I agree with Anonymous Monk that there is nothing wrong with using two SQL statements in this situation. But what is the function of the subroutine to which you want to pass the value of COLUMN3 ? Could you use an existing SQL function in your SELECT query? Or could you build a stored routine for your DB?

Built-in SQL functions
Stored routines in MySQL


The way forward always starts with a minimal test.
