How Can I Call Stored Procedures in Entity Framework 6 (Code-First)?

Entity Framework 6 Code-FIRST method calls the storage procedure

Entity Framework 6 provides a mechanism that allows the storage procedure in Code-FIRST applications. This is very useful when you need to use the existing storage procedures with the EF model, or to create your own storage procedure for specific operations.

Call the storage procedure

In the Entity Framework 6, you can use the method on the DBCONTEXT class.

Method accepts two parameters: the name of the storage procedure to be called and the parameter array passed to the stored procedure.

SqlQuery For example, the following code calls SqlQuery Storage procedures and pass

parameters to it:

insert_department Name Back multiple results sets

<code class="language-csharp">this.Database.SqlQuery<int>("insert_department", new SqlParameter("@Name", departmentName));</code>
Copy after login

Some storage procedures return multiple results sets. If you need to access the results of each result set, you can use the method. Method Returns a

, which contains the results of the results of each result set.

ExecuteSqlQuery For example, the following code calls ExecuteSqlQuery Storage procedures and retrieve the results in the ObjectResult object list:

get_departments Other descriptions Department

<code class="language-csharp">var departments = this.Database.ExecuteSqlQuery<Department>("get_departments");</code>
Copy after login

If the storage procedure returns the scalar value, you can use the method to retrieve the value.

If the storage procedure has output parameters, you can use the
    method to call the storage procedure and retrieve the output parameter.

  • and
  • methods to call the corresponding storage procedures. ExecuteStoredProcedure
