hierarchical sql (part 2) - error: duplicate rows

Following up on my previous question:

This hierarchical query has the duplicate in the result set rows:

Select record_id, parentid, name from my_table
connect by parentid = prior record_id
siblings arrested by name;

Thanks for help.

----------

My table has five columns:

rank (number)
score (number)
name (varchar)
record_id (number)
ParentId (number)

A parentid is a record_id at a higher level in the hierarchy.
A parentid is a record_id at a higher level in the hierarchy.
Rank and Score are used to control (tri) each level of the hierarchy.

The data looks like this:

grade - score - name - record_id - parentid

--------------------------------------------------------------------------------
1 - 1 - name1 - 101-0
1 - 2 - name2 - 102-0
1 - 3 - name3 - 103-0
2 - 1 - name4 - 104-101
2 - 2 - name5 - 105-101
2 - 1 - name6 - 106-102
2 - 2 - Marque7 - 107-102
2 - 1 - name8 - 108-103
2 - 2 - name9 - 109-103

Desired results set:

grade - score - name - record_id - parentid
--------------------------------------------------------------------------------
1 - 1 - name1 - 101-0
2 - 1 - name4 - 104-101
2 - 2 - name5 - 105-101
1 - 1 - name2 - 102-0
2 - 1 - name6 - 106-102
2 - 2 - Marque7 - 107-102
1 - 1 - name3 - 103-0
2 - 1 - name8 - 108-103
2 - 2 - name9 - 109-103

PL/SQL: Statement ignored SQL error (SELECTing row, expression arithmetic/s)

Quick question, on the execution of the query of the ff, I do
Select a.column, sum (decode(a.column,'string',1,'etc...')
But when I include a func or procedure, it won't allow me too and that he would give a PL/SQL: SQL statement ignored error and it will compile only if I remove the first a.column as follows
Select sum (decode(a.column,'string',1,'etc...')
Why is it so? And how should it be rewritten to include the select a.column?

Procedure to update duplicate rows

In a table, I have a few duplicate lines

I can get it through this query: select PARTY_ID from the XXWFS_CUSTOMER_EXT by PARTY_ID group saw County (PARTY_ID) > 1;

Now for the record I got for each duplicate row, I want to update the second row with a specific value... so the duplicate rows that no longer exist

Ex: I went 12 ID, 14, 16, 18 twice each

Now that 12 is twice... I want to update in the second row of 12 with a value of x is the same for other values like 14.16, etc.

How can I write a procedure for this

Thank you

Hello

In my view, using the single UPDATE statement, we can do.

Please see the example below. Please use it according to your requirement.

SQL> create table test_emp (empno number,ename varchar2(40));

Table created

SQL> insert into test_emp values (1,'SURI');

1 row inserted

SQL> insert into test_emp values (1,'SURI');

SQL> insert into test_emp values (2,'SRINU');

1 row inserted

SQL> insert into test_emp values (2,'SRINU');

1 row inserted

SQL> SELECT *
  2  FROM test_emp;

     EMPNO ENAME
---------- ----------------------------------------
         1 SURI
         1 SURI

SQL> UPDATE test_emp t2

  3  WHERE t2.rowid > (SELECT min(t1.rowid)
  4                  FROM test_emp t1
  5                  WHERE t1.ename=t2.ename);

2 rows updated

SQL> SELECT *

         1 SURI
         1 X
         2 SRINU
         2 X

According to the structure of your table

UPDATE XXWFS_CUSTOMER_EXT x1
SET x1.party_id = 
WHERE x1.part_id = 12
AND x1.rowid > (SELECT min(rowid)
                FROM XXWFS_CUSTOMER_EXT x2
                WHERE x2.party_id = x1.party_id);

error "duplicate definition of the function.

How can I change the code below to avoid an error?
It gives me an error "duplicate function definition. Of course, I learn fast enough and little error.
thumpy.addEventListerner (MouseEvent.CLICK, onClick);
function onClick(evt:MouseEvent):void {}
var url: String = " " http://www.thumpersf.com '; '.
var req:URLRequest = new URLRequest (url);
navigateToURL (req, "_blank");
}

You are right about the two lines is necessary. One involves the transfer of the event listener with the identification of the function of Manager in it:

humpy.addEventListener (MouseEvent.CLICK, onClick);

and the other is the actual event handler function

function onClick (...

