Batch Updates and Deletes with LINQ to SQL
submitted by terry.aney 5 months, 26 days ago

aneyfamily.com — A couple weeks ago, I read the article, LINQ to SQL Extension: Batch Deletion with Lambda Expression by Jeffrey Zhao. In case you didn't read the article, it discusses the downside of most O/R Mapping frameworks when it comes to multiple updates or deletes. He states the fact that a SQL statement for each row flagged as update/delete in the entity set is created. I went about implementing something similar to what Jeffrey envisioned and I'll explain some of the hurdles I had to overcome to achieve it.
