我是用JSP想插入数据到SQL里!

[sound9world]

无代码 无真相啊

或者猜测说 是不是没有用内置对象out

[h641695]

刚刚看了一下! 说是插入日期的问题!

SimpleDateFormat HFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
String strCurrenTime = HFormat.format(new Date());
con = ConnectionHelp.getConnection();
String strSql = "insert into FirstLevelTitle values(?,?,?,?)";
ps = con.prepareStatement(strSql);
ps.setInt(1, getNewId());
ps.setString(2, fTitle.getTitleName());
ps.setString(3, fTitle.getCreator());
ps.setString(4, strCurrenTime);

sql 语句争取要写全，insert into tab(列名，列名。。) values(?,?..)

[crazylaa]

ps.setString(4, strCurrenTime);

什么数据库？用数据库时间作为系统时间好了。

mysql：
String strSql = "insert into FirstLevelTitle values(?,?,?,now())";
oracle:
String strSql = "insert into FirstLevelTitle values(?,?,?,systimestamp)";
然后删掉ps.setString(4, strCurrenTime);

[h641695]

还是不行! 插入不进去!
