mysql游标和计数循环次数。如何计算mysql游标中的循环次数

Question

如何计算光标中的循环次数

declare counter int;

set counter := 1;
    open cursor1;                           
    LOOP1: loop      

set counter := counter + 1; 

    end loop LOOP1;

但我收到错误：

[Err] 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'set counter := counter + 1; 

    end loop LOOP1;

Answer 1

也许您必须删除:中的set才能解决sql语法错误：

set counter = 1;

和

set counter = counter + 1;
