Delphi + ADO + dBase – Stack Overflow

Posted by jpluimers on 2013/04/10

For my research queue:

I should look at the below ConnectionStrings to access dBase with ADO from Delphi, If I ever need to do that.

Thanks Cromulent for asking, Nelson for editing and Pieter for answering:

Microsoft dBase ODBC driver

Driver={Microsoft dBASE Driver (*.dbf)};DriverID=277;OLE DB Services = -1;Extended Properties=dBase IV;Dbq=c:\mypath

doing operations like ADOTable1.Open are very fast (good) but GetIndexNames returns nothing (bad).

Microsoft Jet OLEDB 4.0 driver

Provider=Microsoft.Jet.OLEDB.4.0;Extended Properties=dBASE IV;OLE DB Services=-1;Data Source=c:\mypath

doing operations like ADOTable1.Open are exceedingly slow (bad) while GetIndexNames does return index names the way it should (good).

How do I get both speed and the index info via ADO for the dBase tables?

Microsoft Paradox Driver 7.x

“We use the following connection string which works really well.”

Provider=MSDASQL.1;Persist Security Info=False;Extended Properties="Driver={Microsoft Visual FoxPro Driver};UID=;SourceDB=c:\mypath;SourceType=DBF;Exclusive=No;BackgroundFetch=Yes;Collate=Machine;Null=Yes;Deleted=Yes;"

    for dBase allways take ApolloDB from vista

    Stop… back away from the ADO. It can work, but it is slow, buggy and there are no updates for it. There are several free alternatives like TDBF. Not sure they work with the latest dbase but are probably better than anything in the ADO.

    There is a caveat.

    In some circumstances the Microsoft drivers need an installed BDE.
