When declaring variables you must also specify the block where the variables are going to be used.
- attrId = Variable name
- ':=' = Sets the variable to a value
DECLARE
attrId number;
BEGIN
attId:= seq_attr.nextval;
dbms_output.put_line (attId);
END;
Collections
DECLARE
TYPE MyListType IS TABLE OF VARCHAR(21);
myList MyListType := MyListType('option1', 'option2', 'option2');
BEGIN
FOR x IN codes.FIRST .. codes.LAST
LOOP
dbms_output.put_line('COURSE:' || codes(x));
END LOOP;
END;
