Disabled Check Constraint
Check constraints are often disabled when bulk loading data into a table to improve performance. It's easy to forget to re-enable them after the event, meaning the check constraint is no longer applied.
💡 Aireforge Advisor can automatically generate a script for this.
- Re-enable the constraint, if still needed. Note that re-enabling the constraint will cause all rows to be checked against the constraint, so this should be considered when scheduling the SQL.
- Drop the constraint if no longer needed.
