RE: SQL Column ranges into rows

This might work as a query, but not within a view:

WITH
cte1 AS
(SELECT code, begindate
FROM qtemp/t1
GROUP BY code, begindate),
cte2 AS
(SELECT b.code, a.enddate
FROM qtemp/t1 a JOIN cte1 b USING(code,begindate)
WHERE b.begindate <> a.enddate)
SELECT * FROM cte1
UNION ALL
SELECT * FROM cte2
ORDER BY 1,2

So try this instead:

CREATE VIEW myView (code,theDate) AS (
SELECT code, begindate
FROM qtemp/t1
GROUP BY code, begindate
UNION ALL
SELECT a.code, a.enddate
FROM qtemp/t1 a JOIN
(SELECT code, begindate
FROM qtemp/t1
GROUP BY code, begindate) b USING(code,begindate)
WHERE a.enddate <> b.begindate)

Then to get it in the order you want, you'll need to add the ORDER BY to the
SELECT that goes against this view:

SELECT * FROM myView ORDER BY 1,2

Subject: SQL Column ranges into rows

Wresting with some database conversion issues. Actually, I don't want
to the database to change, I want my application that accesses these
different databases to change as little as possible so building views to
present the data in a similar fashion is what I am after.

I have a table that could either be in this format:

code, date
with data that looks like this:

'test', 20080115
'test', 20080116
'test', 20080117
'test', 20080118

OR I could have a table that looked like this:

code, begin date, end date
'test', 20080115, 20080118

What I would like do is have a view that structures the second table
like the first. If the two dates are the same, you get one row with
code and date. If you have a range of dates that span 6 days (for
example), then there would be 6 rows generated by the view.

Is this possible?

Thanks
