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');
