Hi There,

I’m taking it this solution does not work with Visual Studio 2003? Is there a solution that will work in my case?

Any help will be appreciated!

Thanks
Mishal

That is a tricky one, Fernando, but here is a thought:
Create a new datatable/data adapter in the data designer that contains the data you want from tables 2 and 3, and link it to table 1. Then bind the datagrid to this new datatable.

Relationship(One Client Many Orders; One Order Many Products)

table1(ClientTable) has ClientId , FName and LastName fields

table2(OrderTable) has OrderId,ClientID,ProductId,Date,Quantity

table3(ProductTable) has ProductId,Description,Price

There will be a form showing table one in form style and tables 2 and 3 in a datagrid (table one is bound to table 2+3)

showing the only the following fields:

I am specially concerned about the bound datagrid with tables 2+3

I am able to bind only two tables with one form and one data grid(with one table)

How do i bind table one to tables 3+2) I want to show one grid for table 2+3 as follows:

Quantity(t2) Description(t3) Price(t3) ExtendedPrice(added)

Jeff,

Thanks for the compliment.

I have considered SQL Server Express. It is robust and FREE – and a good fit for development environments, or maybe even single-user database applications. However, I’ve read plenty of comments about how it really isn’t suitable for production environments due to its size limit (4GB – plenty obviously – but what if you need more?).

My focus (other than learning this stuff) is my company (emGee Software Solutions – http://www.emgeesoft.com). My partner and I designed a few multi-user database applications, and took into consideration future requirements of our customers. Obviously, this conversation can take many tracks with room for agreement and disagreement. But from our POV, MySQL offered the best path for a low-cost multi-user database solution with room for future growth.

My first guess is that there is a problem with your INSERT statement. Since UPDATE and DELETE are working, the TableAdapter is working. Are you receiving an error message?

Thank you Mathew for an informative tutorial.

I am an experienced programmer, but that doesn’t help when you are using arbitrarily arranged wizards like in VS2005! One note: if you enter ? marks in the New Value columns (for assign), and Filter (for the where clause) the wizard will generate the SQL statements for you. Just a little short cut.

Also, MS has published SQL Server 2005 express for free. It seems like a very robust version and will serve many people’s needs quite well.

And its FREE. That might help with some of the data concurrency issues (Not sure if it will solve all the issues, as I haven’t got that far in my first VS project).

Thanks again

Jeff

Kenan,

I’m not sure what the error is. Perhaps you are using a newer version of MySQL ODBC Connector that has a different screen? Or maybe you need to re-install it?

The step 4 you are at is optional, however. You do not have to create a DSN to make it work. Instead, you can create a Connection String, which is described later in the tutorial.
