Ah, it's not SQlite... Interesting...

So my question is : how to create DB indexes and triggers with an internal
solution. When i look in bugzilla, some users have investigated and see
that mysql indexes creation need granted privileges since immodb DB engine
is used. And this is true : i reproduced the dysfunction and fixed it.

Or perhaps Amarok do not use Indexes and triggers. In this case, DB
performances will just down...
Or perhaps Amarok do not use immodb engine...
