添加,编辑,删除 记录

[cathy_sui_lyell]

我知道是添加删除和编辑记录
但是具体要怎么用呢?

[huzhangyou]

The following example copies the data in the Notes field of Table1 to the Remarks field of ClientDataSet1.

void __fastcall TForm1::Button1Click(TObject *Sender)

{
TBlobStream *Stream1;
TStream *Stream2;

Stream1 = new TBlobStream(Table1Notes, bmRead);
try
{
ClientDataSet1->Edit();
// here抯 another way to create a blob stream
Stream2 = ClientDataSet1->CreateBlobStream(ClientDataSet1->FieldByName("Remarks"), bmReadWrite);
try
{
Stream2->CopyFrom(Stream1, Stream1->Size);
ClientDataSet1->Post();
}
__finally
{

delete Stream2;
}
}
__finally
{
delete Stream1;
}
}

我是直接这样用的：
1、Delete
ADOQuery1->SQL->Clear();
ADOQuery1->Add("查询你要删的记录");
ADOQuery1->Open();
ADOQuery1->Delete();
2、Edit
ADOQuery1->SQL->Clear();
ADOQuery1->Add("查询你要修改的记录");
ADOQuery1->Open();
ADOQuery1->Edit();
ADOQuery1->FieldByName("要改变当前行的列名")->AsString="你想要存的值";
ADOQuery1->Post();//存入数据库
3、Append
ADOQuery1->SQL->Clear();
ADOQuery1->Add("查询你要在哪个表中增加记录的表");
ADOQuery1->Open();
ADOQuery1->Append();
ADOQuery1->FieldByName("新增记录的指定列")->AsString=Value;
ADOQuery1->Post();//存入数据库
如有不对之处请指教,如果对了请多给点分就OK了
