>>>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:
>>
>>
>>SELECT *
>> FROM ch5
>> WHERE mdate IN (
>> SELECT mdate FROM ch5 ;
>> GROUP BY mdate ;
>> HAVING COUNT(mdate) > 1)
>>
>>
>>>
>>>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,

Why would it? ch5 is a table isn't it? You used it in your example. Sorry, but this is the way to do it. You must have done something else wrong.
