Java Prepared Statement 连接 hive 服务器以描述表的语法

如何解决Java Prepared Statement 连接 hive 服务器以描述表的语法

尝试建立与 hive 的连接并描述一个表。

enter code here
    String queryTable= "dummydb.dummy_table";
    String driverName = "org.apache.hive.jdbc.HiveDriver";
    try {
        Class.forName(driverName);
    } catch (ClassNotFoundException ex) {
        ex.printstacktrace();
    }
    //connect hive server (no issue in that)
    String hiveUrl = PropertyLoader.getInstance("staging").getDruidHive();
    Connection con = DriverManager.getConnection(hiveUrl,"hadoop","");

    ##Working code is below:
         String sql = "describe formatted dummydb.dummy_table" ;
         PreparedStatement pstmt = con.prepareStatement(sql);
         ResultSet rs1 = pstmt.executeQuery();

    ##But I try to use this which is not working:

        String queryTable="dummydb.dummy_table"
        String sql1 = "describe formatted ?" ;
        PreparedStatement pstmt = con.prepareStatement(sql1);
        pstmt.setString(1,queryTable);
        ResultSet rs1 = pstmt.executeQuery();

错误 org.apache.hive.service.cli.HivesqlException：编译语句时出错：Failed：ParseException 行 1:19 无法识别描述语句中'格式化'''dummydb.dummy_table''''附近的输入