The duplication error will arise when you have two functions sharing the same name...

function onClick (...

function onClick (...

Unfortunately I do not see the history of the display when writing, so I don't know if it is possible that some other functions were duplicated, rather than that which is currently focused on until now.

To answer your original question and rule the entrance/exit or not that code is the problem, change the code as follows:

thumpy.addEventListener (MouseEvent.CLICK, clickThumpy);

function clickThumpy(evt:MouseEvent):void {}

var url: String = ""http://www.thumpersf.com "; "

var req:URLRequest = new URLRequest (url);

navigateToURL (req, "_blank");

}

(Don't sweat short-circuit the code...) If you're new to AS3, it is better to learn it realizing that there are three distinct parts to bond a URL did you watch... you can drive with one hand after completing some experiments using two)

Sol.beach thanks for the reply, I'm able to correct the problem. In fact the PATH variable has put in .profile of export PATH = $PATH: $ORACLE_HOME/bin and the value is lower.

-bash-3, $ 2 echo $PATH

/Apps/Oracle/product/9.2.0.8.2009Q4/bin:/usr/ccs/bin:/usr/sbin:/usr/bin:/bin:.:/ bin:/opt/bin:usr/CSS/bin:/usr/ucb:/usr/local/bin:/apps/Oracle/product/11.2.0.3.2014Q3/bin

I changed as export PATH = $ORACLE_HOME/bin: $PATH and now it works fine. It seems to be a problem with the old Oracle Home, also present in the PATH variable before the bin to the current address of Oracle Home Directory.

-bash-3, $ 2 echo $PATH

/Apps/Oracle/product/11.2.0.3.2014Q3/bin:/apps/Oracle/product/9.2.0.8.2009Q4/bin:/usr/ccs/bin:/usr/sbin:/usr/bin:/bin:.:/ bin: / opt/bin: css/usr/bin: / usr/ucb: / usr/local/bin

Hello

Display online ensures that only unique combinations (id, name, first name) table will be used, but the main result set does not include id, so there is no guarantee that the production lines of the main request will be unique.

Some results you get, you should get the same results if you create a view or not. As Paul says, post a test script complete that people who want to help you can to recreate the problem and test their ideas.

How to remove duplicate rows (not exactly duplicate)
Hi I have lines like this in a table emp

ENO ename age
1 25
26 2
3 25
4 26

I don't have repititve enames... (here in this example: A).

If I find something like that I should keep the first line and delete all other lines.

How can I do this?

