  Hello Salim
  This feature does not exist inside the discoverer.

  My suggestion would be to create a SQL function, then import it in Finder using the System Administration tool. Now, you will be able to pass the deptno to the function and the function returns a single string containing the concatenated names.

  This isn't a function difficult to write and if you would like some help please let us know.

  Best wishes

  Convert .xls in .csv file using pl/sql

  I know that it s a long time but just wanted to know if there is a way to convert excel .csv.

  I have a directory say 'F:\purple_top\ '. I'll get the .xls file in this directory. I need to change to .csv and tables load external oracle. Any ideas or advance coding on it since 2009 so far?

  A few other options might be:

  • Java code, which can be used from within Oracle, which makes use of utility libraries (e.g. Aspose.Cells) open source (for example Apache POI) or "save under" CSV, or read the source cells and their output to a CSV file.
  • COM Automation, using available open source (for example, JACOB or j-interop) or commercial libraries, which can automate Excel to open a XLS file and "Save as" a CSV file. In addition, Oracle has a feature of COM Automation (available since version 8 but abandoned after Oracle 11g). I have successfully used this read (non-macro-enabled) Excel files in PL/SQL.
  • Other approaches using Perl or PHP can be found by googling 'convert xls to csv.

• convert to oracle pl/sql

  Hi all
  
  can - anybody know how convert transact sql from sql server to oracle pl/sql.is any them tool or whatever is available.
  
  Kind regards
  Ankur

  Frankly - it's all just stupid to convert T - SQL in PL/SQL.

  There are significant differences between these two. PL is a real procedural and declarative language. It has features of OBJECT-oriented programming. It is absolutely nothing like T - SQL.

  Oracle is also different from SQL-Server. There are conceptual major and fundamental differences. After all, why do you buy Oracle customers? Because it's just like SQL-Server? Or because it is not and is very different from SQL-Server?

  Oracle is a very poor imitation of SQL-Server. It has no sense to treat it as SQL-Server.

  And in this vein, it is meaningless to implement the fundamental concepts of the T - SQL and SQL-Server by converting in PL/SQL. The result will probably happen again worse than what he has done in SQL Server. He will not be able to scale. It will be difficult to maintain. It will not use the features of Oracle that puts a technically superior product of RDBMS of SQL Server to Oracle.

  It only converts SQL Oracle server. A ports. And this is refactoring and redesign to better utilize the features of Oracle. Another thing, how can you only achieve the perceived benefits and the benefits of the passage of the SQL for Oracle Server?

• Anonymous performer of Oracle PL/SQL in the Production environment leave a residue?

  Hello

  In my project, we have a large PL/SQL in Prod-Replica Envt to generate scripts. However, to reproduce Prod for this Prod-Replica lasts long and is causing a delay to respond to change requests.

  We have READ ONLY access to Prod DB, but we cannot deploy the PL/SQL Package it. We plan to convert the PLSQL in an anonymous block PLSQL and running it in PROD DB to get real data. Alternatively, we can run it directly or via Java and then read the DBMS output later. as mentioned here-> the use of cursors and results in Oracle PL/SQL, Java/JDBC - Stack Overflow

  , However, is not an expert in PL/SQL, I wanted to know, if it leaves residues in PROD outside the additional load a temporary server for read queries. We only select queries in this PL/SQL and so I donot believe we leave triggers or change the DB somehow.

  Can you please let me know the possible consequences of it.

  -Thanks & Regads

  There will be an impact on the server, the conversion of code unit of PL/SQL (procedures and functions) must be encapsulated in a single code PL/SQL anonymous block.

  This anonymous PL/SQL code block needs to be parsed and compiled - burn a lot of CPU (that oppose the use of unit code already compiled PL/SQL).

  This anonymous PL/SQL block is likely to be very large because it contains too many units of PL/SQL source code. This needs memory to the server as the whole code block will be stored in the shared pool (for analysis).

  Another impact on performance would be wise to network. It requires more bandwidth to transfer this big block of code (created by the customer) to the Oracle server. This increases latency. And is not an evolutionary approach.

