# 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, 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'); ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
