Need help in AUTONOMOUS_TRANSACTION(pl/sql)

Hi,
I'm havaing a procedure which is calling a autonomous transaction.
I'm unable to get the changes made by the caller procedure. The commit and rollback of the session is controled by the JSP code and not in procedure.
I have gone thro doc and came to know unless commit is made in the caller procedure autonomous transaction can't get the reflected changes.
Any other way ?
Scenario
JSP -> call C1
on sucess -> commit
else -> rollback
Caller Procedure(C1) Autonomous Procedure(A1)
Insert .... Select form insert and update
Update .... of C1 (Not known:no_data_found/
call A1 old_data)
Insert ...
END Commit
END;
Regards,
Donald.

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.

Need help to redesign legacy SQL Script

Hello Experts,
I have the below code which produces a CREATE TRIGGER statement. as of now this does for updating. I need to re-design this code to add for inserting and deleting as well. I just need help in the structuring wise. I can build the logic for inserting and updating inside. I want to know how i can continue to get for "inserting" and "deleting" as well.
you will understand my question better if you go through main code, present output and required output format below.
I know this is a bad design first of all. but the below code is a legacy one. so i cant change the entire structure of the code :-( all i can do is to continue designing it to add new changes. Hence sought help from you all.
please help

Need Help with Formula using SQL maybe

I need help! I work with Crystal reports XI and usually manage just fine with the Formula editor but his one I think will require some SQL and I am not good at that.
We are running SQL 2000 I think (Enterprise Manager 8.0) Our sales people schedule activities and enter notes for customer accounts. Each is stored in a separate table. I need to find activities that are scheduled 240 days into the future and show the most recent note that goes with the account for which that activity is scheduled.
The two tables, Activities and History, share the an accountID field in common that links them to the correct customer account.   I want to look at dates in the Startdate.Activities field more than 240 days in the future and show the most recent note from the History table where the accountid's match. I figure my query will contain a join on AccountID.Activities and AccountID.History used with Max(completedate.History) but I do not understand how to word it.
I would like to perform all this in crystal if possible. I humbly request your help.
Membery

You SQL would look something like this...
SELECT
a.AccountID,
a.BlahBlahBlah, -- Any other fields you want from the Activities table
h.LastComment
FROM Activities AS a
LEFT OUTER JOIN History AS h ON a.AccountID = h.AccountID
WHERE (a.ActivityDate BETWEEN GetDate() AND DateAdd(dd, 240, GetDate()))
AND h.HistoryID IN (
     SELECT MAX(HistoryID)
     FROM History
     GROUP BY AccountID)
This method assumes that the History table has a HistoryID that increments up automatically each time a new comment is added... So a comment made today would always have a higher HistoryID that one made yesterday.
If I'm wrong and there is no HistoryID or the HistoryID doesn't increment in a chronological fashion, it can still be done but the code is a bit more complex.

Need help with min max sql

hi all, forgot i had a user name and password and haven't needed help for quite a bit since i didn't do sql for a while but now i'm back at reporting again...
Here is a sample table as i remember it:
Item     Date     Time     Time Frame     Duration     Duration Frame
A     20100926     0     5     500     10
A     20100926     600     10     500     30
A     20100926     1500     12     100     30
B     20100926     1800     28     200     40
B     20100926     2200     6     150     70
B     20100926     2600     15     600     60
B     20100926     3600     30     200     70
Results Set (expected):
Item     Date     Time     Total Duration
A     20100926     0     1600:20     --basically max (time+duration) - min(time+duration)
B     20100926     1800     2000:00
Sorry, but. I didnt put my sql statement as I wasn't planning on posting and left it at work, but, i've been looking on internet and people say to use min/max function and i've attenpted it with it works with just this table (without grouping). But as soon as i group it the values seem to mess up.
Last i remembered it gave me:
Item     Date     Time     Total Duration
A     20100926     0     1600:30     --basically max(time+duration) - min(time+duration)
B     20100926     1800     2000:70
I think it's looking at max duration which is 30&70 and hence it retrurns those values in the result set. Is it because of the max function hence it's returning this value? any help is appreciated. thanks

Okay, here we go again, repost, hopefully okay this time:
Hi Madhu, okay, just got to work: I am using TOAD and working in Oracle 10g. Here is my table structure and the query i use to try and get what I am looking for:
There is one extra table but that is only used to link these two tables listed below so i didn't bother posting it.

