Get the error-message corresponding to the given MySQL error-code, or nullptr if no message is available for that code (this may indicate a bug in the caller).
If error messages have been loaded, return the appropriate message in the configured default language; otherwise, retrieve the message from the compiled-in set (in English).
mysql_errno | MySQL error-code |
an | error-message if available, or nullptr |
const char * error_message_for_client | ( | int | mysql_errno | ) |
Get the error-message corresponding to the given MySQL error-code, or nullptr if no message is available for that code (this may indicate a bug in the caller).
Use this variant for messages intended for sending to a client.
If the session language is known, the message will be returned in that language if available; otherwise, we will fall back on the configured default language if loaded, or finally on the built-in default, English.
mysql_errno | MySQL error-code |
an | error-message if available, or nullptr |
const char * error_message_for_error_log | ( | int | mysql_errno | ) |
Get the error-message corresponding to the given MySQL error-code, or nullptr if no message is available for that code (this may indicate a bug in the caller).
Use this variant for messages intended for the server's error-log.
If error messages have been loaded, return the appropriate message in the configured default language; otherwise, retrieve the message from the compiled-in set (in English).
mysql_errno | MySQL error-code |
an | error-message if available, or nullptr |
bool init_errmessage | ( | ) |
Read the error message file, initialize and register error messages for all languages.
true | if initialization failed, false otherwise. |
int mysql_errno_to_builtin | ( | uint | mysql_errno | ) |
Find the error message record for a given MySQL error code in the array of registered messages.
The result is an index for said array; this value should not be considered stable between subsequent invocations of the server.
mysql_errno | the error code to look for |
-1 | no message registered for this error code |
>=0 | index |
