finding earliest/latest stored date for record

While Dylan\'s way would work, the better way is to use the min() and max() summary functions.

 

Although it\'s unclear, you seem to suggest you have a table with at least these columns:

 

Table TableA

------------------------

id | INT

somedate | DATE

... etc

 

 

What\'s confusing is you state you could have multiple rows which have the same id, only the somedate would be different... or in other words, you have \"groups\" of the same id in TableA.

 

If that is true, then this would get you the earliest date for each id

 


SELECT MIN(somedate) as mindate, MAX(somedate) as maxdate FROM TableA  GROUP BY id

Thanks all,

 

for gizmola, the tables are in the following form:


UniqueID   Reference       Date              etc

   1           1        2003-09-09

   2           1        2003-08-09

   3           2        2004-01-17

   4           1        2002-12-29



etc etc
