My experience with this is that QoQ are are (really) slow when compared with using structs or arrays. I had a one experience where it brought execution time down from 15-20 seconds using QoQ to 1 or 2 seconds for an array. Generally I create an array of the values I want to look up.
EmpArray[1][ID] = tblEmp.Fname EmpArray[2][ID] = tblEmp.Email etc... Even if you use a sub query or a Join to pull these values you are going to hitting the tblEmp table for every record. This way you only hit tblEmp once.. But then again with proper indexes the database route may be faster... so 6 of one or 1/2 dozen of another. G!