ITEM_ID 4 NUMBER Y
TX_DATE 2 CHAR (8 Byte) N
TX_ID 1 NUMBER (9) N
TX_TYPE 13 VARCHAR2 (4 Char) N

Need help in Report From SQL Query

Hi All,
I am facing a problem with a report. I need your help.
I am creating a Report From SQL Query (Portal) with some arguments passed at runtime. I am able to view the output, if the query returns few rows ( arount 1000 rows). But for some inputs it needs to generate >15000 records, at this point the page is getting time out (i think!) and showing error page. I am able to execute query from the SQL Plus console ot using TOAD editor. Here the query is not taking more that 2 mins time to show the result.
If i am executing from Portal i observed that, once i give the appropriate input and hit submit button a new oracle process is getting created for the query on UNIX (I am usign "TOP" command to check processes). The browser page will be shown error page after 5 minutes (i am assuming session time out!) , but on the backend the process will be executed for more than 30 mins.
I tried also increase the page time out in httpd.conf, but no use.
The data returned as a result of the query is sized more than 10 MB. Is caching this much data is possible by the browser page? is the returned data is creating any problem here.
Please help me to find appropriate reasone for the failure?

There could be a variety of reasons for the delayed processing of this report. That includes parameter settings for that page, cache settings, network configurations, etc.
- explore best optimization for your query;
- evaluate portal for best performance configuration; you may follow this note (Doc ID: *438794.1* ) for ideas;
- third: for that particular page carrying that report, you can use caching wisely. browser cache is neither decent for large files, nor practical. instead, explore the page cache settings that portal provides.
- also look for various log files (application.log and apache logs) if you are getting any warnings reflecting on some kind of processing halt.
- and last but not the least: if you happen to bring up a portal report with more than 10000 rows for display then think about the usage of the report. Evaluate whether that report is good/useful for anything?

Need help in installation of SQL Developer in Win7

Dear Frens,
I got a task to validate the SQL developer(64 bit version) in Win7 environment. I followed the advice in this form and installed the 64 bit JDK first.
It can be verified:
C:\>java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)
Then SQL developer asked for the path of java.exe for the first time, and after configuring it to the correct path, I found it had problems creating the connection to the database when I tried to click database connection button. Please be noted, I do not have the win admin right for the PC.
The error messages are listed below. Need some help from you guys.

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 connecting a MS Sql Database in CF Administrator

Good morning,
I`m hoping someone out there can help me.
I simply want to add a MS SQL datasource within Coldfusion Administrator.
I have connected to it successfully with Sql Server Management Studio, using Windows Authentication.
I`m assuming I need to use Windows Authentication to connect within Coldfusion Administrator
How do I fill out these fields then:
because I am getting this error:
Connection verification failed for data source: test
java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer JDBC Driver]Error establishing socket. Unknown host: local
The root cause was that: java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer JDBC Driver]Error establishing socket. Unknown host: local
I have also tried it with localhost as opposed to local.
Please help?
Thanks;
Rhonda

I believe you DON'T.
ColdFusion, by default, does not run as any type of user that would work with Windows Authentication. It can be set up to do so, through the windows services panel. You configure the ColdFusion service(s) to "Log On As" some windows domain account with the desired permissions. This is normally done to allow CFML code to access network resources for file operations and the like.
But, I don't know if that is good enough for a connection to a SQL server. I've never had to deal with it myself (I have operations and database administrators types who deal with this for me). But I have read many many times on forums like this that the default security configuration of SQL server does not work with ColdFusion. That one has to set up an alternate configuration in SQL, TCP/IP I think?

