关于夸库查询系统表数据

var sql1 = "select * from t_user";
var datas1 = queryByDSName("obpm",sql1);
该查询报错，什么原因：

因为你代码贴的不全...
所以给你例子和说明下!

try{
var sql = "select name,id from t_user where defaultapplication='"+getApplication()+"'";
var datas = queryByDSName("kd",sql);
if(datas!=null){
   for(var iterator = datas.iterator();iterator.hasNext();){
       var map1 = iterator.next();//取值
       var name= map1.get("name");  //自己看字段和select
       var value = map1.get("id");
    }
}
}catch(e){
       
}

或者

sqlserver 夸数据库可以使用 库名.表
oracle 自己百度.
使用我们的queryBySQL函数select  字段必须有domainid字段
var sql="select id,item_SQL电话,'"+getDomainid()+"' as domainid from tlk_查询文档记录SQL where item_SQL姓名='"+user+"'";
var query = queryBySQL(sql);
if(query!=null){
          var iter  =query.iterator();
          if(iter != null && iter.hasNext()){
               doc = iter.next();
               var rtn = doc.getItemValueAsString("SQL电话");   //自己看字段和select
                           var id=doc.getId();
          }
}
}

对于select * 建议  5个字段内取值不要用  *  直接打字段名.