as unique empowerment of ename... (except for this)
Hi Renon,
There are different ways could remove duplicate rows, but Franks solution seems good.
With the help of ID you can get good results in the largest data sets. If you want Nwe minutes remain in the database and all others to delete then make use of eno and not rowid.
```
DELETE FROM emp y
WHERE       eno != (SELECT   Min(eno)
                    FROM     emp x
                    WHERE    x.NAME = y.NAME
                    GROUP BY NAME)

The secondary database of Data-Guard is supposed to have the same as the primary database db_name?

Help, please...

Hello;

I agree with Hemant. Looks like you have skipped before too much too quickly without doing the reading.

Here are my notes for duplication on the same host, but this is not a duplication of Eve. However it should give you an idea and not on a single host.

need to remove duplicate rows from a table

Hi gurus,
I'm using oracle 11.2.0.3.

ATTRIB_17 NUMBER (22.7)
DATE OF ATTRIB_26
ATTRIB_02 VARCHAR2 (100 CHAR)
PROCESS_TIMESTAMP TIMESTAMP (6);
now, when I give the command below, it gives error as someone has disabled the constraint accidentally.
change the table s_evt_act_x S_EVT_ACT_X_P1 enable constraint;
Error from line 3 in order:
change the constraint of table s_evt_act_x activate S_EVT_ACT_X_P1
Error report:

the database error duplicate from one server to another server
Hello

I'm practicing duplicate database to a single database server to another server. Path material and pilot on 2 machines is the same. Here are my steps:
-Clone site:
1 change the listener.ora with content:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = CIP)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain) (PORT = 1521))
)
)

ADR_BASE_LISTENER = / u01/app/oracle
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = orcl)
)
)
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER = WE
2. stop and start receiving once again, show message as:
Service "orcl" has 1 instance (s).
Instance "orcl", status UNKNOWN, has 1 operation for this service...

The command completed successfully
3. create pfile from spfile file.
4. stop and startup nomount with pfile is new pfile create in step 3.
--------------------------------------- Source site
1 edit tnsnames.ora with content like:
VVCOREDB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain) (PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = vvcoredb)
)
)

ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = 10.254.1.235) (PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
2 run the command of rman like these:
RMAN > Connect target sys@vvcoredb
RMAN > target password database:
RMAN > Connect auxiliary sys@orcl
RMAN > database auxiliary password:
RMAN > DUPLICATE TARGET DATABASE for database orcl active spfile nofilenamecheck.

Then the result show below:

Please suggest me I miss some steps when trying to duplicate database?

Any suggestions are welcome.

Thanks in advance!

P/s: sorry for my bad English.
This error is because the location of the controlfile specified in your spfile is not present on your server to clone. Change the location of the parameter cntrolfile in spfil or create the same location on the server.

hierarchical SQL

Hello

I'm looking for help with a hierarchical query.

My table has five columns:

rank (number)
score (number)
name (varchar)
record_id (number)
ParentId (number)

A parentid is a record_id at a higher level in the hierarchy.
Rank and Score are used to control (tri) each level of the hierarchy.

The data looks like this:

grade - score - name - record_id - parentid
----------------------------------------------------------
1 - 1 - name1 - 101-0
1 - 2 - name2 - 102-0
1 - 3 - name3 - 103-0
2 - 1 - name4 - 104-101
2 - 2 - name5 - 105-101
2 - 1 - name6 - 106-102
2 - 2 - Marque7 - 107-102
2 - 1 - name8 - 108-103
2 - 2 - name9 - 109-103

I would like to request to view the data in the following order:

grade - score - name - record_id - parentid
----------------------------------------------------------
1 - 1 - name1 - 101-0
2 - 1 - name4 - 104-101
2 - 2 - name5 - 105-101
1 - 1 - name2 - 102-0
2 - 1 - name6 - 106-102
2 - 2 - Marque7 - 107-102
1 - 1 - name3 - 103-0
2 - 1 - name8 - 108-103
2 - 2 - name9 - 109-103

The simple query to get this sequence of result set is adequate. No need to fill or other characteristics.

Thank you.

All the columns in your sample have same agenda, so it is not possible to tell which column you want to sisters of the order. I'll assume by its name:

select  *
  from  your_table
  start with parentid = 0
  connect by parentid = prior record_id
  order siblings by name
/

For example:

with sample_table as (
                      select 1 grade,1 score,'name1' name,101 record_id,0 parentid from dual union all
                      select 1,2,'name2',102,0 from dual union all
                      select 1,3,'name3',103,0 from dual union all
                      select 2,1,'name4',104,101 from dual union all
                      select 2,2,'name5',105,101 from dual union all
                      select 2,1,'name6',106,102 from dual union all
                      select 2,2,'name7',107,102 from dual union all
                      select 2,1,'name8',108,103 from dual union all
                      select 2,2,'name9',109,103 from dual
                     )
select  *
  from  sample_table
  start with parentid = 0
  connect by parentid = prior record_id
  order siblings by name
/

     GRADE      SCORE NAME   RECORD_ID   PARENTID
---------- ---------- ----- ---------- ----------
         1          1 name1        101          0
         2          1 name4        104        101
         2          2 name5        105        101
         1          2 name2        102          0
         2          1 name6        106        102
         2          2 name7        107        102
         1          3 name3        103          0
         2          1 name8        108        103
         2          2 name9        109        103
