• Create Or Replace function error

  Hello
  
  I do the search of texts using Oracle SQL Developer: ODMiner... I imported the "WEBLOG" data into a table... These weblog data consists of the activity of users, date, time, url, etc. The first step I took was to use a function to convert the date and time I have in the data table, in a number representing the 40 minutes since 01/01/1990. I did it by dividing by 2400 (seconds in 40 minutes). The main objective is to have a period of time for the sessions.
  I used the following code,
  
  (SsnDate) CREATE or REPLACE FUNCTION
  DEFAULT VARCHAR2 03/01/18 EFFECTIVE DATE,
  TIME IN VARCHAR2
  ) RETURN NUMBER
  AS
  BEGIN
  RETURN TRUNC ((to_date(DATE||) e '|| TIME, ' Hh: mm: DD-MM-YY ')-to_date('01-JAN-1990','DD-MON-YYYY')) * (86400/2400);
  END ssnDate;
  
  This is what appeared in the newspaper after the execution of the statement,
  
  SsnDate compiled FUNCTION
  WARNING: the execution is completed with warning
  
  After that, I tried to create a VIEW to change the DATE and TIME with the ssnDate that was created earlier and concatenate the CS_URI_STEM (which is the accessible resource) and CS_URI_QUERY (which is the query, if any, the client was trying to perform) in a new field called WEB_LINK.
  
  This is the code used
  
  CREATE OR REPLACE VIEW WEBLOG_VIEWS ("C_IP", "WEB_LINK", "CS_USER_AGENT", "SESSION")
  AS
  SELECT ssnDate (LOG_DATE, LOG_TIME) AS "SESSION."
  C_IP,
  CS_USER_AGENT,
  (CS_URI_STEM |'?) ' || CS_URI_QUERY) AS WEB_LINK
  OF THE WEB BLOG.
  
  Now that I got the following error...
  
  Error from the 1 in the command line:
  CREATE OR REPLACE VIEW WEBLOG_VIEWS ("C_IP", "WEB_LINK", "CS_USER_AGENT", "SESSION")
  AS
  SELECT ssnDate (LOG_DATE, LOG_TIME) AS "SESSION."
  C_IP,
  CS_USER_AGENT,
  (CS_URI_STEM |'?) ' || CS_URI_QUERY) AS WEB_LINK
  WEBLOG
  Error in the command line: 3 column: 38
  Error report:
  SQL error: ORA-00923: KEYWORD not found where expected
  00923 00000 - "FROM keyword not found where expected"
  * Cause:
  * Action:
  
  I do not understand where I am going wrong with this... It comes to the data preparation step that requires me to prepare the data before applying the techniques of modeling or algorithms... The next step might be to group the data, based on the time of the session, ip and the user agent of each session as well as the fields web_links visited by the user of the session.
  
  I would be really grateful for all entries on where I'm wrong and all the solutions for it!

  Good. Please close the message.

• Confusing function definition

  Hello

  Function definition is confusing me.

  I have run the statement.

  Select translate ('test', 't', ' a') of double

  It returns "EASA".

  That means it replaces 't' by 'a '.

  I have run this statement.

  Select double TRANSLATE('Q12345','12345','OK')

  It returns "MOK".

  It replaces '12345' with 'OK '.

  Now I run it,

  Select double TRANSLATE('Q12345','12345','')

  Returns a NULL value.

  But he should have come back 'Q' right?

  Exactly!  TRANSLATE returns a copy of its 1st argument, but with the n-th argument 2 character (' t ' in this case) changed the character n-th of the 3rd argument ("a" in this case).

  The 1st character of ' t ' is ' t ' and the 1st character 'a' is 'a', then all the t are replaced by 'the

  I made the same kind of mistake on the lines immediately below.]

  The 2nd character of "Q12345" is '1', and the 2nd character of 'OK' is 'K', and change all the 1 to ' K

  The 3rd character of 'Q12345' is '2', and there is no 3rd character in 'OK', so will be removed from all 2.  In other words, there is no 3rd character in 'OK', there will be no 2 accordingly.

