使用mysql存儲過程創建分頁

Question

M嘗試使用存儲過程創建分頁，

當我嘗試將1作為參數傳遞時，記錄為0到14。
當我通過2作為參數時，它給出0-30，當我通過2作為參數時，我希望15-30

create PROCEDURE abc(pageno INT)
BEGIN  
DECLARE page_no int;
DECLARE rstarts int;
DECLARE rends int; 
DECLARE userPage int;

set @userPage = pageno;

PREPARE STMT FROM 
" SELECT * FROM primaryinfo LIMIT ?,? "; 
SET @START =(@userPage - 1) * 15; 
SET @LIMIT = @userPage * 15; 
EXECUTE STMT USING @START, @LIMIT;
DEALLOCATE PREPARE STMT;
END

還是有其他有效解決方案。.預先感謝您

沒有聲明的分頁：

create PROCEDURE test(
  IN first_rec integer,
  IN rec_count integer
)
BEGIN
  -- return --
  SET @rownum=0;
  SELECT * FROM (
    SELECT
    user.*, @rownum:=@rownum+1 AS rn FROM user
  ) t WHERE rn>=first_rec and rn<first_rec+rec_count;
END;;
