This article mainly introduces how LinQ calls stored procedures, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, let the editor take you to understand it.

Let's take a look at some of the basic operations of LinQ in paging and LinQ calls to stored procedures. Of course, the stored procedure to be exemplified is not a stored procedure that retrieves the database by paging.

1. Paging search Article

The code is as follows:

Var pagedArticles = (from s in cntx.Articles where s.CategoryName.ToUpper ()) = "CSHARP" orderby s.PostDate descending select s) .Skip (100) .Take (20)

The above code retrieves 20 rows of records after the 100th of articles of type C # (sorted in descending order of publication time) in the database, which is page 6 if it is calculated according to 20 records per page, in which we use the Skip () and Take () methods.

2.LinQ calls stored procedures

When we created the dbml file above, we dragged a stored procedure (GetParentCategories) into the method box. My main purpose of writing this stored procedure is to get a list of parent types of the current type. Just one line of code, the code is as follows:

Var categories = cntx.GetParentCategories (1); Thank you for reading this article carefully. I hope the article "how to call stored procedures in LinQ" shared by the editor will be helpful to you.
