What is "with" and "Connecty By" in Oracle SQL

Hello All,
I'm Just going through the forum topics, I have seen sql queries starts like "with t as" and at the end it closes like "connect ". I have seen this kind for normal queries also. Please let me know what is the "with" concept and when do we use that?
Thanks in Advance!!!

And in 11gR2 you can combine the two with the new feature Recursive Subquery Refactoring (well sort of, because you don't need the connect by bit)
I'd link to the official docs but they seem to be suffering intermittent issues at the moment so:

My_Total_PR - Number of my child PR accounts which doest not include itself.
Total_PR - Total number of PR accounts in the overall structure
My_Total_NPR - Number of my child NPR accounts which doest not include itself.
Total_NPR - Total number of NPR accounts in the overall structure
*PR stand for payment responsible, for instance the payment responsible for Account 158 is 158 (Paying_Account_ID), so the Total_PR for 158 is 3 (158, 159, 160)
*NPR stand for Non payment responsible, for instance the payment responsible for Account 159 is 158 (Paying_Account_ID), so the Total_NPR for 159 is 1
This is the expected result, Any advice much appreciated. Thanks

CREATE TABLE "SYSTEM"."ACCOUNT" ...
Don't create your own objects in the SYSTEM schema, or any schema that comes with the database. Create a separate schema, and put your objects into it. You'll have fewer security problems, and migrating to a new database will be easier.
Here's one way to can get the aggregates that you want:
WITH     got_descendants          AS
     SELECT     CONNECT_BY_ROOT account_id     AS ancestor_id
     ,     paying_account_id
     ,     LEVEL                    AS lvl
     FROM     account
     CONNECT BY NOCYCLE     PRIOR account_id     = parent_account_id
          AND          account_id          != parent_account_id
SELECT       ancestor_id
,       COUNT (CASE WHEN lvl             > 1
                  AND ancestor_id = paying_account_id THEN 1 END)     AS my_total_pr
,       COUNT (CASE WHEN ancestor_id = paying_account_id THEN 1 END)     AS total_pr
,       COUNT (CASE WHEN lvl             > 1
                  AND ancestor_id != paying_account_id THEN 1 END)     AS my_total_npr
,       COUNT (CASE WHEN ancestor_id != paying_account_id THEN 1 END)     AS total_npr
FROM       got_descendants
GROUP BY ancestor_id
;Output:

    3385217     0     1     0     0This gives you the right numbers, but how can we get them in an order that reflects the hierarchy, with the columns (such as lvl) that are derived from the hierarchy?
One way would be to do two CONNECT BY queries; one without a START WITH clause (like the one above) that gets the aggregates, and the other with a START WITH clause (like your original query), that is in the right order, and has columns such as level_label and level. We could join the result sets and get exactly what we want. I'll leave that as an exercise.
Here's another way, that gets the right results with only one CONNECT BY query:
WITH     got_descendants          AS
     SELECT     CONNECT_BY_ROOT account_id     AS ancestor_id
     ,     paying_account_id

     ,     CONNECT_BY_ISCYCLE          AS cycle
     ,     CASE
              WHEN CONNECT_BY_ROOT account_id
                  = CONNECT_BY_ROOT parent_account_id
              THEN ROWNUM
          END                    AS r_num

     ,     MAX (lvl)   OVER (PARTITION BY account_id)      AS max_lvl
     FROM     got_descendants
SELECT       LPAD ( ' '
            , 2 * (MIN (max_lvl) - 1)
            ) || ancestor_id                         AS level_label

You may not care which of those comes first, but if that's important, explain why those rows need to be in descending order by account_id, while '159 and '160' are in ascending order. You'll need to change the ORDER SIBLINGS BY clause accordingly.

