app srv 上不装 BDE
除了D5的ADO
 
To provide data from and apply updates to a dataset that is not
BDE-enabled, use TDataSetProvider instead.
 
另: 我的盘好了吗?
 
//faint
这句话说明什么呢?那玩意是D5推荐的东西
 
说明不要用 TProvider, 用TDataSetProvider呗(如果不通过bde的话)
 
appserver不用bde?那怎么访问数据库?
 
yifeng:用ODBC/ADO
eYes:由于我的机器不在手上,所以没有DELPHI,也不能实验,只有一个D5 PREVIEW
那东西上只有DATASETPROVIDER:-)
 
Unlike the TProvider component, which can apply updates directly to a remote database server, TDataSetProvider applies updates to a dataset component in the same application. When working with BDE-enabled datasets, this creates an unnecessary step, because the dataset must then apply the updates to the remote database server. However, by using TDataSetProvider, you can apply updates to other datasets (client datasets or custom components derived from TDataset).

TDataSetProvider has no dependencies on the Borland Database Engine. Applications built using TDataSetProvider and client datasets or custom dataset do not need to include the BDE when they are deployed.

 
我说了,现在没有DELPHI,试完了就给分
 
后退
