This is true for other numeric datatypes as well. Spaces or empty strings are implicitly converted to zero
DECLARE @MyNum intSET @MyNum = ' '
-- attempt arithmetic operation
Select @myNum * 4
-- result is 0, not an error.
Good point, but I would like it more if SQL Server throws an exception and let developers know upfront that it's wrong to assign string/character values to an integer data type.
