修改失敗
其中原來的sql是:
String updatesql = "update WaterSoilConservation set wsc_name = ? " +
",set wsc_checktime = ? ,wsc_checkcontext = ?,wsc_checkmethod = ?" +
" ,wsc_mainresult = ? ,wsc_sendconpany = ?,wsc_docompany = ?,wsc_watchcompany = ? where wsc_id = ?";
我的問題在於:是因爲有兩個set在sql裏面,一般而言有佔位符的,使用輸出語句的時候,佔位符還是原樣輸出的.
備註:
1.上面的問題也可能是因爲使用了oracle的關鍵字導致
2.如果還是不行,建議直接用加號將賦值的數據直接串聯上,而不是使用佔位符
