ORDER BY DATE showing NULLS first then most recent dates
@Chris, you almost have it.
ORDER BY (CASE WHEN [Submission Date] IS NULL THEN 1 ELSE 0 END) DESC, [Submission Date] DESC
[Edit: #Eppz asked me to tweak the code above as currently shown]
I personally prefer this a lot better than creating "magic numbers". Magic numbers are almost always a problem waiting to happen.
You can do something like this put the NULL's at the bottom:
ORDER BY [Submission Date] IS NULL DESC, [Submission Date] ASC
Standard SQL (ISO/IEC 9075-2:2003 or later - 2008) provides for:
ORDER BY SomeColumn NULLS FIRST
Most DBMS do not actually support this yet, AFAIK.
