Question

I have a column of type Bit (called BBoolVal in this example).

I have a LinqToSQL Statement Like this:

var query = List<MyClass> myList = _ctx.DBList
              .Where(x => x.AGuidID == paramID) 
              .Where(x => x.BBoolVal == false);

When I look at the sql it ends up like this (I added the spacing and changed the names):

SELECT    [t0].[Id], [t0].[AGuidID], [t0].[OtherIDID], 
          [t0].[TimeColumn], [t0].[BBoolVal], [t0].[MoreID]
FROM      [dbo].[MyTable] AS [t0]
WHERE (NOT ([t0].[BBoolVal] = 1)) AND ([t0].[AGuidID] = @p0)

Because my x.BBoolVal == false translates to [BBoolVal] == 1 I gather that false = 1 (and thus true = 0).

I am asking because this seems a bit backwards to me. I am fine to accept it, I just want to be sure.

Answer 1

Notice it says WHERE (NOT ([t0].[BBoolVal] = 1)) AND ([t0].[AGuidID] = @p0)

While is is really odd that it did that, it is effectively the same as [t0].[BBoolVal] = 0

EDIT

Giving it some thought, this way BBoolVal will match on False or NULL (assuming that BBoolVal is nullable).
