我不确定为什么我的代码不起作用。我好近！为什么我的语法出现错误？对我来说看起来正确吗？有人可以帮我吗？任何帮助深表感谢！

在这种情况下，我将使用 PreparedStatement 来简化此代码：

PreparedStatement st;

st = connection.prepareStatement(""
   +"INSERT INTO hiscores (userid, playerRights, LVL, XP, " 
   +"`0`,`1`,`2`,`3`,`4`,`5`,`6`,`7`,`8`,`9`,`10`,`11`,`12`,`13`,`14`,`15`,"
   +"`16`,`17`,`18`,`19`,`20`) "
   +"VALUES(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)";

st.setInt(    1, player.getUniqueId());
st.setString( 2, player.getStaffRights());
st.setInt(    3, player.getSkill().getTotalLevel());
st.setString( 4, player.getSkill().getTotalXp());

for(int i=0; i<=20; i++){
   st.setInt( i+5, player.getSkill().getExp()[i]);
} 

st.executeUpdate();
