I am trying to check to see if a record already exist before it is inserted to a table, if it does exist I will like a message to display or highlight the record and NOT insert that record. Any suggestions on how to do this ?

I was thinking of some sort of cursor in my form and if it is found display a message, I searched the entries in the forum and found none that could help.

Any help is appreciated.

I have an unique index on the table, but my question is if the user tries to insert a record that already exist, i would like to display some sort of warning, how do I do that if the entry they are trying to insert coming from a form?

I got it, thanks. I added an exception where the insert was occurring on the form and displayed a message and changed foreground color of record that was a duplicate.

message('You have duplicate records!');

set_item_instance_property('EMPL_MASTER.EMP_FULL_NAME',current_record,VISUAL_ATTRIBUTE, 'DUPLICATE_EXIST');