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 With Basics of SQL

Hey I'm trying to get a working understanding of some of the basics behind SQL, I've composed a few questions that I think may help me with this. Anyone that can help me with any of them will greatly help me thanks.
1. How to create synonym for tables?
2. How to describe the structure of tables?
3. How to list the contents of tables?
4. How to create a table named with the same structure as another table?
5. How to copy rows with less than a certain criteria in value (e.g. Price<$5.00) into another table?
6. How to change the data type to e.g. NUMBER(6)?
7. How to add a new column named with data type e.g. VARCHAR2(10)?
8. How to change a specific field within a table (e.g. For ORDER_NUMBER 12489, change the C_NUMBER to 315)?
9. How to delete a specific row from a table?
10. How to declare a column as the primary key of a table and call it e.g. PK_something?
11. How to show certain columns when another column is less than a certain criteria in value (e.g. Price<$5.00)?
12. How to show certain columns with another column having a certain item class e.g. HW or AP?
13. How to list certain columns when another column e.g. price is between two values?
14. How to list certain columns when another column e.g. price is negative?
15. How to use the IN operator to find certain columns (e.g. first and last name of customers who are serviced by a certain ID)
16. How to find certain columns when one of the columns begins with a particular letter (e.g. A)
18. How to list the contents of the a table sorted in ascending order of item class and, within each item class, sorted in descending order of e.g. price?
19. How to do a count of column in a table?
20. How to sum a column and make rename is something?
21. How to do a count of a column in a table (without repeats e.g. if a certain number repeats more than once than to only count it once)?
22. How to use a subquery to find certain fields in columns when the another column’s fields values are greater than e.g. its average price?

Anyone that can help me with any of them will greatly help me thanks.To use the terminology you have in those questions, you must already have a basic understanding of SQL, so you have exposed yourself as not being the author of such questions.
Please do not ask homework questions without having at least attempted to answer them yourself first and show where you're struggling.

Need help in framing an SQL query

Hi ,
Requirement is that
Let’s say I have a table say X
I am passing two input params from UI and in DAO i am querying these input prams against the table X(has c1,c2 as columns ) (as it has two columns mapping the input params A,B from UI).
if either one or Both of the input params matches ,only then i should fetch the records accordingly. It's understood that there won't be a scenario that both input params are null from UI.
I have three conditions here,
1.     A match against X, B doesnt Match
2.     B match against X, A doesnt Match
3.     Both A & B match against X
if i use let's say,
SELECT *FROM X WHERE (c1= A OR c2= B) .
•     if A match against X B doesnt Match It is fetching all the records matching A - requirement fullfilled
•     B match against X A doesnt Match It is fetching all the records matching B- requirement fullfilled.
•     Both A & B match against X It is fetching all the records from the table matching the first condition (which here is A) . requirement not fullfilled.
I am thinking of using the following query but I need to frame it in a way that based on ACHK & BCHK we need to add the conditions.
SELECT CASE WHEN C1 = A THEN 0 ELSE 9 END AS ACHK, CASE WHEN C2 = B THEN 0 ELSE 9 END AS BCHK FROM X
Based on ACHK & BCHK append the conditions. i.e.
IF ACHK = 0 AND BCHK = 0 THEN
AND C1 = A AND C2 = B
ELSE
AND (C1 = A OR C2 = B)
Please help.

Would be glad if you can shed some light on role of DENSE_RANK here (ofcourse i did read the forums but i am confused on what basis a row is ranked).Complicated queries and expressions are usually built of smaller, simpler parts. To understand how the big, complicated thing works, look first at the smaller, simpler components of it, and make sure you understand how they work.
In this case, the query is composed of a sub-query and a main query. Start by looking at the sub-query only. Display all rows and all columns of the sub-query.
Break apart the complicated components of that sub-query. Rnk depends on an ORDER BY clause, but the expression used in that ORDER BY clause isn't displayed anywhere. Copy and display just that expression. (I called this case_1_2 in the query below.) Even that may be too complicated to understand, so break it apart. Case_1_2 is formed by adding 2 smaller CASE expressions; in the query below, I displayed each of the in separate columns (case_1 and case_2).
So here's a query you might use to understand and debug the query I posted:

