XML Data Types (XMLA)

In addition to the standard primitive and derived types defined by the XML 1.0 recommendation, the XML for Analysis (XMLA) 1.1 specification defines additional data types to support the representation of multidimensional and tabular data.

XMLA uses the data types listed in the following table.

Data types Description

Boolean

The standard XML boolean data type.

Decimal

The standard XML decimal data type.

EmptyResult

A namespace on the root element. This namespace is returned when an XMLA command does not return a result because either the XMLA command does not normally return a result or because an error occurred on the Microsoft SQL Server 2005 Analysis Services (SSAS) instance while executing the XMLA command.

EnumString

A set of named string constants for a given enumerator.

Integer

The standard XML int data type.

MDDataSet

Multidimensional data returned by the Result parameter of the Execute method.

Resultset

A self-describing XML result set returned by the Execute method.

Rowset

Rows from a data source, structured by an embedded XML schema, returned by the Discover method.

String

The XML string data type.

UnsignedInt

The XML unsignedInt schema type.

For complete descriptions of the standard XML data types, see the World Wide Web Consortium (WC3) candidate recommendation.
