Can we use EXISTS in where condition

hi all,
can we use EXISTS (instead of IN) in where condition of a query which is not part of a subquery ?
for e.g:
update gpf_vou_sm set up_amt=0 where src_cd exists ('1101','1201');
the query works fine with the IN operator in place of EXISTS.
anybody please help.
thomas k prakash

Hi:
You can use EXISTS in where clause but not in that syntax.
UPDATE gpf_vou_sm g
   SET up_amt = 0
WHERE EXISTS (SELECT 1
                 FROM gpf_vou_sm
                WHERE src_cd IN ('1101', '1201') AND id = g.id);Using IN in your case is better...

Can I use existing games in new Games Centre

Just updated my 3gs to OS4.1 with no problems, my question is:-
Can I use existing games already bought & paid for at the iStore in the new Games Centre? Iv'e tried dragging them in to no avail i'm begining to think in that money making fashion of Apple that you can only use newly purchased games.

You mean in the money making fashion of Apple which doesn't make any money off the sale of paid apps with all free apps hosted and distributed by Apple at no charge to the developers with free apps? Apple keeps a percentage of the sales price for paid apps to cover associated expenses. The bulk of the revenue for paid apps is paid to the app developers with the developer for a paid app setting the price for their app.
An app must be updated by the developer for the app to be included with the Game Center no different from an app needing to be updated by the developer for iOS4 to be suspended when leaving the app instead of being quit.

I find it annoying that you can't use aliases in where statements

I find it annoying that you can't use aliases in where
statements
for example:
SELECT TOP 1
CAST(amount
/ ( CASE WHEN ISNULL(rate, 0) <> 0 THEN rate
ELSE 1
END ) AS NUMERIC(10, 2)) AS num
FROM table
WHERE num > 1
ORDER BY num
Are there any workarounds?

> I find it annoying that you can't use aliases in where

This isn't really (or... "at all") a CF question. You're
better off asking
this sort of thing on a SQL Server forum.
You could use a derived table, I guess:
select top 1 num
from (
SELECT
CAST(amount
/ ( CASE WHEN ISNULL(rate, 0) <> 0 THEN
rate
ELSE 1
END ) AS NUMERIC(10, 2)) AS num
FROM table
where num > 1
order by num
(that might not preserve the intent of you SQL (sorry: it's
late, I'm
tired), but you get the idea.

Can I use existing repository for master repository?

can I use existing repository (for example repository from oracle designer )
for master repository? could you give me please an explanation
thanks

You can use Existing repository for your master Repository.
Or you can create a new schema in your database and create
master repository on that schema.
I hope this answers your question

you can do
WHERE
CASE WHEN (something) THEN
CASE WHEN EXISTS (SELECT * from ...) THEN 1 ELSE 0 END
WHEN (something else) THEN
CASE WHEN EXISTS (SELECT * from ...) THEN 1 ELSE 0 END
END = 1Looking at your current query, it looks like all those exist statements could be a lot neater, maybe like:
WHERE (69309,242528,34694) IN
(SELECT project_id,task_id,award_id FROM
(Select project_id,task_id,award_id,transaction_id,source_name

UNION ALL
Select project_id,task_id,award_id
xxdl_sc_mng_gns_pta_inv_hc_v
...) x
where a.transaction_id = x.transaction_id
and a.source_name = x.source_name
)or put the tuple in the where clause at the bottom

Can we use concatenate in where clause of a select query

I have a select query as follows....
    SELECT ebeln ebelp belnr vgabe bwart DMBTR
                             FROM ekbe
                             INTO TABLE i_ekbe
                             FOR ALL ENTRIES IN i_blck
                             WHERE ebeln = i_blck-ebeln AND ebelp =
i_blck-ebelp.
Now i want to retrieve data from BKPF ..can i write a select query something like....
select * from BKPF into itab
            FOR ALL ENTRIES IN i_ekbe
            where awkey = ( conatenate i_ekbe-belnr i_ekbe-gjahr )
OR ELSE...is there any other way to link table ekbe and bseg ???

Hi Poonam,
SELECT ebeln ebelp belnr vgabe bwart DMBTR
FROM ekbe
INTO TABLE i_ekbe
FOR ALL ENTRIES IN i_blck
WHERE ebeln = i_blck-ebeln
AND ebelp = i_blck-ebelp.
select *
from BKPF
into table itab
FOR ALL ENTRIES IN i_ekbe
where belnr = i_ekbe-belnr.
If u want to check with AWKEY concatenate into seperate field and then use to check in where condition.
data: lw_awkey(20) type c.
CONCATENATE i_ekbe-belnr i_ekbe-gjahr INTO lw_awkey.
select *
from BKPF
into table itab
FOR ALL ENTRIES IN i_ekbe
where awkey = lw_awkey

(How) Can I use Existing Time Machine On New Mac Without Erasing Original TM Backups?

