Batch Insert Update Delete Operations. Entity Framework is a well known Microsoft open source from EF 5 data access technology for. NET applications. Entity Framework is a new framework which completely replaces traditional ADO. NET data access techniques. Entity Framework enables new approaches to work with relational databases. It will reduce line of code that developers uses for data access. This article will briefly describe how to perform batch CRUD operations using entity framework and its extensions. To implement Bulk operation, we need to add some base classes.

A current limitation of the Entity Framework is that in order to update or delete an entity you have to first retrieve it into memory. Also, for single deletes, the object must be retrieved before it can be deleted requiring two calls to the database. To overcome this problem we have to extend the current entity framework using Entity. Framework. Extended. Entity. Framework. Extended have useful features like Batch Update and Delete, Audit log, Query Result cache, Future Queries. Batch update and delete eliminates the need to retrieve and load an entity before modifying it. Here are a few lines of code to demonstrate how to delete, update. Install via nuget. PM Install Package Entity. Framework. Extended. Update. Scenario Update customers which have country USA. If we do this without any extensions, we have to fetch all customers which have country USA, modify the list and update it using loops. Using Entity Framework. Exdended we dont need to fetch the list of customers, simply add where condition, set update data and execute query. Mainstring args        usingvar db  new Data. Context                db. Customers. Wherec  c. Country  USA. Updatec  new Customer                        Country  IN                      foreachvar customer in db. Customers. To. List                         Console. Write. LineCustomer. Info  0 1 2, customer. Name, customer. Country, customer. Status                        Console. Read. Line    Output. All customers Tom and Eric which have country USA will update to IN. Delete. Scenario Delete customers which have country China. Batch update and delete operation are almost same. Add where condition to both Delete and Update call Entity. Framework. Extended function. Mainstring args        usingvar db  new Data. Context                db. Customers. Wherec  c. Country  CHINA.

Status                        Console. Read. Line    Output Two records are deleted having a customer name Chang and Sam. Conclusion. Entity framework is improving day by day. But Entity framework extensions and utilities make developers life easy. They enhances and optimizes Entity Frameworks performance, add more capabilities, add more features and extend current version limitation. Hope Microsoft will include Batch insert, update and delete facility in Entity Framework version.
