Re: MySQL get highest value and delete other rows

No primary key? Then it's not a real table, it's not ready for use.

And id columns should not be text---if numeric, should be Smallint or Int, if date then Date, if char then VarChar(n) where n is just big enough to hold the largest value anticipated.

And where is the sample data?
