• The dynamic LOV PL/SQL syntax help

  Hello
  
  I am trying to create a dynamic lov pl/sql Oracle Apex 3.2 on 11 g. I'm having some trouble with the syntax of the statements below and I would be grateful for any suggestion.
  

  DECLARE
  BEGIN
  
  IF :p3_current_a_workshop != 0 THEN
  RETURN
  'select distinct workshop_title ||':  '  || presenter_name ||'    $'|| workshop_fee display_value, workshop_id return_value 
  from WORKSHOP
  where session_time = 'A'
  and workshop_status = 'Open'
  or workshop_id = :p3_current_a_workshop
  order by 1';
  
  ELSE
  RETURN
  'select distinct workshop_title ||':  '  || presenter_name ||'    $'|| workshop_fee display_value, workshop_id return_value 
  from WORKSHOP
  where session_time = 'A'
  and workshop_status = 'Open'
  order by 1';
  
  END IF;
  EXCEPTION
          WHEN OTHERS THEN
              HTP.PRN('ERROR'||SQLERRM);          
  END;

  I'm trying to shape the code above out of the example given by apex:
  

  A function that returns a SQL query with two columns:
  
  IF :MY_ITEM='10' THEN
    RETURN 
    'SELECT ename, empno 
  FROM  emp 
  WHERE depno = 10 
  ORDER BY 1';
  ELSE

    'SELECT ename, empno 
  FROM emp 
  WHERE depno = :my_item 
  ORDER BY 1';
  END IF;

• Design of the dynamic schema through SQL

  Hi all
  
  Is it possible to design a dynamic schema using SQL?
  Documents or links is greatly appreciated.
  
  Thank you

  Hello

  Sorry, I don't get you. Design of a scheme is more than dynamic SQL, you must think of tables, relationships, constraints, standardization, etc..

• Performance issues with dynamic action (PL/SQL)

  Hello!

  
  I have problems of perfomance with dynamic action that is triggered on click of a button.

  I have 5 drop-down lists to select the columns that users want filter, 5 drop-down lists to select an operation and 5 boxes of input values.

  After that, it has a filter button that submits just the page based on the selected filters.

  This part works fine, the data are filtered almost instantly.

  After that, I have 3 selectors 3 boxes where users put the values they wish to update the filtered rows and column

  There is a update button that calls the dynamic action (a procedure which is written below).

  It should be in a straight line, the issue of performance might be the decoding section, because I need to cover the case when the user wants to set a null (@), and when it won't update the 3 columns, but less (he leaves ").

  That's why P99_X_UC1 | ' = decode(' ||) P99_X_UV1 |', "«,» | P99_X_UC1 ||',''@'',null,'|| P99_X_UV1 |')

  However, when I click finally on the button update, my browser freezes and nothing happens on the table.

  Can anyone help me solve this problem and improve the speed of the update?

  Kind regards

  Ivan

  Hello Ivan,.

  I don't think that the decoding is relevant performance. Perhaps the update is suspended because another transaction has changes that are uncommitted to any of the affected rows or where clause is not quite selective and has a huge amount of documents to update.

  In addition - and I may be wrong, because I only have a portion of your app - the code here looks like you've got a guy here huge sql injection vulnerability. Perhaps you should consider re - write your logic in the static sql. If this is not possible, you must make sure that the entered user contains only allowed values, for example by P99_X_On white list (i.e. to ensure that they contain only values known as 'is', ')<', ...),="" and="" by="" using="" dbms_assert.enquote_name/enquote_literal="" on="" the="" other="" p99_x_nnn="">

• Examination of dynamic cursor and SQL performance

  Hello world
  
  I'm a researcher on internet forums and oracle for what is best for my case.
  
  
  I tried to rebuild indexes. I had two methods, both works very well, but I'm looking for which is preferable from the point of view of performance
  
  1 - the use of cursor as in the link below.
  
  http://www.think-forward.com/SQL/rebuildunusable.htm
  
  
  2 - using dynamic SQL, that generated the script file, then run it.
  
  coil rebuildall.sql
  Select "change the index ' |" owner: '. ' || index_name |' rebuild online; '
  from dba_indexes where status = "UNUSABLE."
  spool off;
  
  @rebuildall.sql
  
  
  Thanks in advance. Your help is appreciated.

  In both cases, that you use dynamic SQL statements, I think that there is no difference in terms of performance, use the method you feel most comfortable

  In all cases, you can follow the timestamps (time is set on & set timing on) and connect the outputs

  Nothing different from what Anurag has shown above.
  But you will need to consider a few things.
  (1) since it is possible it is not a must to use
  (2) it is considered to be a poor design where in it need to create tables on the fly.
  (3) whether it is absolutely mandatory. If you can give us an idea of your condition. I don't know that the gurus here can give you suggestions
  (4) this kind of design will be will lead you into problems sooner or later for sure

• Content of dynamically looped for SQL Insert

  I have a form that is created when a user selects the number of lines they need ultimately to decide on the number of records they will be insert into a SQL database. After there include the information in the form and send it, I have a page that contains the SQL query. I'm looking for at the request of the same number of rows as there are in the table in a loop. However, I can't get the query to run because of double variables. For example in a form simple submission if I had a form called 'Name' text field, it would be to insert in the database "#form.name # If the user has selected 10 lines, I would need to insert each line like "#form.name1 #", "#form.name2 #", etc.. If my variable for the number of lines is 'I' so my whole variable for the loop would be "#form.name #i # ' does not. Hope, it is not too complicated, and any help would be appreciated.

  Who did it! Thank you very much!

• Use Dynamic Actions with pl/sql, calling a javascript alert function

  Hello
  
  I use Apex 4.0.1.00.03 with IE7.
  
