Microsoft OLE DB 2.0 Programmers Reference and Data Access SDK (Microsoft Professional Editions)
| OLE DB Programmer's Reference |
The command object supports text commands in the MDX syntax by using the OLE DB ICommandText interface. Consumers use ICommandText::SetCommandText to specify the command and ICommand::Execute to process the command. For commands that may be used several times, consumers can prepare the command with ICommandPrepare::Prepare. For a complete discussion of the OLE DB command object, see "Command Objects" in Chapter 1: Overview of OLE DB. For additional information about the MDX syntax defined by OLE DB for OLAP and its use, see "Datasets and Multidimensional Expressions" in Chapter 22: OLE DB for OLAP Concepts. Also see Chapter 25: Multidimensional Expressions.
OLE DB for OLAP defines a GUID that denotes the MDX syntax: MDGUID_MDX. This GUID is used in ICommandText::SetCommandText to notify the provider that the query language being used is the MDX syntax defined in Chapter 26: MDX Grammar.
