I have a MyISAM table with about 10 million rows.
When I drop the (multi-column) Primary Key (PK) it takes more than 10 minutes.
I thought that any key or index was a kind of table in itself.
And if so, dropping the PK could be as fast as a Truncate statement (a second).

There's no ON clause for a join specified by a WHERE clause, and
I'm getting locking issues due to tables very often updated/insert.
It's splitted into two tables, one has the more updated data and the another
has the more static data. I'm using queries with JOIN, would it be better
for performance to use two queries instead of using JOIN?