What are the Major and Minor Diffs between oracle,sql server,MSAccess

Hi all,
Can any one explain or send me all the diff between
oracle ,sql server,access..like how much data can each
support,...
Thanks

Dear sir,

Extraction of data from Planning and load it into Oracle/SQL server (RDBMS)

Hi All,
ODI can extract data from Oracle/SQL server RDBMS and load it into Hyperion planning, but I wanted to know if it is possible to extract data from Hyperion Planning through ODI and load it into Oracle or SQL server RDMBS i.e the other way round.
Kindly let me know if that is possible or not,If yes then please let me know what is the exact process to achieve this through ODI.
Thanks & Regrads,
Gurpreet

Yes this can be done. Remember that Planning data is actually stored in Essbase so the Knowledge module you will need to use is LKM Essbase to SQL (DATA)

Issue with Oracle SQL Developer

I use a oracle database for my process (LMS relared stuff)
When i write a query which is expected to pull thousands and thousands of records. Why do i need to keep scrolling down to fetch more records.
Why will it not pull all the records?
I need to keep scrolling down till i get all the records.
Any solution?
(I'm using it for the first time in my life. i'm just 3 day old to this software)
My O/S: Win XP Professional with 1gb of RAM.
Oracle SQL Developer Version: 1.2.1 Build Main-32.13
Is any other information required???

This will be in the next release. However, if you want to put this in now you can make an extension ( there's examples on my blog) and put this chuck of code in:
Connections.getInstance().addConnectionListener(new ConnectionListener() {
               public void connectionAdded(ConnectionEvent evt) {}
               public void connectionClosed(ConnectionEvent evt) {}
               public void connectionModified(ConnectionEvent evt) {}
               public void connectionOpened(ConnectionEvent evt) {
Connection conn = Connections.getInstance().getConnection(evt.getConnectionName());
if (conn instanceof OracleConnection){
((OracleConnection)conn).setDefaultRowPrefetch(DBConfig.getInstance().getInt(DBConfig.ARRAYFETCHSIZE));
               public void connectionRemoved(ConnectionEvent evt) {}
               public void connectionRenamed(ConnectionEvent evt) {}
});

ok, but how i found the listener o the tsnames, because i searching in all disk (c) but i dont found them, or how i can turn on the listener o whe is the directory when i put the files, because the installation dont have the /network/adm for put the files
Edited by: user13373417 on 07-Jul-2010 09:06It appears you don't have a very clear understanding of how the client and the server are configured to communicate with one another.
============
A couple of important points.
First, the listener is a server side only process. It's entire purpose in life is to receive requests for connections to databases and set up those connections. Once the connection is established, the listener is out of the picture. It creates the connection. It doesn't sustain the connection. One listener, running from one oracle home, listening on a single port, will serve multiple database instances of multiple versions running from multiple homes. It is an unnecessary complexity to try to have multiple listeners. That would be like the telephone company building a separate switchboard for each customer.
Second, the tnsnames.ora file is a client side issue. It's purpose is for address resolution - the tns equivalent of the 'hosts' file further down the network stack. The only reason it exists on a host machine is because that machine can also run client processes.
Assume you have the following in your tnsnames.ora:
larry =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = myhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = curley)
)Now, when you issue a connect, say like this:
$> sqlplus scott/tiger@larrytns will look in your tnsnames.ora for an entry called 'larry'. Next, tns sends a request to (PORT = 1521) on (HOST = myhost) using (PROTOCOL = TCP), asking for a connection to (SERVICE_NAME = curley).
Where is (HOST = myhost) on the network? When the request gets passed from tns to the next layer in the network stack, the name 'myhost' will get resolved to an IP address, either via a local 'hosts' file, via DNS, or possibly other less used mechanisms. You can also hard-code the ip address (HOST = 123.456.789.101) in the tnsnames.ora.
Next, the request arrives at port 1521 on myhost. Hopefully, there is a listener on myhost configured to listen on port 1521, and that listener knows about SERVICE_NAME = curley. If so, you'll be connected.
What can go wrong?
First, there may not be an entry for 'larry' in your tnsnames. In that case you get "ORA-12154: TNS:could not resolve the connect identifier specified" No need to go looking for a problem on the host, with the listener, etc. If you can't place a telephone call because you don't know the number (can't find your telephone directory (tnsnames.ora) or can't find the party you are looking for listed in it (no entry for larry)) you don't look for problems at the telephone switchboard.
Maybe the entry for larry was found, but myhost couldn't be resolved to an IP address (say there was no entry for myhost in the local hosts file). This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe there was an entry for myserver in the local hosts file, but it specified a bad IP address. This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe the IP was good, but there is no listener running: "ORA-12541: TNS:no listener"
Maybe the IP was good, there is a listener at myhost, but it is listening on a different port. "ORA-12560: TNS:protocol adapter error"
Maybe the IP was good, there is a listener at myhost, it is listening on the specified port, but doesn't know about SERVICE_NAME = curley. "ORA-12514: TNS:listener does not currently know of service requested in connect descriptor"

