True False Y N

Working with affiliate data files

[aijohn]

I'm setting up a MYSQL database to use date files from affiliates.

Looking for suggestions on accepted practices for field type when data is
True False
Y N
0 1

0 and 1 are always nice :)

I was wondering if there were any performance differences between using int, varchar(5), boolean etc. in mysql

Yes, there will be differences (in storage requirements as well as performance), but miniscule unless you're talking about millions of rows.

It is always good practice to use the most efficient field type you can - boolean (bit) in this case - assuming you are running MySQL 5.0.3+
