I have an MS SQL server table with 2 fields: Job number, and reason
code. I built an Access form that saves data to the SQL table (through
a linked table). I'm pretty new to this, and am trying to figure out
how to prevent users from entering the same job# twice? I have a save
record button on the form. When I click it, If the job# already exists
in the table, I'd like to show a message saying "job# already exists".
What's the best approach to this?
Thanks,
Troy Sherven
