The "does not equal" operator is useful on its own, but it becomes most powerful when combined with an IF function. Let's take a look at a practical example to see how this works.The following example uses the IF function. If you haven't used IF statements yet, check out our IF ...
Compares two expressions (a comparison operator). When you compare nonnull expressions, the result is TRUE if the left operand is not equal to the right operand; otherwise, the result is FALSE. If either or both operands are NULL, see the topic SET ANSI_NULLS (Transact-SQL). Transact-SQL...

true if the left expression is not equal to the right expression; otherwise, false. Example The following Entity SQL query uses the != operator to compare two expressions to determine whether the left expression is not equal to the right expression. The query is based on the AdventureWorks Sal...
