[ic] SQL Statements

[Michelle Wilant]

Big difference -- memory used in the sql call.  Only call what you need -
optimize your queries.  For example, if in the future you added a custom
column to your mysql products table for some text blob, like a description,
the * query will pull all of that information into memory.  Then you are only
going to use a small poriton of it.  By all means only pull what you need.
