• How to perform this procedure and get the result?

  I created a procedure, the source code for the same thing is provided below.

• PLSQL function to return the result of the query

  Dear all,

  Oracle Database SE1 11.2.0.1

  I need to create a plsql function which should accept SQL as a parameter, execute it and return the result set.

  Is this possible?

  Be careful - results games indicate a set of data stored in memory. This is not what are sliders. This isn't how Oracle should be used.

  Imagine that you implement such a result set function - which, on average, requires 1 MB of memory (private server) to store the results of the SQL query. A 100 users mean a 100 MB of memory required server. This is not suitable. Not at all. Never.

  The correct back 'thing' is a handle to SQL cursor (called a ref cursor in this case). A SQL cursor is a "program" - that the appellant runs via the fetch command and generates one or more lines accordingly. Appellant repeatedly runs this slider through calls to fetch until this slider found and returns all rows affected (using consistent readings).

  If you want an abstraction interface that the client can call via PL/SQL code in the database, so this crafting optimal SQL interface, creates the SQL cursor and returns the handle of the cursor (via the ref cursor data type) to the client.

• Function that returns the results of a select statement

  Hello
  
  I would like to create a feature on the famous HR Departments oracle table to select * from him. I don't know how to do it.
  
  Is someone can help me?.
  
  Thank you

  Oracle stored functions cannot return result sets directly but can return the REF CURSOR. Please read [optimize result set retrieval using ODP.NET and Ref Cursor | http://www.oracle.com/technology/pub/articles/mastering_dotnet_oracle/williams_refcursors.html] which gives complete examples in PL/SQL for the side Server and VB.

  Hi Ben,

  Decode is a function SQL and SQL ignores Boolean values. If the Analyzer does not provide the< sign="" and="" expects="" a="" right="" parenthesis="" at="" that="">

  You can use something like:

  case
    when date_expired < sysdate then ...
    when date_expired = sysdate then ...
    else ...
  end
  

  Kind regards
  Rob.

• Procedure to take income data set and return the result set

  Hi all
  
  I have a situation where there will be a 'standard' set of data (source_data below), and I need to get information on outcomes for certain groups of customers (client_data for example). As SQL right it would be very easy (see below) - real world problem is a bit more complicated. However, what I would do is set up a procedure so that I can pass on my data of client variables and it will spit back on a set of data that is identical to the output of the given SQL.
  
  A pointer in the right direction would be appreciated. If I could 'pass customer data' as a string that contains an SQL query, which would be even better, for example
  
  GetResults ("select client_id, min (whatever_date) from some_client_data which...", MyOutputRefCursor?)
  

  create table source_data
  (client_id integer,
  tdate date,
  amount number(6,2));
  
  create table client_data
  (client_id integer,
  critical_date date);
  
  insert into source_data values(1,to_date('20090104','yyyymmdd'),1000);
  insert into source_data values(1,to_date('20100104','yyyymmdd'),2000);
  insert into source_data values(1,to_date('20110104','yyyymmdd'),3000);
  insert into source_data values(1,to_date('20120104','yyyymmdd'),4000);
  insert into source_data values(2,to_date('20090104','yyyymmdd'),5000);
  insert into source_data values(2,to_date('20090604','yyyymmdd'),1000);
  insert into source_data values(2,to_date('20100104','yyyymmdd'),2000);
  insert into source_data values(3,to_date('20091004','yyyymmdd'),3000);
  insert into source_data values(3,to_date('20091104','yyyymmdd'),4000);
  insert into source_data values(4,to_date('20090104','yyyymmdd'),5000);
  insert into source_data values(4,to_date('20090604','yyyymmdd'),2000);
  
  insert into client_data values(1,to_date('20110104','yyyymmdd'));
  insert into client_data values(2,to_date('20090604','yyyymmdd'));
  
  
  select c.client_id,
    sum(CASE WHEN tdate < critical_date then amount else null end) used_before,
    sum(CASE WHEN tdate >= critical_date then amount else null end) used_after
  from source_data s
  inner join client_data c on s.client_id = c.client_id
  GROUP BY c.client_id;

  Thank you

  Hello

  You can do this with a view. Make settings of the view a global temporary table:

  create GLOBAL TEMPORARY table client_data
  (       client_id       integer
  ,     critical_date      date
  )
  ON COMMIT PRESERVE ROWS
  ;
  

  Then, you can create a view based on your real of the table and the parameter array:

  CREATE OR REPLACE VIEW     special_clients
  AS
  select c.client_id,
    sum(CASE WHEN tdate < critical_date then amount else null end) used_before,
    sum(CASE WHEN tdate >= critical_date then amount else null end) used_after
  from source_data s
  inner join client_data c on s.client_id = c.client_id
  GROUP BY c.client_id;
  

  Because the table of parameters is a global temporary table, each session will have its own private copy of the table of parameters and therefore his own private version of the view.

