Date series generation using pure SELECT - SQL?

Date series generation using pure SELECT - SQL?

Date series generation using pure SELECT - SQL?

Hello all,

Can a record containing a beginning covered date of say, 2015-06-01 and an ending covered date of 2015-06-05 be generated to become five (5) separate records having individual date of the covered dates using pure SELECT - SQL only? If so, how?

RE: Date series generation using pure SELECT - SQL?

try this

with dtes as
select end_date - start_date diff ,start_date
select to_date('30-apr-15') end_date, to_date('01-jan-15') start_date
from dual
SELECT dtes.start_date + LEVEL the_dte
FROM dual,dtes
CONNECT BY LEVEL <= dtes.diff

I like it!


"Once a king, always a king. But being a knight is more than enough."
This may be an instance where meaning is lost in interpreataion.

This PUN is best understood spoken rather than written as night and knight are pronounced the same...
"Once a king, always a king. But once a night is enough."

This kind of pun is similar in structure to...
"Time flies like an arrow. Fruit flys like a banana."

But in both cases the category of relation switches, resulting in the an irony of a pun, a play on words.

"King" relates to "knight" but switches to "night".
"Time flies like" relates to "Fruit flys like," but the fleeting time category of similarity to an arrow switches to a Fruit fly that is not fleeting but attracted to a banana.
