• Binds a parameter in WHERE clause throws error (ORA-00920)

  Good day to you all.  Hope everything goes well.

  Ok.  Here's the deal.  I am trying to bind a parameter in a where clause clause, but I continue to get the error invalid relational operator (ORA-00920).  It seems as if Oracle is looking for a correct syntax before you pass the variable (bind value).

  For example:

  SELECT LAST_NAME, FIRST_NAME FROM MYTABLE
  WHERE OBSOLETE IS NULL
  and :P_MY_BIND_VALUE
  

  What is the right way to get around this?

  Thanks for all your help!

  Thank you for the reply.

  I use simple SQL.  The variable binding will be used in the APEX and an item that is based on a LOV with where condition stored there.  Make sense?

  Logic you want... doesn't have a sense of how you try to do.

  Bind variables are for the passage of the 'values' to a question, only not for the passage of the SQL statements or sections of objects such as the names of tables etc.  It is not a substitution string such as the use of '&' in SQL * more and should not be treated this way.

  If you could provide more details on exactly what you're trying to do (some data would help) then perhaps we could tell how best to go about this.

• Implementation of subqueries in the WHERE clause

  Hi all

  First of all, here are the technical info:

  Oracle JDeveloper 12 c 12.1.3.0.0

  Studio Edition Version 12.1.3.0.0

  Build JDEVADF_12.1.3.0.0_GENERIC_140521.1008.S

  Version of the component

  ========= =======

  Oracle IDE 12.1.3.0.41.140521.1008

  Java (TM) Platform 1.7.0_51

  Support versioning 12.1.3.0.41.140521.1008

  Secondly, the issue I'm facing is I'm trying to implement a query with three sous-sélections them in the (see image below) WHERE clause. I don't know what is the best way to implement something like this.

  I have implemented this by creating a display object and add a view criteria. I put the whole SQL fragment in the view as a literal value criteria. Is there a better (or best?) approach to implement something like this?

  This implementation is a problem is because as well as query tests out fine when I click on explain Plan even recognized that there is no bind variables in subqueries and allows me to.

  When I run this test by the tester of AM, that it fails to recognize and define the binding (projCategory) variable that appears only in subqueries. All your comments and/or help is very appreciated.

  

  Thank you

  Vladimir, there is something wrong in the view Definition of criteria dialog box. The button "explain plan...". "running the whole statement generated (as a string) and returns the result. The entire statement is valid and returns the correct result. However, the view criteria, when it is running in the application work differently. Here the literal that you entered is not passed as a string, but the framework does something internally with her (it is necessary to do things as in the research of memory and other things). If you run the criteria to view in the app Tester I get

  SQL error in the preparation of the statement.  Instruction: SELECT Employees.EMPLOYEE_ID, Employees.FIRST_NAME, Employees.LAST_NAME, Employees.EMAIL, Employees.PHONE_NUMBER, Employees.HIRE_DATE, Employees.JOB_ID, Employees.SALARY, Employees.COMMISSION_PCT, Employees.MANAGER_ID, Employees.DEPARTMENT_ID from employees WHERE (((Employees.SALARY< :vc_temp_1="" )="" )="" )="" ):="" ora-01722:="" invalid="">

  Accordingly, for the display criteria

  employes.salaire< (select="" max(e2.salary)="" from="" employees="" e2="" where="" e2.department_id="">

  As you can see the literal is passed as: vc_temp_1 and my binding variable is not visible at all. You can open an SR and ask for the support of working on it. I guess that they do not see a bug here as help for the dialog box says:

  Literal

  Select when you want to provide a value for the attribute, or when you want to set a default value for a lookup field specified by the user for a search query-by-example form.

  When the criteria of view defines a search query for the user interface form, you can leave the field blank. In this case, the user will provide the value. Alternatively, you can provide a value that will act as a default value to the field search that the user will be able to substitute. This entry can include wildcards * or %.

  When the attribute is of type Date, specify the value of the date in the format YYYY-MM-DD; for example, to December 16, 2010, enter 2010-12-16.

  Here, it tells you that a value is expected. Your sub query is not interpreted, but is simply converted to the appropriate data type. In my example, I get an invalid number as expected.

  So I guess my suggestion to use a custom sql statement stands.

  Hello

  Welcome to the forums!

  What you showed us, I guess that you have created the database manually using the CREATE DATABASE command?

  If so, did you run CATPROC.sql and CATALOG.sql correctly? It seems that your problem is related to these scripts, because they are responsible for creating the tables and the data dictionary views.

  Have you run them with SYS schema?

• Change default file ora initsid locatiton

  Hello
  I installed Oracle 10 G (Express Edition) on my Windows XP. The installation program itself refused to create and start the Oracle database and services, so I created my database manually.

How can I change this location so that each database has its own location of its initialization file. I looked at the register but couldn't find that anything related to init.ora file.

