用C++ Builder更新数据库内容，提示ADOQuery1：missing SQL property
ADOQuery1->SQL->Text="Select * from dbo.goods where gnum= '" + Edit1->Text + "' ";
ADOQuery1->ExecSQL();
ADOQuery1->Active=true;
String strSQL="";
ADOQuery1->SQL->Text=strSQL;
if(Edit1->Text == ADOQuery1->Fields->FieldByName("gnum")->AsInteger)
{
strSQL="Update dbo.goods set gcount = gcount + Edit2->Text";
}

运行后，提示adoquery1.active:=ture时，提示“adoquery1:missing sql property”

这是什么问题呢？新手求助！
[解决办法]

注释掉ADOQuery1->ExecSQL();
ADOQuery1->SQL->Text="Select * from dbo.goods where gnum= '" + Edit1->Text + "' ";
ADOQuery1->Active=true;
