Handling empty fields












0















SELECT Name,
SUM(Switch([Date] = DateAdd('d', - 7, DATE ()), NetAmount) )AS DAY1
FROM Customer
GROUP BY Name


My question is how to return the value 0 when the date is not present (an empty field). Should I use SWITCH or IIF or something else?

  • Use IIf or perhaps Nz()

  • Do you want to return all dates or a set of dates even though you might not have it? If so, then I would suggest looking at a calendar table to store the list of dates, then you could join to that table and return all dates that you need.

Take a look at this one from msdn:
http://msdn.microsoft.com/en-us/library/office/aa172237%28v=office.11%29.aspx



It shows ways to handle null.



From what you explain - I'd go with IIF
