  How to convert the hierarchical query of SQL Server (CTE) to Oracle?
  
  WITH cte (col1, col2) AS
  (
  SELECT col1, col2
  FROM dbo. [tb1]
  WHERE col1 = 12
  UNION ALL
  SELECT c.col1, c.col2
  FROM dbo. [tb1] AS c INNER JOIN cte AS p ON c.col2 = p.col1
  )
  DELETE one
  FROM dbo. [tb1] AS an INNER JOIN b cte
  ON a.col1 = b.col1

  Hello
  Something like this maybe:

  DELETE FROM dbo.tb1 a
   WHERE EXISTS (
    SELECT 1
      FROM dbo.tb1 b
    WHERE a.co11 = b.col1
        AND a.col2 = b.col2
     START WITH b.col1 = 12
    CONNECT BY b.col2 = PRIOR b.col1)
  

  Although you need to do here is to check that CONNECT it BY SELECT, returns records you wait first, then the DELETION should work too.

• How to exclude records from the outer query

  My apologies if this was requested. I find no answer. I don't know what terminology should be for that matter.

  In simple terms, I want to use the custom in where clause to select records. Problem is function will fail if applied to old records, as there was no relevant data. I have logic to exclude old records, but the problem is that this process running function before old records are excluded. I tried an inside view to exclude records before their passage in the outer query, but this does not resolve the situation.

  Below shows high level required

  Select x

  tab

  where (condition to exclude the old records)

  and function (tab.y) = value

  If I rewrite as below, still have the problem. Was hoping to exclude former records apply before function.

  Select inn.x

  Of

  (select x,

  There

  tab

  where (condition to exclude the old records)) inn

  where function (inn.y) = value

  Thank you

  Hello

  Including ROWNUM in the result set of the query-void will force the subquery to do first:

  Select inn.x

  Of

  (select x,

  There,

  ROWNUM AS r

  tab

  where (condition to exclude the old records)

  ) inn

  where the function (inn.y) = some_value

  Since ROWNUM depends on the WHERE clause of the query-sup, the query cannot be rewritten to the main to do first query WHERE clause.

• How to wear the formhandler query parameter in jsp

  I know that its very stupid question, but I don't get a query parameter. I don't know what mistake I make.

  Here is my code snippet:

  I created a formhandler

  
  

  LoginFormHandler.java

  public boolean handleLogin (request, response DynamoHttpServletResponse DynamoHttpServletRequest)

  throws IOException, ServletException {}

  Here the value of the user ID is available I checked using DD

  request.setParameter ("userId", username);

  handleFlag = checkFormRedirect (getCreateSuccessURL (), getCreateFailureURL(), request, response);

  in CreateSuccessURL it redirects to LoginSuccess.jsp

  LoginSuccess.jsp

  < %

  DynamoHttpServletRequest drequest = ServletUtil.getDynamoRequest (request);

  % >

  value: < %=drequest.getParameter("userId") % >

  Once that LoginSuccess.jsp the display is showing the value null of userId

  Please let me know how to wear the setting the Manager of jsp.

  Application settings will be lost in the success page because the formhandler send a redirect to the success page.

  It will be new demand for the success page.

  As suggested, or you will need to put this in formhandler, or cookie or in the url

• How to get the inline query which is drawn from the TAB specific Application.

  Hi all I use 10.2.0.4.0 oracle version.
  
  I want to capture the sql that is raised in my prod database when an applicaton tab is hit as it takes about 5 minutes for the tab to be loaded. So is it possible, for the inline sql, which is the origin of the problem, directly from the prod environment.
  
  (Note: I looked through the browser session in PROD DB for the query, but there, I found a lot of meetings and a lot of requests, I do not know how to distinguish the session being created by the specific tab I hit).

  the origin of the problem, directly from the prod environment.

  Please, please tell us that you have a Test environment? Log into that, then run a trace.
  No doubt you can either descend all test for a few miinutes and/or
  easily distinguish sessions on your Test System? That's exactly what the test
  the environments are for.

  The SQL execution will be the same - you can go try to find
  the root cause of the problem.

• How to make the simple query for this scenario... ?

  Hello:
  
  Dummy table provided for simplicity.
  
  It's my database table (Table_A)
  
  Date1 | Plane1 | Category | Duration | Fees
  01/01/2011 | A | Gold | 5. 2
  01/01/2011 | C | Money | 4. 11

  01/01/2011 | D | Gold | 2. 4
  01/01/2011 | B | Gold | 3. 5
  01/01/2011 | A | Money | 4. 8
  01/01/2011 | B | Gold | 1. 3
  
  I need to write a query to get the result below:
  
  Date1 | Plane1 | Sum_Duration | Sum_Charge | Sum_Gold_Duration | Sum_Gold_Charge | Sum_Silver_Duration | Sum_Silver_Charge
  01/01/2011 | A | 9. 10. 5. 2. 4. 8

  SELECT Date1,
  base1,
  Sum (Duration) Sum_Duration,
  Sum (load) Sum_Charge
  FROM TABLE_A
  GROUP BY date1, rarateplan
  
  But I need to know how to get the rest of the columns (i.e. Summary according to categories; from 5 to 8 columns)? Is this can be done in a single query without writing subqueries?
  
  Please let me know, (with code), the best way.
  
  Thank you-
  Tanvir

  Use like this:

  SELECT Date1,
  base1,
  Sum (Duration) Sum_Duration,
  Sum (load) Sum_Charge,
  SUM (decode(Category,'Gold',duration,0)) Sum_Gold_Duration,
  SUM (decode(Category,'Gold',charge,0)) Sum_Gold_charge,

  SUM (decode(Category,'Silver',charge,0)) Sum_Silver_charge
  FROM TABLE_A
  GROUP BY date1, rarateplan

  I tried to use COLLECT in BULK instead of a cursor for loop, but it did not help.
  When I took the select query separately and executed with a value of the sample, and then he gave the results in a Flash of a second.
  
  All tables have primary key index.
  Any ideas what can be done to make this code more efficient?

• How to get the SQL query running of af: search?

  I use JDeveloper 11.1.2.3.0. I have a page where I've set up an af:query and an array of result. The problem is that I can't get the exact query that is used during the execution of this component in a managed bean method. Is it possible to get the query string that is run within the af: query?

  Thank you

  Hello

  Method of the ViewObject getQuery() returns what you need;

  You can replace the executeQueryForCollection(), and prior to calling super, you can print the result of getQuery() method:

  public void executeQueryForCollection (rowset Object,

  Object [] params,

  {int noUserParams)

  System.out.println ("SQL =" + getQuery());

  call the super method here...

  }

• Error giving a subquery, but with the outer query, it gives no error.

  Hello
  The following query gives error "ORA-00979: not a GROUP BY expression" (I know to use the filter condition in the WHERE clause, but for reasons explaining the problem, I use the HAVING clause)
  
  SELECT DeptNo

  But when I use it as a subquery in as long as below, the query will run successfully (resultset may be wrong).

  Sort of philosophical question. But you're right, this behavior can be misleading.
