# 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');
```
