Can't drop primary key?

    Hi

    I'm struggling to drop a primary key.

    I get the error:

    An explicit DROP INDEX is not allowed on index 'MyTable.PrimaryKey'. It is being used for FOREIGN KEY constraint enforcement.

    "sp_helpindex MyTable", returns 1 entry:

    PrimaryKey, nonclustered, unique located on PRIMARY, ID

    I also tried:

    alter table MyTable DROP CONSTRAINT PrimaryKey

    I even went as far as dropping all primary keys and foreign keys on the entire database, but the error still pops up. Any ideas?

    what results do you get when you run EXEC sp_fkeys myTable?

    OK - thanks. I found a couple of FK's, and I've removed it manually and it's working now.
