I have a column of dates (field93) in this format:

MMDDYY

Currently I am using:

ORDER BY field93 DESC

However, with the new year - this doesn't work because:

120108 shows up before 010709

How can I fix this?

You should not store it in this format. This is why most software stores date like (YY)YYMMDD, so it can be sorted.

You should convert your dates like Marco said so you can use a reliable search method.
I can't think of any way to generally find what your looking for without searching for specific smal intervals.

Yes you could sort by substrings, but that could easily become a performence killer.

It is not a VB3 engine, just a parsed copy!
