mysql光標和循環次數。如何計算在MySQL遊標循環數

Question

我怎麼能算圈數在光標

declare counter int; 

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

set counter := counter + 1; 

    end loop LOOP1; 

，但我得到的錯誤：

[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

也許你需要刪除:在set解決SQL語法錯誤：

set counter = 1; 

和

set counter = counter + 1;
