	let date = bid.DateTime.AddHours(7)
	where date.Year == Year && date.Month == Month
	select bid;

exec sp_executesql N'SELECT [bid].[Id], [bid].[Comment], [bid].[DateTime]
FROM [Bids] AS [bid]
WHERE (DATEPART(year, DATEADD(hour, 7E0, [bid].[DateTime])) = @__Year_0) AND (DATEPART(month, DATEADD(hour, 7E0, [bid].[DateTime])) = @__Month_1)',N'@__Year_0 int,@__Month_1 int',@__Year_0=2018,@__Month_1=2
