  FROM       resouce_bundles
  GROUP BY  bundle_name, resource_name
  HAVING       COUNT (CASE WHEN locale = 'cs_CZ' THEN 1 END)     > 0
  

  If you would care to view the information that Centinul mentioned, then I could test it.

  Always better to share create table statement with sample data and the business logic for the output you want, this will help us help you. Here is a way.

  select ms,tg,dt from (
  select ms,tg,dt, max(dt) over(partition by ms,tg order by dt desc) max_dt from
  (
  select ms,tg,dt from tb where (ms,tg) in ( (23,1023),(34,1020),(45,4444))

• Help in to convert CASE to DECODE in 11g sql

  Can someone help me rewrite under sql CASE statement to DECODE?
  

  SELECT INVOICE_ID,sum(TOTAL_EXCL_VAT),LEVEL2 as descr,

  Thank you

  Why would you want to replace the much more expressive syntax of CASES with a DECODING?

  If you are really determined

  DECODE( instr( level2, 'Internet' ), 0, 0, sum_quantity )
  

  I would strongly prefer the option CASE, however.

• Retrieve and display a result set using the dynamic sql?

  Hi all
  
  How would display a result set in Oracle using the dynamic SQL? Reason being, the table where I'd retrieve and display the result set is a GLOBAL TEMP TABLE created in a stored procedure. If I try to use the loop as usual, the compiler complains that the table does not exist. This makes sense because the compiler does not recognize the table because it is created dynamically. Here is an example:
  
  create or replace PROCEDURE maketemptab IS
  sql_stmt VARCHAR2 (500);
  OutputString VARCHAR2 (50);
  
  BEGIN
  -create temporary table
  sql_stmt: = ' CREATE of TABLE TEMPORARY GLOBAL globtemptab (id NUMBER, col1 VARCHAR2 (50))';
  EXECUTE IMMEDIATE sql_stmt;
  dbms_output.put_line ('... created table ');
  
  -Insert a row into the temporary table
  sql_stmt: = "INSERT INTO globtemptab values (1, 'some data of a test')';"
  EXECUTE IMMEDIATE sql_stmt;
  dbms_output.put_line ('... inserted row ');
  
  -Insert a row into the temporary table
  sql_stmt: = ' INSERT INTO globtemptab values (2, "some more test data");
  EXECUTE IMMEDIATE sql_stmt;
  dbms_output.put_line ('... inserted row ');
  
  -Select the row on temporary table
  sql_stmt: = 'SELECT col1 FROM globtemptab WHERE id = 1';
  EXECUTE IMMEDIATE sql_stmt INTO outputstring;
  dbms_output.put_line ('... selected line: ' | outputstring);
  
  -drop temporary table
  sql_stmt: = 'DROP TABLE globtemptab;
  EXECUTE IMMEDIATE sql_stmt;
  dbms_output.put_line ('... moved table ');
  
  -display the result set
  for tabdata loop (select col1 from globtemptab)
  dbms_output.put_line ('... test of recovered data are' | tabdata.col1)
  end loop;
  end;
  
  
  In short, how to rewrite the SQL below the comment "to display the result set" using the dynamic sql?

• Database error-2147217865 Toolikit LV

  Hello.

  Curetly I'm familiar with LV Database Toolkit version 2014.

  In our company we use database on a remote server, so our COMPUTER technician installed on my computer Oracle and sets DSN. Now, in LV, I am able to create the connection and list all the tables in the database, but when I try to display the information in column I get this error:

  "Error-2147217865 occurred at NI_Database_API.lvlib:Conn Execute.vi-> NI_Database_API.lvlibColumns.vi B tools list-> Untitled 1".

  In the possible reasons, it is said that the table does not exist in the database, but this is nonsense. is there something I'm missing? Something in the DSN parameter or...?

  Below is the screenshot of my code and this error message.

  Thank you

  

  Error: ORA-00942: table or view does not exist

  You tried to execute a SQL statement which makes reference to a table or view that either did not exist, you do not have access, or who belong to another schema, and you didn't refer to the table by the schema name.

  There are the options to resolve the Oracle error:

  Option #1

  If this error occurs because the table or view does not exist, you must create the table or view. You can check whether the table exists in Oracle by running the following SQL statement:

  SELECT *.
  Of object
  WHERE object_type IN ('TABLE', 'SEE')
  AND object_name = 'OBJECT_NAME ';

  For example, if you are looking a Suppliers table, you would run:

  SELECT *.
  Of object
  WHERE object_type IN ('TABLE', 'SEE')
  AND object_name = "SUPPLIERS";

  Option #2

  If this error occurs because you do not have access to the table or view, you will need to have the owner of the table/view, or a DBA grant privileges to this object.

