BEGIN #Routine body goes here... declare tmp0 VARCHAR(1000); declare tmp1 VARCHAR(1000);
declare done int default -1;-- 用于控制循环是否结束
/* 声明游标 */
declare myCursor cursor for select name,address from ads_building_info;
/* 当游标到达尾部时,mysql自动设置done=1 */ declare continue handler for not found set done=1;
/* 打开游标 */ open myCursor;
/* 循环开始 */ myLoop: LOOP
/* 移动游标并赋值 */ fetch myCursor into tmp0,tmp1; if done = 1 then leave myLoop; end if;
/* do something */
-- 循环输出信息
insert into test_demo (name,address) VALUES (tmp0,tmp1);
end loop myLoop;
close myCursor;
END
