Here is my predicament:
I have a file that contains 3 fields
• User Profile name

Apparently: OPER

• Box Size

Apparently: BOX_SIZE

• Count

Apparently: SEL0003

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

So apparently either the SELECT in a CREATE TABLE or CREATE VIEW.?

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

Other than the missing comma and the extraneous comma? Define "problem"? If just those two problems, then try the following revision for resolution:

case BOX_SIZE when not in ('0', '1', '2', '3', '4',
'5', '6', '7', '8', '9') then
SEL0003 end as Count_Other

IIRC the BETWEEN predicate is inclusive, so assuming any /normal/ Sort Sequence (SRTSEQ) [other than a custom table (TBL)], then the following is an alternative:

case BOX_SIZE when not between '0' and '9' then
SEL0003 end as Count_Other

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

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