MySQL 8.0 Reference Manual  /  Errors, Error Codes, and Common Problems  /  Server Error Message Reference

B.3 Server Error Message Reference

The MySQL server writes some error messages to its error log, and sends others to client programs.

Example server-side error messages written to the error log:

2018-10-28T13:01:32.735983Z 0 [Note] [MY-010303] [Server] Skipping
generation of SSL certificates as options related to SSL are specified.

2018-10-02T03:20:39.410387Z 768 [ERROR] [MY-010045] [Server] Event Scheduler:
[evtuser@localhost][myschema.e_daily] Unknown database 'mydb'

Example server-side error message sent to client programs, as displayed by the mysql client:

mysql> SELECT * FROM no_such_table;
ERROR 1146 (42S02): Table 'test.no_such_table' doesn't exist

Each server 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”.
