Microsoft OLE DB 2.0 Programmers Reference and Data Access SDK (Microsoft Professional Editions)
| OLE DB Programmer's Reference |
Multidimensional OLE DB for OLAP provides a syntax called multidimensional expressions (MDX) to specify a dataset. MDX is a set of macros defined on top of SQL. These macros are generally useful for querying a multidimensional data source, and their precise semantics are defined by means of their structured query language mappings.
Multidimensional expressions are discussed in greater detail in Chapter 25: Multidimensional Expressions. Relevant topics include the following:
- Parts of an MDX Statement
- Axis and Slicer Dimensions
- Establishing Cube Context
- Namespace and Unique Names
- Using the OLE DB Command Object