  As far as I KNOW, you can change the service oracle under windows.

  Where the provision is applied first to determine if the line fits criteria. Only if this is the case, select list expressions are calculated. This is why select expression list aliases are not allowed in the where clause. Now, command by after selection list is calculated, so you can use aliases expression list in the order of.

• DataGuard Configuration problem / ORA-16047

  First of all, I noticed a problem with a gap in the sequence numbers.

  Here are the configuration on the primary information:

  The error description is:
  

  Cause:       The DB_UNIQUE_NAME specified for the destination does not match the DB_UNIQUE_NAME at the destination.
  Action:     Make sure the DB_UNIQUE_NAME specified in the LOG_ARCHIVE_DEST_n parameter defined for the destination matches the DB_UNIQUE_NAME parameter defined at the destination.

  As you can see above the DB_UNIQUE_NAME in the parameter LOG_ARCHIVE_DEST_2 to match that of the database pending.
  
  Also DG_BROKER_START is false on the back-end databases and relief.
  
  Finally, I deleted all the files DRC * the directory $ORACLE_HOME/dbs on primary servers and intelligence to make sure that the broker is not configured.
  
  Where am I wrong? How can I get the standby caught up and working properly again?
  
  I apologized if I missed something. I'm relatively new to databases in waiting.

  Centinul;

  I noticed a few things

  1. If you run the query below the sleep mode, you will probably always get the results you've posted

  SELECT sequence #, applied to the order of v$ archived_log by sequence #.

  What to do if run it from primary school and I add the "DEST_ID" column to the query.

  2. you may have more luck finding GAPS using these queries:

  Select max(sequence#) from v$ archived_log in case of application = 'YES ';

  Choose the process, status from v$ managed_standby;

  SELECT * FROM V$ ARCHIVE_GAP;

  3. you mix SQL result with data broker, which can bite you. You don't know where you went wrong, but I would create PFILE file versions before trying to broker data at both ends. You can view each setting and avoid problems before adding the data broker. Data broker will take control and you can even find that it adds entries to your settings file.

  The ORA-16047 is probably related database parameter and that should help at least answer the question. For example you might miss log_archive_config on the standby or soething. In comparing the two PFILE should refine this

  I checked my notes from data broker, but did not find an ORA-16047, ORA-01031, ORA-16675, ORA-12514 and ORA-16608, I managed.

  For me I decided it was a good idea to run Data Guard without data broker at first, until I got the impression using SQL.

  Finally if you have not already consider the purchase of Larry 'Oracle Data Guard 11g Handbook' Carpenter IMHO its worth every penny and more.

  Best regards

• Error in the generator of the ApEx 4 on Edit Page of the article: ORA-06502

  Hello
  
  We took 4 ApEx (patch 4.0.1.00.03), and have a problem in a single application, where appears the error ORA-06502 character string buffer too small.) This error at bottom of the page this article Page. In addition, point editing the page "settings" section is left blank, so I can't change any settings. It also gives me wrong when creating new items, so I have to copy existing elements and change them from place. This worked until recently, when the mistake is now also displayed in the application itself, and not only in the constructor. This is a page with a tabular presentation and some elements of search filter. After having fill the filter and click on a search button, the error message and tables is not rendered. This happens from time to time, and the 'solution' is to disconnect and return to the application. I'm not 100% sure, but I guess that's the same problem as the error appearing in the report generator. It is certainly not caused by user data.
  
  So far, I found this:
  
  While developing the application, we regularly put the generator of the ApEx between French and English. I read that it was a cause of ORA-06502, but that this problem has been resolved in version 4.0.1.00.03. Our problem may still be linked to the multilingual constructor?
  
  I ask this because we are running other applications in the same environment, ApEx, and they are all very good. So somehow this error in Report Designer is related to this particular application.
  
  Any ideas?
  
  Thanks in advance!

  Hello

  (1) no longer this error occurs if you export your application and install it on apex.oracle.com which has 4.0.2?
  (2) do you use point type plug-ins in your application. In 4.0.1 there was a mistake in the generator if too many when installed in this application. Reduce the number of plug-ins type point or better to install 4.0.2.00.07

  I also highly recommend that you stop what you are doing now, remove all database objects that were created with identifiers respecting case-sensitive and re-create them according to standard practical Oracle so that they are case-sensitive. By the database SQL language reference:

  Note:

  Oracle does not recommend the use of identifiers in quotes for the names of database objects. These city identifiers are accepted by SQL * Plus, but they may not be valid when using other tools that manage database objects.

  Names of objects sensitive to case and between quotes identifiers will only cause confusion and error.

  Info * @desc to the col de BLOB XML is as follows

  

  * I also read a ' UTL_COMPRESS. LZ_UNCOMPRESS cannot process the file gzip with FCOMMENT' thread here and I tried the potential workaround here who is trying to manipulate the content of the blob to remove the FCOMMENT... but nothing helps. I must say that I am not sure that it's actually my problem.

