Customizing Operations: Overview

By default, LINQ to SQL generates dynamic SQL for insert, update, and delete operations based on mapping. However, in practice you typically want to add your own business logic to provide for security, validation, and so forth.

LINQ to SQL techniques for customizing these operations include the following.

Loading Options

In your queries, you can control how much data related to your main target is retrieved when you connect to the database. This functionality is implemented largely by using DataLoadOptions. For more information, see Deferred versus Immediate Loading.

Partial Methods

In its default mapping, LINQ to SQL provides partial methods to help you implement your business logic. For more information, see Adding Business Logic By Using Partial Methods.

Stored Procedures and User-Defined Functions

LINQ to SQL supports the use of stored procedures and user-defined functions. Stored procedures are frequently used to customize operations. For more information, see Stored Procedures.
