Hi, I have some data in SQL where I need to remove duplicates based on certain criteria.  A sample of the data is follows:-

Property      Item      Date      Location
100      G7FIRE      10/10/2010      LOUNGE
100      G6BBU      11/10/2010      LOUNGE
100      G7FIRE      12/10/2010      KITCHEN
101      G6BBU      13/10/2010      LOUNGE
102      G7FIRE      14/10/2010      KITCHEN
105      G7FIRE      10/10/2010      LOUNGE
105      G6BBU      11/10/2010      LOUNGE
105      G7FIRE      12/10/2010      KITCHEN


For properties 100 and 105 there is a G6BBU and a G7FIRE in the SAME location of LOUNGE.  If this is the case then I need to find and remove the G7FIRE.

So for properties where the is a G6BBU and a G7FIRE in the SAME LOCATION (which could be lounge, kitchen, anywhere) I need to remove the G7FIRE line?

Is there an update query that I can run to apply this?

Many thanks,
Deborah
