You can use comparison operators with scalar data in any Data Mining Extensions (DMX) expression in [!INCLUDEmsCoName] [!INCLUDEssNoVersion] [!INCLUDEssASnoversion]. 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.
