I just encountered this and my workaround (it is really nasty) was to create an if statement with a condition that will never be true at the top of the stored procedure which selects the same list of outputs as the query with explicit casting to the datatypes I want to return. This will assume nullability of your types, so to resolve that you wrap the cast in an ISNULL
For example, if your output has the columns:
UserId (int, not null)
RoleId (int, nullable)
FirstName (varchar(255), nullable)
Created (datetime, not null)
You would expect this to create a POCO like:
SomeClass {
public int UserId { get; set; }
public int? RoleId { get; set; }
public string FirstName { get; set; }
public DateTime Created { get; set; }
}
...But it doesn't and that's why we're here today. To get around this not working as expected, I put the following at the top of my SP (right after the 'AS'):
if(1=0)
begin
select
UserId = isnull((cast(0 as int)),0),
RoleId = cast(0 as int),
FirstName = cast(0 as varchar),
DateTime = isnull((cast(0 as datetime)),'')
end
It is horrible and ugly but it works for me every time. Hopefully we get a tooling update that resolves this soon...happened to me today with no temp tables in SQL Server 2016 w/VS2015...
Hope this helps somebody
