SELECT_LIST Function

This function dynamically generates a static select list. Similar to other functions available in the APEX_ITEM package, these select list functions are designed to generate forms with F01 to F50 form array elements.

Syntax

APEX_ITEM.SELECT_LIST(
    p_idx           IN   NUMBER,
    p_value         IN   VARCHAR2 DEFAULT NULL,
    p_list_values   IN   VARCHAR2 DEFAULT NULL,
    p_attributes    IN   VARCHAR2 DEFAULT NULL,
    p_show_null     IN   VARCHAR2 DEFAULT 'NO',
    p_null_value    IN   VARCHAR2 DEFAULT '%NULL%',
    p_null_text     IN   VARCHAR2 DEFAULT '%',
    p_item_id       IN   VARCHAR2 DEFAULT NULL,
    p_item_label    IN   VARCHAR2 DEFAULT NULL,
    p_show_extra    IN   VARCHAR2 DEFAULT 'YES')
    RETURN VARCHAR2;

Parameters

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

SELECT_LIST Parameters

Parameter Description

p_idx

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

p_value

Current value. This value should be a value in the P_LIST_VALUES parameter.

p_list_values

List of static values separated by commas. Displays values and returns values that are separated by semicolons.

Note that this is only available in the SELECT_LIST function.

p_attributes

Extra HTML parameters you want to add.

p_show_null

Extra select option to enable the NULL selection. Range of values is YES and NO.

p_null_value

Value to be returned when a user selects the NULL option. Only relevant when p_show_null equals YES.

p_null_text

Value to be displayed when a user selects the NULL option. Only relevant when p_show_null equals YES.

p_item_id

HTML attribute ID for the <input> tag.

p_item_label

Invisible lable created for the item.

p_show_extra

Shows the current value even if the value of p_value is not located in the select list.


Example

The following example demonstrates a static select list that displays Yes, returns Y, defaults to Y, and generates a F01 form item.

SELECT APEX_ITEM.SELECT_LIST(1,'Y','Yes;Y,No;N')yn 
FROM emp

The following example demonstrates the use of APEX_ITEM.SELECT_LIST to generate a static select list where:

SELECT  empno "Employee #", 
    ename "Name",
    APEX_ITEM.SELECT_LIST(
        p_idx           =>   3,
        p_value         =>   deptno,
        p_list_values   =>   'ACCOUNTING;10,RESEARCH;20,SALES;30,OPERATIONS;40',
        p_attributes    =>   'style="color:red;"',
        p_show_null     =>   'YES',
        p_null_value    =>   NULL,
        p_null_text     =>   '-Select-',
        p_item_id       =>   'f03_#ROWNUM#',
        p_item_label    =>   'Label for f03_#ROWNUM#',
        p_show_extra    =>   'YES') "Department"
  FROM  emp;