  Option #3

  If this error occurs because the table/view belongs to another schema, and you did not refer to the table by the schema name, you will need to rewrite your SQL to insert the schema name.

  For example, you may have executed the following SQL statement:

  SELECT *.
  Providers;
  The suppliers table belong you, but on the contrary, it is owned by an app called schema, you could set your SQL as follows:

  SELECT *.
  OF app.suppliers;
  If you don't know what schema from table/view belongs to the providers, you can run SQL following namely:

  SELECT master
  Of object
  WHERE object_type IN ('TABLE', 'SEE')
  AND object_name = "SUPPLIERS";
  This will return the name of the schema owner of the suppliers table.

• Check the consequential digital beaches / coasts/next

  Hello.

  I have the classic table with the lines:

  Range2 - 4 - 6.99

  Range3 - 7-10

  Are there any known SQL, built-in Oracle, do anything... to check that they are correlative, adjacent or following one after the other?

  In the example above, the validation is true, and if the first value in Range2 was 4.5, validation must be false.

  Thank you. Concerning

  It looks like you want is to use the analytical function LEAD()

  The analytical LAG and LEAD functions you data before lines / following lines in a specific line.

  Be sure to read up on all of the analysis of functions in Oracle provide free manual so that you know what is available.

  It is as an exercise for the student to understand the rest.

• Extract XML Value returns nothing

  Hi, I have a table where I put an XMLTYPE column called XML_RESPONSE and a CLOB called XML_RESPONSE_CLOB with the same XML content each.

  One of the values of records in the two columns look like this:

  <? xml version = "1.0" encoding = "UTF - 8"? >< s : Envelope xmlns:S = » http://schemas.xmlsoap.org/soap/envelope/ « >< Body >< ns2:StampCFDBytesResponse xmlns:ns2 = » http://impl.Controllers.massive.Fe.STO.com/ "xmlns:ns3 = » http://exception.Fe.STO.com/ "><stampedDocument>PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiPz4KPGNmZGk6Q29tcHJvYmFudGUgdmVyc2lvbj0iMy4yIiBmb2xpbz0Cinb2IubXgvVGltYnJlRmlzY2FsRGlnaXRhbCBodHRwOi8vd3d3LnNhdC5nb2IubXgvVGltYnJlRmlzY2FsRGlnaXRhbC9UaW1icmVGaXNjYWxEaWdpdGFsLnhzZCIgeG1sbnM6dGZkPSJodHRwOi8vd3d3LnNhdC5nb2IubXgvVGltYnJlRmlzY2FsRGlnaXRhbCIvPgogICAgPC9jZmRpOkNvbXBsZW1lbnRvPgo8L2NmZGk6Q29tcHJvYmFudGU+</stampedDocument></ns2:StampCFDBytesResponse></S:Body></S:Envelope>

  I am trying to extract the base64 code, that is inside the < stampedDocument > element.

  If I use this code, the procedure runs, but returns nothing:

  Select apex_web_service.parse_xml (XML_RESPONSE, "/ / envelope/body/stampedDocument")

  in v_stamped from f_cfdi_timbrados where id_cfdi_timbrado = 1002;

  If I use the following the procedure returns an error:

  Select apex_web_service.parse_xml (XML_RESPONSE, '//Envelope/Body/stampedDocument/stampedDocument ()')

  Select apex_web_service.parse_xml (XML_RESPONSE, '//S:Envelope/S:Body/stampedDocument/stampedDocument ()')

  Select apex_web_service.parse_xml (XML_RESPONSE, ' / / s: Envelope / Body / stampedDocument')

  in v_stamped from f_cfdi_timbrados where id_cfdi_timbrado = 1002;

  06503 00000 - "PL/SQL: function returned no value."

  * Cause: A call to the PL/SQL function completed, but no RETURN statement has been

  executed.

  * Action: Function to rewrite PL/SQL, ensuring that it always returns

  a value of the appropriate type.

  I also tried with the ExtractValue function and retunrs null or an error.

  SELECT id_cfdi_timbrado,

  EXTRACTVALUE (e.xml_response, ' / envelope/body/stampedDocument ')

  'CFDI_BASE_64 '.

  OF e f_cfdi_timbrados

  WHERE id_cfdi_timbrado = 1002;

  Please notify. It's my first experience of XML parsing and it seems that I am lost.

  Francisco

  The error message provides the clue that you need.  If you were to search on this error message, you will see he's trying to tell you that you are missing a RETURN statement at the end of your function.  Something like

  RETURN v_stamped;

  That would resolve the issue causing the error ORA.

