What I want to achive it's a routine, as a function or procedure with parametres, in the script.
What for? Because of Incremental Load.
The code I have for incremental Load, goes before the table. So, if i have 20 tables i'd have to copy the mentioned code before each one. It'd be perfect to create a function and call it before each table giving it parametres, as the name of the table and others if necesary.
