The only time you will gain a speed advantage is if you have no variable >>length fields in your record (varchar, text, etc.). You may notice that >>all your CHAR fields are changed to VARCHAR as soon as a variable length >>field type is added. CHAR is less efficient from a space storage point >> >>
On that note, I've often wanted to be able to do something along the lines of: ALTER TABLE foo USE CHAR; ALTER TABLE foo USE VARCHAR; ... and just port the current max-length values between the two, while changing all relevant columns. -- Michael T.
