sp_remote_imported_keys system procedure

Provides information about remote tables with primary keys that correspond to a specified foreign key.

The server must be defined with the CREATE SERVER statement to use this system procedure.

Syntax

sp_remote_imported_keys( 
@server_name
 , @sp_name
 [, @sp_owner
 [, @sp_qualifier ] ]
)

Arguments

@server_name Use this optional CHAR(128) parameter to specify the server the foreign key table is located on. A value is required for this parameter.
@sp_name Use this optional CHAR(128) parameter to specify the table containing the foreign key. A value is required for this parameter.
@sp_owner Use this optional CHAR(128) parameter to specify the foreign key table's owner.
@sp_qualifier Use this optional CHAR(128) parameter to specify the database containing the foreign key table.

Result set

Column name	Data type	Description
pk_database	CHAR(128)	The database containing the primary key table.
pk_owner	CHAR(128)	The owner of the primary key table.
pk_table	CHAR(128)	The primary key table.
pk_column	CHAR(128)	The name of the primary key column.
fk_database	CHAR(128)	The database containing the foreign key table.
fk_owner	CHAR(128)	The foreign key table's owner.
fk_table	CHAR(128)	The foreign key table.
fk_column	CHAR(128)	The name of the foreign key column.
key_seq	SMALLINT	The key sequence number.
fk_name	CHAR(128)	The foreign key name.
pk_name	CHAR(128)	The primary key name.

Remarks

Foreign keys reference a row in a separate table that contains the corresponding primary key. This procedure allows you to obtain a list of the remote tables with primary keys that correspond to a particular foreign table. The sp_remote_imported_keys result set includes the database, owner, table, column, and name for both the primary and the foreign key, and the foreign key sequence for the foreign key columns. The result set may vary because of the underlying ODBC and JDBC calls, but information about the table and column for a primary key is always returned.

Example

To get information about the tables with primary keys that correspond to a foreign key on the SYSOBJECTS table in the asetest server:

CALL sp_remote_imported_keys(
     @server_name='asetest',
     @sp_name='sysobjects',
     @sp_qualifier='production' );
