It’s not as nice as using a tool like Linq, but there is another option. Look into SQL Linked Servers. You can link an SQL server to DB2 and then connect and run queries through SQL. This should allow you to use Linq with DB2.

In the Machine class above, there may be another attribute you need to put on the primary key field (PLCID) to signify that it is an autonumber. Just by marking it as primary key it would think it must be required on inserts. In the case above, the PLCID would be a value I would want to set when inserting the record.

If you’re using MS Access, you should be able to use Linq to talk directly to it. The Toolkit is really for creating providers to non-Microsoft databases (if one doesn’t already exist) that can talk to Linq.

Check out C# when you get a chance. I much prefer it to VB, although I’ve spent many years with PHP so that may be why.

Is there a way to use IQToolkit to insert, update and delete?

I tried to make this on my own but experiencing some problems:
1) I made a code based on yours and i can make it insert in ms access db but, i have to provide a valid key otherwise – get error. Quiet a strange thing when thinking about insert – key must be provided automaticly.
2) I cant delete from db – getting error somhere in depth of IQtoolkit. – i am not familiar with C# to figure it out by myself = (
3) I can`t use “where” in query like Dim machs = From m In db.Machines where m.PLCID=something – get something like “not implemented exeption”. I can query “machs” of course.

A have a feeling that i am doing something wrong but cant figure out what exactly. = )
