java - 插入给问题

Question

我做了一个简单的 insert into 语句，但效果不佳。它给我的错误是

com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'From, To, Message, Date, Read) VALUES (3,1,'iepa','2012-10-16 16:26:42',0)' at line 1

这是我的sql代码。

   Connection conn = Connect.getConnection();
            try{
                Statement stmt = conn.createStatement();
                String sql = "INSERT INTO MESSAGE("
                        + "From,"
                        + "To,"
                        + "Message,"
                        + "Date,"
                        + "Read) "
                        + "VALUES(?,?,?,?,?)";
                PreparedStatement pstat = conn.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS);
                pstat.setInt(1, user.getId());
                pstat.setInt(2, Integer.parseInt(who.getText().toString()));
                pstat.setString(3, message.toString());
                pstat.setTimestamp(4, new Timestamp(new Date().getTime()));
                pstat.setInt(5, 0);
                pstat.executeUpdate();

如你所见，我并没有做任何奇怪或困难的事情，但我无法运行它。

你需要转义reserved words in MySQL像带有反引号的 from

String sql = "INSERT INTO MESSAGE("
               + "`From`,"
               + "`To`,"
               + "Message,"
               + "Date,"
               + "`Read`) "
               + "VALUES(?,?,?,?,?)";
