bur when I run I get this error:
PLS-00364: loop index variable 'IND_TAB2' use is invalid
the for loop seem correct.
Have someone any idea for this error?

Answer 1

why I must declare ind_tab2 ?You don't.
OR ind_tab2.stato='' will never evaluate to TRUE, you need to use "is null"
I don't know why you are getting the error though, as you don't have any out parameters
