I have two DataTables with a foreign key between them and I can query each
DataTable and combine data. Is there an easy way for me to make a query against the two, just like the join query in SQL Server against two tables? Or what is the best way to do it? I check on DataView and DataSet class and won't let me do it. |

Hi Roy,
The easiest way is to do it on the server (as you mentioned - with joins) as there is no join support in ado.net (you can still do it manually). -- Miha Markic [MVP C#] RightHand .NET consulting & development www.rthand.com Blog: http://cs.rthand.com/blogs/blog_with_righthand/ "Roy" <Roy@discussions.microsoft.com> wrote in message news:05528EC4-E3A7-4ED9-994E-84E59DEA2432@microsoft.com... >I have two DataTables with a foreign key between them and I can query each > DataTable and combine data. > Is there an easy way for me to make a query against the two, just like the > join query in SQL Server against two tables? > Or what is the best way to do it?

Roy,
You might be interested in the assembly I've been working on at http://www.queryadataset.com. Besides INNER JOINS, it lets you perform complex SQL SELECT statements including UNION, OUTER JOINS, GROUP BY, HAVING, ORDER BY, sub-queries, etc against the tables in a dataset. It might be overkill for what you want, but it might be a useful tool too.
