this is a simplified query where I am passing a value to @sAlphaGroup but sometimes that value is null and I need to deal with this in one line...

this doesn't work (no records returned where in this case I need all records):

declare @sAlphaGroup varchar(20)
set @sAlphaGroup = null

Select
      *
From dbo.Projects As P
     Join dbo.tblProjectProducts As Product
          On Product.ProjectId = P.ProjectId
Where
      P.IsActive = 1
     And Product.IsActive = 1
     And Product.IsOnWebSite = 1
     AND (@sAlphaGroup IS NOT NULL OR PP.ProductTitle LIKE '[' + @sAlphaGroup + ']%')
Order By
    P.Title
