REMARKS

varchar(254)

SQL Server does not return a value for this column.

sp_tables_ex is executed by querying the TABLES rowset of the IDBSchemaRowset interface of the OLE DB provider corresponding to table_server. The table_name, table_schema, table_catalog, and column parameters are passed to this interface to restrict the rows returned.

sp_tables_ex returns an empty result set if the OLE DB provider of the specified linked server does not support the TABLES rowset of the IDBSchemaRowset interface.

Requires SELECT permission on the schema.

The following example returns information about the tables that are contained in the HumanResources schema in the AdventureWorks database on the LONDON2 linked server.

EXEC sp_tables_ex @table_server = 'LONDON2', 
@table_catalog = 'AdventureWorks', 
@table_schema = 'HumanResources', 
@table_type = 'TABLE'
