Check Candidate Columns for NOT NULL Constraints

By Charles Jacobus,

You can use the output of this script to decide whether the definition of the candidate columns could be changed to enforce a NOT NULL constraint. By not allowing NULL values, you can help simplify queries and avoid data ambiguity.

To use the script, simply execute it against a target database. In the event that the account you’re running the script under doesn’t have SELECT permission on a table, that table is reported through the @SkippedTablesT table variable (so you know the table was skipped).