  Regarding the second question, that you will encounter, your clips are not correctly name space which is part of the XML.  For extractValue, there is a third parm

  EXTRACTVALUE

  If your query would look like

  EXTRACTVALUE (e.xml_response, ' / s: Envelope/Body / ns2:stampedDocument ',' xmlns:S = "http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns2 = "http://impl.controllers.massive.fe.sto.com/"')

  I leave you to you of apex_web_service.parse_xml of research

  That said, depending on your version of Oracle, extractValue might be obsolete and you will have to go in a different direction.

• ORA-28132: the MERGE syntax IN does not support security policy

  Hello

  With the help of Oracle 11 g R2.

  I have the following problem:

  If the user attempts to perform a MERGE INTO statement on a table (T1), it receives the error ORA-28132: The MERGE IN syntax does not support security policy.

  Is there a way I can solve this problem by giving the user more rights on this specific table, T1? Or I need to rewrite the SQL code using UPDATE and INSERT instead MERGER?

  I can't grant POLICE ACCESS TAX-FREE, it would be too powerful privilege...

  Please advise,

  M.R.

  You may need to recreate the political VPD:

  Note:

  In previous versions of Oracle database, when you created a strategy Oracle virtual private database on an application that included the MERGE INTO statement, the MERGE INTO declaration could be avoided with a ORA-28132: Merge into syntax does not support security policies error, due to the presence of the virtual private database policy. From Oracle Database 11 g Release 2 (11.2.0.2), you can create policies on applications that include MERGE INTO operations. To do this, in the DBMS_RLS . ADD_POLICY statement_types parameter, include the INSERT , UPDATE , and DELETE statements, or simply omit statement_types setting altogether. Refer to the Oracle Database Security Guide for more information on the application of the strategies on specific types of SQL statement.

  Not if you want the rest of the SQL statement to succeed.

  You could, of course, rewrite the SQL statement to update the individual lines in a PL/SQL loop and catch exceptions in this loop. It will be slower. And involve more code. So, it is not recommended.

  And you should never write a handler exceptions as simply calls dbms_output. There is no guarantee that anyone will ever see dbms_output so it should never be invoked.

• Creation of a "null schema?

  We have a database of vendor 11g where records are distributed between two patterns - ACTIVE patterns and an ARCHIVE. Each object has a corresponding object both of ASSETS and patterns of ARCHIVE.
  
  The seller also has a third scheme where each object is simply a UNION ALL operation of schema objects associated with ASSETS and ARCHIVES. In the sake of the example, I'll call this schema COMBO.
  
  Over the years, we have created queries and reports that reference ARCHIVES and the COMBO patterns and which worked very well.
  
  The seller has set up a secondary database for us that we can use when the primary database is currently offline for the application of patches/updates / etc. The problem is this secondary database has only the scheme ASSETS and records. The seller will write no records of ARCHIVE to it.
  
  In short:
  Primary DB: patterns of ASSETS, ARCHIVE and COMBO
  Secondary DB: only the ACTIVE schema.
  
  This is probably wishful thinking, but is it possible to implement the schemes of ARCHIVE and missing COMBO on the DB side such that we will not have to rewrite our SQL to take account of the absence of a scheme of ARCHIVE when we move reports database backup?
  
  Of course, no record will be returned from the diagram ARCHIVE virtual, but I'd love for intact SQL to run without error.
  
  Thank you!

  You can certainly generate an export of diagrams ARCHIVE and active COMBO, excluding data from the database and import the metadata into the secondary database. Who will create the schema, create the tables, create views, etc., but will not import any data.

  Of course, if the seller changes one of these tables (adding or dropping a column), you will need to apply the same changes to your secondary database.

• Filter LIKE ANY

  Hi, I want to rewrite the sql filter condition:
  where col1 like '% a' or like '% b' col1 col1 like '%c %' or col1 like '
  
  in a simpler format in the same way Teradata allows:
  where col1 like everyone (would be "% a % b ',' ', '%c %',')
  
  What is the equivalent syntax in Oracle? REGEXP_LIKE can be used?
  An example of work please?
  
  Same, simpler format for:
  where col1 like '% a' not and not like 'b %' col1 and col1 and col1 like '%c %' not like '
  
  
  Thank you

  NOT regexp_like(col1,'(a$)|(^b)|(c)|(^d$)')
  

  Also, if I want to match the strings as *'A.B.C.%. OF *.
  where *'. ' * is true simply in the source string, how do I do the regular expression?

  Escape you with backslash:

  regexp_like(col1,'^A\.B\.C\..*\.D$')
  

  Now, back to your original case. Keep in mind, to:

  where col1 like '% a' or like '% b' col1 col1 like '%c %' or col1 like '

  like '% b' Col1 and col1 as would be "will use the index (assuming that col1 is indexed) as:"

  REGEXP_LIKE (col1,'(a$) |) () ^ b) | (c) | (^d$)')

  will not.
