修改失败
其中原来的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 = ?";
我的问题在于:是因为有两个set在sql里面,一般而言有占位符的,使用输出语句的时候,占位符还是原样输出的.
备注:
1.上面的问题也可能是因为使用了oracle的关键字导致
2.如果还是不行,建议直接用加号将赋值的数据直接串联上,而不是使用占位符