  So no, there is no "residue" of the code inside the actual physical database code is never stored in the database. However, this approach and the code will affect negatively network and server resources.

  You should consider the problem and determine if this solution you have in mind, justifies this impact.

• XPath functions in oracle

  Hello
  
  Is there a function like fn:local - name (.) in oracle XPATH functions. If so help me wit ha simple example.
  
  I am new to Oracle & SQL server migration procedure to oracle where script XML procedure taken as input.
  
  I need to convert under Oracle's SQL Server select statement.
  
  SELECT converseUID,
  "Distributed."
  Cast (ServiceCalls.Query ('fn:local - name (.)') as varchar (100)).
  1,
  WORK IN PROGRESS. ServiceCalls.value ('(TotalTime) [1] ',' int'),

  @DateTimeStamp
  OF @WIP.nodes('//WIP/gatewayServiceCalls/*') as WIP (ServiceCalls)
  WHERE WIP. ServiceCalls.value ('(startTime) [1] ',' int') <>0
  
  Thanks in advance.

  The path expression is bad and which is based on the XML code you posted earlier, VARCHAR2 (4000) is not large enough to hold the extracted value.

  You can use the CLOB data type:

  SELECT x.response
  FROM XMLTable(
         '//WIP/gatewayServiceCalls/mqdrop'
         passing v_wip
         columns
           response   clob  path 'Response'
       ) x
  ;
  

  or, if you expect a single value then preference:

  SELECT XMLCast(
           XMLQuery('//WIP/gatewayServiceCalls/mqdrop/Response'
             passing v_wip
             returning content
           )
           as clob
         )
  FROM dual;
  

• Convert the MySQL timestamp into a Unix timestamp field

  I have a process where I want to compare the current date with an expiration date is so many months after the date of registration. The registration date is stored as a MySQL timestamp. I want to convert this to a timestame Unix I can do the comparison with the Time() function. I tried the MySQL UNIX_TIMESTAMP both getTimestamp() PHP functions and can not get to work. I tried UNIX_TIMESTAMP in both the original SELECT statement and a stand one. I also have an error of division by zero with date_default_timezone_set function. I am attaching the screenshots of the code and the result of the echo inside. Thank you!

  

  

  You are far too complicated.

  SELECT TO_DAYS (reg_date) - AS TO_DAYS (CURDATE ()) daysleft

  OF ssregis

  WHERE...

  This will give you the number of days remaining before the expiry of the registration. If it is less than 0, redirect to the renewal page.

  Moreover, you yourself laying wide open to attack by SQL injection by failing to escape at the entrance of the query string. At the very least, you should do this:

  $entered_ss_id = mysql_real_escape_string($_GET['record_id']);

  $entered_email = mysql_real_escape_string($_GET['email_address']);

  However, since it seems that you are hand-coding the script, you must use MySQL improved rather than discouraged PHP MySQL functions. See http://docs.php.net/manual/en/mysqlinfo.api.choosing.php.

• write a view with function in oracle

  Hi all

  I have a table named border, contains the borders of certain countries.

  and then I did notice, for symmetric data, which means that if I have a folder {ch, OF} I {, ch}.

  so I want another opinion, preferably with the help of functions, to show me that these results, the first view must be used, not the main table, to create this view.

  en, 1

  pl, 1

  UK, 2

  read, 2

  read, 3

  This means between these countries, we have these quantity of bordes, but we just want to see these up to 3 borders, not more.

  Thanks for your reply.

  IM using oracle 10 g and linux ubuntu 12.

