i’ve struggled again and again on this, but can’t get it to work. been on these forums for hours now… Data set:
Row Date AccountID Column 1 1 21/02/2013 0:30 A0M8FA1003YP . 2 21/02/2013 0:30 A0M8FA1003YP . 3 21/02/2013 0:30 A0M8FA1003YP . 4 24/09/2007 12:00 A0M8FA1003YP . 5 24/09/2007 12:00 A0M8FA1003YP . 6 24/09/2007 12:00 A0M8FA1003YP . 7 12/02/2009 12:00 A023123332YP . 8 24/09/2003 12:00 A023123332YP . 9 24/09/2003 12:00 A023123332YP . 10 24/09/2003 12:00 A023123332YP .
I want to return the max value of the date column, but not just return a single row, but any rows that match that max value. I.e. In the above set I want to return rows 1, 2, 3 and 7 (all columns for the rows as well).
Row Date AccountID Column 1 1 21/02/2013 0:30 A0M8FA1003YP . 2 21/02/2013 0:30 A0M8FA1003YP . 3 21/02/2013 0:30 A0M8FA1003YP . 7 12/02/2009 12:00 A023123332YP .
I’ve got thousands of rows, and the number of matching rows to return for each ACCOUNTID will vary, some 1, some 2, some 10. Please help me!!!
UPDATE Have also tried this
Select max(ASS_SCH_DATE) over (partition by AccountID), AccountID, ASS_SCH_DATE, ACCOUNTID from #Temp3 order by #Temp3.ACCOUNTID
Results still showing extra rows.
(No column name) ASS_SCH_DATE ACCOUNTID 2013-02-21 00:30:00.000 2013-02-21 00:30:00.000 A0M8FA1003YP 2013-02-21 00:30:00.000 2013-02-21 00:30:00.000 A0M8FA1003YP 2013-02-21 00:30:00.000 2013-02-21 00:30:00.000 A0M8FA1003YP 2013-02-21 00:30:00.000 2007-09-24 12:00:00.000 A0M8FA1003YP 2013-02-21 00:30:00.000 2007-09-24 12:00:00.000 A0M8FA1003YP

Query:
SELECT t1.* FROM Table1 t1 WHERE t1.Date = (SELECT MAX(t2.Date) FROM Table1 t2 WHERE t2.AccountID = t1.AccountID)
Result:
| ROW | DATE | ACCOUNTID | -------------------------------------------------------- | 1 | February, 21 2013 00:30:00+0000 | A0M8FA1003YP | | 2 | February, 21 2013 00:30:00+0000 | A0M8FA1003YP | | 3 | February, 21 2013 00:30:00+0000 | A0M8FA1003YP | | 7 | February, 12 2009 12:00:00+0000 | A023123332YP |
