OK, for one SELECT * is -=ALWAYS=- slower than naming rows, so "Method B"
will have an inherant delay in it before you get anywhere
If you use SELECT * anywhere, you should change it to the names of the
fields
I tend to use INSERT INTO () SELECT FROM as you can specify which fields map
to which fields, and specify values instead of fields
