20 APEX_UI_DEFAULT_UPDATE

The APEX_UI_DEFAULT_UPDATE package provides procedures to access user interface defaults from within SQL Developer or SQL*Plus.

You can use this package to set the user interface defaults associated with a table within a schema. The package must be called from within the schema that owns the table you are updating.

User interface defaults enable you to assign default user interface properties to a table, column, or view within a specified schema. When you create a form or report using a wizard, the wizard uses this information to create default values for region and item properties. Utilizing user interface defaults can save valuable development time and has the added benefit of providing consistency across multiple pages in an application.

Topics:


ADD_AD_COLUMN Procedure

Adds a User Interface Default Attribute Dictionary entry with the provided definition. Up to three synonyms can be provided during the creation. Additional synonyms can be added post-creation using apex_ui_default_update.add_ad_synonym. Synonyms share the column definition of their base column.

Syntax

APEX_UI_DEFAULT_UPDATE.ADD_AD_COLUMN (
    p_column_name           IN  VARCHAR2,

    p_help_text             IN  VARCHAR2  DEFAULT NULL,
    p_format_mask           IN  VARCHAR2  DEFAULT NULL,
    p_default_value         IN  VARCHAR2  DEFAULT NULL,
    p_form_format_mask      IN  VARCHAR2  DEFAULT NULL,