  The same for the 4th, 5th and 6th characters of 'Q12345' (i.e., '3', ' 4 'and 5').

  TRANSLATE returns NULL if any of its arguments are NULL (and "with nothing between single quotes is equivalent to NULL).

  REPLACE ('Q12345', '12345', ") would return 'Q', but TRANSLATING is not identical to REPLACE.

• Edition (or replace) a function

  TLDR: I would like to change a line of code inside a function. Changes to the code and then executes the command in the FUNCTION to CREATE or REPLACE basically the same thing as editing function?
  
  
  A user receives the following when running a report in Business Objects error message. Here is the error message:
  

  ORA-06502: PL/SQL: digital error or value: number too high accuracy: ORA-06512: at "GUI. PR_OMIT', line 30: ORA-06512: at line 1:-6502

  so I opened the GUI function. PR_OMIT in Oracle SQL Developer and I think I found the problem. There is a SELECT INTO statement that attempts to save a 4-digit number in a variable NUMBER (2). I just want to change it to number 4. I can just make the change and click the button run? I guess this will "CREATE or REPLACE" function - which in this case, it would replace it.

  >

  Yes - which will replace the code. This must be done so that other users do not try to run the code.

• Error: 1021: duplicate function definition.

  Hi all

  First of all, let me start by saying that I know almost nothing about Flash.  I inherited a Web site maintenance project that has a rotating image Flash banner.  I managed to get the image fade-in / fade-out properly, but now I need to make these clickable images - link images to pages in the Web site.  I read a lot of posts here and went through the video tutorials.  I was able to get the first image map using this AS3 action:

  mars_btn.addEventListener (MouseEvent.CLICK, buttonClickHandler);
  function buttonClickHandler(event:MouseEvent): void {}
  navigateToURL (new URLRequest ("http://somewebsite/mars.php"));
  trace ("clicked");
  }

  However, when I try to make another clickable image using another instance of a button I get the error message:

  1021: duplicate function definition.

  I have a separate instance of a button with this AS3 action:

  jupiter_btn.addEventListener (MouseEvent.CLICK, buttonClickHandler);
  function buttonClickHandler(event:MouseEvent): void {}
  navigateToURL (new URLRequest ("http://somewebsite/jupiter.php"));
  trace ("clicked");
  }

  I'm obviously not understand how I'm supposed to do this so that I don't create a duplicate function definition.  Any help would be most appreciated.

  If you don't know anything about AS then the easiest just to rename the methods of the Manager to unique names

  mars_btn.addEventListener (MouseEvent.CLICK, MarchClickHandler);
  MarchClickHandler(event:MouseEvent) function: void {}
  navigateToURL (new URLRequest ("http://somewebsite/mars.php"));
  trace ("clicked");
  }

  jupiter_btn.addEventListener (MouseEvent.CLICK, jupiterClickHandler);
  jupiterClickHandler(event:MouseEvent) function: void {}
  navigateToURL (new URLRequest ("http://somewebsite/jupiter.php"));
  trace ("clicked");
  }

• Ampersand substitution in create or replace procedure statement

  Hi guys,.
  
  I wonder why my replacement ampersand works in a create or replace statement of the stored procedure.
  
  CREATE OR REPLACE PROCEDURE UPDATE_DIM_SALES AS
  
  
  Cancel the DEFINITION DimSales;
  Cancel the DEFINITION FactTable;
  SET DimSales = 'TESTTAB;
  SET FactTable = myfact;
  
  
  BEGIN
  *...*
  
  Error (5,20): PLS-00103: encountered the symbol "=" when expected as follows: =. (@ %; not null default range character)
  
  
  If I assign the value with: = I get the error "invalid table" thereafter for the statemnt of INSERTION:
  
  CREATE OR REPLACE PROCEDURE UPDATE_DIM_SALES AS
  
  
  Cancel the DEFINITION DimSales;
  Cancel the DEFINITION FactTable;
  SET DimSales: = ' x 2';
  SET FactTable: = ' x 1';
  
  
  BEGIN
  INSERT INTO & DimSales (column1, column2,...)
  
