NVL2 requires 3 arguments and it doesnt have to be the same data type NVL requires 2 arguments and it must be the same datatype or something that is implicitly converted

NVL2(STH,1,'X') - doesn't work, needs same or converted data type, but reverse order of parameters works. You can't use NUMBER before VARCHAR in NVL2.

NVL2(STH,1,'X') does not work because 'X' cant be converted to a number, if it was '1' like NVL2(STH,1,'1') it works.
