hi all ,
i'm trying to improve performance of a quite big and heavily used mysql
set of tables.
i want to create some indexes on this table , but before this , i'd like
to remove the ones created by my predecessor , which are sometimes

here is an output from

mysql drop index login connexion on v2easy0_users;
ERROR 1064: You have an error in your SQL syntax near 'connexion on
v2easy0_users' at line 1
