[AccessD] SQL against recordset

Hi Mark

Did you read the post from Shamil:

"The Baker's Dozen: A 13-Step Crash Course for Using LINQ":

<quote>

LINQ is a set of extensions to the .NET Framework to query different types of data using a common language. Orcas Beta 1 features the following LINQ capabilities within .NET:

Querying Microsoft SQL Server data using a strongly-typed DataContext (LINQ to SQL) 
Querying in-memory .NET objects (LINQ to Objects) 
Querying .NET DataSets (LINQ to DataSets) 
Querying XML Data (LINQ to XML) 

</quote>

Using LINQ with a DataSet might be faster than your current solution.

The Recordset was retrieved from the (local) Access database...and as a 
snapshot, it was only twice as slow...so far...unless I'm doing something 
way off here...running 10K SQL statements seems to be fastest...but I'm 
having a hard time accepting that.

Thanks,
