Applies To: SQL Server 2014, SQL Server 2016 Preview

Executes the specified pass-through query on the specified linked server. This server is an OLE DB data source. OPENQUERY can be referenced in the FROM clause of a query as if it were a table name. OPENQUERY can also be referenced as the target table of an INSERT, UPDATE, or DELETE statement. This is subject to the capabilities of the OLE DB provider. Although the query may return multiple result sets, OPENQUERY returns only the first one.

Applies to: SQL Server (SQL Server 2008 through current version).

OPENQUERY ( linked_server ,'query' )


Is an identifier representing the name of the linked server.


Is the query string executed in the linked server. The maximum length of the string is 8 KB.

OPENQUERY does not accept variables for its arguments.

OPENQUERY cannot be used to execute extended stored procedures on a linked server. However, an extended stored procedure can be executed on a linked server by using a four-part name. For example:

EXEC SeattleSales.master.dbo.xp_msver

Any call to OPENDATASOURCE, OPENQUERY, or OPENROWSET in the FROM clause is evaluated separately and independently from any call to these functions used as the target of the update, even if identical arguments are supplied to the two calls. In particular, filter or join conditions applied on the result of one of those calls have no effect on the results of the other.

Any user can execute OPENQUERY. The permissions that are used to connect to the remote server are obtained from the settings defined for the linked server.

The following example uses a pass-through UPDATE query against the linked server created in example A.

UPDATE OPENQUERY (OracleSvr, 'SELECT name FROM joe.titles WHERE id = 101') 
SET name = 'ADifferentName';

The following example uses a pass-through INSERT query against the linked server created in example A.

INSERT OPENQUERY (OracleSvr, 'SELECT name FROM joe.titles')
VALUES ('NewTitle');

The following example uses a pass-through DELETE query to delete the row inserted in example C.

DELETE OPENQUERY (OracleSvr, 'SELECT name FROM joe.titles WHERE name = ''NewTitle''');
