B.3.2 Client Error Message Reference

Client error messages originate from within the MySQL client library. Here is an example client error message, as displayed by the mysql client:

shell> mysql -h no-such-host
ERROR 2005 (HY000): Unknown MySQL server host 'no-such-host' (0)

Each client error message includes an error code, SQLSTATE value, and message string, as described in Section B.1, “Error Message Sources and Components”. These components are available as described in Section B.2, “Error Information Interfaces”. For client errors, the SQLSTATE value is always 'HY000' (general error), so it is not meaningful for distinguishing one client error from another.

The client library also makes available to host client programs any errors that originate on the server side and are recieved by the client from the server. For a list of server-side errors, see Section B.3.1, “Server Error Message Reference”.

In addition to the errors in the following list, the client library can also produce error messages that have error codes in the range from 1 to 999. See Section B.3.3, “Global Error Message Reference”