  First of all, I have a table illustrating the countries

  {code}

  -File created - Sunday-November-24-2013

  --------------------------------------------------------

  --------------------------------------------------------

  -The DOF for Table BORDERS

  --------------------------------------------------------

  CREATE TABLE 'borders' ('Country1' CHAR (2), 'countries2"TANK (2), the NUMBER of 'LENGTH')

  INSERTION of REM in borders

  TOGETHER TO DEFINE

  Insert into borders (countries1, countries2, LENGTH) values ('from', 'fr', 381);

  Insert into borders (countries1, countries2, LENGTH) values ('from', 'ch', 494);

  Insert into borders (countries1, countries2, LENGTH) values ('from', 'pl', 148);

  Insert in borders (countries1, countries2, LENGTH) values ('ch', 'fr', 608);

  Insert in borders (countries1, countries2, LENGTH) values ('ch', 'it', 318);

  Insert into borders (countries1, countries2, LENGTH) values ("ch", "li", 240);

  Insert into borders (countries1, countries2, LENGTH) values ('he', 'if', 306);

  Insert into borders (countries1, countries2, LENGTH) values ('he', 'DM', 584);

  Insert into borders (countries1, countries2, LENGTH) values ('en', 'read', 549);

  Insert into borders (countries1, countries2, LENGTH) values ('en', 'of', 1000);

  Insert into borders (countries1, countries2, LENGTH) values ('pl', 'ru', 628);

  Insert in borders (countries1, countries2, LENGTH) values ('pl', 'sk', 126);

  Insert into borders (countries1, countries2, LENGTH) values ('UK', 'au', 1800);

  {code}

  and then I have a symmetrical data view:

  {code}

  SELECT B.COUNTRY1, B.COUNTRY2

  BORDERS B

  UNION

  SELECT B.COUNTRY2, B.COUNTRY1

  BORDERS B

  {code}

  Of course you can do it in a function. But why write a function where possible in SQL using the features of Oracle wrote to us ;-)

  'min way' is the key here sentence. You said... for example, we do not want {en, 3, 1000}

  Is it because that {en, a, 2} is already covering en-> of?

  In, this case may be something like this... I am sure that other members may provide the most effective solution.

  But please review these suggested solutions build further and learn SQL/capabilities in Oracle. After all, it's that you should maintain and build on this code. Play with this code and see what makes each step. You will be able to solve the problem that you encounter in yourself. Basically, it is the main objective of these forums.

• Why we need to create the package instead of procedure or function in Oracle

  Hello
  
  Recently, I attended an interview, they asked,
  why we must create the package instead of procedure or function in oracle. Is a specific advantage, if we create together.
  I'm not sure. can u tell me please someone.
  
  Thank you and best regards,
  Sanjeev.

  Hello

  A part of the oracle documentation.

  What is a PL/SQL Package?
  A package is a schema object which includes subroutines, variables, and logically related PL/SQL types. Packages have two parts: a specification (spec) and a body. Sometimes, the body is unnecessary. The specification is the interface to the package. It declares the types, variables, constants, exceptions, cursors, and subprograms that can be referenced from outside the package. The body defines queries for the sliders and the code for the subprogrammes.

  Benefits of the PL/SQL Packages
  Packages have a long history in software engineering, offering important characteristics for a reliable, maintainable, and reusable code, often in team for large systems development efforts.

  Modularity

  Packages allow you to logically encapsulate Associates types, elements, and subroutines in a module named PL/SQL. Each package is easy to understand, and the interfaces between packages are simple, clear and well defined. This facilitates the development of applications.

  Easier application design

  When you design an application, all you need initially is the interface information in the package specification. You can code and compile a spec without his body. Stored subprograms that reference the package can then be compiled as well. You should not set the package body entirely until you are ready to complete the application.

  Information masking

  With packages, you can specify which types, elements, and subprogrammes are (and accessible) public or private (hidden and inaccessible). For example, if a package contains four subprogrammes, three can be public and one private. The package hides the implementation of the subprogramme private so that only the package (not your application) is affected if the application changes. This simplifies maintenance and improvement. Also, by hiding the implementation details of the users, you protect the integrity of the packaging.

  Feature added

  Sliders and packed public variables persist for the lifetime of a session. They can be shared by all the subprogrammes that are running in the environment. They allow you to manage data in any of the transactions without storing in the database.

  Best performance

  When you call a subprogram packaged for the first time, the whole package is loaded into memory. Subsequent calls to related subprograms in package require no disk i/o.