  The problem I have is:
  
  I am converting an Oracle Forms application that has a lot of logic in it. In the application forms, it is a pl/sql function, based on a If/else condition call a popup alert box, which displays a warning message. He called pl/sql functions that return raising to the IF statement.
  
  Example of pl/sql code:
  
  If check_records() > 0 Then
  message to the alert box
  ElsIf TypeA_record then
  message to the alert box
  On the other
  message to the alert box
  End If;
  
  I need to replicate this functionality to the Apex 4. I tried to create dynamic Action on a page element, using a pl/sql function, however, when I call the popup javascript, this code not popup an alert box. I need the pl/sql to be run when the element of the page changes, not when the page is sent.
  
  The code I used to test the pl/sql code, which does not work in dynamic Actions > pl/sql is:
  
  Begin
  HTP.p ("< script type =" text/javascript"> '");
  HTP.p ("alert ("today runs javascript code!");"
  );
  HTP.p ("< /script >");
  End;
  
  I need to create a pl/sql function that can do alert areas based on an IF condition.
  
  Could someone point me in the right direction? Using dynamic shares the best way forward? I need to trigger on a page element, change the value.

  Works fine now.
  In the javascript code, I changed:

  get.addParam ('x 01', $v ('P105_PREP_TYPE'));

  by

  get.addParam ('x 01', $v ('P1_PREP_TYPE'));

  P1_PREP_TYPE is the correct name of the element.
  Now when I choose the OTHER, 1 message.

• Tables created in a stored procedure cannot be used with dynamic SQL? The impact?

  There is a thread on the forum which explains how to create tables within a stored procedure (How to create a table in a stored procedure , however, it does create a table as such, but not how to use it (insert, select, update, etc.) the table in the stored procedure.) Looking around and in the light of the tests, it seems that you need to use dynamic SQL statements to execute ddl in a stored procedure in Oracle DB. In addition, it also seems that you cannot use dynamic SQL statements for reuse (insert, select, update, etc.) the table that was created in the stored procedure? Is this really the case?
  
  If this is the case, I am afraid that if tables cannot be 'created and used"in a stored procedure using the dynamic SQL, as is the case with most of the servers of DB dynamic SQL is not a part of the implementation plan and, therefore, is quite expensive (slow). This is the case with Oracle, and if yes what is the performance impact? (Apparently, with Informix, yield loss is about 3 - 4 times, MS SQL - 4 - 5 times and so on).
  
  In summary, tables created within a stored procedure cannot be 'used' with dynamic SQL, and if so, what is the impact of performance as such?
  
  Thank you and best regards,
  Amedeo.

  Hi, Frank.

  Thank you for your response. I understand that the dynamic SQL is required in this context.

  Unfortunately, I am yet to discover "that seeks to" using temporary tables inside stored procedures. I'm helping a migration from MySQL to Oracle DB, and this was one of the dilemmas encountered. I'll post what is the attempt, when more.

  In Oracle, we use [global temporary Tables | http://www.psoug.org/reference/OLD/gtt.html?PHPSESSID=67b3adaeaf970906c5e037b23ed380c2] aka TWG these tables need only be created once everything like a normal table, but they act differently when they are used. The data inserted in TWG will be visible at the session that inserted data, allowing you to use the table for their own temporary needs while not collide with them of all sessions. The data of the TWG will be automatically deleted (if not deleted programmatically) when a) a commit is issued or b) the session ends according to the parameter that is used during the creation of the TWG. There is no real need in Oracle to create tables dynamically in code.

  I noticed that many people say that the "Creation of the tables within a stored procedure" is not a good idea, but nobody seems necessarily explain why? Think you could elaborate a little bit? Would be appreciated.

  The main reason is that when you come to compile PL/SQL code on the database, all explicit references to tables in the code must correspond to an existing table, otherwise a djab error will occur. This is necessary so that Oracle can validate the columns that are referenced, the data types of those columns etc.. These compilation controls are an important element to ensure that the compiled code is as error free as possible (there is no accounting for the logic of programmers though ;)).

  If you start to create tables dynamically in your PL/SQL code, so any time you want to reference this table you must ensure that you write your SQL queries dynamically too. Once you start doing this, then Oracle will not be able to validate your SQL syntax, check the types of data or SQL logic. This makes your code more difficult to write and harder to debug, because inevitably it contains errors. It also means that for example if you want to write a simple query to get that one out in a variable value (which would take a single line of SQL with static tables), you end up writing a dynamic slider all for her. Very heavy and very messy. You also get the situation in which, if you create tables dynamically in the code, you are also likely to drop tables dynamically in code. If it is a fixed table name, then in an environment multi-user, you get in a mess well when different user sessions are trying to determine if the table exists already or is the last one to use so they can drop etc. What headache! If you create tables with table names, then variable Dynamics not only make you a lot end up creating (and falling) of objects on the database, which can cause an overload on the update of the data dictionary, but how can ensure you that you clean the tables, if your code has an exception any. Indeed, you'll find yourself with redundant tables lying around on your database, may contain sensitive data that should be removed.

  With the TWG, you have none of these issues.

  Also, what is the impact on the performance of the dynamic SQL statements in Oracle? I read some contrasting opinions, some indicating that it is not a lot of difference between static SQL and SQL dynamic in more recent versions of Oracle DB (Re: why dynamic sql is slower than static sql is this true?)

  When the query runs on the database, there will be no difference in performance because it is just a request for enforcement in the SQL engine. Performance problems may occur if your dynamic query is not binding variable in the query correctly (because this would cause difficult analysis of the query rather than sweet), and also the extra time, to dynamically write the query running.

  Another risk of dynamic query is SQL injection which may result in a security risk on the database.

  Good programming will have little need for the tables of dynamically created dynamically or SQL.
