Thanks, that's very helpful. As Chris noted earlier, the [LNK_CreatedBy_ID] column is defined as [numeric](18, 0) NOT NULL, but the procedure contains CONVERT(datetime,E.[b]LNK_CreatedBy_ID[/b],103) as [LNK_CreatedBy_ID]. Are you intending to try to convert this number to a date/time using style 103?
