mysql光标和循环次数。如何计算在MySQL游标循环数

Question

我怎么能算圈数在光标

declare counter int; 

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

set counter := counter + 1; 

    end loop LOOP1; 

，但我得到的错误：

[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

也许你需要删除:在set解决SQL语法错误：

set counter = 1; 

和

set counter = counter + 1;
