EnumTables Method

This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.

The EnumTables method returns a QueryResults object that enumerates the tables of a linked server.

object.EnumTables( [ TableName ] , [ SchemaName ] , [ CatalogName ]
, [ TableType ] )as QueryResults

object

Expression that evaluates to an object in the Applies To list.

TableName

Optional. String that identifies a table on the linked server by name. Maps to the OLE DB schema rowset restriction TABLE_NAME. When specified, restricts result set membership to the table(s) matching the criteria.

SchemaName

Optional. String that identifies a schema on the linked server by name. Maps to the OLE DB schema rowset restriction SCHEMA_NAME. When specified, restricts result set membership to tables defined on the schema.

CatalogName

Optional. String that identifies a catalog on the linked server by name. Maps to the OLE DB schema rowset restriction CATALOG_NAME. When specified, restricts result set membership to tables defined on the catalog.

TableType

Optional. Maps to the OLE DB schema rowset restriction TABLE_TYPE. A long integer that specifies a type of table as described in Settings.

HRESULT EnumTables(LPSQLDMOQUERYRESULTS* ppResults,
SQLDMO_LPCSTR TableName = NULL,
SQLDMO_LPCSTR SchemaName = NULL,
SQLDMO_LPCSTR CatalogName = NULL,
SQLDMO_LINKEDTABLE_TYPE TableType = SQLDMOLinkedTable_Default);

The EnumTables method is implemented using the IDBSchemaRowset interface of the OLE DB provider specified by the linked server. The method returns part of the DBSCHEMA_TABLES rowset.

Some OLE DB providers support wildcard matches in restrictions specified by the TableName, SchemaName, and CatalogName arguments of the EnumTables method. Some OLE DB providers return values in the result set columns TABLE_CAT, TABLE_SCHEM, and REMARKS. For more information about argument specification and result set membership interpretation, see the OLE DB provider documentation.
