dblink_error_message

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, orOK if there has been no error in this connection.

Notes

When asynchronous queries are initiated bydblink_send_query, the error message associated with the connection might not get updated until the server's response message is consumed. This typically means thatdblink_is_busy ordblink_get_result should be called prior todblink_error_message, so that any error generated by the asynchronous query will be visible.

Examples

SELECT dblink_error_message('dtest1');
