• ORA-01436: CONNECT loop in the user data

  Hello
  
  I have a simple bit of SQL out details on HR supervisor strings in Oracle EBS:
  

  SELECT     LPAD(' ', (LEVEL - 1) * 10, ' ') || person_id level_label
           , LEVEL
           , description
        FROM applsys.fnd_user u
           , hr.per_all_assignments_f h
       WHERE u.employee_id = h.person_id
  START WITH SYSDATE BETWEEN effective_start_date AND effective_end_date
         AND person_id = :personid
  CONNECT BY PRIOR person_id = supervisor_id
         AND SYSDATE BETWEEN effective_start_date AND effective_end_date

  It will return data normally without problems - e.g. data dummy below - looks very good. The names and made up person_ids.

  However, if I try for an another person_id, for which a user receives an error in one part of the Oracle EBS, I get this error:
  
  ORA-01436: CONNECT loop in the user data
  
  I'm guessing there is a loop of supervisor happening somewhere, but I don't know how to determine where it might happen.
  
  I was wondering if there is any way I can change the SQL code to be able to work out where the loop can be, as there are about 50 people involved in Ministry to this user and I have been through all their records and can not see a loop to look through the Oracle HR screens.
  
  I know it's a 'big ask' to ask a vague question about some oracle SQL, so apologies for that.
  
  Any advice much appreciated.
  
  Thank you

  Hello

  To see loops, do something like this:

  SELECT     SYS_CONNECT_BY_PATH (person_id, '/')     AS path
  FROM      applsys.fnd_user           u
  ,      hr.per_all_assignments_f      h
  WHERE      u.employee_id           = h.person_id
  AND     CONNECT_BY_ISCYCLE     = 1
  CONNECT BY NOCYCLE     PRIOR person_id = supervisor_id
       AND           SYSDATE      BETWEEN     effective_start_date
                           AND      effective_end_date
  ;
  

  If you would care to post CREATE TABLE and instructions INSERT for some samples, so I could test it.

  Note there is no START WITH clause.

  If, for example, Jones is the architect of Scott, Scott is the main contractor of Adams and Adams is the architect of Jones (much to other lines is not involved in a loop), then displays 3 rows of output, such as

  PATH
  ---------------------
  Jones/Scott/Adams
  Scott/Adams/Jones
  Adams/Jones/Scott
  

  Moreover, all the same CONNECT BY queries on these tables can be a lot faster if you've made the join and date filtering in a separate subquery first:

  WITH     combined_data     AS
  (
       SELECT     person_id, supervisor_id
       FROM      applsys.fnd_user           u
       ,      hr.per_all_assignments_f      h
       WHERE      u.employee_id      = h.person_id
       AND     SYSDATE      BETWEEN     effective_start_date
                      AND      effective_end_date
  )
  SELECT     SYS_CONNECT_BY_PATH (person_id, '/')     AS path
  FROM     combined_data
  WHERE     CONNECT_BY_ISCYCLE     = 1
  CONNECT BY NOCYCLE     PRIOR person_id = supervisor_id
  ;
  

• ORA-01436: CONNECT loop in the user data when the delimited string splitting by the

  I'm trying to split a string into records. The values are three characters more '-' with a limit of 12 values. The values themselves are a combination of two data, the first being two characters, a.

  The following example translates: ORA-01436: CONNECT BY a loop in the user data

  WITH
      Data(Code, Datum)
  AS
      (
       SELECT 'VGCU3VM', '00V-YYG-BVC-PIU-DV3-EVV-TVM-' FROM Dual UNION ALL
       SELECT 'VGAU3VM', '00V-YYG-BVA-PIU-DV3-EVV-TVM-' FROM Dual UNION ALL
       SELECT 'VGLN3CM', '00V-YYG-BVL-PIN-DV3-EVC-TVM-' FROM Dual UNION ALL
       SELECT 'VGLT3PM', '00V-YYG-BVL-PIT-DV3-EVP-TVM-' FROM Dual UNION ALL
       SELECT 'VGAT3RA', '00V-YYG-BVA-PIT-DV3-EVR-TVA-' FROM Dual
      )
  SELECT
      Datum,
      LEVEL,
      SUBSTR(Datum, ((LEVEL - 1) * 4) + 1, 2),
      SUBSTR(Datum, ((LEVEL - 1) * 4) + 3, 1)
  FROM
      Data
  CONNECT BY
      Code    = PRIOR Code
      AND    LEVEL    <= LENGTH(Datum) / 4;
  
  

  Remove the 'Code = Code PREREQUISITE"clause, to avoid the error, but too many records are returned, because nothing is to limit the records in their own groups.

