delphi通过ado连接sybase12.0数据库,通过adodataset和adoquery连接一表,想读取所有记录,循环读取,得到的总是第一条记录的数据.

while(!ado1->Eob)
{
//处理
ado1->Next();
}

我用的是delphi
while not adotable1.eof do
begin
l1:=adotable1.fields[0].asstring;
l2:=adotable1.fields[1].asstring;
l3:...
adocommand1.prepared;
adocommand1.Parameters.ParamByName('ss').value:=l1;
adocommand1.execute;
adotable1.next;

end;
