dblink_error_message

Description

dblink_error_message fetches the most recent remote error message for a given connection.

Arguments

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');
