FOR loop_counter IN [REVERSE] lower_bound .. higher_bound LOOP sequence_of_statements; END LOOP; 1. 2. 3. 4. FOR循环自动创建迭代器整形的loop_counter, 而不用人为声明,loop_counter的作用域为FOR循环本身,从lower_bound开始,每次循环加1,直到大于higher_bound,循环退出。 lower_bound必须小于或者等于...
PL/SQL允许在运行时动态地确定循环范围。 示例 以下示例演示如何使用for循环 - SETSERVEROUTPUTONSIZE100000;DECLAREa number(2);BEGINFORain10..20LOOP dbms_output.put_line('value of a: '||a);ENDLOOP;END;/ 当上述代码在SQL提示符下执行时,它会产生以下结果 - 反转FOR LOOP语句 默认情况下,迭代从初始...