  The following works:

  WITH
      Data(Code, Datum)
  AS
      (
       SELECT 'VGCU3VM', '00V-YYG-BVC-PIU-DV3-EVV-TVM-' FROM Dual UNION ALL
       SELECT 'VGAU3VM', '00V-YYG-BVA-PIU-DV3-EVV-TVM-' FROM Dual UNION ALL
       SELECT 'VGLN3CM', '00V-YYG-BVL-PIN-DV3-EVC-TVM-' FROM Dual UNION ALL
       SELECT 'VGLT3PM', '00V-YYG-BVL-PIT-DV3-EVP-TVM-' FROM Dual UNION ALL
       SELECT 'VGAT3RA', '00V-YYG-BVA-PIT-DV3-EVR-TVA-' FROM Dual
      )
  SELECT
      Datum,
      SUBSTR(Datum, ((Some.Num - 1) * 4) + 1, 2) A,
      SUBSTR(Datum, ((Some.Num - 1) * 4) + 3, 1) B
  FROM
      Data,
      (SELECT LEVEL Num FROM Dual CONNECT BY LEVEL <= 12) Some
  WHERE
      SUBSTR(Datum, ((Some.Num - 1) * 4) + 1, 2) IS NOT NULL;
  
  

  What causes ORA-01436?

  Hello

  Depending on your version, you can add another condition to your CONNECT BY clause.

  It works in Oracle 11.2.0.3.0:

  SELECT

  Point of reference,

  LEVEL,

  SUBSTR (Datum, ((LEVEL-1) * 4) + 1, 2),

  SUBSTR (Datum, ((LEVEL-1) * 4) + 3, 1)

  Of

  Data

  CONNECT

  Code = Code PRIOR

  AND LEVEL<= length(datum)="">

  AND PRIOR SYS_GUID () IS NOT NULL-* ADDED *.

  ;

  Thanks for the display of the data of the sample; This is really useful!

  In addition, relational databases are designed to have 1 piece of information in each column of each row, not a list delimited by up to 12 points.  It is so basic to the design of database he called the first normal form.  You're going to solve a lot of problems even before they occur if you paste to first normal form and change the table structure to resemble the result set of this query.  (Maybe that's exactly why you're doing this query.)

• ORA-01436: CONNECT loop in the user data, but CONNECT_BY_ISCYCLE is equal to ZERO all the

  Hello
  
  When I run query below, it always throws the below error:

  SELECT connect_by_root code AS code_root,
      CODE,
      CODE_DESC,
      UP_CODE 
    FROM DI_CODE_LEVEL
    WHERE TYPE_CODE='SP'
      CONNECT BY PRIOR CODE=UP_CODE;
  
  ORA-01436: CONNECT BY loop in user data
  01436. 00000 -  "CONNECT BY loop in user data"

  But when I use NOCLYCLE and CONNECT_BY_ISCYCLE to see which line is in question.
  It shows nothing, which means CONNECT_BY_ISCYCLE = ZERO for all rows.

  select * from (
      SELECT connect_by_root code AS code_root,
          CODE,
          CODE_DESC,
          UP_CODE ,
          CONNECT_BY_ISCYCLE AS ISCYCLE
        FROM DI_CODE_LEVEL
        WHERE TYPE_CODE='SP'
          CONNECT BY NOCYCLE PRIOR CODE=UP_CODE
      ) 
  where ISCYCLE>0;

  Is there another reason that sql would lift ORA-01436?
  If there is a loop, then will the combination of NOCYCLE, CONNECT_BY_ISCYCLE will show?
  
