LEVELS Rowset
The LEVELS rowset contains information about the levels available in a dimension.
The default sort order is CATALOG_NAME, SCHEMA_NAME, CUBE_NAME, DIMENSION_UNIQUE_NAME, HIERARCHY_UNIQUE_NAME, and LEVEL_NUMBER.
The rowset structure is described in the following table.
Column name |
Type indicator |
Description |
---|---|---|
CATALOG_NAME |
DBTYPE_WSTR |
Optional. The name of the catalog to which this level belongs. NULL if the provider does not support catalogs. |
SCHEMA_NAME |
DBTYPE_WSTR |
Optional. The name of the schema to which this level belongs. NULL if the provider does not support schemas. |
CUBE_NAME |
DBTYPE_WSTR |
Required. Name of the cube to which this level belongs. |
DIMENSION_UNIQUE_NAME |
DBTYPE_WSTR |
Required. Unique name of the dimension to which this level belongs. For providers that generate unique names by qualification, each component of this name is delimited. |
HIERARCHY_UNIQUE_NAME |
DBTYE_WSTR |
Required. Unique name of the hierarchy. If the level belongs to more than one hierarchy, there is one row for each hierarchy to which it belongs. For providers that generate unique names by qualification, each component of this name is delimited. |
LEVEL_NAME |
DBTYPE_WSTR |
Required. Name of the level. |
LEVEL_UNIQUE_NAME |
DBTYPE_WSTR |
Required. Unique name of the level. For providers that generate unique names by qualification, each component of this name is delimited. |
LEVEL_GUID |
DBTYPE_GUID |
Optional. Level GUID. NULL if the level does not have a GUID. |
LEVEL_CAPTION |
DBTYPE_WSTR |
Required. A label or caption associated with the hierarchy. Used primarily for display purposes. If a caption does not exist, LEVEL_NAME is returned. |
LEVEL_NUMBER |
DBTYPE_UI4 |
Required. The distance of the level from the root of the hierarchy. The root level is zero. |
LEVEL_CARDINALITY |
DBTYPE_UI4 |
Required. The number of members in a level. This value can be an approximation of the real cardinality. Consumers should not assume that this value is accurate. |
LEVEL_TYPE |
DBTYPE_I4 |
Required. The following bitmasks are used to specify the level characteristics:
Note
The LEVEL_TYPE column exists mainly as a means to transmit formatting instructions to an application. For example, a level with a type of LEVEL_TYPE_TIME_DAYS might indicate to an application that the members of the level should be expressed in text format (that is, "Sunday", "Monday", "Tuesday", and so on). LEVEL_TYPE_REGULAR can be used to signify a level that does not require any special formatting.

DESCRIPTION |
DBTYPE_WSTR |
Optional. A human-readable description of the level. NULL if no description exists. |
