我有兩個過程，其中我使用limit子句進行動態查詢，然後從中準備語句並執行。SQL_CALC_FOUND_ROWS不在mysql中工作

的第一道工序的最終查詢是
SELECT SQL_CALC_FOUND_ROWS mo.month_name as date,ifnull(sales,0) as sales,IFNULL(refunds,0) as refunds,IFNULL(partially_refunded,0) as partially_refunded,ifnull(pending,0) as pending,ifnull(pending_revenue,0) as pending_revenue,ifnull(gross_revenue,0) as gross_revenue,IFNULL(total_outflow,0) AS total_outflow,IFNULL(net_revenue,0) AS net_revenue,IFNULL(refund_percentage,0) AS refund_percentage,IFNULL(partially_refund_percentage,0) AS partially_refund_percentage,IFNULL(pending_percentage,0) AS pending_percentage,IFNULL(overall_outflow_percentage,0) AS overall_outflow_percentage,IFNULL(supervisor,0) AS supervisor,IFNULL(product,"") AS product,IFNULL(campaign,"") AS campaign,IFNULL(agent_location,"") AS agent_location,IFNULL(country,"") AS country FROM master_months mo LEFT JOIN tmp_result ON mo.month_name = `date` ORDER BY mo.month_id ASC LIMIT 0,5
現在，當我之後它返回5，但總記錄上述程序火
select FOUND_ROWS();
是110.
在第二個過程最終的查詢是
select SQL_CALC_FOUND_ROWS * from customer_detail cd
left join user_detail ud on cd.created_by = ud.user_id order by ud.user_id limit 1,6
現在，當我火
select FOUND_ROWS()
此過程後，回到實際數量是1015
，如果我直接運行這兩個查詢那麼found_rows（）將返回實際的總記錄。這兩個查詢之間唯一的區別在於第一個查詢是在像count這樣的查詢中進行操作並且通過過程參數的concat（）進行的。
