  • 0

Whenever we have to update the database; we delete the values from the table first and then add the latest values. This ensures that everything is updated correctly.

This adds little bit overhead to the system but we haven’t faced any performance issues because of this.

Is this always the best thing to do?

    Use the UPDATE statement.

    Additionally, if you worried about integrity, scope it within a transaction:

    BEGIN TRAN T1  -- This update is part of T1 UPDATE Table1 SET Col1='New Value' WHERE Col2 = @Id;  -- Time to commit your changes.  -- If for any reason something fails,  -- everything gets rolled back COMMIT TRAN T1