  Why not the ampersand substitution work in a stored procedure?

  No problem with the carpet. Display. But you don't need to create and drop them again. Simply create a time and refresh just before departure if necessary. I expect the creation and updating of points of view is fast comparibly. Also access to the seller_id should be indexed.

  Your original pl/sql block is slow due to several reasons. One might be that you agree to each line. Engage is an extremely slow process. He avoid as much as possible. Another part might be that you make all the changes of context of pl/sql. The obvious way to avoid this would be to BULK operations (bulk-select + Forall). It is not so difficult. The size of the collection must be limited to a lower amount.

  Best way would be to measure the performance of pl/sql parts using a tool such as DBMS_PROFILER. Then you can decide what part is slow and must be granted.

  A simple insert could be faster. Did you test that?

  example not tested

  INSERT /*+append */
  INTO &DimSales (K_Sales,REG,BVL,DS, VS,RS,GS,VK)
  (SELECT trim(leading '0' from RS||GS) ,REG, BVL,DS, VS,RS,GS,VK
  from &FactTable f
  join &testsales s on f.SellerNo =s.Seller_No;
  
  commit;
  

  You can run the other issues, but this is generally the fastest approach. Try to avoid the separate if possible. This requires a sort and will slow down the insert of a lot.

• Need help to create a conditional LOV function

  First off the coast to let put me the warning that I am not the right Wick informed in PL/SQL. I need to use the LOV conditional for a list of selection based on the user's role in this application.

  I created the 2 types required and tested the function with a simple select query and LOV works.
  
  However, I need the function to return values based on the user role. I know, it's probably the ugliest pl/sql, you may have seen yet ;) I hope that you guys can decipher the logic that I use. Obviously, this code does not validate.

• TDMS Create or Replace returns an error

  Step #26 under FPGA section implements the open or create TDMS files.

  It always returns error #7 of the PDM create or replace VI.  When you create a new file, it should not return error "file not found".

  You are receving error 7 the path of the file that you specify. Make sure you use the correct path to the file. If you still have problems is an article in the knowledge base that may shed more light on what goes wrong.

  Hello

  the owner of the procedure should the privilege of creating its own synonyms if i_nonactive_user is defined on its own behalf (this case has no interest), and he has the privilege to create ANY synonym in other... At first glance, I would say that this is not a good idea.

  Note: you can also save a job: no need to redefine a synonym to point to the same thing, so I would limit synonyms selected in the loop:

  FOR rec IN (SELECT u.synonym_name, u.table_owner, u.table_name

  U user_synonyms

  WHERE u.table_owner! = v_table_owner

  )

• Create or replace Index supported?

  I could type "create or replace index...". "and found that it worked.  Then I went looking for it or not "or replace" is supported the option for 'create index' and can't find anything that tells me that it is.  I don't want to use it if it is not supported.  Anyone know?  I'm using Oracle Database 11 g Release 11.2.0.3.0.

  There are some RDBMS that support certain types of logic for the index - but Oracle is not among them. CREATE or REPLACE can be used for certain types of objects, but not for the index.

• Creating a shopping cart function

  Hello

  Right... This is a bit of an odd.

  I need to create a shopping basket function in muse, I won't take all payments, all payments are made by phone (we handle contracts business phone, broadband, etc then you do a credit check before you can authorize a contract). Then... I want people to be able to add items to their "shopping cart" and proceed through an order page where they fill all their details and "place order." Their details then get submitted to us and the products they have chosen - no payment is taken.

  I am really struggling to find a solution, does anyone know what whether that might work? Or is it is not possible and I should start looking for a different solution.

  The best solution I have found so far is to create a subdomain and using something like shopify as my e-commerce store but just have produced £0.00?

  Any ideas are appreciated.

  Thanks guys,.