  Packets stop cascading dependencies and avoid an unnecessary recompilation. For example, if you change the body of a packaged function, Oracle does not recompile other routines that call the function; These routines only depend on parameters and return value that are declared in the specification, so they are recompiled only if the specification changes.

• Unlike char in ORACLE and SQL SERVER

  Hello gurus,
  
  I tried to querying data from Oracle to sql server through linked server, but get me an error! set length corresponds to the error! I know there are CHAR data type in sql server and thus as in oracle.
  
  But when I use the CAST FUNCTION with CHAR it works fine
  

  -- error code 
  
    select * from openquery( linkoracle11 
             select  col1, col2, col3 from test_table )
  
  
  -- say col3 char(1)   -- data type

  ---
  
  

  -- working code 
  
    select * from openquery ( linkoracle 11 
             select  col1, col2, cast (col3 as char(1)) as col_3 from test_table )

  I was wondering, what is the difference between oracle and sql server for the CHAR data type?
  
  The gurus of the idea?
  
  Thank you

  What is the error you get?

  What is the characters in database and NLS_LENGTH_SEMANTICS game on your Oracle system?

  SELECT *
    FROM v$nls_parameters
   WHERE name LIKE '%CHARACTERSET';
  
  SQL> SHOW PARAMETER nls_length_semantics;
  

  What is the character set of data in SQL Server?

  If your local database is a variable length character set (like UTF8) and NLS_LENGTH_SEMANTICS is set to (default) BYTES, a char (1) allocate 1 byte of storage which may not be sufficient for a single character. The receiving application may need to allocate a buffer with 3 times more many bytes as there are characters in order to ensure that it will be able to process the result. I don't know why add an implicit CAST that would change, but since we are several levels removed from the code to figure out how large a buffer to allocate, it is not very surprising.

• Any difference between the separate function and aggregation in sql query cost?

  Hello
  I've run many models sql stmts - such as:
  one) using a single table
  (b) using the two tables, using simple joins or outer joins
  
  but I didn't notice a difference in sql stmts in cost and implementation plan...
  In any case, my colleague insists on only using the aggregate function is less expensive compared to
  separate... (something I've not confirmed, that is why I believe that they are exactly the same...)
  
  For the situation described above under 1 sql... We could for example use
  

  select distinct deptno
  
   from emp

  select count(*), deptno
  
   from emp
  
   group by deptno

  select distinct owner, object_type from all_objects

  select count(*), owner, object_type from all_objects
  
  group by owner, object_type

  Have you ever found no difference between the two...?
  
  Note: I use Ora DB 10g v2.
  
  Thank you
  SIM

  Alexandre Gelin says:
  function separate and aggregation are for different uses and can give the same result, but if you use the aggregate function to get the separate records, it will be expensive...

  really? I find them almost identical to 11g. Actually GROUP BY is almost always more fast for me in the old days.

  article about this askTom Re: any difference between the separate function and aggregation in sql query cost?
  This applies mainly to the older oracle versions http://www.oracle.com/technology/products/rdb/pdf/distinct_derivedtables_groupby_sort_tech_article.pdf

• What is this new SQL Beta - 1z1 - 071 - 2 SQL - Oracle Database SQL 12 c

  Hello

  It's confusing.

  This looks like a 2nd review SQL for Oracle 12 c.

  What is this new SQL Beta - 1z1 - 071 - 2 SQL - Oracle Database SQL 12 c

  Can someone explain.

  Roger

  OK - I guess I should have held off a few hours before my previous answer.  I just got an email in the Certification of Oracle program manager. Now, I have inside information.

  1Z0-071 is a SQL new test and the role it plays is between that of the review of databases SQL and SQL Expert.  Specifically, unlike review of databases SQL, passing it will give proof of the OCA for people who spend. I don't know more than that yet.  The review details page is not available and if the subjects are currently a grey area for me.  I'll probably create a blog on the review, if I can get a few details about it.

