It also does not explain why it only returns erroneous results for males but not any of the females.
Why is your gender column wider than one character? This gives you 36 possibilities if you limit it to 'just' numbers and letters.

This will not fix it.
Group by race,gender should return only one row for each unique combination of both columns.
I can not help on this except advising to check the ASCII for both columns or check for special characters in these columns if they are wider that one char.

Denham,
Your "group by" does not match what you are selecting, thus the results are wrong.
Change your query as follows:
select race||','||gender,count(*)
from pers
group by race||','||gender
Hope this helps.

Hello Gurus,
I have a problem which I hope someone can help me with.
I am trying to clean up some data on a table. This table happens to be a personnel table.
In this table there are two columns RACE and GENDER.
The select used is :
select race||','||gender||','||count(*)
from pers
group by race, gender;
The result is as follows:
A,F,62
A,M,613
A,M,35
A,,15
C,F,34
C,M,198
C,M,4
C,,2
I,F,13
I,M,69
I,M,1
W,F,205
W,M,972
W,M,28
W,,15
The problem is that the result returns double Ms, M indicating Male. As highligthed above
I have tried converting to ascii to see if they are different in anyway but both Ms return ascii 77.
Does anyone have any thoughts on this?
TIA