  Thank you

  Hello

  Apparently, one or more of the "SP" lines are at the origin of the problem.
  The WHERE clause is applied after the CONNECT BY is finished, saying:

  select * from (
      SELECT connect_by_root code AS code_root,
          CODE,
          CODE_DESC,
          UP_CODE ,
          CONNECT_BY_ISCYCLE AS ISCYCLE
        FROM DI_CODE_LEVEL
        WHERE TYPE_CODE='SP'
          CONNECT BY NOCYCLE PRIOR CODE=UP_CODE
      )
  where ISCYCLE>0;
  

  is equivalent to

  select * from (
      SELECT connect_by_root code AS code_root,
          CODE,
          CODE_DESC,
          UP_CODE ,
          CONNECT_BY_ISCYCLE AS ISCYCLE
        FROM DI_CODE_LEVEL
          CONNECT BY NOCYCLE PRIOR CODE=UP_CODE
      )
  WHERE    TYPE_CODE = 'SP'
  AND     ISCYCLE   > 0;
  

  To see where the loop occurs, you must include the lines where type_code = "SP".

  When you debug "ORA-01436: CONNECT IN a loop in the user data ', view SYS_CONNECT_BY_PATH (uk,...), where the United Kingdom is a unique key. That will tell you much more than just the root information. You might want this:

  SELECT  connect_by_root code                AS code_root,
          CODE,
          CODE_DESC,
          UP_CODE
  ,     SYS_CONNECCT_BY_PATH (code, '/')     AS path          -- For debugging
  ,       CONNECT_BY_ISCYCLE                AS ISCYCLE     -- For debugging
  FROM      DI_CODE_LEVEL
  -- WHERE TYPE_CODE = 'SP'     -- Commented out for debugging
  where      ISCYCLE > 0          -- For debugging
  CONNECT BY NOCYCLE      PRIOR CODE = UP_CODE
  

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements), and the results you want from this data.
  Explain how you get these results from these data.
  Always tell what version of Oracle you are using.

• Question about creating report guests editor BI when it connects directly to the database?

  Hello

  I create a report of BI Publisher using direct SQL server database. JDBC connection is created, then datamodel and report.

  The report is parameterized. Now I have attached the dashboard report. But now the settings are not filling. So I intend to create guests, but it is the search for field. But I don't use of RPD. So, how can I create guests when we creating BI publisher report connecting directly with the database? Please let me know.

• Is there a way to change the connection string to the database by using the command line on the virtual machine?

  Hi, I use 1.5 space Horizon

  can someone help me by telling me where I can change the connection string for the database on the virtual machine itself.

  I was away, and our stuff has been migrated databases to another server. Now my horizon does not connect because it can not find the database. I can either on the hwconfigurator.xxx.com.

  Thank you

  What do you see when you go to https://hwconfigurator.xxx.com?

  You can try to change this property in /usr/local/horizon/conf/runtime-config.properties on your service - will (s) and the server restart of tc by using the command "/etc/init.d/horizon-frontend restart".

  PER person = person PREREQUISITE

  -Request-

  works very well with the sample data, but the problem is when executed with actual table that has 35K record...

  Cause: The condition specified in a CONNECT BY clause caused a loop in the application, where the next record to be selected is a descendant of itself. When this happens, it may be no end to the query.

  Action: Check the CONNECT BY clause and remove the circular reference.

  Thank you

  Hello

  CONNECT_BY_ISCYCLE is a pseudo-column that you can use in a query of CONNECTION BY NOCYCLE.  It is separated from the CONNECT BY clause.

  Try this:

  Select code, "BREAKS", person

  , SYS_CONNECT_BY_PATH (old_id, "/") AS path

  from table_x

  where CONNECT_BY_ISCYCLE = 1

  Start by old_id not in)

  Select new_id

  from table_x

  )

  CONNECT BY NOCYCLE Old_id = new_id PRIOR

  AND code = code PRIOR

  AND 'CASE' = 'BOX' PRIOR

  PER person = person PREREQUISITE

  ;

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and also publish outcomes from these data.
  Explain, using specific examples, how you get these results from these data.
  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

• when insufficient privileges connect you to the database as sysdba

  I installed a vision with Oracle EBS R12 database. I need to connect to the database as sysdba to unlock the system account. but when I ran command sqlplus / as sysdba, I will this error "ORA-01031: insufficient privileges".
  I sought an answer in the internet, most answer said that it requires the user to linux to be in the dba group. in my config.c file I have this definiation "#define SS_DBA_GRP 'Oracle'. This group "Oracle" is my dba group. and I also checked my current user id (Oracle username is too) and the group, I got:
  [Oracle@linux admin] $id Oracle
  UID = 500 (Oracle) gid = 500 (Oracle) groups = 500 (Oracle)
  all above looks them good to me. I also added authentication_services to sqlnet.ora like this: sqlnet. authentication_services = (All). but I still have the same error. Can someone tell me what is the problem?
  Or y at - it another way to unlock the account system?

