Hi, I would like to get results from the two tables below where the ITM$Con_Note value is in both tables.I would also like to calculate the WeightDif field which is the difference between the two weights.Also in reality these tables are identical tables in separate identical databases on two PC's using SQL Express 2008 R2Thanks,DavidITM$Con_Note ITM$Machine ITM$Date_Time ITM$Weight ITM$Machine ITM$Date_Time ITM$Weight WeightDifABC456 ADL01 2013-09-14 20:52:39.087 1.200 ADL02 2013-09-14 20:52:39.090 1.500 0.31234567890 ADL01 2013-09-14 20:52:39.087 35.6 ADL02 2013-09-14 20:52:39.090 35.75 0.25drop table #item1drop table #itemCREATE TABLE #Item( [ITM$Con_Note] [varchar](50) NULL, [ITM$Machine] [varchar](10) NULL, [ITM$Date_Time] [datetime] NULL, [ITM$Weight] [numeric](18, 3) NULL, )Insert into #Item(ITM$Con_Note,[ITM$Machine],[ITM$Date_Time],[ITM$Weight]) values('ABC123','ADL01',getdate(),10.5)Insert into #Item(ITM$Con_Note,[ITM$Machine],[ITM$Date_Time],[ITM$Weight]) values('ABC456','ADL01',getdate(),1.2)Insert into #Item(ITM$Con_Note,[ITM$Machine],[ITM$Date_Time],[ITM$Weight]) values('ABC789','ADL01',getdate(),4.5)Insert into #Item(ITM$Con_Note,[ITM$Machine],[ITM$Date_Time],[ITM$Weight]) values('1234567890','ADL01',getdate(),35.6)CREATE TABLE #Item1( [ITM$Con_Note] [varchar](50) NULL, [ITM$Machine] [varchar](10) NULL, [ITM$Date_Time] [datetime] NULL, [ITM$Weight] [numeric](18, 3) NULL, )Insert into #Item1(ITM$Con_Note,[ITM$Machine],[ITM$Date_Time],[ITM$Weight]) values('ABC1231','ADL02',getdate(),10.75)Insert into #Item1(ITM$Con_Note,[ITM$Machine],[ITM$Date_Time],[ITM$Weight]) values('ABC456','ADL02',getdate(),1.5)Insert into #Item1(ITM$Con_Note,[ITM$Machine],[ITM$Date_Time],[ITM$Weight]) values('ABC7890','ADL02',getdate(),4.55)Insert into #Item1(ITM$Con_Note,[ITM$Machine],[ITM$Date_Time],[ITM$Weight]) values('1234567890','ADL02',getdate(),35.75)select * from #Item AS oneLEFT OUTER JOIN #Item1 AS twoON one.ITM$Con_Note = two.ITM$Con_NoteWHERE one.ITM$Con_Note = two.ITM$Con_Note
