How to: Query for Information

Queries in [!INCLUDEvbtecdlinq] use the same syntax as queries in [!INCLUDEvbteclinq]. The only difference is that the objects referenced in [!INCLUDEvbtecdlinq] queries are mapped to elements in a database. For more information, see Introduction to LINQ Queries (C#).

[!INCLUDEvbtecdlinq] translates the queries you write into equivalent SQL queries and sends them to the server for processing.

Some features of [!INCLUDEvbteclinq] queries might need special attention in [!INCLUDEvbtecdlinq] applications. For more information, see Query Concepts.

Example

The following query asks for a list of customers from London. In this example, Customers is a table in the Northwind sample database.
