• No support for oracle sql functions

  Hi all
  
  Please can someone explain why the B-tree indexes are not capable of supporting SQL queries using the built-in functions of Oracle.
  
  We have indexes of tree b on account_no column.
  
  Select * from test_table where account_no = 11005208
  
  the above query use the index on account_no
  
  Select * from test_table where superior (account_no) = 11005208
  
  But this query does not use the index on the account_no, going for the full table scan.
  
  My question here is account_no is the numeric data type.
  Then, there is no difference between the data in the columns account_no and upper (account_no) column data, so why he does not use index when using sql functions in an sql query?

  Hello

  If you apply the upper function, Oracle implicitly converts its argument to a string, so your query is actually upper (to_char (account_no)).
  There is none HAVE fully functional in the optimizer and you do not expect to know everything and do all the conclusions that a human being can do. Why should Oracle re - write this type of query analysis the data type of the columns and features when it seems more natural programmer write a correct query (without capital letters in this example) or, if necessary, create an index based on a function?

• 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.

  Who today replaces "ora: see?

  On 11.2, ora expansion feature: view() is deprecated in favor of the fn:collection("oradb:/") method:

  http://docs.Oracle.com/CD/E11882_01/AppDev.112/e23094/xdb_xquery.htm#BABECFFD

  My DBA database have installed Oracle XML DB to use the XMLType and XMLTable, I thought that these features among other things speed up the creation of XML.

  What are the benefits of using XQuery and XMLTable and XMLQUERY functions?

  Which version of the database you use?

  Please read: http://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb_xquery.htm#CBAGCBGJ

  Is there another method to expedite the creation of XML?

  Publication of SQL/XML functions are probably the best way to create custom relational data XML documents.

  The basic functionality of XQuery is not to the RDBMS query tables or views, although Oracle provides extensions to do.
  Most of the time, I use XQuery (via XMLTable and XMLQuery) to do exactly the opposite, i.e. to extract XML data in a relational form, or the transformation of XML fragments.

  If your actual requests are slow - even if you need to define what that means and that you are pregnant - then maybe the SQL/XML functions are not the real problem.

  In a "Where clause" as I turn, I have several "outer join". Here is an example.

  where
  PPM. NSU_PPM = w.NSU_PPM and FRNS. NSU_FRN (+) IS FCO. NSU_FRN and FCO. NSU_FCO (+) IS PPM. NSU_FCO
  and T2O. NSQ_T2O (+) IS PPM. NSQ_T2O
  and T51. NSQ_T51 (+) IS PPM. NSQ_T51
  and TWU. NSU_STT (+) IS PPM. NSU_STT
  and T01. NSQ_T01 (+) IS PPM. NSQ_T01
  and vpm.cod_rmp_vpm (+) = "PRA".
  and vpm.num_vsn_vpm (+) = PPM.vsn_sup
  and w.nsu_ppm = A.nsu_ppm (+)
  and W.NSU_SOO = A_HEADER. NSU_SOO and A_HEADER. NOR_SOM = 0

  Yes, it's exactly what I was talking about.
  Transposing the logic for XQuery 1.0 is not the approach more simple (to say the least), because there is no direct support OUTER JOIN.
  XQuery 3.0 provides the functionality, but it is not yet here in the database.

  My suggestion would be to stick to the publication of SQL/XML functions.
  If you have a specific question about the performance, we (as the members of the forum) will be happy to help you.
  Provides the steps necessary to reproduce the problem, including some examples of data.

  Kind regards

• Pass a list of values to a pl/sql function

  I would like to pass a list of values to a pl/sql function where the list will be used in an IN clause. Ideally, I would like to do the following:
  
  CREATE or REPLACE FUNCTION (dept_list in varchar2)
  Start
  Select... where dept in (dept_list);
  
  use: process_list ('7730,7735,7740,7745');
  
  I can't find an example to do based on pl/sql, but it seems feasible.
  Is there a way to do this?

  use: process_list ('7730,7735,7740,7745');

  The first thing is that you need an appropriate data type for storing a list of numbers. A unique value that look you like a list of numbers, is not actually a list of numbers but a single character value.

