1) This is right. Currently MySQL does not have optimization to avoid it.

You could however add LIMIT 1 to all all limits you have which might improve their performance.

2) Right, IF is basically just a function and in MySQL Functions accept number of parameters
and return scalar value. You can execute different queries based on some data by using stored procedures in MySQL 5.0 You can also use number of IF functions to generate the row.

3) If you found a bug please report it on and we'll try to fix it ASAP.
Make sure you're using latest stable version as problem might already be fixed (I remember some fixes in this area)
