Remarks

Column_Domain_Usage maps to the OLE DB COLUMN_DOMAIN_USAGE rowset. Unless otherwise specified, restriction columns are returned in the following order.

Restriction column CLR data type Description
DOMAIN_CATALOG string Catalog name. A null value if the provider does not support catalogs.
DOMAIN_SCHEMA string Unqualified schema name. A null value if the provider does not support schemas.
DOMAIN_NAME string View name.
COLUMN_NAME string Column name. This column, together with the COLUMN_GUID and COLUMN_PROPID columns, forms the column ID. One or more of these columns will be a null value, depending on which elements of the DBID structure the provider uses. (DBID is a formal structure serialized into the COLUMN_NAME column of the COLUMN_DOMAIN_USAGE rowset.)