  This example uses the built in odcinumberlist data type in a procedure, you can do the same in function

  Re: Pass an array to an Oracle stored procedure

  If you have an older version of the database, you may need to create your own type with the same definition of odcinumberlist.

• 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.

• Allowing access only through a PL/SQL function

  What is the technique of letting a user to do something by a PL/SQL function that would normally not have the privilege to do so, without granting the possibility to do outside the PL/SQL function?
  
  I have a need to allow a user to change the global_name of the database, in the resolution of ORA-02082 errors. In short, the product using Oracle (we can not change code) loopback database links, and the only way to drop them (according to the Oracle support) is to temporarily change the global_name, drop the link and change the global_name return.
  
  This happens on a semi-regular basis, so rather than having to involve a DBA, I favor.
  
  My thought was to create a PL/SQL procedure that performs the Rename/move/rename. I don't want the user to be able to change the global_name of DB to what he wants, but I want him to have the possibility to change through the PL/SQL procedure at will.
  
  My question is, how to do this without allowing the user to update on sys.global_name?
  
  Let's see:
  
  (1) create a role (say LOOPBACK_DBLINK_DROPPER)
  (2) create a procedure (say LOOPBACK_DBLINK_DROP) makes the Rename/move/rename
  (3) grant and then execute the procedure to the role
  (4) ??? .. .the I need to give an update on sys.global_name for the role. But if I then assign the role to a user, is not that means he can also update sys.global_name on its own without using the procedure, because it would have the sys.global_name privilege update?

  Create the schema belonged procedure that has the necessary privileges.
  GRANT EXECUTE on LOOPBACK_DBLINK_DROP to NON_PRIV_USER

  That's all!

• APEX shortcuts using the source of the body of the PL/SQL function

  Hi all
  
  Recently, I came across the feature of "Shortcuts" in the "Shared components" section of the APEX and thought great, somewhere to set the common/standard items once, then use these several times in different pages of my application.
  
  This seemed to work correctly when you use the 'Source' of "HTML Text" or "HTML text with special characters escaped", but then I wanted to explore the use of the "Body of the PL/SQL function" option to create a more dynamic shortcut/variable on the base.
  
  This is where I came across a particular problem in the APEX (Version 3.2.1.00.10 on GR 11, 2 on Oracle Enterprise Linux). When I set my shortcut, and then perform a reference to my shortcut (using "MY_SHORTCUT") in an area of a page, the value of shortcut is back, but is added with the reference variable (ie. the 'MY_SHORTCUT' chain).
  
  For simplicity, my example looks like this (of course, my real world example is a bit more complicated, but this example produces the same error):
  (a) I define my shortcut called "MY_SHORTCUT" and using the body of the PL/SQL function under "Source Type", define my procedure as "htp.p(:USER)."
  (b) I then create a new page (basic HTML page), and a new region of the 'type'-> 'HTML Text (with shortcuts).
  (c) in the "Source region", I define my shortcut like - "MY_SHORTCUT".
  (d) I apply changes and then run the page.
  
  I'll be back will be name of the current user with "MY_SHORTCUT" appended/added immediately after the user name - for example. the string:-' BRAD «MY_SHORTCUT»»
  
  Question is - how to stop the shortcut/reference text "MY_SHORTCUT" to be added to the variable you want to see the and thereafter on your page? I am just wanting the variable, NOT the reference for the shortcut.  I do something wrong using the HTP package, and if yes, what should I use?
  
  If "MY_SHORTCUT" is defined as "HTML text with special characters escaped" (where I can refer to elements of application using the syntax '& USER.') so that everything works correctly. My reason for using the PL/SQL is to generate a more dynamic output variable, based on elements of application throughout the entire application - and of course the use of shortcuts to minimize coding and duplication.
  
