I have a DB2 SQL statement which selects the required rows successfully. Since its a time consuming query, I am trying to convert it into a view using the create view statement.

So my first attempt to create the view was simply to add a CREATE VIEW AS at the beginning of the first statement. This resulted in the error below:
A column list must be specified because the result columns are unnamed.
I am failing to understand this error as the column headings are indeed specified as the select works without issues. All columns are displayed with appropriate headings.
However I tried to modify the query by adding the below instead of the simple create view.
create view pavt.v1 (v1,v2,v3,v4,v5,v6,v7,v8,v9,v10,v11,v12,v13,v14,v15,v16,v17,v18,v19,v20,v21,v22,v23,v24,v25,v26,v27,v28,v29,v30,v31,v32,v33,v34,v35,v36) as
This seemed to have worked and the view was created in library PAVT. However when I run a select on the view, I get an aritmetic overflow error with DB2 error code of -802.
I dont understand this as I am able to view the results but the issue comes only while attempting to create the query. Can somebody guide please?
A more detailed error description is below:
Message . . . . : Select or omit error on field
Cast(Translate(ORDER_14.ORPTIM, *UNNAMED Table) AS member V.
Cause . . . . . : A select or omit error occurred in record 0, record format
*FIRST, member number 1 of file V in library PAVT, because of condition 1 of
the following conditions:
1 - The data was not valid in a decimal field.
At this moment what I really want to know is if the method I am following to create the view is correct (atleast as far as the syntax goes). Maybe the error I am seeing is a data error?
Edit-1:
create view pavt.CCC1 as

The first error is because in your 2 main SELECT statements (being UNIONed together) you have different column names - so the View doesn't know what to call them and is requiring you to explicitly name them e.g. the first column in each statement:
SELECT a.orodr# orodr_ ...
SELECT d.orodr# as ordddd ...
For the 2nd error, what is the datatype of the ORPTIM column?
I'm guessing that this type of construct is causing the issue:
CASE orptim
WHEN 0
THEN Varchar(0)
ELSE CONCAT(CONCAT(SUBSTRING(orptim, 1, 2), ':'), SUBSTRING(orptim, 3, 4))
If orptim is a number/decimal then "WHEN 0" will work but "SUBSTRING(orptim, 1, 2)" won't - as you can't substring a number. If orptim is a string then "WHEN 0" w=may be casuing problems.
if i have a column in which ten digit values occurs like Column A = 11111000 so how to show this value in sql like (List,Add,Edit,Delete,Export) in sql.
there is a condition means if first position have 1 then it show List, If second Position have 1 it show Add, third position have 1 then Edit, fourth position have 1 then Delete, fifth position have 1 then Export.
If the value is a string, you can do:
select stuff( ((case when substring(a, 1, 1) = 1 then ',List' else '' end) +
(case when substring(a, 2, 1) = 1 then ',Add' else '' end) +
. . .
), 1, 1, '')
The logic is similar for bitwise operators:
select stuff( ((case when a & 2^9 then ',List' else '' end) +
(case when 2 & 2^8 then ',Add' else '' end) +
. . .
), 1, 1, '')
Maybe Substring function can help you to identify these values
select
id, ColumnA,
case when substring(ColumnA,1,1) = '1' then 'X' end as List,
case when substring(ColumnA,2,1) = '1' then 'X' end as [Add],
case when substring(ColumnA,3,1) = '1' then 'X' end as Edit,
case when substring(ColumnA,4,1) = '1' then 'X' end as [Delete],
case when substring(ColumnA,5,1) = '1' then 'X' end as [Export]
from Table1
I update the query according to comment
select
id, ColumnA,
stuff(
case when substring(ColumnA,1,1) = '1' then ',List' else '' end +
case when substring(ColumnA,2,1) = '1' then ',Add' else '' end +
case when substring(ColumnA,3,1) = '1' then ',Edit' else '' end +
case when substring(ColumnA,4,1) = '1' then ',Delete' else '' end +
case when substring(ColumnA,5,1) = '1' then ',Export' else '' end
,1,1,''
)
from Table1
After some previous help on how to approach a problem I am having with some legacy code, it seems like the best approach for my issue is to concatenate case statements to return a value I can parse out in PHP.
I am trying to do something like this, but it is returning many rows, and eventually getting this error:

Well, this is embarrassing.
When I was making my changes to the stored procedure, I had inadvertently placed a call to the same procedure at the bottom. So I was recursively calling the same procedure over and over again. DOH.
