dblink_open
DBLINK_OPEN(3) PostgreSQL 9.2.7 Documentation DBLINK_OPEN(3)NAME
dblink_open - opens a cursor in a remote database
SYNOPSIS
dblink_open(text cursorname, text sql [, bool fail_on_error]) returns text
dblink_open(text connname, text cursorname, text sql [, bool fail_on_error]) returns text
DESCRIPTION
dblink_open() opens a cursor in a remote database. The cursor can subsequently be manipulated with dblink_fetch() and dblink_close().
ARGUMENTS
conname
Name of the connection to use; omit this parameter to use the unnamed connection.
cursorname
The name to assign to this cursor.
sql
The SELECT statement that you wish to execute in the remote database, for example select * from pg_class.
fail_on_error
If true (the default when omitted) then an error thrown on the remote side of the connection causes an error to also be thrown locally.
If false, the remote error is locally reported as a NOTICE, and the function's return value is set to ERROR.
RETURN VALUE
Returns status, either OK or ERROR.
NOTES
Since a cursor can only persist within a transaction, dblink_open starts an explicit transaction block (BEGIN) on the remote side, if the
remote side was not already within a transaction. This transaction will be closed again when the matching dblink_close is executed. Note
that if you use dblink_exec to change data between dblink_open and dblink_close, and then an error occurs or you use dblink_disconnect
before dblink_close, your change will be lost because the transaction will be aborted.
EXAMPLES
SELECT dblink_connect('dbname=postgres');
dblink_connect
----------------
OK
(1 row)
SELECT dblink_open('foo', 'select proname, prosrc from pg_proc');
dblink_open
-------------
OK
(1 row)