Java.sql.SQLException: Internal Error while using oracle.sql.ARRAY.getArray

Hello All,
Here is the issue description. Our application uses Oracle Object Types and LIST. We deployed our application on QA environment which has Oracle 10g. Application runs fine...no issues. Now we moved to UAT. UAT environment is same as QA environment and DBA have created replica of QA database.
Now WAR file which works fine with QA database , somehow doesnt work with UAT database. Application throws following exception when code tries to call getArray() on java.sql.Array.
We tried to point UAT weblogic to QA database and it worked fine.....but when we point UAT weblogic to UAT database , we get following exception. So we know that this is a database issue.
DBA claims that QA env database and UAT env database are same.
Can anybody please tell me what wrong here? What setting is not done on UAT database which is done on QA?

This can happen if you use the oracle.sql.ARRAY class with WebLogic.
WebLogic wraps oracle.sql.ARRAY with its own class (i.e. weblogic.jdbc.wrapper.Array_oracle_sql_ARRAY). The easiest solution is to replace oracle.sql.ARRAY with the JDBC standard java.sql.Array.
<PRE class=jive-pre><CODE class="jive-code jive-java">Object[] items = (Object[])array.getArray();
if (items.length > 0) {
for (int i = 0; i < items.length; i++) {
Object arrayItem = items;
}
}
</CODE></PRE>
The array object is a java.sql.Array. Here no unwrapping of the WebLogic wrapper is needed.
If you absolutely need the oracle.sql.ARRAY class than you must use an unwrap API on the WebLogic wrapper class.
<PRE class=jive-pre><CODE class="jive-code jive-java">if (object instanceof weblogic.jdbc.wrapper.Array)
array = (ARRAY) ( ((weblogic.jdbc.wrapper.Array)object).unwrap(Class.forName("oracle.sql.ARRAY")) );
else
array = (ARRAY) object;
</CODE></PRE>
Here, array is an oracle.sql.ARRAY. Try to see if this <A class=bodylinkwhite href="http://www.software-to-convert.com/3gp-conversion-software/3gp-to-myspace-video-software.html">helps</A>. Good luck.
Thanks for your explanation! It's very valuable, It is exactly what I need, I understand this part.

Unable to connect to Oracle Database using Oracle Sql developer 2.1.1.64

Hi Everyone,
I am searching for some help regarding my problem with Oracle connectivity. I have installed Oracle 11g release 2 on my Windows XP Professional Laptop. For a few days after installation i could connect to the Oracle database with the SYSTEM account using Oracle SQL developer ( installed on the same Laptop) but now i am unable to do so.It gives me this annoying message:
An error was encountered performing the required operation Got a minus one from read call .Vendor code 0
However i am able to connect using Sql Plus by supplying the username SYSTEM and the corresponding password.
My TNSNAMES .ora file is as follows:

I am new to Oracle and so i need someone in this forum who can help me resolve this problem. Also i even tried connecting to the database using Toad 10.5.0.41. It give me the following error:
ORA 12537 : TNS Connection closed
Thanks for your patience and help in advance.

Thanks for your response to my initial post.Do u have any other methods to resolve this?

Unable to display results of multiple query in grid in Oracle SQL Developer

Hi, I am a newbie to this forum and couldn't find the Oracle SQL Developer forum so posting it here.
My question: How to display multiple query results in grid in Oracle SQL Developer.
Example:
select * from Employee;
select * from Department;
- when I select both the queries and hit F5 in Oracle sql developer. By default it displays in output window.
- How to display result of both the queries in Grid.
Any thoughts on this would be really helpful.
Thanks in advance.
Harsh

Hi Harsh,
I'd say that the Results grid is designed to only show the results of 1 query at a time. I don't know/can't see how it would display multiple queries at a time.
I would suggest either joining your tables to create a single query or opening another SQL Worksheet for one of the queries so that you can display the results side-by-side.
Maybe you could explain what you're trying to do. Why are you trying to display multiple results in the same query grid?