• Tax calculation based on the user in the box input and displaying the result.

  Thanks to WhyIsThisMe for starting me on my first draft script & Jono! I'm almost there with my purchase requisition form (90% manufactured from the tutorial).  Everything works except for the taxable column

  

  I can't understand the correct syntax to check the value of the checkbox in the column taxable and then do the math for the tax based on user input in the field % tax

  (total * stateTaxPercent / 100)

  Essentially, I want to make the calculation only the taxable = 1, and then display the cumulative tax in the tax field.

  Should I use mouseup as trigger to perform the calculation of the tax and save the result as a variable and displays the variable in the tax field? Then if another taxable box gets checked, I could add the new calculation of the variable. Not sure whether in an elegant way to get there.

  ?
  

  I would put the following text in the change event of each taxable check box (in formcalc):

  If ($ == 1) then

  tax = tax + (amount * 0,0825)

  ElseIf ($ == 0) then

  tax = tax - (quantity * 0,0825)

  endif

  (where 'tax' is what you called your total tax box and the 'amount' is what you called your box of price).

  Double check with a magnifying glass and a good lighting that nothing has been slain. Then, try insertion and withdrawal of your headphones a couple of times.

• How to write a function to estimate the number of rows returned SQL?

  How to write a function to estimate the number of rows returned SQL through SQL Execution Plan?
  My idea is
  Call dbms_sql.parse to create the SQL PLAN, then ask the PLAN for the number of estimated return lines.
  But how to get SQL plan through "id cursor?
  Thank you.

  You can use EXECUTE IMMEDIATE to explain plan statement. About the STATEMENT_ID generation, it could be anything. Even a SYSTIMESTAMP cast as TANK would work.

• How to get the query of the region "PL/SQL function body returns the query string"?

  : P49_QUERY: = v_return_query;
  Return v_return_query; < / pre >
  
  to save the return on hidden item P49_QUERY string, but it does not work. I get the error message: ERR-1002 cannot find the item for the "P49_QUERY" element ID in the application '4000 '.

  If you need to make reference to a page element in the block then you can use this type of control to avoid having to use generic column names:

  if apex_application.get_current_flow_sgid(:APP_ID) = apex_application.get_sgid then-- runtime  :P9_SQL := vSQL;else-- design time  null;end if;
  

  But if all you want to do is capture the SQL debugging you can take all the references element in the block and use the insert statement (in a debug table) as I showed earlier.

  -- My types
  create or replace

  create or replace

  Hello

  Welcome to Oracle and XML DB!

  After reviewing the documentation of oracle on the generation of xml data in the database, I managed to select normal tables and return a result xml exactly as I want:

  Have you also read about the SQL/XML functions?
  You don't have to create objects of type SQL to generate XML data.

  Using only XMLElement, XMLAgg, XMLAttributes, etc., you should be able to generate any kind of structure complex relational data and with total control over the names (which you don't have with the types of objects).
  Your example can be rewritten to:

  SELECT XMLElement("Parent",
           XMLAttributes(p.id as "Id")
         , XMLElement("Children",
             (
               SELECT XMLAgg(
                        XMLElement("Child",
                          XMLAttributes(
                            c.id as "Id"
                          , c.name as "Name"
                          )
                        )
                      )
               FROM child c
               WHERE c.parent_id = p.id
             )
           )
         )
  FROM parent p
  WHERE p.id = :parent_id ;

  Do I have to return the data as xml?

  Yes.
  Define the return as XMLType data type:

  )
  RETURN XMLTYPE
  AS
      L_RESULT XMLTYPE;
  BEGIN

                          XMLElement("Child",

               )
             )
           )
