Operators - Comparison

Applies to: SQL Server Analysis Services

You can use comparison operators with scalar data in any Data Mining Extensions (DMX) expression in Microsoft SQL Server Analysis Services. Comparison operators evaluate to a Boolean data type; they return TRUE or FALSE based on the outcome of the tested condition.

The following table identifies the comparison operators that DMX supports.

Operator Description
< (Less Than) (DMX) For arguments that evaluate to a non-null value, returns TRUE if the value of the argument on the left is less than the value of the argument on the right; returns FALSE otherwise. If either argument or both arguments evaluate to a null value, the operator returns a null value.
> (Greater Than) (DMX) For arguments that evaluate to a non-null value, returns TRUE if the value of the argument on the left is greater than the value of the argument on the right; returns FALSE otherwise. If either argument or both arguments evaluate to a null value, the operator returns a null value.
= (Equal To) (DMX) For arguments that evaluate to a non-null value, returns TRUE if the value of the argument on the left is equal to the value of the argument on the right; returns FALSE otherwise. If either argument or both arguments evaluate to a null value, the operator returns a null value.
<> (Not Equal To) (DMX) For arguments that evaluate to a non-null value, returns TRUE if the value of the argument on the left is not equal to the value of the argument on the right; returns FALSE otherwise. If either argument or both arguments evaluate to a null value, the operator returns a null value.
<= (Less Than or Equal To) (DMX) For arguments that evaluate to a non-null value, returns TRUE if the value of the argument on the left is less than or equal to the value of the argument on the right; returns FALSE otherwise. If either argument or both arguments evaluate to a null value, the operator returns a null value.
>= (Greater Than or Equal To) (DMX) For arguments that evaluate to a non-null value, returns TRUE if the value of the argument on the left is greater than or equal to the value of the argument on the right; returns FALSE otherwise. If either argument or both arguments evaluate to a null value, the operator returns a null value.

You can also use comparison operators in DMX statements and functions to look for a condition.