• Oracle PL/SQL Obfuscation replicate 3DES with java

  I have an existing oracle functions that use the function DES3Encrypt and DES3Decrypt.

  I need to write the equivalent of java version to replace the oracle those compatibiliy with encryption legacy system maintenance.

  What are the functions of oracle:

  FUNCTION encr(input_string IN VARCHAR2, key_string IN VARCHAR2)
  RETURN VARCHAR2 IS
  encrypted_string := NULL;
  len  := lengthb(input_string);
   --String must be a multiple of 8-byte length.
  rest := len MOD 8;
  IF rest > 0 THEN
  decrypted_string := rpad(input_string, len + 8 - rest, ' ');
  ELSE
  decrypted_string := input_string;
   END IF;

  dbms_obfuscation_toolkit.DES3Encrypt(input_string  => decrypted_string,
  key_string  => key_string,
  encrypted_string => encrypted_string);

   /* HEX notation to avoid UNICODE chars */
  SELECT RAWTOHEX(encrypted_string) INTO encrypted_string FROM DUAL;

  RETURN encrypted_string;
END;

//DECRYPTION
FUNCTION decr(input_string IN VARCHAR2, key_string IN VARCHAR2)
  RETURN VARCHAR2 IS
  decrypted_string := NULL;
  encrypted_string := input_string;

   /* HEX to ASCII */
  SELECT utl_raw.cast_to_varchar2(encrypted_string)
  INTO encrypted_string
  FROM DUAL;

  dbms_obfuscation_toolkit.DES3Decrypt(input_string  => encrypted_string,
  key_string  => key_string,
  decrypted_string => decrypted_string);

  RETURN rtrim(decrypted_string);
END;

  Given the Decrypt function, for example, I wrote this java code:

  
  

  import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;


public class DesHelper {
  

     private Cipher _dcipher;
       public DesHelper() {
           try {

               byte[] tdesKey = new byte[24];
               System.arraycopy("2557133392096270".getBytes(StandardCharsets.US_ASCII), 0, tdesKey, 0, 16);
               System.arraycopy("2557133392096270".getBytes(StandardCharsets.US_ASCII), 0, tdesKey, 16, 8);

               final SecretKey key = new SecretKeySpec(tdesKey, "DESede");
 
               _dcipher = Cipher.getInstance("DESede/CBC/NoPadding");
               final IvParameterSpec iv = new IvParameterSpec(new byte[8]);

               _dcipher.init(Cipher.DECRYPT_MODE, key,iv);

          } catch (final Exception e) {
              throw new RuntimeException(e);
          }
      }

  
      public String decrypt(final String str) {
          try {

                final byte[] dec1 = hexToBytes(str);
              final byte[] decryptedBytes = _dcipher.doFinal(dec1);  
              return new String(decryptedBytes, StandardCharacters.US_ASCII);
          } catch (final Exception e) {
              System.out.println("decrypting string failed: " + str + " (" + e.getMessage() + ")");
              return null;
          }
      }

     private static byte[] hexToBytes(final String hex) {
          final byte[] bytes = new byte[hex.length() / 2];
          for (int i = 0; i < bytes.length; i++) {
              bytes[i] = (byte) Integer.parseInt(hex.substring(i * 2, i * 2 + 2), 16);
          }
          return bytes;
     }

  }

  It's the main:

  Public class MainClass {}

  Public Shared Sub main (final String [] args) {}

  String txtToBeDecrypted = "DA67C73756184F20ED92DF1614CB85ED";

  final DesHelper h = new DesHelper();

  String xc = h.decrypt (txtToBeDecrypted);

  System.out.printls (XC);

  }

  }

  


  But the printed result is still a mess of characters like these:

  lZ5 ????rd      

  where only "rd" is correct (being the last part of the decrypted Word).

  the correct decrypted word should be 'MonMotpasse '.

  If the password is transformed into mypasswordmypass (encrypted: 5543417F4834268A2799D9289D864BFB)... I get: lZ5? rdmypass-> it seems that the first 64 bits are always false.

