The following table identifies the logical operators that DMX supports. |Operator|Description| |--------------|-----------------| |[AND (DMX)](../dmx/and-dmx.md)|Performs a logical conjunction on two numeric expressions.| |[NOT (DMX)](../dmx/not-dmx.md)|Performs a logical negation on a numeric expression.| |[OR (DMX)](../dmx/or-dmx.md)|Performs a logical disjunction on two numeric expressions.| ## See Also [Data Mining Extensions (DMX) Reference](../dmx/data-mining-extensions-dmx-reference.md) [Data Mining Extensions (DMX) Function Reference](../dmx/data-mining-extensions-dmx-function-reference.md) [Data Mining Extensions (DMX) Operator Reference](../dmx/data-mining-extensions-dmx-operator-reference.md) [Data Mining Extensions (DMX) Statement Reference](../dmx/data-mining-extensions-dmx-statements.md) [Data Mining Extensions (DMX) Syntax Conventions](../dmx/data-mining-extensions-dmx-syntax-conventions.md) [Data Mining Extensions (DMX) Syntax Elements](../dmx/data-mining-extensions-dmx-syntax-elements.md) [Expressions (DMX)](../dmx/expressions-dmx.md) [General Prediction Functions (DMX)](../dmx/general-prediction-functions-dmx.md) [Operators (DMX)](../dmx/operators-dmx.md) [Structure and Usage of DMX Prediction Queries](../dmx/structure-and-usage-of-dmx-prediction-queries.md) [Understanding the DMX Select Statement](../dmx/understanding-the-dmx-select-statement.md)
