I understood that in the Loop you can change the values of a variable! Exactly what I needed. but unfortunately all of this seems to be temporary. Consequently, the record in the table won't be updated by the changes we made on the local variable even if it points to a record in the table. I forgot the aspect of the cursor that is temporary.
But in all the case, It could be a great improvement to let the syntax modify directly the table.
I think I will find another way to do it. with EXECUTE!!
Best regards

What do you mean by "the record doen't accept the new value"?
Can you show us some SQL statements that exhibit the problem?
