Dear all,

I have a table imported into Access the structure is below.  There are 7 consecutive dates.

ID  Latitude  Longitude  19/12/2014  20/12/2014  21/12/2014 etc.

I wrote the below query and it works for that dataset, i.e. the next dataset will have dates for the following week.  Is it possible to write a query to check and delete records where all fields except e.ID, e.Latitude, e.Longitude contain "--"  (without including field names)?

Thanks

SELECT e.ID, e.Latitude, e.Longitude, e.[19/12/2014] AS Expr1, e.[20/12/2014] AS Expr2, e.[21/12/2014] AS Expr3, e.[22/12/2014] AS Expr4, e.[23/12/2014] AS Expr5, e.[24/12/2014] AS Expr6, e.[25/12/2014] AS Expr7 INTO FormattedData
FROM Export_FFDI_Valid_Python AS e
WHERE ((([e].[19/12/2014])<>"--") AND (([e].[20/12/2014])<>"--") AND (([e].[21/12/2014])<>"--") AND (([e].[22/12/2014])<>"--") AND (([e].[23/12/2014])<>"--") AND (([e].[24/12/2014])<>"--") AND (([e].[25/12/2014])<>"--"));
