dblink_cancel_query
dblink_cancel_query
dblink_cancel_query - cancels any active query on the named connection
Synopsis
dblink_cancel_query(text connname) returns text
Description
dblink_cancel_query
attempts to cancel any query that
is in progress on the named connection. Note that this is not
certain to succeed (since, for example, the remote query might
already have finished). A cancel request simply improves the
odds that the query will fail soon. You must still complete the
normal query protocol, for example by calling
dblink_get_result
.
Arguments
-
connname -
Name of the connection to use.
Return Value
Returns
OK
if the cancel request has been sent, or
the text of an error message on failure.
Examples
SELECT dblink_cancel_query('dtest1');
