Common types of SQL CHECK constraints include range checks and limiting columns values.

  • A.True
  • B.False

Answer: A

Correct answer: True

Range checks and lists of permitted values are two of the three common forms, the third being a comparison between two columns of the same row. All three are conditions the DBMS evaluates on every insert and update, so the rule holds however the data arrives - through an application, a script or a manual statement.
