dblink_error_message
Name
dblink_error_message -- gets last error message on the named connection
Synopsis
dblink_error_message(text connname) returns text
Description
dblink_error_message fetches the most recent remote error message for a given connection.
Arguments
- connname
-
Name of the connection to use.
Return Value
Returns last error message, or OK if there has been no error in this connection.
Notes
When asynchronous queries are initiated by dblink_send_query, the error message associated with the connection might not get updated until the server's response message is consumed. This typically means that dblink_is_busy or dblink_get_result should be called prior to dblink_error_message, so that any error generated by the asynchronous query will be visible.
Examples
SELECT dblink_error_message('dtest1');