• Connection problem with the database, the closure of Flex Builder

  Hello

  I developed a web page that connects to a database, reads data and it shows on the screen. I use HTTPService to connect to a php server that supports MySQL data. Everything is OK when I run the Flex Builder web page, but when I run the page doing double click on the file released .html the connection fails and the program generates this error:

  Does anyone know how can I use the web page without using Flex Builder?

  More information:

  I use Flex Builder 3 to the development of the web page and WampServer 2.0 for the connection with the database.

  Thank you

  Hi Onditz,

  Previously, I also faced the same problem when working with Php as the Backend, the problem is that Flex does not call your PHP page

  It is the way I solved it to export your Flex Project at Flex Release Build.

  Right click on the export of project---> Flex project---> Release Build---> copy all the files on your server where all of your PHP files are and then call the application from the browser

• Switch the database 10g from Windows to Linux (new server)

  Hi people,
  
  I'm still new here and I'm working on a project. I'm trying to move a database 10 g of Windows on a new server with Linux 5. Please what are the steps I need to take?
  
  * The present Server (Windows 7) is in noarchivelog mode
  * There is practically no link between this 2 servers
  * This is a development environment, and so I have a lot of time to experiment.
  
  Thank you!

  Hello
  DataPump (expdp/impdp) is the way to go. expdp create a 'logic' of the database dump - create some think it's just a series of statements and insert statements written in a file. This file is generic and can be used on any platform. If your shipping it a long way (not sure how far Virginia is you another site) you can zip it before sending it. At the other end you just need to create a database of "shell" - that is a very basic database which you are then going to create all objects (maybe version different oracle - with some restrictions). Then use impdp to transfer the file and create everything.

  See you soon,.

• Oracle: Connect loop in the user data

  I understand when a loop can occur in Oracle. In principle that it is said if a recording is both parent to another node and at the same time he was a child to him, then it may go into a loop.

  But I can't get why my this particular query is running in a loop.

  SELECT Empno, Ename, Job FROM Emp START WITH Empno = 7839 CONNECT BY PRIOR Job='PRESIDENT'

  Can someone please explain to me how these data can result in a loop. I did a CONNECT_BY_ISCYCLE check and found that the closure of the case is KING (Chairman). But I still don't understand how can be possible, that the KING is the President and I do not see anything in which it becomes child and parent to any record in the table.

  Please explain to me, why is it a mistake and where is the loop?

  Thanks in advance.

  Maybe if I pull on the hierarchy of your query, you will see what he is doing...

  PRESIDENT OF KING 7839<-- start="">

  PRESIDENT OF KING 7839<-- prior="" job='PRESIDENT'>

  PRESIDENT OF KING 7839<-- prior="" job='PRESIDENT'>

  .. etc.

  .. etc.

  ANALYST SCOTT 7788<-- prior="" job='PRESIDENT'>

  7902 FORD ANALYST<-- prior="" job='PRESIDENT'>

  7369 SMITH CLERK<-- prior="" job='PRESIDENT'>

  7934 MILLER CLERK<-- prior="" job='PRESIDENT'>

  7900 JAMES CLERK<-- prior="" job='PRESIDENT'>

  7521 WARD SALESMAN<-- prior="" job='PRESIDENT'>

  7654 MARTIN SALESMAN<-- prior="" job='PRESIDENT'>

  7844 TURNER SELLER<-- prior="" job='PRESIDENT'>

  Thus, in the first level of the hierarchy is your record START you WITH.

  When all folders are examined, the test of the PREREQUISITE WORK examines the top level folder, determines that he was the PRESIDENT and therefore each record matches this condition.

  Then, each of these folders are evaluated to determine the child records.  At this second level, only KING's post of PRESIDENT, he is the one who would have no record of the child and this WORK PRECONDITION = PRESIDENT will be valid for all records under the 2 KING level.

  This model keeps occurring under each folder KING indefinitely.
