Question

Delphi 7 :: Connect to SQL 2005 Express BD

Asked by: Marius0188

Dear Experts,

I am in a hurry to get a prototype app up and running and therefore this question:

In SQL 2005 Express I have created a demo database with a test table.
As a result I have a .sdf database file (streaming file).
1. Using Delphi 7 how do I connect to this db file locally?
2. Please also explain how one connect to such db file over a LAN?
    Also explain what the SQL 2005 Express setup should look like on the client (if needed at all) and the
    server.

Example code most welcome.

Thanks in advance.

You should be able to set up a dbExpress connection to the file directly using the drivers installed by SQL 2005 Express.  The file location is one of the parameters of the connection string, which will accept UNC / mapped drive locations.  SQL Server 2005 express needs to be installed (at least client connectivity), just install and accept all defaults in the wizard.

I am using SQL Server 2005 express locally on many machines.  I set up a server on that machine and then use ADO components to connect to it.  By using the server it becomes a trivial matter to connect to it while it is running on a different machine (specify the machine name in your connection string).  I can see that it has created an MDF file, but that knowledge is not needed when connecting to a local server.  If you want to set up the local server, or need more info on how to connect to one, let me know.

Are you writing for a WinCE device?

Usually a .sdf file is used on the WinCE device. Even it could be connected via UNC i.e. \\computername\directory\my.sdf even within the WinCE device, if on a local LAN. However, I know of nothing that will open an .sdf file directly.

Is your MS SQL going to be a local server on each client or are you going to place it on a central server. Makes a difference as to how clients are set up.

sdf files are for SSM, but I thought SSExpress also has the drivers for SDF files (much like it has for Access (.mdb) databases).  As long as the data access drivers are present and registered with the system (install SSM if SSE doesn't do it) then Delphi 7 ADO connection setup dialog will present that driver as a choice, with further configuration to follow in wizard style.

Ok, I got this one solved.
