EnumTables Method
Microsoft SQL Server의 이후 버전에서는 이 기능이 제거됩니다. 새 개발 작업에서는 이 기능을 사용하지 않도록 하고, 현재 이 기능을 사용하는 응용 프로그램은 수정하십시오.
The EnumTables method returns a QueryResults object that enumerates the tables of a linked server.

, [ TableType ] )as QueryResults
Parts
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.

주의
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.
