dblink_close
Name
dblink_close -- closes a cursor in a
remote database
Synopsis
dblink_close(text cursorname [, bool fail_on_error]) returns text
dblink_close(text connname, text cursorname [, bool fail_on_error]) returns text
Description
dblink_close closes a cursor
previously opened with dblink_open.
Arguments
- connname
-
Name of the connection to use; omit this parameter to
use the unnamed connection.
- cursorname
-
The name of the cursor to close.
- 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
If dblink_open started an
explicit transaction block, and this is the last remaining open
cursor in this connection, dblink_close will issue the matching COMMIT.
