• How to create a LOV where he is forced by another field

  I'm trying to figure out how to get a LOV to be limited by the value of a column
  
  A hypothetical example (the real app is quite different):
  
  I have 2 tables
  clientInfo, with fields fname lname, age, city, postal code
  In another table called cityZip I zip & city
  
  So I create a report on a table shape
  Select fname lname clientInfo, age, city, postal code
  
  This generates a form of beautiful table, an entry for each client... but I want the user to go to the bottom of the selectList representing the city column and select the city for each record in the table.
  
  So I created a Select list (query based LOV),
  I tried
  SELECT DISTINCT (code |) ' ' || d of the city), zip_KEY r
  from cityZip where cityZip.zip =: zip code
  
  The problem is that the use of the postcode in the LOV query does not contain the zip code of the current record value, so it does not work! Does anyone have an idea how this could be done?

  Hello

  The problem is that the data in your report are not contained in APEX elements in your page. Try to look at the combination of the form & report and put your selection list in the form. When you click 'Edit' on a line, that data fills out the form. You will have then the information limit the query for your LOV.

  Good luck

  Both operands for AS are supposed to be strings. Do not try to use a DATE, such as SYSDATE, with AS.

  do not return only documents not expected

  SELECT ITEM_NAME, available_date FROM TEMP WHERE available_date >= SYSDATE ;
  

  It returns the results I expect.
  If you'd say what results you expected, could someone help you wite a query to get.

  Assuming that 1 second elapses between the time "ITEM4" is inserted and that 2nd query execution, then, running, available_date will be 1 second less than SYSDATE, so it shouldn't be included.
  If you want to find lines that are on the same calendar day as SYSDATE or later, then use

  WHERE    available_date >= TRUNC (SYSDATE)

• How to define a WHERE clause of the subquery in a bean managed?

  Hi people,
  
  is it possible to define the place where clause of a subquery in a bean managed?
  For example, it is more SQL charly:
  
  SELECT * FROM
  (SELECT Person.Name
  OF the person)
  
  To change or add a WHERE clause, I use following code for the 'viewObject: view
  
  String whereClause = "ROWNUM < =: numberOfRows;
  viewObject.setWhereClause (whereClause);
  
  viewObject.defineNamedWhereClauseParam ("numberOfRows", null, null);
  viewObject.setNamedWhereClauseParam ("numberOfRows", new Number (100));
  
  AttributeList myattr = this.getNamedWhereClauseParams ();
  viewObject.setNamedWhereClauseParams (myattr);
  
  For example, this code works well for the first SELECT statement limit the output to the first 100 results. But how do I add a WHERE clause of the subquery in a managed bean? For example, when I want to limit the names of people that begin with the letter "A"?
  The query should look like this:
  
  SELECT * FROM
  (SELECT Person.Name
  OF the person
  WHERE Person.Name LIKE 'A %')
  
  Anyone know more?
  
  Thank you!

  Put a variable binding in your query, something like:

  where (: bv is null) or (xxx love: bv)

• Creation of a where clause clause in the LOV query box

  Hi guys is any able to help me with this one

  I have a page in my application where there down LOV down now values this menu drop-down comes from a table that looks like this

  users_for _form_TBL

  E_MAIL	Name of the vendor
  [email protected]	Oracle
  [email protected]	SAP
  [email protected]	IBM
  [email protected]	Oracle
  [email protected]	Intergraph

  So my syntax for the LOV I mentioned looks like this

  Select PROVIDER as display_value, SELLER as return_value

  of form_user_tab where email =: APP_USER

  order by 1;

  
  

  so if [email protected] connects to the application and to make a selection on the LOV it would only show suppliers compared to his E_MAIL like oracle, sap, IBM , and then he clicks the submit button on the page then the seller that he chose is inserted into another table. What I did on the table of insertion has been to create a trigger that after inserting a seller the trigger inserts a 1 in a column called assessed.

  What I did after that is add a select statement in the where clause of the LOV so that she would check in the table insert if this seller had been chosen before and not show them again to be selected my syntax, the second time around in the SQL query box has been

  Select PROVIDER as display_value, SELLER as return_value

  to users_for _form_TBL where email =: APP_USER

  and (select "seller", "ASSESSD' of _tbl inserted is null);

  order by 1;

  But im getting an error of ideas guys. Thank you

  im still get and error is the where the clause allowed in the second select statement

  He still has basic syntax errors. You posted 4 different "table names" whose only in the first query is valid so far. That can not see your database, I don't know what really is the name of these tables, and to what extent these is wrong helps your problem.

  I can tell that you are looking for:

  select
      u.vendor display_value
    , u.vendor return_value
  from
      users_for_form_tbl u
  where
      u.e_mail = :app_user
  and not exists (select null from inserted_tbl_imp i where u.vendor = i.vendor)
  order by
      u.vendor
  

  but the table names could be something else...

• [ADF, JDev12.1.3] How to set a variable to bind a VO (where clause) in a managed bean?

  Hallo,

  I have a request based on VO.

  The query contains a where clause clause and a bindi variable.

  In a managed bean I would like to access the iterator of VO setting the value of the bind variable and read the result.

  I found this code it is good start, but I do not know how to set the variable binding.

