Use this trigger to provide greater control over your form by restricting [Quoted] [Quoted] what the users can do. The only line in the trigger is NULL; Then activate [Quoted] only the keys you want active, for example Execute Query, with the [Quoted] corresponding function in the key's trigger: Key-ExeQry is EXECUTE_QUERY;

[Quoted] [Quoted] In a GUI environment, however, this technique is probably passe'.

This is the only system variable you can change; the others are read-only. [Quoted] [Quoted] Oracle error messages have severity levels, and the lowest-severity messages [Quoted] [Quoted] are only informational. To prevent unnecessary messages from being displayed [Quoted] by a procedure, increase the message_level before executing the procedure.

[Quoted] [Quoted] An example is FRM-40301...no records...retrieved resulting from an Execute_Query. This may be a nuisance message in some situations, and it can [Quoted] be supressed by setting message_level to 30 before the Execute_query [Quoted] statement. (Be sure to set message_level back to its previous value after the query.)
