Example
/* Suppose you have a user exit named MYEXIT to which you want to
** pass the values of the SAL column. Suppose, also, that you want
** to raise your own error if the user exit is not found (e.g., because
** it is not linked, compiled, etc.). To do these things, you could
** write the following PL/SQL in the Format Trigger of the F_SAL field:
*/
/* This trigger will raise your message as follows:
** MSG-1000: User exit MYEXIT failed. Call Karen Smith x3455.
*/
