How to call Stored Procedures with EntityFramework?

Question

I have generated an EF4 Model from a MySQL database and I have included both StoredProcedures and Tables.

I know how to make regular instert/update/fetch/delete oper

Answer 1

This is an example of querying MySQL procedure using Entity Framework

This is the definition of my Stored Procedure in MySQL:

CREATE PROCEDURE GetUpdatedAds (
    IN curChangeTracker BIGINT
    IN PageSize INT
) 
BEGIN
   -- select some recored...
END;

And this is how I query it using Entity Framework:

 var curChangeTracker = new SqlParameter("@curChangeTracker", MySqlDbType.Int64).Value = 0;
 var pageSize = new SqlParameter("@PageSize", (MySqlDbType.Int64)).Value = 100;

 var res = _context.Database.SqlQuery<MyEntityType>($"call GetUpdatedAds({curChangeTracker}, {pageSize})");

Note that I am using C# String Interpolation to build my Query String.
