DBTYPE_WSTR

Not supported

DESCRIPTION

DBTYPE_WSTR

A human-readable description of the measure. NULL if no description exists.

EXPRESSION

The path to be used when displaying the measure in the user interface. Folder names will be separated by a semicolon. Nested folders are indicated by a backslash (\).

DEFAULT_FORMAT_STRING

DBTYPE_WSTR

The default format string for the measure.

The rowset is sorted on CATALOG_NAME, SCHEMA_NAME, CUBE_NAME, MEASURE_NAME.
