Sounds simple but I seem to have a tough time in dropping a primary key on a table in mysql – Have a table CompanyList with CompID as the primary key. It is being used as a foreign key in a bunch couple of other tables in the database.

I want to retain the field CompID but I do not want it to be the primary key.

I tried removing the primary key from CompID but got the error.

ERROR: Error when running failback script. Details follow.
ERROR 1050: Table ‘CompanyList’ already exists

Should I drop all the foreign key references in order to achieve this.

Any help would be greatly appreciated.

    Yes, you have to drop all FOREIGN KEYs to drop the PRIMARY KEY they reference.
