c++ builder两个ADOQuery如何关联？ ( 积分: 30 )

急急！！！！！
后天就要交程序给使用单位，现在还有问题没解决？
两个ADOQuery关联 用BDGRID显示查询结果，从表显示不出来
程序如下
AnsiString sSql;
sSql="select * frrom Table_Test2_Quality";
F_Query->DBGrid_Test_Quality->DataSource=DataMod->DataSource_Test2_Quality;
if(DataMod->ADOQuery_Test2_Quality->Active==true)
DataMod->ADOQuery_Test2_Quality->Close();
DataMod->ADOQuery_Test2_Quality->SQL->Clear();
try
{
DataMod->ADOQuery_Test2_Quality->SQL->Add(sSql);
DataMod->ADOQuery_Test2_Quality->Open();
}
catch(...)
{
ShowMessage("操作数据库有误! ");
return;
}

sSql="select * frrom Table_Test2 where Table_Test2.Quality_ID=:Quality_ID";
F_Query->DBGrid_Test->DataSource=DataMod->DataSource_Test2;
if(DataMod->ADOQuery_Test2->Active==true)
DataMod->ADOQuery_Test2->Close();
DataMod->ADOQuery_Test2->SQL->Clear();
try
{
DataMod->ADOQuery_Test2->SQL->Add(sSql);
DataMod->ADOQuery_Test2->Open();
}

{
DataMod->ADOQuery_Test2->SQL->Add(sSql);
DataMod->ADOQuery_Test2->Open();
}

DOQuery1->DataSource1
DOQuery2->DataSource2
DOQuery1.DataSource := DataSource2;

应是这样吧
ADOQuery1->DataSource1
ADOQuery2->DataSource2
ADOQuery2.DataSource = DataSource1；

急！！！在线等待

要用datasource结合AQOQUERY的参数传递

就没人知道我错在哪里吗

大问题我自己解决了，只是还有小问题，关联字段（Quality_ID）在主表中不能用中文显示（'综合值系号'=Quality_ID），用中文显示就不能产生关联，是为什么？

谢谢