  
  Thanks in advance,
  Brad

  Hello

  The body of the PL/SQL function must RETURN a value.

  Try:

  RETURN :APP_USER;

• Replace the trivial calculation with PL/SQL function?

  I have several queries that are full day based on a date field differences Oracle - for example, something along the line of computing:
  
  Select
  Customer
  , trunc (current_date) - trunc (payment_date)
  Of
  (select 'Fred', to_date ('2009-06-01 07:05 ',' yyyy-mm-dd hh24:mi:ss') as payment_date of all the double union)
  Select 'Barney', to_date ('01-07-2009 15:15:15 ',' yyyy-mm-dd hh24:mi:ss') of double
  )
  -- ------------------------------------
  --
  -Customer Account_Age
  -- --------- -----------
  -Fred 49
  -Barney 19
  
  I'm a developer who is now Advisor we use a user defined PL/SQL function rather than the difference of these functions TRUNC. Who goes against the grain for me. In MS SQL Server Transact SQL forums, I would recommend almost never replace something trivial with a user defined function because the UDF is called for each row returned by the query and adds overhead to the application.
  
  The same kind of logic applies to the UDF Oracle? Is it a good idea to replace trivial calculations like this with the UDF?
  
  
  Kent Waldrop

  If you can do it in sql, avoid any need for a function.

  I was creating a calculation for a page element by using the type 'BODY of the PL/SQL FUNCTION '. Step by step in the wizard when I entered my code block, I received the error PLS-00372. Here is the code:
  
  DECLARE
  l_return person_v.full_name%TYPE: = 'UNKNOWN ';
  BEGIN
  
  SELECT full_name
  IN l_return
  OF person_v
  WHERE party_id =: P230_CONTACTED_PARTY_ID;
  
  RETURN l_return;
  EXCEPTION
  WHEN NO_DATA_FOUND THEN
  RETURN l_return;
  END;
  
  If I change my name of the variable to another thing that l_return the error disappears. Later, I can't change the name of the variable in l_return and I do not get the error if it seems to be the validation happening on just this page of the wizard.

  Greg - it's because of a quirk in the validation, like imagine you. Workaround is to put a space between return characters and the terminal semi-colon, for example:

  RETURN l_return;

• Filling point with the body of the pl/sql function

  Hello
  
  I want to fill an item "Show as text (saves the State)" in contrast to the other 2 points.
  
  The source of my question is:
  -Only when the current...
  -Body of PL/SQL function
  -Term source:
  DECLARE
  v_diff NUMBER;
  BEGIN
  v_diff: =: P1_AUFWAND_TOTAL -: P1_AUFWAND_BERECHNET;
  Return v_diff;
  END;
  
  Now I get this error:
  
  ORA-06502: PL/SQL: taking oder Wertefehler: Fehler beim zu if indication Zahl von
  Error ERR-1904 unable to calculate the default item: type = body of the function...
  
  I tried to find the problem with the conversion to_number:
  v_diff: = to_number(':P1_AUFWAND_BERECHNET'); or
  v_diff: = to_number (': P1_AUFWAND_BERECHNET', '999G999D00');
  
  What's not here? It's as if I'm making a simple mistake...
  
  Thanks for any help,
  Roger

  If the following code does not work for you, then one of the two elements are not the numbers:

  DECLARE
     v_diff   NUMBER;
  BEGIN
     v_diff := TO_NUMBER (:p1_aufwand_total)
               - TO_NUMBER (:p1_aufwand_berechnet);
     RETURN v_diff;
  EXCEPTION
     WHEN OTHERS
     THEN
        RETURN SQLERRM;
  END;

• Chain replication using a sql function...

  Is there a sql function that reproduces a string given so many times that appears in a parameter...?
  For example: String-> test
  
  Select < sql_function > ('test', 3) double

• 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.
