• drop and re-create the table

  Hello
  
  I am very new to the Apex. Very basic SQL and pl sql.
  
  Two questions: -.
  
  First of all, I want to delete a table and then recreate the same table in a script (strange I know but it is purely a LOV table).
  
  Then, run the combined script when a user presses a button on a form in the published application.
  
  REPORTED

  Hi reported.

  The delay I was referring to that is that when you go on a database connection, it takes much longer for a long time as if it were local. Rather than create a local table, why don't you just make the LOV created through data binding? for example the LOV queries:

  SELECT DISTINCT surname display_value, surname return_value
  FROM CUSTOMER_TBL@DBLINK

• How to create the Table using the column Drag and Drop feature

  Hello:
  I'm new to Data Modeler tool Oracle SQL dev and would like to know if there is a way to create a new table by reusing existing columns or groups of columns. The idea is to maintain consistency and save time of table design. If the columns created previously can be reused and require, drag and drop column in the right pane, then only new columns must be created manually.
  
  Any thoughts on this will be appreciated.
  
  Thank you!

  Yes - just change the name of the model table in the script (t_name = "table_template") then save this new transformation for later use.

  I don't know how to apply only some of the tables. Seems like something you could do to a secondary view level?

  Perhaps someone else on the forum can advise how to change the script to work on a subview only instead of the whole model.

• Drop and re-create the index on the current table

  Hello
  
  I just have a few questions about the removal and creating indexes on a table that activates a lot.
  
  Let me explain first:
  
  The table is used by the application with the DML statements every 3 seconds and I want to do is to drop the indexes and re-create them.
  But Im worried about the consequences - what happens when I try to recreate the indexes and the table has an option rowlock/used by the application?
  
  P.S
  It's production environment - so I can't stop the application.

  A reconstructed index either Online or Offline.

  Online index rebuild features:

  ALTER INDEX REBUILD ONLINE;

  LMD is allowed on the base table
  It's relatively slow
  Base table is targeted for the new index
  Base table is locked in shared mode and DOF is not possible
  Intermediate table stores changes to data in the base table, during the rebuilding of indexes to update the new index later

  Offline index rebuild features:

  ALTER INDEX REBUILD. (Default)
  Does not refer to the base of the table and the base table is exclusively locked
  New index is created from the old index
  Not possible DML and DDL on the base table
  Relatively faster

  Now according to the guidelines of your comment, I created a simple OWA environment and run the code below. Now I get not found error of data

  ORA-01403: no data found
  ORA-06512: at line 23

  The error is caused the cookie is not found.

  The following is not valid - as there is no browser to receive the cookie:

  (owa_cookie). Send
  name-online "SESSION1"
  value-online '344433',
  expires => it sysdate + 2,.
  => path ' / '.
  );

  The following code must set the CGI environment - and add the cookie to the environment for the following code to read (as shown in the code example that I posted in the 2nd thread I talked to you):

  / * Initialization * /.
  OWA.cgi_var_name (1): = 'something ';
  OWA.cgi_var_val (1): = "other";
  OWA.init_cgi_env (1, owa.cgi_var_name, owa.cgi_var_val);
  / * End initialization * /.

  Of course, the following code will fail with a NO_DATA_FOUND there is no cookie.

  ourCookie: = owa_cookie.get('SESSION1');
  v_session: = ourCookie.vals (1);

  So it is not possible to create a true cookie and retrieve the value of CGI environment or apex not?

  Yes. But the web browser is non-existent. Then, you need create the CGI environment, which would have created the web server, before you call your allowed web code PL/SQL.

  In other words, if your initialization code of CGI should pretend that it is the web server, he received the call from web browser, it received the cookie (s) from the web browser - and now she needs to create the CGI (including cookies) environment for this web browser, and then call the procedure PL/SQL referenced by the browser in the URL, he argued.

• Create the cursor using dynamic query

  Hello
  
  I declare a query:

  How can I assign this cursor query?
  I tried, in vain.

  CURSOR l_cur IS l_query;

  Thanks for help on this.

  Hello

  You must use a REF CURSOR for that (there are a few examples in the Oracle documentation). Here is a code example:

  DECLARE
     TYPE EmpCurTyp IS REF CURSOR;
     emp_cv   EmpCurTyp;
     emp_rec  emp%ROWTYPE;
     sql_stmt VARCHAR2(200);
     my_job   VARCHAR2(15) := 'CLERK';
  BEGIN
     sql_stmt := 'SELECT * FROM emp WHERE job = :j';
     OPEN emp_cv FOR sql_stmt USING my_job;
     LOOP
        FETCH emp_cv INTO emp_rec;
        EXIT WHEN emp_cv%NOTFOUND;
        -- process record
     END LOOP;
     CLOSE emp_cv;

• Skip a page and print on the back using PL/SQL?

  Morning people,
  Greetings from Toronto. I have a report that was written in PL/SQL (not Oracle or SQL reports * most) and its job very well. The totals are correct and I have two sets of totals. A total for the Department in particular and, finally, a total of the entire company. The user of course wish the two totals for each same Department if he or she chooses to print only service (using a setting). So, it's not a problem.
  
  I just want to be the total final (company-wide) on the last page. Now, it is relatively simple in the reports of the Oracle, as well as SQL * more reports where I could probably use Skip. Y at - it a simple way to do or what I must count lines based on pagesize? So, for example, if the size of my page is 53 and my last record Department stops at line 35, I have to insert empty rows using UTF_FILE. Put_line in a FOR loop. This method would probably work ut I wonder if there's ways more interesting or easier to do?
  
  This issue does not have to decide at this moment and I know its Monday. :-) Any help would be appreciated.

• Missing cells in the table of dynamic columns

  Hello
  
  I am creating a table using dynamic columns. Here's an example simplified data that I use:
  
  < sales >
  ... < drive >
  ... Honda < brand > < / brand >
  ... < color > green < / color >
  ... < / car >
  ... < drive >
  ... Nissan < brand > < / brand >
  ... < color > blue < / color >
  ... < / car >
  ... < drive >
  ... Honda < brand > < / brand >
  ... < color > blue < / color >
  ... < / car >
  < sales >
  
  I am grouping the brands for the lines, and I want a number of colors as my dynamic column. I find myself with a table that looks like this:
  
  ----------------------------------------------------------------------------------
  Brand | Blue | Green |
  ----------------------------------------------------------------------------------
  Honda | 1. 1.
  ----------------------------------------------------------------------------------
  Nissan | 1
  --------------------------------------------------------
  
  Since there is no green Nissan, a cell not created so I find myself with a hole in my table. Ideally, I would want a cell containing 0 to be in this space.
  Is it possible, or to all the least have a cell in this space, so I did not have a table with gaps?
  
  Thank you!

  If you have saved the file name in the database, it's pretty simple.

  echo '';
  

  Is the same for the box:

  echo '';
  

  If you have saved the image file in the database, it is much more complicated. I recommend you store only the file name in the database.

• Create the Table as and hybrid columnar Compression

  I'm looking to connect to tables help to create the table as I had a question about columnar Compression hybrid. For the test, I found that the uncompressed daata will be approximately 10 to and compressed data will be around 1 TB. I anticipate compress the table when the table to create as an instruction and wanted to know in what order Oracle forge do compression, that is, the table will be created then Oracle will compress the data or will the compressed table that the table will be created. The motivation behind the question is to see how much storage I need to complete the operation.
  
  Thank you

  If you are using
  create table xxx compress for query high what to choose...

  While the data will be compressed before insertion, so in your case, it will use about 1 TB of disk space