  Details on the Zip file I can glean from 7 - Zip are as follows...

  

  * Any ideas please? (If Oracle decompress may have a problem handling the XML data itself... with my way of thinking on the FCOMMENT being a bit of a furphy?)

  * Don't know if the zip file hexview can help, but just in case where is >

  

  I would be very grateful for any help you might be able to give me this.

  UTL_COMPRESS use of LZ compression, which is a version less compression compared to normal ZIP files (that use LZW, often with additional ' Deflate' or other methods).

  Anton Scheffer (member of the these for one) wrote a package to compress and decompress found related to this article on his blog:

• How to remove hierarchical data?

  Hello

  I have a table with hierarchical data. I want to remove the data based on a condition, but maybe that this condition is present only in the upper hierarchy.

  In my example, I have identified by id lines and a changed_by containing the id of the row that has replaced (invalidated) this line. Of these, I want to delete data where descr in end-nodes is 'A '.

  Oracle Database 11 g Enterprise Edition Release 11.2.0.2.0 - 64 bit Production

  DROP TABLE test_del; CREATE TABLE test_del) CONSTRAINT pk_del PRIMARY KEY (id) id NUMBER changed_by NUMBER CONSTRAINT fk_del REFERENCES test_del (id) , descr VARCHAR2 (10) ) / INSERT INTO test_del (id, changed_by, descr) VALUES (3, NULL, 'A'); INSERT INTO test_del (id, changed_by, descr) VALUES (2,3, 'A'); INSERT INTO test_del (ID, changed_by, descr) VALUES (1, 2, NULL); INSERT INTO test_del (id, changed_by, descr) VALUES (6, NULL, 'A'); INSERT INTO test_del (id, changed_by, descr) VALUES (5.6, 'A'); INSERT INTO test_del (id, changed_by, descr) VALUES (10, 'B', NULL); INSERT INTO test_del (id, changed_by, descr) VALUES (9, 10, 'B'); INSERT INTO test_del (id, changed_by, descr) VALUES (8,9, 'B'); COMMIT; SELECT *. OF test_del CONNECT BY PRIOR ID = changed_by START WITH descr = 'A' changed_by AND IS NULL; ID CHANGED_BY DESCR ---------- ---------- ---------- 3            A 2 3 1          2 6            A 3 p DELETE FROM test_del WHERE the descr = "A"; ORA-02292: integrity constraint (FE. FK_DEL) violated - book of the foundling

  Of course, I get ORA-02292 in this case, but how can I write a correct statement that deletes the data displayed by the select?

  Concerning

  Marcus

  You must follow the hierarchy:

  DELETE FROM test_del

  WHERE ROWID IN)

  SELECT THE ROWID

  OF test_del

  CONNECT BY PRIOR ID = changed_by

  START WITH descr = "A".

  AND changed_by IS NULL);

• Syntax of XQuery OK in 11R2, but works only not in 10R2

  I am new to XQuery and I am struggling a little with her, I wrote an insert in our environment 11R2 and when he was deployed in customer 10R2 environment throws an error:
  

  select x.stmt
  from source_table vdx1
  ,    xmltable(xmlnamespaces(default 'urn:iso:std:iso:20022:tech:xsd:camt.053.001.02')
                ,'for $i in /Document/BkToCstmrStmt/Stmt where $i/Bal/Amt/@Ccy = $ccy return $i'
                passing vdx1.content
                , cast(l_ccy_code as varchar2(3)) as "ccy"
                columns Stmt xmltype path '/*'
               ) x
  where vdx1.id = l_vdx_id
  
  ORA-00932: inconsistent datatypes: expected - got CHAR

  The problem lies in the line with "cast", I have basically that data when the value of /Bal/Amt/@Ccy is equal to a certain value that is stored in the variable l_ccy_code. This value varies, so I can just hardcode it.
  
  Is there a way to write this select statement that would be correct for 10R2 environments both 11R2? Is there a better way to write the XQuery for my case, that's what I came up with, but because of my lack of experience with XQuery, it would not be the best solution?

  10.2, the PASSAGE clause allows only XMLType datatype.

  If you pass simple scalar values as in your example, you can use this workaround:

  select x.stmt
  from source_table vdx1
  ,    xmltable(xmlnamespaces(default 'urn:iso:std:iso:20022:tech:xsd:camt.053.001.02')
                ,'for $i in /Document/BkToCstmrStmt/Stmt where $i/Bal/Amt/@Ccy = $ccy return $i'
                passing vdx1.content
                , sys_xmlgen(l_ccy_code) as "ccy"
                columns Stmt xmltype path '.'
               ) x
  where vdx1.id = l_vdx_id
