>>>Hi, Is is possible to use an sql statement(s) to count and number duplicates? The original table looks something like this, showing an excerpt where there are three entries for one date:
>>>
>>>

>>>Mdate            Vs
>>>05/28/2013     v1
>>>05/28/2013     v1
>>>05/28/2013     v1
>>>

>>>
>>>The following is a start in that it will give me a table that shows how many duplicates exist for each date.
>>>
>>>

>>>SELECT mdate,COUNT(mdate) FROM ch5 ;
>>>    INTO TABLE dups;
>>>    GROUP BY mdate ;
>>>    HAVING COUNT(mdate) > 1
>>>

>>>
>>>Here is a part of the report that the above produces:
>>>
>>>

>>>mdate         cnt_mdate
>>>05/28/2013   3
>>>08/28/2013   2
>>>

>>>
>>>And by using set relationship and a do while loop, I can count and label the duplicates. But I was just wondering if an SQL statement(s) could do it all? The final output that I need is::
>>>
>>>

>>>Mdate            cnt/date    Vs
>>>05/28/2013     1              v1
>>>05/28/2013     2
>>>05/28/2013     3
>>>

>>>Thanks,

>>To add sequential numbers to records, read the section "Including record numbers in results" in http://www.tomorrowssolutionsllc.com/Conference%20Sessions/Solving%20Common%20Problems%20with%20VFP%27s%20SQL.pdf. Basically, you use one query to collect the results and another to add RECNO() to the field list.

>Thank you! The part you refer to is on p. 19. But I don't want to insert recno()'s per se. (I shouldn't have skipped at step.) I wondered if I could number the instances where there are multiple occurances for a given date, perhaps resulting in a numbering schema as shown in cnt/date or new_index; because, once I see something like this:

>Mdate            cnt/date            new_index            Vs
>05/28/2013        1                   2013052801         v1
>05/28/2013        2                   2013052802         v2
>05/28/2013        3                   2013052803         v3

Ah, yeah, what I missed was numbering within each group, once you've selected the records of interest. I see that you're using SQL Server, though, so in fact, this is easy using OVER and the ROW_NUMBER function. Check out this article on my site: http://www.tomorrowssolutionsllc.com/Articles/Getting%20the%20Top%20N%20for%20each%20Group.pdf, in particular, the part that begins with "The SQL Server Solution."
