Compares two expressions (a comparison operator) in SQL Server 2017 When you compare nonnull expressions, the result is TRUE if the left operand has a value higher than the right operand; otherwise, the result is FALSE. If either or both operands are NULL, see the topic SET ANSI_NULLS (Transact-SQL).
