Base data type Dmapv. A COM interface pointer to a DMA object.

String

DMA_DATATYPE_STRING

Base data type pDmaString. A DMA string. (See the DMA Internationalization and Localization section.)

Any Base Datatype

DMA_DATATYPE_ANY_BASE_DATATYPE

Not a base data type. Indicates that any base data type will be acceptable in the context in which it is used. It is used to specify the base data type of the operand to the operators such as dmaQueryOperator_IsNull and dmaQueryOperator_IsDefined.

Class

DMA_DATATYPE_CLASS

Not a base data type. This value is used as the result type for a join operator, and as the required data type in operand descriptions where a join expression, searchable class or subquery with empty select list is required.

Result Row

DMA_DATATYPE_RESULT_ROW

Not a base data type. This indicates that the value is a query result row object.
