ADOQuery取SQLSERVER数据的numeric问题
数据库中partcode cardtype是varchar类型
processid cardno是numeric类型

我的代码是这样的

ADOQuery2-> Close();
ADOQuery2-> SQL-> Clear();
ADOQuery2-> SQL-> Add( "select partcode, cardtype, processid, cardno "
"from processcard_head "
"where partcode = ' " + strPara + " ' ");
ADOQuery2-> Open();

while(!ADOQuery2-> Eof)
{
strPartCode = ADOQuery2-> FieldByName( "partcode ")-> AsString;
strReturn = strReturn + strPartCode + "@# ";
strCardType2 = ADOQuery2-> FieldByName( "cardtype ")-> AsString;
strReturn = strReturn + strCardType2 + "@# ";
strProcessid = ADOQuery2-> FieldByName( "processid ")-> AsString;
strReturn = strReturn + strProcessid + "@# ";
strCardno = ADOQuery2-> FieldByName( "cardno ")-> AsString;
strReturn = strReturn + strCardno + "@# ";
ADOQuery2-> Next();
}

现在的问题是数据中对应的processid cardno的值分别是是-7和-1,代码中strProcessid和strCardno的值分钟是7和1,请高手帮忙怎么解决?
