When you define a validation rule, PowerBuilder automatically creates the error message that displays by default when users enter an invalid value:
'Item ~'' + @Col + '~' does not pass validation test.'
You can edit the string expression to create a custom error message.
If you are working in the DataWindow painter, you can enter a string expression for the message, but you do not use the @ sign for placeholders. For example, this is the default message:
'Item ~'' + ColumnName + '~' does not pass validation test.'
A validation rule for the Salary column in the Employee table might have the following custom error message associated with it:
Please enter a salary greater than $10,000.'
If users enter a salary less than or equal to $10,000, the custom error message displays.
