Title: Strange Data issue.....

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.

Subject: Strange Data issue.....

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
