Comparison Operators (DMX)
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 |
|---|---|
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. |
|
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. |
|
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. |

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