What about something like
Expand|Select|Wrap|Line Numbers
  1. SELECT SUM(IF(result=pass,1,0)) AS cp,
  2. SUM(IF(result=fail,1,0)) as cf,
  3. SUM(IF(result=absent,1,0)) as ca
Not sure if this will work

@code green
It does. I just tried it. (Had to know if it worked xD)
You forgot to quote the strings tho.

Nice thinking, btw. My mind was already going for multiple self joins or sub-queries :P

Thanks! Multiple self-join was also in my thoughts. Probably got solution because I am always confusing COUNT and SUM

  1. SELECT COUNT( IF(PASS_FAIL='P',1,0)) AS cp,COUNT ( IF(PASS_FAIL='F',1,0)) as cf,COUNT( IF(PASS_FAIL='A',1,0)) as ca
  2. FROM cm0909
  3. WHERE (((cm0909.YEAR)=2008) AND ((cm0909.STU_TYPE)=1) AND ((cm0909.SEX_CODE)="M"));
THIS GIVES ERROR
ERROR UNDEFINED FUNCTION IF IN EXPRESSION

Which database system are you using?
Only hits I can get on that error are related to Access, not MySQL.

In which case you could try IIF instead of IF. (I think.)

Well, MySQL queries and Access queries aren't exactly the same.
You shouldn't expect MySQL queries to work flawlessly under Access, nor the other way around.

Also, these sort of details are handy for us to have before hand, so we don't waste time debugging Access errors for perfectly fine MySQL queries.

Discussing two separate topics in the same thread is generally not a good idea, and we avoid that whenever possible.

So if you want to start a discussion on your import problems, please post your question in a new thread.
Make sure to post all relevant information, such as the details on your MySQL server, your previous attempts to import your data and why/how you were unsuccessful.

Thanks.