For example, the first 12 rows of output show what we found when we were looking for ('ABC', 10). There were 12 rows in table x that had either ca='ABC' or c2=10 (or both). We used the rnk column to find the best match: lower numbers mean better matches. How did we do that? By using the DENSE_RANK function with a DESCending order by clause, that is, we used <tt> DENSE_RANK () OVER (... ORDER BY exp DESC) </tt>, which means that higher values of exp produce lower values from DENSE_RANK. What is exp? It's the column I called case_1_2. As you can see, when there was a perfect match ('ABC', 10), then case_1_2 had the value 3. Less perfect matches got lower values of case_1_2; for example ('ZZZ', 10) only had 2 in the case_1_2 column, and ('ABC', 5) only had 1. Why did case_1_2 have values of 3, 2 or 1 on those rows? Well, it's the sum of case_1 and case_2, so look at those individual columns, and see how they are computed.

Need help saving image to SQL as BLOB, then sending as email attachment

Hi folks,
These forums have gotten me most of the way through this particular project, but I'm finally stumped...
First, I'll describe exactly what I'm trying to do: the user chooses an image file client side and the server-side code then converts it to binary data and saves it to SQL. Then as a separate step, an email will be sent out with that image file loaded from the DB as an attachment.
So I've actually got most of this working. I'm using the O'Reilly MultipartParser class to pull the file input stream from the Request and insert it into SQL BLOB column ("image" datatype). I can successfully send Text attachments by simply converting the binary data back to a string and then using a subclass of DataSource (ByteArrayDataSource) to feed it to the mail object.
After getting the text documents to work, I then moved on to trying to send images.
I tried to send images using essentially the same technique as sending text. The image file gets saved to SQL the same way and I then convert the binary data back to a string an attach it. The only difference is that I set the content-type to "image/gif".
I didn't really expect this to work, however, I am able to "Preview" very simple Gifs (in XP) that I've attached. I cannot "Open" them, though, and I cannot even "Preview" more complicated Gifs.
So on to my real questions. I didn't really expect that you could simply output binary image data into Text format and simply slap on a ".gif" and expect it to work. Am I right about that? XP's "preview" option seems to read it okay, but I really need to be able to "open" these files.
So basically I need to know what to DO with that binary data in SQL in order to successfully attach it as a true image file. Is this an encoding issue? MIME type?
I didn't want to paste all the code but I'll paste the snippet that deals with the attachment section. If you'd like to see any other parts, please just let me know...
MyBlobObject v_blob = new MyBlobObject(m_cp); // the getBlobStr() method of this object simply grabs the data from SQL as a String
DataSource source = new ByteArrayDataSource(v_blob.getBlobStr(),"application/octet-stream");
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setHeader("content-type","image/gif");
messageBodyPart.setFileName(v_fileName);
...Another interesting thing I'm seeing is that when I view the small Gif as text, I see this:
GIF89a � !� , D ;
While the file I'm getting from SQL as an attachment looks like this:
GIF89a ? !? , D ;
Obviously, the question marks are unknown, but I'm not quite sure why. I outputted the char values as integers and found that the first question mark is 65408 and the second one's value is 65529. Obviously something is getting changed somewhere in the process, but I'm not quite sure how and where.
anyway, thanks in advance for any advice!

Nevermind! Of course, I figured it all out after writing that long post.
I had tried using a byte array instead of the String in the ByteArrayDataSource and it hadn't worked. However once I cleaned up the code a bit I got it working.
This links has it all...
http://www.magelang.com/faq/view.jsp?EID=498439
thanks anyway!

Need help with a Java-SQL connection

My classmates and I created a DesktopFrame. Within it are reports that require a connection to an MS Access Database. When a report in an InternalFrame is opened: the SQL command works, there is a connection, and everything goes well on the first run.
However, when another InternalFrame is opened or when the same InternalFrame is opened the 2nd time, an error occurs. It produces a java.sql.SQLException: General Error.
Can anyone help me? Thanks in advance.

Provide more info, maybe even some code segments. (Not all). May be easier to help
