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

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');
