The Problem
u Imagine running the example several times:     
u   f_get_Column_tx('emp','eName','empNo',7896)
u   f_get_Column_tx('emp','eName','empNo',4564)
u   f_get_Column_tx('emp','eName','empNo',4546)
uResult:
ØSGA is occupied with exactly the same statements.
u     select eName from emp where empNo=7896
u     select eName from emp where empNo=4564
u     select eName from emp where empNo=4546
ØCPU time is spent re-parsing exactly the same statement.
Hard-coding each and every statement is A VERY BAD THING!