  BindingContext bctx = BindingContext.getCurrent();
  BindingContainer bindings = bctx.getCurrentBindingsEntry();
  DCIteratorBinding iter = (DCIteratorBinding ) bindings.get("MyVO1Iterator");
  iter.execute();
  
  
  

  You kindly help me?

  Also, I would like to know if it is generally advisable to use VO directly in controlled beans or whether it would be best to create in the AppModuleImpl methods that do this and return the result.

  In my case for example of the VO will return max 1 plug so I'm in doubt, if the creation of a method in the AM that returns a custom class, which attributes contain values of the line of VO.

  Sorry if these questions may seem artificial, but I am a beginner, I have many doubts and so I would be happy to receive some tips regarding best practices.

  Thank you

  Federico

  You can use:

  iter.getViewObject().setNamedWhereClauseParam("yourBindVar", value);
  

  Note that this approach is used if you have bind variable in the where clause.

  To set variables bind to ViewCriteria, you must use VarableValueManager.

  This post may be useful for you: binary: how to set the Bind variable values at run time?

  Also, I would like to know if it is generally advisable to use VO directly in controlled beans or whether it would be best to create in the AppModuleImpl methods that do this and return the result.

  You must set "use VO directly.

  For example, from the point of architecture, is probably best to use the method in the model project which will set the bind variable and execute the query.

  Or you can use the ExecuteWithParams operation in your the view layer.

  In my case for example of the VO will return max 1 plug so I'm in doubt, if the creation of a method in the AM that returns a custom class, which attributes contain values of the line of VO.

  Not to complicate your life

  All VO lines are represented as ViewRowImpl class if you already have "custom class".

  Finally, you can generate your own ViewRowImpl class if it is necessary for this.

• [JDev ADF] How is made the ' where clause ' default display criteria "all searchable attributes?

  Hallo,
  

  
  

  on a view object, I create my view of the criteria customized; I'm going to use it to create a "query with the table panel.

  I wish that his beahviour, when I use it to create a "query with the table panel", corresponds to that of "attributes searchable all.

  Unfortunately I'm having some trouble in his creation and I would like to see how is made the "object view where Clause" CV "all searchable attributes.

  My VO motion is:

  Select the username, name, RegisteringDate

  I would like to create my VC in a way that is the result "query with table Panel:

  UserId | ___ |

  Name | ___ |

  RegisteringDate of | ___ | to |_________|

  For each search field, I set a variable binding (PName, PUserId, PRegisteringDateTo, PRegisteringDateFrom).

  Each field must be used in the "query with table Panel" only if it is filled with a value.

  You kindly help me?

  Thank you very much

  F.

  The criteria to view all searchable attributes is implied all the attributes of a vo. Each attribute is used unless you specify a value for it. The problem with this IS, is that you can not change it.

  However, you can build your own RESUME that works in the same way, but allows you to change certain attributes. To do this, you create a new business card and add each attribute, select the operation you want to test the attribute against (equals, start by,...). You do not bind variables for attributes specify. The framework will add them for you automatically.

  The only thing that can not this vc is check varies as you want to do when you check "RegisteringDate." To do this you must use bind variables.

  Once you have create this EGG and it makes you drag onto the page you can use it as the "all attributes searchable.

  Suppose we have the selection list with the name P1_DEPT and query for report

  select * from emp where deptno = :P1_DEPT
  

  We create dynamic Action on the evolution of the P1_DEPT point. We will need two real actions:

  1-> set value action

  Set the Type - > body of the PL/SQL function

  Published by: user10941925 on March 4, 2012 22:31

  Hello

  CASE expressions return a single value, for example a VARCHAR2. They do refer to code fragments.

  You usually don't need (or want) an expression BOX in a WHERE clause, or any other condition. I think that you were trying to do the equivalent of:

  AND     (     (:KAPCO = 'KAPCO'          AND cla.CLASS_NAME       LIKE '%KAPCO%')     -- Don't you want UPPER on this line?
       OR     (:KAPCO = 'NON_KAPCO'           AND UPPER(cla.CLASS_NAME) NOT LIKE '%KAPCO%')
       OR     (NVL (:KAPCO, 'ALL') = 'ALL'       AND cla.CLASS_NAME IS NOT NULL)
       )
  

  If you would care to post some sample data (CREATE TABLE and INSERT statements) and the results desired from this data, I was able to test this.

• How to create a procedure for REF CURSOR output with any WHERE clause?

  I have a requirement like this: I have a huge question that need to reuse in my code over 10 times. This SQL has about 50 lines. Here for these 10 odd times sometimes changes in WHERE clause (columns are the same). So I can't create a view as SQL is not static.
  
  I thought to write a procedure with a para of WHERE_CLAUSE entry. I pulled out a refcursor sys by adding where clause. But I can't do it because you cannot add a clause like this where clause.
  
  i.e.

  PROCEDURE dynamyic_query (p_where_clause IN VARCHAR2, p_out_query OUT SYS_REFCURSOR ) IS
  BEGIN
  
    OPEN p_out_query FOR SELECT ......... FROM table WHERE || ' ' || p_where_clause;
  
  END;

  The foregoing gives an error.
  
  How to handle such a situation? Any help would be greatly appreciated.
