    p_primary_text_string IN VARCHAR2 DEFAULT NULL,
    p0 IN VARCHAR2 DEFAULT NULL,
    p1 IN VARCHAR2 DEFAULT NULL,
    p2 IN VARCHAR2 DEFAULT NULL,
    ...
    p9 IN VARCHAR2 DEFAULT NULL,

LANG Parameters

Parameter Description

Parameter	Description
`p_primary_text_string`	Text string of the primary language. This will be the value of the Translate From Text in the dynamic translation.
`p_p0` through `p_p9`	Dynamic substitution value: p0 corresponds to 0% in the translation string; p1 corresponds to 1% in the translation string; p2 corresponds to 2% in the translation string, and so on.
`p_primary_language`	Language code for the message to be retrieved. If not specified, Oracle Application Express uses the current language for the user as defined in the Application Language Derived From attribute. See also: Specifying the Primary Language for an Application in the Oracle Application Express Application Builder User's Guide.

p_primary_text_string

Text string of the primary language. This will be the value of the Translate From Text in the dynamic translation.

p_p0 through p_p9

Dynamic substitution value: p0 corresponds to 0% in the translation string; p1 corresponds to 1% in the translation string; p2 corresponds to 2% in the translation string, and so on.

p_primary_language

Language code for the message to be retrieved. If not specified, Oracle Application Express uses the current language for the user as defined in the Application Language Derived From attribute.

Example

Suppose you have a table that defines all primary colors. You could define a dynamic message for each color and then apply the LANG function to the defined values in a query. For example:

SELECT APEX_LANG.LANG(color)
FROM my_colors

If you were running the application in German, RED was a value for the color column in the my_colors table, and you defined the German word for red, the previous example would return ROT.
