DBLINK_ERROR_MESSAGE(3) | PostgreSQL 16.4 Documentation | DBLINK_ERROR_MESSAGE(3) |
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');
