Answer
Hints override optimizer decisions by forcing specific behavior.
They should be used only when the optimizer consistently chooses suboptimal plans.
Quick Answer
A hint forces SQL Server to use a specific index, join type, or behavior instead of letting the optimizer decide. Use sparingly — hints override the optimizer's judgment, which can help in edge cases but often makes things worse long-term as data changes. Prefer fixing statistics or schema over using hints.
