Need help in writting the sql

The sql
select 'alter system kill session '||sid||','||serial#||';' from v$session where username= 'EV05';
give the output in the below given form
alter system kill session 69,38769;
But i need the output to be
alter system kill session '69,38769';
Can some one re-writes the sql select statment,
Thanks
Naveen

Naveen,
This isn't the forum for help with writing SQL - rather with using the SQL Developer product. In future, I would suggest that you use the SQL and PL/SQL forum for these sorts of questions.
However, to answer your question this time, you can include a ' in a string by having two together ie 'fred''s' will return the string fred's.
The following SQL will give you the result you want:
select 'alter system kill session '''||sid||','||serial#||''';' from v$session where username= 'EV05';

Need Help in correcting the sql statement

H Experts,
I am not if I can post this query in this section, but as I am executing this statement on repository DB , I assumed to post here.
I have a requirement to calculate the database sizes from the tables in repository.
table 1 : MGMT$DB_TABLESPACES_ALL : has the information on all the tablespace information from each database. and it has information of all the databases.
table 2: MGMT$DB_REDOLOGS_ALL : has the information on all the redolog files information from each database. and it has information of all the databases.
Now to calculate the size of each database , we need to collect the sizes from both tables and then need to add.
below is the sql i prepared and sql didn't return and systax error , but the final output is completely wrong. Seems like its multiplying the data somewhere and getting the wrong information.
please help me in doing the required modifications.

Need Help with Creating the SQl query

Hi,
SQL query gurus...
INFORMATION:
I have two table, CURRENT and PREVIOUS.(Table Defs below).
CURRENT:
Column1 - CURR_PARENT
Column2 - CURR_CHILD
Column3 - CURR_CHILD_ATTRIBUTE 1
Column4 - CURR_CHILD_ATTRIBUTE 2
Column5 - CURR_CHILD_ATTRIBUTE 3
PREVIOUS:
Column1 - PREV_PARENT
Column2 - PREV_CHILD
Column3 - PREV_CHILD_ATTRIBUTE 1
Column4 - PREV_CHILD_ATTRIBUTE 2
Column5 - PREV_CHILD_ATTRIBUTE 3
PROBLEM STATEMENT
Here the columns 3 to 5 are the attributes of the Child. Lets assume that I have two loads, One Today which goes to the CURRENT table and one yesterday which goes to the PREVIOUS table. Between these two loads there is a CHANGE in the value for Columns either 3/4/5 or all of them(doesnt matter if one or all).
I want to determine what properties for the child have changed with the help of a MOST efficient SQL query.(PARENT+CHILD is unique key). The Database is ofcourse ORACLE.
Please help.
Regards,
Parag

Hi,
The last message was not posted by the same user_name that started the thread.
Please don't do that: it's confusing.
Earlier replies give you the information you want, with one row of output (maximum) per row in current_tbl. There may be 1, 2 or 3 changes on a row.
You just have to unpivot that data to get one row for every change, like this:
WITH     single_row AS
     SELECT     c.curr_parent
     ,     c.curr_child
     ,     c.curr_child_attribute1

     ,     c.curr_child_attribute3
     ,     DECODE (c.curr_child_attribute1, p.prev_child_attribute1, 0, 1) AS diff1
     ,     DECODE (c.curr_child_attribute2, p.prev_child_attribute2, 0, 2) AS diff2
     ,     DECODE (c.curr_child_attribute3, p.prev_child_attribute3, 0, 3) AS diff3
     FROM     current_tbl    c
     JOIN     previous_tbl   p     ON c.curr_parent     = p.prev_parent

     WHERE     c.curr_child_attribute1     != p.prev_child_attribute1
     OR     c.curr_child_attribute2     != p.prev_child_attribute2
     OR     c.curr_child_attribute3     != p.prev_child_attribute3

Debonfort,
I'd like to ask a few questions for clarification.
1. What programming language are you using?
2. Are you looking for more programming assistance and calculations? Or getting data from the 1530?
3. Which version of NI-DAQ are you using?
4. What DAQ board are you connected to?
I look forward to your responses. Perhaps other users will be able to help more too with your answers.

Needs help for tuning the sql

Hi
I have a query which will read one fact table and 4 dimension table.fact table contains millions of records
Can u suggest me how can i tune my query which uses the fact table to get the best performance.

Which version of the database are you using? Have you enabled Star Transformation? What does the explain plan look like? Is this intended for building a materilaized view or as the basis for running an ad hoc report?
We created bit map indexes on the joining columns.bitmap indexes or bitmap-join indexes?

Need help in rewriting a sql query

Can any one please tell me if there is any utility that can help me correcting the sql I have I need to tune the query as its taking lot of time. I want to use some tool that will help me re-formating the query.
Any help in this regard will be highly appreciated.

