ibatis中寫SQL語句時使用in遇到的問題描述

update chunqiu3.order_head t set t.status = #flag# where t.id in (#orderids#)

傳遞的id為2488877,2488878,2488879。但是資料卻沒有任何的修改。

因為ibatis缺省會把「#」中間的變數作為字串來處理。這樣，就會出現這樣的sql

update chunqiu3.order_head t set t.status = 1 where t.id in ('2488877,2488878,2488879')

update chunqiu3.order_head t set t.status = $flag$ where t.id in ($orderids$)

update chunqiu3.order_head t set t.status = 1 where t.id in (2488877,2488878,2488879)