Importing oracle.sql.BLOB through SQL Loader

Hello,
Currently the system we have creates .sql files and executes them. This takes a long time, so we're attempting to change to using SQL Loader. The one problem I'm having that I can't seem to fix is finding out how to imitate the behavior of this SQL statement through SQL Loader:
INSERT INTO KRSB_QRTZ_BLOB_TRIGGERS (BLOB_DATA,TRIGGER_GROUP,TRIGGER_NAME)
VALUES (oracle.sql.BLOB@515263,'KCB-Delivery','PeriodicMessageProcessingTrigger')
I tried creating a lobfile and placing the text oracle.sql.BLOB@515263 within it this way
INTO TABLE KRSB_QRTZ_BLOB_TRIGGERS
WHEN tablename = 'KRSB_QRTZ_BLOB_TRIGGERS'
FIELDS TERMINATED BY ',' ENCLOSED BY '##'
TRAILING NULLCOLS
tablename FILLER POSITION(1),
TRIGGER_NAME CHAR(80),
TRIGGER_GROUP CHAR(80),
ext_fname FILLER,
BLOB_DATA LOBFILE(ext_fname) TERMINATED BY EOF
However, as expected, it merely loaded the text "oracle.sql.BLOB@515263" into the database. So does anyone have any ideas of how to imitate that insert statement through SQL Loader? The only information I have available is the string "oracle.sql.BLOB@515263", no other files or anything to aid with actually getting the binary data.
When the .sql file is run with that insert statement in it, a 1.2kb BLOB is inserted into the database versus a 22 byte BLOB that contains nothing useful when done through SQL Loader.
Alex

My preference is DBMS_LOB.LOADFROMFILE

did you try it?

Problem with java.sql.Clob and oracle.sql.CLOB

Hi,
I am using oracle9i and SAP web application server. I am getClob method and storing that in java.sql.Clob and using the getClass().getName() I am getting the class name as oracle.sql.CLOB. But when I am trying to cast this to oracle.sql.CLOB i am getting ClassCastException. The code is given below
java.sql.Clob lOracleClob = lResultSet.getClob(lColIndex + 1);
lPrintWriter = new PrintWriter(new BufferedWriter (((oracle.sql.CLOB) lOracleClob).getCharacterOutputStream()));
lResourceStatus = true;
can anybody please tell me the what is the problem with this and solution.
thanks,
Ashok.

Hi Ashok
You can get a "ClassCastException" when the JVM doesn't have access to the specific class (in your case, "oracle.sql.CLOB").
Just check your classpath and see if you are referring to the correct jar files.

Installing PHP OCI8 extension on SLES 11 with PHP 5.6.3 Oracle Instantclient 12.1 and APACHE2

I am attempting to install the OCI8 extension. The OCI8 extension version is oci-2.0.8.
The configure script to install is "./configure --with-oci8=instantclient,/usr/lib/oracle/12.1/client64/lib".
The configure runs ok. But when I run make test, it fails on every single oci test.
The install directory of instantclient is "/usr/lib/oracle/12.1/client64"
I have also declared $ORACLE_HOME and $LD_LIBRARY_PATH, and also declared instantclient in the path.
I have also installed Perl on the server and that runs script's to update the remote oracle database. So the issue is not with instantclient.
I am not sure what to do. Have spent 2 days on this issue. Any help will be greatly appreciated.
Thanks.

How and where did you set the environment variables?
How are you running the tests?
What errors are you seeing?

What is the best source to learn and advice to get Oracle 12c (OCA) certificate???

Hi there,
I hope all are running good.
Actually, I'm a new in a Oracle career but I know all concepts of Databases and SQL.
I'm planning to take a Oracle 12c (1Z0-061) (SQL Fundamentals) exam to achieve 12c OCA certificate but I'm bit confused in what source is best to learn it by self and what are tips to pass those all exam to lead me OCA certificate. Please, kindly provide your valuable opinions. Look forward to hearing your replies.
Thanks

The Oracle Press exam guide for 1Z0-061 is written, though of course there is all sorts of production stuff still to go. The 1Z0-062 guide (a lot longer!) is done except for the last two chapters. So both should be out in the near future. I know this because my buddy Roopesh is writing 1Z0-061, and I'm writing 1Z0-062. Bob Bryla's 1Z0-063 guide is bit later, the exam isn't in beta yet.
As Philippe says, the OCA is not simple this time. Of course I can't reveal the exam content, but I think I can say that Oracle Uni is raising the standard with 12c .
