There is no need for this, nor is there any desire, unless you intend to run that same query many times.&lt;/p&gt;
&lt;p&gt;SQL provides regular select statements, prepared select statements, and stored procedures for a reason. &amp;nbsp;Linq now has analogs.&lt;/p&gt;

&lt;p&gt;Have to admit that I've been waiting for your post to arrive in the previous days. The wait was well worth it :-)&lt;/p&gt;
&lt;p&gt;Even 53% is a great number for non-compiled queries. Can't wait to beta 2 ..&lt;/p&gt;

&lt;p&gt;THere's been some talk about having a DataBase as an entire layer in a solution. Using LINQ/DLINQ to &amp;nbsp;build all the queries etc.&lt;/p&gt;
&lt;p&gt;It seems that it can be done, but one thing that strikes me is the performance of this:&lt;/p&gt;
&lt;p&gt;You call one StoredProcedure with an Update, that stored procedure then calls 4 other stored procedures, and on this update you will get 8 result sets back.&lt;/p&gt;
&lt;p&gt;Using DLINQ I would assume you'd have to do multiple DLINQ statements to do the same functionality. &amp;nbsp;Is that correct?&lt;/p&gt;
&lt;p&gt;Thanks :)&lt;/p&gt;
