通过同义词获取同义词对应表的列名和列的类型



String sql = "select * from " + synonymsName + " where 1!=1";
   rs = sm.executeQuery(sql);
   ResultSetMetaData md = rs.getMetaData();
   for (int i = 1; i <= md.getColumnCount(); i++) {
    map.put(md.getColumnName(i), md.getColumnTypeName(i));//md.getColumnName(i)是列名， md.getColumnTypeName(i)是列的类型
   }
