Xamarin studio entity framework5/1/2023 ![]() The first method is a bit of hack in my opinion, but it works. I have found two methods to work with scalar-valued functions. Unfortunately, in my experience, working scalar-valued functions in Entity Framework is still not as easy as tables, views, and stored procedures. We can also call the scalar-valued functions directly. Each function takes a single input parameter, ‘personId’, and returns an integer value – the count of Meals, Activities, and Hydrations for a that Person, based on their Id. These three happen to be the three functions we imported into the EDM. If you view the sql code for the above stored procedure, ‘GetPersonSummary’, you will note it calls three scalar-valued functions. ![]() Included with the downloadable code is a third sql script that should create the User, Role, Login, and required Permissions, if you choose to use them to follow along with the post.įunction Import – Stored Procedure Scalar Functions You can use your own credentials if you choose. DemoRole has the minimal required database permissions the Entity will need to function: Alter, Insert, Delete, Execute, Select, Update, and View definition. I will use the DemoLogin account to connect the EDM to the database. DemoUser is a member of the Database Role, DemoRole. The Database User, DemoUser, is associated with the Login, DemoLogin. In addition, if you are planning to deploy the database and the DAL to other environments such as Test or Production, don’t tie your Solution to personal credentials, a machine-specific account, or to an administrative role in the database with overly broad permissions. However, it is good to get into the habit of securing your database, using database Logins, Users, Roles, and Permissions. This step is not necessary for this post.