If you think that Oracle SQL Tuning Tools like SQL Tuning Advisor and SQL Access Advisor are not helping.
You might look into thrid party tools like Quest- SQL Navigator and TOAD.
But I don't advise this based on the following:
Re: Oracle Third Party Tools and Oracle Database
Oracle have enough tools of its own to satisfy the various needs.

I Need Help to Access The Source Code From A Form to Know the Calculation Formula

Hi,
I Need Help to Access The Source Code From A Form to Know the Calculation Formula. The application is a windows form application that is linked to SQL Server 2008. In one of the application forms it generates an invoice and does some calculations. I just
need to know where behind that form is the code that's doing the calculations to generate the invoice, I just need to get into the formula that's doing these calculations.
Thank you so much.

Hi,
Thanks for the reply. This is a view and [AmountDue] is supposed to be [CurrentDueAmount] + [PastDueAmount] - [PaidAmount]. The view is not calculating [PaidAmount] right . Below is the complete code of the view. Do you see anything wrong in the code ?

Need help in optimizing the process

I need help in optimizing my process. Here is what am I doing:
I have two tables table A and table B. table A has list of names and table B has name and ID. Right now I am loading name into cursor from table A and for each name from the cursor I try to match with name in table B to get the ID. This process takes very long to complete. I need help to replace PL/SQL with SQL if possible. I am using oracle utl_match to match the best possible record in table B. table B sometimes returns multiple matching records. I take the top nearest match name and ID for my use (there is not always one to one match)
Any idea or help will be appreciated. Thanks

always provide create table and sample data instert statements when asking a question. also, provide your database version.
because you're using utl_match, you can't really use an index, there must be a cartesian join on the two tables so it may always be slow.
however, here's a sample SQL that you may be able to make use of:
with n as (select 'KATHERINE' person_name from dual
             union all
             select 'STEVE' from dual
             union all
             select 'BRUCE' from dual)
    ,nid as (select 'CATHERINE' person_name, 1 NID FROM DUAL
             union all
             select 'STEFAN', 2 from dual
             UNION ALL
             select 'STEVEN', 2 from dual
             union all
             select 'CATHY',3 from dual)
select n_name, nid
from (
        select n.person_name N_NAME
              ,nid.person_name
              ,nid.nid
              ,ROW_NUMBER() OVER (partition by n.person_name ORDER BY utl_match.jaro_winkler_similarity(n.person_name,nid.person_name) DESC) jws_ORDER
          from n
          join nid on (utl_match.jaro_winkler_similarity(n.person_name,nid.person_name) > 70)
where jws_order = 1;

Need help in finding the number of occurrences of a pattern.

Hi All,
I need help in finding the number of occurrences of a pattern in a table's column's data.
Consider sample data - one row's column from a table:
"S-S-S-A-S-S-P-S-S-B-S-A-P-S-S-C"
My requirement is:
I should get the count of S's which are immediately preceded by A or P.
for the above data i should get count as 3+2+1=6 (S-S-S-A, S-S-P, S-A)
The pattern data is stored as VARCHAR2 type.
Thanks in advance,
Girish G

I am sure there exists a better way then this one:
SQL> with dt as
2 (select 'S-S-S-A-S-S-P-S-S-B-S-A-P-S-S-C' str from dual)
3 SELECT SUM(Regexp_count(Regexp_substr(str, '(S\-?)+(A|P)+', 1,
4                                     Regexp_count(str, '(S\-?)+(A|P)+') - (
5                                                  LEVEL - 1 )), 'S')) len
6 FROM   dt
7 CONNECT BY LEVEL <= Regexp_count(str, '(S\-?)+(A|P)+')
8 /
       LEN

CASE WHEN TRUNC(b.DATE) +90 = TRUNC(SYSDATE) THEN -90 WHEN TRUNC(b.DATE) +30 = TRUNC(SYSDATE) THEN -30 ELSE 0 END AS T_DATE FROM TABLE_B b
INNER JOIN TABLE_A a ON (a.T_ID_ = b.T_ID_) LEFT JOIN TABLE_C c ON b.PRODUCT = c.PRODUCT
WHERE b.STATUS = 'T' AND (b.TYPE = 'ACTION'
AND ( TRUNC(b.DATE) + 1 = TRUNC(SYSDATE) ) ) AND b.PRODUCT = 2;
Note: Indices on the join columns are available in the respective tables
Please let me know if there is any better way to write it.

Help me write a SQL query; urgent

Hi, can somebody please help me write a SQL query.
I have 3 tables each with the same column names (Col1, Col2, Col3). Col1 is PK with Unique Constraint.
I wanted to add values of Col2 and Col3 (from all 3 tables) and put it in a separate table (i.e aggregated) of all values found in Col1.
Does anybody help me please ?
thanks alot.

