I have 3 fields zIP, zhostname,zdbname (All text boxes). I need to put a validation so as to restrict the end user from entering a duplicate record for the above fields.
When a user creates a new record and clicks save, it should check in the database if there is any duplicate entry for the above fields & throw a msg stating duplicate entry.
Is it possible to use pdm_list command to achieve this requirement? or kindly suggest any other way.
