您明确指出:SQLException
您需要指定 为 或 。Statement.RETURN_GENERATED_KEYS
Statement.executeUpdate()
Connection.prepareStatement()
这可以按如下方式实现(在方法上添加附加值):Connection.prepareStatement()
String SQL = ""; //whatever my String is
PreparedStatement ps = connection.prepareStatement(SQL, Statement.RETURN_GENERATED_KEYS);
ps.setString(1, "value");
//Other necessary ps.setXXX() methods
//now update
ps.executeUpdate();
ResultSet rs = ps.getGeneratedKeys();
这是关键。Statement.RETURN_GENERATED_KEYS
希望这有帮助!
PS:有用的资源。
@Charlie伯格,因为你更喜欢懒惰,我改变了你的代码的第13行,包括:Statement.RETURN_GENERATED_KEYS
ps = con.prepareStatement("INSERT INTO characters (level, fame, str, dex, luk, `int`, exp, hp, mp, maxhp, maxmp, sp, ap, gm, skincolor, gender, job, hair, face, map, meso, hpMpUsed, spawnpoint, party, buddyCapacity, messengerid, messengerposition, mountlevel, mounttiredness, mountexp, equipslots, useslots, setupslots, etcslots, monsterbookcover, watchedcygnusintro, vanquisherStage, dojopoints, lastDojoStage, finishedDojoTutorial, vanquisherKills, matchcardwins, matchcardlosses, matchcardties, omokwins, omoklosses, omokties, givenRiceCakes, partyquestitems, jailtime, accountid, name, world) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)", Statement.RETURN_GENERATED_KEYS);
此外,类是包(确保正确导入)。:-)Statement
