13.7 ADD_ERROR Procedure Signature 5

This procedure adds an error message to the error stack of a tabular form that is used to display text as defined by a shared component. This error message can be displayed to all display locations. It can be called in a validation or process to add one or more errors to the error stack.

Note:

This procedure must be called before the Application Express application has performed the last validation or process. Otherwise, the error is ignored if it does not have a display location of apex_error.c_on_error_page.

Parameters	Description
`p_error_code`	Name of shared component text message.
`p0` through `p9`	Values for %0 through %9 placeholders defined in the text message.

`p_column_alias`	The name of the tabular form column alias defined for `p_region_id` that is highlighted if `apex_error.c_inline_with_field` or `apex_error.c_inline_with_field_and_notif` are used as a display location.

Example

This example illustrates how to add a custom error message, where the text is stored in a text message, to the error stack. The CUSTOMER_ID column on the tabular form is highlighted. The error message is displayed inline in a notification. This example can be used in a validation or process.

apex_error.add_error (
    p_error_code       => 'INVALID_CUSTOMER_ID',
    p0                 => l_customer_id,
    p_display_location => apex_error.c_inline_with_field_and_notif,
    p_region_id        => l_region_id,
    p_column_alias     => 'CUSTOMER_ID',
    p_row_num          => l_row_num );
