实在不行，估计得更新驱动到VFP8/VFP9
goos9005mlgk 2008-01-25
MyModule->ADOConnection1->Close();
MyModule->ADOConnection1->ConnectionString = "Driver=Microsoft Visual FoxPro Driver;SourceType=DBF;SourceDB=" + DataPath + ";Exclusive=No";
MyModule->ADOConnection1->Open();
MyModule->ADOQuery1->Close();
MyModule->ADOQuery1->Connection = MyModule->ADOConnection1;
MyModule->ADOQuery1->SQL->Clear();
MyModule->ADOQuery1->SQL->Add("select * from mydb.dbf into dbf newdb.dbf")
MyModule->ADOQuery1->ExecSQL();
MyModule->ADOQuery1->Close();
MyModule->ADOConnection1->Close();
不报错，但没任何结果

我已经说过了，首先确定你的驱动对不对。

回楼上的大侠，用 select * from mydb.dbf into dbf newdb.dbf在BCB里面不报错，但什么也没有做

一段代码仅供参考：
if (DM->qryLog->RecordCount <= 0)
{
Application->MessageBoxA("表里没有数据！","提示",MB_OK);
return;
}
AnsiString filter = svdlg->Filter,FileDir,filename,tablename;
svdlg->Filter = "DBF 文件(*.Dbf)|*.Dbf";
if(svdlg->Execute() == IDOK)
{
filename = ChangeFileExt(svdlg->FileName,".Dbf");
if (FileExists(filename))
{
if (MessageBox(NULL,"是否覆盖该文件？","消息",MB_YESNO) == IDNO)
return;
else
DeleteFile(filename);
}
filename = ExtractFileName(filename);
AnsiString ffile = ExtractFilePath(Application->ExeName ) + "_Part.dbf";
if (!CopyFile(ffile.c_str(),filename.c_str(),false))
{
Application->MessageBoxA("创建文件失败！","警告",MB_OK);
return;
}
FileDir = ExtractFileDir(svdlg->FileName);
try
{
DM->tblVideo->Close();
DM->tblVideo->DatabaseName = FileDir;
DM->tblVideo->TableName = filename;
DM->tblVideo->Open();
DM->qryLog->First();
for(int i = 0;i < DM->qryLog->RecordCount; i++)
{
DM->tblVideo->Append();
for(int j = 0;j < 12; j++)
//for(int j = 0;j < DM->qryLog->Fields->Count; j++)
{
DM->tblVideo->FieldValues[DM->tblVideo->Fields->Fields[j]->FieldName]
= DM->qryLog->FieldValues[DM->qryLog->Fields->Fields[j]->FieldName];
Application->ProcessMessages();
}
DM->tblVideo->Post();
DM->qryLog->Next();
}
Application->MessageBoxA("导出DBF成功！","提示",MB_OK);
}
catch(...)
{
Application->MessageBoxA("数据库连接错误!", "错误", MB_OK);
}
}
DM->tblVideo->Close();
svdlg->Filter = filter;
if (DM->qryLog->RecordCount <= 0)
{
Application->MessageBoxA("表里没有数据！","提示",MB_OK);
return;
}
AnsiString filter = svdlg->Filter,FileDir,filename,tablename;
svdlg->Filter = "DBF 文件(*.Dbf)|*.Dbf";

DM->tblVideo->Open();
DM->qryLog->First();
for(int i = 0;i < DM->qryLog->RecordCount; i++)
{
DM->tblVideo->Append();

DBF？如果是使用VFP的驱动，可以直接select .... into NewTable.
