Linq to Sql handles every insert/delete/update operation on an object with separate query. Is there a way to unite multiple operations in single query?
I know this is not possible with the default behavior of the framework. I’m looking for an extension method or workaround. I want to use the queries generated by Linq to Sql, not my own queries or stored procedures but unite multiple operations in a single round-trip to the database.
look at this post : How to run a mass update/delete query in Linq?
It’s a link to how to implement a batch update, batch delete … hope it helps
