Hi Friends, 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). Am I missing something here ? I am using MySQL version 5.0.15. TIA. Cor
