execute stored proc in ExecuteStoreQuery EF. is this a bug in EF?

Question

trying to execute the stored proc in EF using the following code:

var params = new object[] {new SqlParameter("@FirstName", "Bob")};
return this._repositoryContext.ObjectContext.ExecuteStoreQuery<ResultType>("GetByName", params);

but keep getting this error:

Procedure or function 'GetByName' expects parameter '@FirstName', which was not supplied.

and from sql profiler:

exec sp_executesql N'GetByName',N'@FirstName nvarchar(100),@FirstName=N'Bob'

what is wrong wit the above ExecuteStoreQuery code?

Answer 1

Ignoring the fact that params is a reserved word...

Think your query needs to be:

var params = new object[] {new SqlParameter("@FirstName", "Bob")};
return this._repositoryContext.ObjectContext.ExecuteStoreQuery<ResultType>("exec GetByName @FirstName", params);

Should also say that if that proc is a standard part of your database and data model then you should import it into your EDM so it's available directly on your context.
