Using SqlQuery in Entity Framework

Question:

Tag: sql-server,entity-framework

Is this really true that order of sql parameters in sql stored procedure must match the order of sql parameters used in SqlSquery:

 var Parameter = new List<SqlParameter>();
 Parameter.Add(new SqlParameter("@ParamOne", 1));
 Parameter.Add(new SqlParameter("@ParamTwo", 2));
 Parameter.Add(new SqlParameter("@ParamThree", 3));

context.Database.SqlQuery<myEntityType>("exec sp_Stored_Procedure @ParamOne, @ParamTwo, @ParamThree", Parameter.ToArray()).ToList<myEntityType>();

And in case sql developer decides to change stored procedure in the following way

ALTER PROCEDURE [dbo].[sp_Stored_Procedure]
@ParamOne as int,
@ParamTwo as int,
@ParamThree as int, 

AS ......

the result set will be empty?

This could raise many issues and I am asking is there something I am missing in this scenario?


Answer:

I was oblivious to the situation at first!

Something like this should resolve your issue:

 var Parameter = new List<SqlParameter>();
 Parameter.Add(new SqlParameter("@p1", 1));
 Parameter.Add(new SqlParameter("@p2", 2));
 Parameter.Add(new SqlParameter("@p3", 3));

context.Database.SqlQuery<myEntityType>("exec sp_Stored_Procedure @ParamOne = @p1, @ParamTwo = @p2, @ParamThree = @p3", Parameter.ToArray()).ToList<myEntityType>();
