Installing a MySQL UDF errors with Function already exists· 1 minute read
When installing a UDF recently I got an annoying error message, which didn’t seem to want to go away. Deleting the function before attempting to remove it did not work so I used the following set of escalating commands to attempt to get it to install.
But back to the error for a moment:
bash > mysql -u user -p < installdb.sql Enter password: ERROR 1125 (HY000) at line 7: Function 'lib_mysqludf_ssdeep_info' already exists
This can be solved really simply with the following options:
- Attempt to delete the function and then reinstall it
- Delete the function row from the mysql.func table and then reinstall it
- Stop the MySQL server (after trying option 2), start it again and then reinstall it
