PLSQL：为光标运行FORloop，最后一行打印两次

Question

现在，我要做的就是将光标中的值打印在另一个下方。 最后一行被打印两次。

IF c_rules_present %ISOPEN THEN
         CLOSE c_rules_present ;
        END IF;
        OPEN c_rules_present;
            LOOP
                FETCH c_rules_present INTO rule_present_record;
                dbms_output.put_line(rule_present_record.rdr_dcd_cndtn);
                EXIT WHEN c_rules_present %notfound;
            END LOOP;
        CLOSE   c_rules_present;

只需将EXIT WHEN条件向上移动：

IF c_rules_present %ISOPEN THEN
         CLOSE c_rules_present ;
        END IF;
        OPEN c_rules_present;
            LOOP
                FETCH c_rules_present INTO rule_present_record;
                EXIT WHEN c_rules_present %notfound;
                dbms_output.put_line(rule_present_record.rdr_dcd_cndtn);
            END LOOP;
        CLOSE   c_rules_present;
