the item.


Example

The following example demonstrates a sample query the generates a popup from an LOV named DEPT.

SELECT APEX_ITEM.POPUP_FROM_LOV (1,deptno,'DEPT_LOV') dt 
FROM emp

POPUP_FROM_QUERY Function

This function generates an HTML popup select list from a query. Like other available functions in the APEX_ITEM package, the POPUP_FROM_QUERY function is designed to generate forms with F01 to F50 form array elements.

Syntax

APEX_ITEM.POPUP_FROM_QUERY(

    p_idx              IN    NUMBER,
    p_value            IN    VARCHAR2 DEFAULT,
    p_lov_query        IN    VARCHAR2,
    p_width            IN    VARCHAR2 DEFAULT,
    p_max_length       IN    VARCHAR2 DEFAULT,
    p_form_index       IN    VARCHAR2 DEFAULT,
    p_escape_html      IN    VARCHAR2 DEFAULT,
    p_max_elements     IN    VARCHAR2 DEFAULT,
    p_attributes       IN    VARCHAR2 DEFAULT,
    p_ok_to_query      IN    VARCHAR2 DEFAULT,
    p_item_id          IN    VARCHAR2 DEFAULT NULL,
    p_item_label       IN    VARCHAR2 DEFAULT NULL)
    RETURN VARCHAR2;

POPUPKEY_FROM_LOV Parameters

Parameter Description

p_idx

Identifies a form element name. For example, 1 equals F01 and 2 equals F02. Typically, p_idx is a constant for a given column

Because of the behavior of POPUPKEY_FROM_QUERY, the next index value should be p_idx + 1. For example:

SELECT APEX_ITEM.POPUPKEY_FROM_LOV (1,deptno,'DEPT') dt,
APEX_ITEM.HIDDEN(3,empno) eno

p_value

Indicates the current value. This value should be one of the values in the P_LOV_NAME parameter.

p_lov_name

Identifies a named LOV used for this popup.

p_width

Width of the text box.

p_max_length

Maximum number of characters that can be entered in the text box.

p_form_index

HTML form on the page in which an item is contained. Defaults to 0 and rarely used.

Only use this parameter when it is necessary to embed a custom form in your page template (such as a search field that posts to a different Web site). If this form comes before the #FORM_OPEN# substitution string, then its index is zero and the form opened automatically by Oracle Application Express must be referenced as form 1. This functionality supports the JavaScript used in the popup LOV that passes a value back to a form element.

p_escape_html

Replacements for special characters that require an escaped equivalent.

  • &lt; for <

  • &gt; for >

  • &amp; for &

This parameter is useful if you know your query will return illegal HTML.

p_max_elements

Limit on the number of rows that can be returned by your query. Limits the performance impact of user searches. By entering a value in this parameter, you force the user to search for a narrower set of results.

p_attributes

Additional HTML attributes to use for the form item.

p_ok_to_query

Range of values is YES and NO. If YES, a popup returns the first set of rows for the LOV. If NO, a search is initiated to return rows.


Example

The following example demonstrates how to generate a popup key select list from a shared list of values (LOV).

SELECT APEX_ITEM.POPUPKEY_FROM_LOV (1,deptno,'DEPT') dt 
FROM emp

APEX_APPLICATION

The APEX_APPLICATION package is a PL/SQL package that implements the Oracle Application Express rendering engine. You can use this package to take advantage of a number of global variables. Table: Global Variables Available in APEX_APPLICATION describes the global variables available in the APEX_APPLICATION package.

Global Variables Available in APEX_APPLICATION

Global Variable Description

G_USER

Specifies the currently logged in user.

G_FLOW_ID

Specifies the ID of the currently running application.

G_FLOW_STEP_ID

Specifies the ID of the currently running page.

G_FLOW_OWNER

Specifies the schema to parse for the currently running application.

G_REQUEST

Specifies the value of the request variable most recently passed to or set within the show or accept modules.



Referencing Arrays

Items are typically HTML form elements such as text fields, select lists, and check boxes. When you create a new form item using a wizard, the wizard uses a standard naming format. The naming format provides a handle so you can retrieve the value of the item later on.

If you need to create your own items, you can access them after a page is submitted by referencing APEX_APPLICATION.G_F01 to APEX_APPLICATION.G_F50 arrays. You can create your own HTML form fields by providing the input parameters using the format F01, F02, F03 and so on. You can create up to 50 input parameters ranging from F01 to F50, for example:

<INPUT TYPE="text" NAME="F01" SIZE="32" MAXLENGTH="32" VALUE="some value">
 
<TEXTAREA NAME="F02" ROWS=4 COLS=90 WRAP="VIRTUAL">this is the example of a text area.</TEXTAREA>
 
<SELECT NAME="F03" SIZE="1">
<OPTION VALUE="abc">abc
<OPTION VALUE="123">123
</SELECT> 

Because the F01 to F50 input items are declared as PL/SQL arrays, you can have multiple items named the same value. For example:

<INPUT TYPE="text" NAME="F01" SIZE="32" MAXLENGTH="32" VALUE="array element 1">
<INPUT TYPE="text" NAME="F01" SIZE="32" MAXLENGTH="32" VALUE="array element 2">
<INPUT TYPE="text" NAME="F01" SIZE="32" MAXLENGTH="32" VALUE="array element 3">

Note that following PL/SQL code produces the same HTML as show in the previous example.

FOR i IN 1..3 LOOP
APEX_ITEM.TEXT(P_IDX        => 1,
 p_value      =>'array element '||i ,
 p_size       =>32,
 p_maxlength  =>32);
END LOOP;

Referencing Values Within an On Submit Process

You can reference the values posted by an HTML form using the PL/SQL variable APEX_APPLICATION.G_F01 to APEX_APPLICATION.G_F50. Because this element is an array, you can reference values directly, for example:

FOR i IN 1.. APEX_APPLICATION.G_F01.COUNT LOOP 
    htp.p('element '||I||' has a value of '||APEX_APPLICATION.G_F01(i)); 
END LOOP;

Note that check boxes displayed using APEX_ITEM.CHECKBOX will only contain values in the APEX_APPLICATION arrays for those rows which are checked. Unlike other items (TEXT, TEXTAREA, and DATE_POPUP) which can contain an entry in the corresponding APEX_APPLICATION array for every row submitted, a check box will only have an entry in the APEX_APPLICATION array if it is selected.


Converting an Array to a Single Value

You can also use Oracle Application Express public utility functions to convert an array into a single value. The resulting string value is a colon-separated list of the array element values. The resulting string value is a colon-separated list of the array element values. For example:

htp.p(APEX_UTIL.TABLE_TO_STRING(APEX_APPLICATION.G_F01));

This function enables you to reference G_F01 to G_F50 values in an application process that performs actions on data. The following sample process demonstrates how values are inserted into a table:

INSERT INTO my_table (my_column) VALUES 
APEX_UTIL.TABLE_TO_STRING(APEX_APPLICATION.G_F01)


APEX_CUSTOM_AUTH
