Start Updating a row in linq to sql

Updating a row in linq to sql

This tutorial covers how to use Entity Framework, Language Integrated Query (LINQ), and generate Data Definition Language (DDL) scripts using Model-First for Oracle database. Next, Visual Studio can create Oracle DDL scripts to generate the relational database model based on the conceptual model. You will start by creating an Entity Data Model (EDM) from an existing Oracle Database schema using Entity Data Model Wizard.

You will then create the code to execute a LINQ query and return the results to the console window. The code executes a LINQ query against the EDM you just created.

Type the namespace references highlighted in the graphic below. It then accesses the result and outputs it to the screen.

In the next section, you will query these same rows to demonstrate the salaries have indeed been set to 18010.

In this section, you will define your own method that is mapped to an Oracle stored procedure, which performs an update.

Click (Start Debugging) to view the updated results with the salaries increased by 10.

Note: Press Enter twice to continue while viewing the output.

In the Solution Explorer window, select and click Model Browser.
