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

Restriction column CLR data type Description
PROCEDURE_CATALOG string Catalog name. A null value if the provider does not support catalogs.
PROCEDURE_SCHEMA string Unqualified schema name. A null value if the provider does not support schemas.
PROCEDURE_NAME string Procedure name.
COLUMN_NAME string The name of the column; this might not be unique. If this cannot be determined, a null value is returned. 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.
Note   The Procedure_Columns schema is not supported by any OLE DB providers that ship in MDAC version 2.7. Refer to your database documentation to determine whether you can retrieve this schema information by querying the system tables of your database.