  What is the problem in my code? is it just a matter of encoding?

  Message modificato da 3136775 added new snippet for completeness

  I found that the tip is in the vector of inialization IV...

  I wrote an algorithm to capture the right bytes value and it worked... it seems not oracle uses to manipulate the first 8 bytes.

  Unless you are looking for something I'm not, what actually is the 1Z0-117 page says: "validated against: review has been validated against Oracle Database 11g Release 2 version 11.2.0.1.0 and database Oracle 12 c 12.1.0.1.0"

  What they actually mean by it is that someone went through all the issues and and asked the question "is still a relevant issue for the release of 12 c to Oracle?'." "  If they find issues that are not valid because of an update/change, then the question will be removed from review (or changed) so that someone who has used 12 c but not 11 g will not at a disadvantage.

  This is * No * means that Oracle has added questions to the review of the capabilities that were introduced in version 12 c.

• difference between the incremental update of the IKM oracle and incremental update IKM oracle (PL - SQL)

  Hello

  What is the difference between the incremental update of the IKM oracle and updated incremental IKM oracle (PL - SQL) and incremental update IKM oracle (line by line).

  Thank you

  Papai

  The only difference is that the second using plsql for incremental update. He also to manage clob issues well enough.

  If you need to know more you can read the description of each KM section.

  Incremental update IKM Oracle (PL-SQL)

  -------

  Description:

  -Knowledge integration module

  -Integrates data into an Oracle table from target in incremental update mode using PL/SQL.

  -Non-existent rows are inserted. already existing lines are updated.

  -Data can be controlled. Data invalid are isolated in the error Table and can be recycled.

  -This KM uses PL/SQL to perform the inserts and updates until and blob columns are supported. Please see the restrictions.

  -When you use this module with a source table logged, it is possible to synchronize the deletions.

  Restrictions:

  -When working with the logged data, if the "synchronize destruction of the newspaper" are executed, the lines deleted on the target are engaged

  -The data are updated even if not changed (upgrade from any (e)

  -The number of lines (number of inserts/changes) is not available because the transactions are performed using PL/SQL

  -Comparison of the data is performed using the key to update defined in the interface. It must be set.

  -L'option TRUNCATE does not work if the target table is referenced by another table (foreign key)

  -Options FLOW_CONTROL, and STATIC_CONTROL call the Module knowledge check to isolate invalid data (if no CKM is defined, an error occurs). These two options should be set to NO in the case where an integration Interface meets a TEMPORARY target data store.

  -L' FLOW_TABLE_OPTION option is set by default to NOLOGGING. Set it to a space if the interface is running on an Oracle 7 database

  -Deletions are committed regardless of the VALIDATION option

  Incremental update of the IKM Oracle

  -------------

  DESCRIPTION:

  -Integrates data into an Oracle table from target in incremental update mode.

  -Non-existent rows are inserted. already existing lines are updated.

  -Data can be controlled. Data invalid are isolated in the error Table and can be recycled.

  -When you use this module with a source table logged, it is possible to synchronize the deletions.

  REQUIREMENTS:

  -The update key defined in the interface is required.

  RESTRICTIONS:

  -When working with the logged data, if the "synchronize destruction of the newspaper" are executed, the lines deleted on the target are engaged

  -L'option TRUNCATE does not work if the target table is referenced by another table (foreign key)

  -Options FLOW_CONTROL, and STATIC_CONTROL call the Module knowledge check to isolate invalid data (if no CKM is defined, an error occurs).

  These two options should be set to NO in the case where an integration Interface meets a TEMPORARY target data store.

  -L' FLOW_TABLE_OPTION option is set by default to NOLOGGING. Set it to a space if the interface is running on an Oracle 7 database

  -Deletions are committed regardless of the VALIDATION option

  -L' ANALYZE_TARGET option will allow to assess correct statistics only if the VALIDATION is set to Yes. Otherwise, the IKM gather statistics based on old data.

  -Default UPDATE option is TRUE, which means by default it is assumed that there is at least one column nonkey specified in a target data store.