I just got through doing a clean install from Mavericks to Yosemite and now I'm trying to attach and recognize the original Time Machine Drive (TMD)
I chose to install as a new computer and did not choose a Time Machine backup option because the original TMD was not attached at the time of installation.
Upon arriving at the desktop and connecting my original TMD, I was able to see it in finder but Time Machine did not automatically accept it.
I am able to see the disk in Time Machine but it doesn't tell me that its got data on it .
HERE'S THE ANXIOUS MOMENT: If I select TMD, which is the original, will it overwrite all that orignal information, or will it continue adding to it?
I've read under different parts of the forum that if you go through this process during the original setup and the Time Machine drive is attached to the computer then you will be prompted to inherit the old Time Machine. Since I didn't have the drive attached, I didn't see that.
Now back to desktop and into the Time Machine utility: This option to inherit doesn't seem to exist or is obvious. The only option after selecting the drive in Time Machine is "Use Disk". If I click this, will it erase my original data or will it ask to inherit the drive? It's not very clear what will happen after I click "Use Disk".
Thanks so much to anyone who can help, Jeff

Thanks for the link. I went there but didn't find any information on how to inherit the backup history. The link says "If you’re replacing an old Mac and want the new Mac to use the backups from the old one, click Inherit Backup." At what point in the migration process does it ask "to specify whether you (I) want a new Mac to inherit a backup"? It seems like I got quite a few levels into Migration assistant and the last click that I did not click seemed like it was good to start the process without telling me anything about inheriting anything.
Any suggestions or did I not go far enough?
From Apple Website below
OS X Yosemite: If you want a new Mac to “inherit” your backup history
You can move the backup history from one Mac to another, but after the new Mac “inherits” the backup history, you can’t use the backup history on the original Mac.
You’re asked to specify whether you want a new Mac to inherit a backup if you do any of the following:
Use Migration Assistant to transfer your settings from an old Mac to a new one.
Use Migration Assistant to transfer your settings from a Time Machine backup of an old Mac to a new one.
Clone the disk you use to start your Mac, or physically move it from an old Mac to a new Mac.
Replace your computer’s main board.
If you’re replacing an old Mac and want the new Mac to use the backups from the old one, click Inherit Backup.
If you plan to continue to use your old Mac, click Create New Backup to preserve the backup history and start separate backups for the new Mac.
Connect a new backup disk to your Mac
Transfer your info from a PC

Can i use existing airport with Time Capsule

i have already bought an airport, but can i use it with Time Capsule OR do I need to buy the $299 Time Capsule wireless hard drive?

If you are telling us that you have already bought an AirPort Extreme, and that you want to connect a USB hard drive to the AirPort and use that for Time Machine backups, this is not officially supported by Apple.
Some users seem to be able to make this work, while others.....like me....who try this have nothing but problems.
To be officially supported, you need to connect a hard drive directly to your Mac for Time Machine backups or use a Time Capsule.

How can I use existing anchor point as a new one?

Can anyone help?
I'm tracing over a drawing, and I'm trying to use an existing anchor point as an anchor point for another curve. So, from c, I want to click and drag on anchor point b to make a new curve. If I click where b is, then I just delete b. Can I make b my initial anchor point so that I can use it to complete my tooth? When I get to the next teeth Ill have to do the same thing. Has anyone any ideas?

> Each tooth should be a closed path.
Why?
> If I click where b is, then I just delete b.
Ugh, turn off Auto Add/Delete Anchor Point and watch your rage levels instantly decrease. You can then put your final point anywhere you want, including smack dab on top of B.

Can I use EXISTS?

Hi, I am fairly new to sql and need help with a query...
I have two tables
Titles
Name.............Number
A...................1
B...................2
C...................3
D...................4
etc
etc
Holders
Number.........Colour
1...................Blue
2...................Red
3...................Green
etc
I want to selct all from Titles where the number does not exist within holders.number. My simple query is
Select Titles.*
where Titles.Number = Holders.Number
and Titles.Number not in (select Number from Holders)
However, both table have > 50000 records and the query takes too long to run. How can I do this using NOT EXISTS?
Thanks,
Ian

Your two choices would look something like this...
Select Titles.*
from   Titles
where Titles.Num_ber not in (select Num_ber
                              from   Holders
                              where num_ber is not null);
Select Titles.*
from   Titles
where NOT EXISTS (select 1
                   from   holders
                   where holders.num_ber = titles.num_ber)
;Run some explain plans and benchmarks to see if one is faster than the other.

Can I use existing 10g iAS install with Application Express?

I apologize if this has been addressed somewhere else, but I haven't been able to find a definitive answer yet.
I have a 10g DB installed on machine A, and have been following the instructions to install Application Express. Instead of installing another instance of HTTP_Server (from the companion CD) on machine A, I have machine B with a full 10g iAS install on it (discoverer, portal, infrastructure, etc). I would like to use machine B as the front end to access htmldb. Machine B has 2 oracle homes, one for the infrastructure and one for the BI tools/portal stuff. Which one do I configure for htmldb? From reading in this forum I think I can use the dads.conf file instead of the marvel.conf file (which doesn't exist) to add the pls/htmldb info, but I can't figure out which one to edit. I probably have something else wrong somewhere, but this would help narrow things down. Currently when I go to the following url http://machineb:7778/pls/htmldb I get "503 Service Temporarily Unavailable".
Thanks in advance for any help.
Rhonda

Sure, you can use the Application Server, no need to install another one.
You would add the configuration to the BI tools/portal stuff Oracle Home, not the infrastructure.
You don't need the marvel.conf explicitly (but this is installed per default when you install the http server from the 10g companion CD).
You could just add the DAD configuration to the dads.conf.
To make it a bit simpler I would do the following:
1) remove the entries for /pls/htmldb from your current dads.conf (if they exist).
2) follow the instructions here: http://www.oracle.com/technology/products/database/application_express/howtos/howto_useoas10g.html
And use the following for the contents of the file marvel.conf (make sure to change it accordingly for your environment (changes to make are bold):
AddType text/xml xbl
AddType text/x-component htc
Alias /i/ /home/oracle/oracle/product/10.2.0/db/htmldb/images/