Please don't mark your question as urgent. You've been around here long enough that you should know that it will not get your question anwered any faster, and may just irritate people into not answering at all.
I'm not sure exactly what you want.
Are you saying you want t1.c2 + t1.c3 + t2.c2 + t2.c3+ t3.c2 + t3.c3 for the rows that have the same c1 in all three tables?
If so, it would be like this, I think: insert into t4
select t1.c1
, t1.c2 + t1.c3 + t2.c2 + t2.c3+ t3.c2 + t3.c3
from t1, t2, t3
where t2.c1 = t1.c1
and t3.c1 = t1.c1If that's not what you want, please clarify.
And next time maybe you should post your SQL question in a SQL forum.

Help to write a sql

Hi ,
I need help in putting a sql together for the ones listed below:
I have 2 queries and I need to put it in a format that I can use to run my sql .
select count(TRANSACTION_SID) from
(select EFFECTIVE_DATE, CREATION_DATE, ORG_SID, TRANSACTION_SID, DP_COUNT, DV_COUNT, TOTAL_SIZE,
rank() over ( partition by transaction_sid order by effective_date desc) rank
from Nightly_Inventory where effective_date<= to_date ('2008-12-03', 'yyyy/mm/dd') and org_sid='243')
where rank=1 and transaction_sid NOT IN (select transaction_sid from NIGHTLY_DELETED where effective_date<= to_date ('2008-12-03', 'yyyy/mm/dd'))
minus this:
select count(TRANSACTION_SID) from
NIGHTLY_DELETED where effective_date<= to_date ('2008-12-03', 'yyyy/mm/dd')
and transaction_sid IN (select TRANSACTION_SID) from
(select EFFECTIVE_DATE, CREATION_DATE, ORG_SID, TRANSACTION_SID, DP_COUNT, DV_COUNT, TOTAL_SIZE,
rank() over ( partition by transaction_sid order by effective_date desc) rank
from Nightly_Inventory where effective_date<= to_date ('2008-12-03', 'yyyy/mm/dd') and org_sid='243')
where rank=1 and transaction_sid NOT IN (select transaction_sid from NIGHTLY_DELETED where effective_date<= to_date ('2008-12-03', 'yyyy/mm/dd')) )
I would really really appreciate your help if I can get this working .
thanks .

Hi,
Do you want a single query that shows you the difference?
If so, you can do this:
SELECT    (
          select count(TRANSACTION_SID) from
          (select EFFECTIVE_DATE, CREATION_ ... -- your first query
          select count(TRANSACTION_SID) from
          NIGHTLY_DELETED where ... -- your second query
FROM      dual;There might be a much more efficient way, depending on what the two queries do.

I need help understanding how the Apple components integrate to create a system across all my devices?

I need help understanding how the Apple components connect to create a whole system across all my devices?
Is there a resource that describes current system and associated functionality?
For example:
Buy A, B, C to achieve "X"
You will need:
an internet provider which supports <specs>
add D to achieve "Y"
You will need:
an internet provider which supports <specs>
add "E" to achieve "Z"
You will need:
an internet provider which supports <specs>
For example, I am looking at the Gen 6 Airport extreme. For intended performance do I need broadband? if so what are the specs, or will basic internet service suffice? Do I need the internet provider's modem or does the Airport extreme replace that? And then I think, if I am doing this, I should also look at Apple TV....What do I need and Why? Then I look at the New Desk top coming out in the fall, and I think well, if I wait and get this, what does this component do for the system, and what becomes redundant? What does this awesome desktop do for my ability to sit and use a new macbook air when I travel or sit on the couch in my PJs?
If there was a place that plainly stated "if you buy the new dektop you can configure a system including only these components and achieve <this result> and by adding <additional components> you will achieve this result.
I have been to the genius store a few times, but I come out of there more confused unless I have SPECIFIC questions or already know what to buy.
A "System Configuration App" would be a really great sales tool--Just saying.

I have no idea what "fully optimized" means.
No Apple device will let you watch broadcast TV. The Apple TV is a good option for watching streaming TV from iTunes, NetFlix and Hulu. If you want to watch from other sources, you may need to look at other devices.
Any Mac computer or iPad will allow you to surf the web.
What business software?
Time Capsule is a good option for back ups.
Update what across all devices?
For accessing documents from all devices, a service like Dropbox is your best bet.
I have no idea what "step as far away from an internet provider as possible" means. If you want Internet access, you need an Internet provider.
Lighting fast speed for what? Processor? The specs are listed for all devices in the Online Store. Internet? We're back to the service provider.
Technology changes. The only way to keep pace with it beyond a couple of years is to buy new stuff.
The bottom line is you need to look at the specs for devices availble and at your budget and decide what best meets your needs. If you are unable to do that on your own, there are lot of technology consultants out there who will, for a fee, look at your exact situation, make recommendations and even handle the purchase and set up. Perhaps that would be the best route for you.
Best of luck.
