Answer 1

in fact i have a loop over a cursor :
LOOP
tmp_var:=0;
FETCH contrat_cursor INTO contrat_rec;
          EXIT WHEN contrat_cursor%NOTFOUND;
treatment1 -- i want to put all this trt1 in a function , and the function , since it depend on contrat_rec, will have a parameter
end loop;
in other context i need this function to make some trt in one row of the table contrat
so i can get this row with select * from contrat where ...
my question, is this ok when i give contrat_cursor%ROWTYPE as parameter to the function
and in the second context, when i get back i row from table contrat , how can i give this row as paramer , in contrat_cursor%ROWTYPE form
i wish it was clear
