Re: How to use SQL CASE

Gary,

I think Alan is trying to use CASE to PIVOT, if he wants two columns, then
the correct SQL would be, as you hinted at


SELECT OPER,
case BOX_SIZE when '1' then 'Count1',
when '2' then 'Count2',
when '3' then 'Count3',
when '4' then 'Count4',
when '5' then 'Count5',
when '6' then 'Count6',
when '7' then 'Count7',
when '8' then 'Count8',
when '9' then 'Count9',
when '0' then 'Count0',
ELSE 'Count_Other'
END AS SEL0003
FROM file

Alan,
I'm not following your SELECT statement example.

The following is an example that may be similar to what you want:

SELECT wekday,
CAST ( CASE WHEN wekday = 1 THEN 'Monday'
WHEN wekday = 2 THEN 'Tuesday'
WHEN wekday = 3 THEN 'Wednesday'
WHEN wekday = 4 THEN 'Thursday'
WHEN wekday = 5 THEN 'Friday'
WHEN wekday = 6 THEN 'Saturday'
WHEN wekday = 7 THEN 'Sunday'
ELSE 'Day Error'
END AS CHAR(9) ) AS wekdaytxt
FROM library1/om06


Output from the sql example:

Week WEKDAYTXT
Day
2 Tuesday
5 Friday
5 Friday
2 Tuesday
2 Tuesday
4 Thursday
2 Tuesday
4 Thursday
4 Thursday
1 Monday
3 Wednesday
4 Thursday
2 Tuesday
4 Thursday
5 Friday

Subject: How to use SQL CASE

Hi everyone
Before I forget - we are on V5r4 - hopefully moving up to the latest
release very soon Here is my predicament I have a file that contains 3
fields User Profile name Box Size Count

Box size can have valid values of '0', '1', '2', '3', '4', '5', '6', '7',
'8', '9'
I want to create a new file with the following SELECT OPER, case BOX_SIZE
when '1'then SEL0003 end as Count1, case BOX_SIZE when '2'then SEL0003 end
as Count2, case BOX_SIZE when '3'then SEL0003 end as Count3, case BOX_SIZE
when '4'then SEL0003 end as Count4, case BOX_SIZE when '5'then SEL0003 end
as Count5, case BOX_SIZE when '6'then SEL0003 end as Count6, case BOX_SIZE
when '7'then SEL0003 end as Count7, case BOX_SIZE when '8'then SEL0003 end
as Count8, case BOX_SIZE when '9'then SEL0003 end as Count9, case BOX_SIZE
when '0'then SEL0003 end as Count0, case BOX_SIZE when not in ('0', '1',
'2', '3', '4', '5', '6', '7'
'8', '9',) then
SEL0003 end as Count_Other FROM file

It's the last case clause that I am having a problem with case BOX_SIZE
when not in ('0', '1', '2', '3', '4', '5', '6', '7'
'8', '9',) then
SEL0003 end as Count_Other



I want to capture the count if its not a valid value into its own field

I hope this makes sense
As always - all response gratefully accepted
