数据库指向记录的指针怎么用?

[superhuhao]

例如我要把ADOQuery1->First()或是当前的指针的值赋给我自定义的指针变量,怎么定义这个变量啊?
谢谢!

看看ado和数据库吧,不要把所有的指针都混为一摊

你可以看看这是返回什么类型，你再定义一个就是了

用Bookmark

不明白LZ想做什么,保存当前的数据表指针吗?
参考一下这个

TBookmark SavePlace;
Variant PrevValue;

// get a bookmark so that we can return to the same record

SavePlace = ClientDataSet1->GetBookmark();

ClientDataSet1->FindPrior();// move to prior record

PrevValue = ClientDataSet1->Fields->Fields[0]->Value; // get the value

// Move back to the bookmark

// this may not be the next record anymore
// if something else is changing the dataset asynchronously
ClientDataSet1->GotoBookmark(SavePlace);
ClientDataSet1->Fields->Fields[0]->Value = PrevValue; // set the value
ClientDataSet1->FreeBookmark(SavePlace);
