Re: Why this SQL does not work?

2001-07-11 Thread orclbabu

rownum will not work for "rownum = anything_but_1".

this is because rownum is assigend after the cursor is fetched.

oracle fetches the first row and assigns a rownum of 1, checks where rownum
= 5 condition, finds that it is not satisfied and discards the row.
it fetches another row, and since the prev row is discarded this new row
will have a rownum of 1 and so it is also discarded...

thus only if you give rownum = 1 or rownum < x it will work.

the following will not work

rownum = x  where x >1
rownum > x where x > 0

how high is healthy depends on the nature of application.

The very fact that you often repeat this in response to mails that refer to

Hi List
 
I recently got this message in my 
alert log : Picked Lapert Server scheme to generate SCNs.
 
I guess its harmless and more of a 
information only entry. But does anyone know more about it?
