Please help me out from this problem. How can I remove CONSTRAINT from exist data in Table. I am unable to delete that particular Column.
If you want to delete constraint from a table. You have to check the constraint name by using below query.
Once you will get the constraints name you have to use below query-
Alter table table_name
Drop constraint constraint name.
