What is the syntax to judge a binding value is null?

Hello

12.1.3 JDev is used.

I want to judge #{bindings. ReviewerA.inputValue} is null or not, what is the syntax? I use this to control the visibility of a tab, however no matter the value actually is zero or not, the tab will appear, I am currently using "#{bindings." ReviewerA.inputValue} is empty", it works very well, thank you

I want to judge #{bindings. ReviewerA.inputValue} is null or not, what is the syntax?

#{bindings. ReviewerA.inputValue == null} or #{bindings. ReviewerA.inputValue! = null}

I am currently using "#{bindings." ReviewerA.inputValue} is empty. "

As far as I KNOW, 'empty' syntax is: #{empty links. ReviewerA.inputValue}.

  • What is the syntax to create segments?

    Hello

    segment can be created manually as table space? If Yes, what is the syntax to create the segment?

    Concerning

    The create table statement has a storage clause that is part of the clause of physical attributes.

    These clauses to define options for the creation of segment/measure. If you do not specify the storage clause, then the tablespace-level settings are used.

    However, the create table statement lets you not create segments or extensions directly. New extensions are to be created initially (when the table is created) or later, when more space is needed for the table, usually after several insertions that filled the original measure.

    Also remember that SQL is a language of generation 4. But there is no need to go into details such as the management of use or storage. All that and managed by the RDBMS.

  • What is the syntax to add a form element to a Web App entry form?

    What is the syntax to add a form element to a Web App entry form?  (Web Apps > > Layout > > Edit Template)

    for example: If you need a form text element should look like this: < input type = "text" value = "{tag_some-name}" / >?

    Which would look like if assuming a {} tag_image-upload tag or a group of radio buttons to boolean a type of entry in 'file '?

    Confused seriously, but he could learn quickly w / a link or an example!

    TIA

    You can not simply add any random field here, it doesn't work like that. This form is based on the fields that the web application has. If you just go through and add the form of entry web application and it has all the fields you need to send an item of web application.

  • What is the syntax for displaying tree based on a correlated subquery

    I need to show an effective dated tree. The reference date for the tree will be selected by the user. To do this I use a subquery to correlated against the underlying table with the entry into force provided as a bind variable. The following statement returns I want:

    SELECT a.tree_id, a.tree_pid, a.tree_leaf_name
    OF cit_fin_organization one
    WHERE a.effective_date =
    * (SELECT MAX (a1.effective_date) *)
    Cit_fin_organization A1
    WHERE a1.tree_id = a.tree_id
    AND a1.effective_date < =: f164_point_of_view_date)


    Adding where clause at the APEX generated SQL for the tree:

    Select "TREE_ID" id,
    * "TREE_PID" pid, * "
    * 'TREE_LEAF_NAME name, *.
    *'f ? p = & APP_ID.:51: & SESSION. : NO::P51_TREE_ID :'|| "' Link TREE_ID" *
    null a1,
    null A2
    of ' #OWNER # '. " CIT_FIN_ORGANIZATION ".

    is simple, but I did not come with the syntax that will successfully pass the SQL with aliases to the parser. Without references alias the request with its correlated subquery does not return, of course, the correct results.

    Can someone show me the correct syntax or suggest another way to accomplish what I want to do?

    Hello

    I don't have the structure of the table that you have, but the following works on the EMP table:

    select a.empno id,
           a.mgr pid,
           a.ename || ' ' || TO_CHAR(HIREDATE,'DD/MM/YYYY') name,
           null link,
           null a1,
           null a2
    from EMP a
    where a.HIREDATE <= (SELECT MAX(b.HIREDATE)
    FROM EMP b WHERE a.empno = b.empno and b.HIREDATE <= TO_DATE(:P19_HIREDATE,'DD/MM/YYYY'))
    

    P19_HIREDATE is just a list of selection with all the HIREDATEs in the format DD/MM/YYYY. Of course, this isn't a thing of real but life shows you can use aliases and the elements of the page.

  • What is the syntax to call a procedure with named parameters?

    I should know this, but I can't seem to remember how to do it and did not find reference.

    If I have a procedure like this:

    CREATE or REPLACE myProc (inParam1 IN VARCHAR2, inParam2 in NUMBERS)...

    If I want to call this stored proc with a call control and the name of the parameters instead of having to go through position, how should I do that?

    That is to say, I know that I can do: call the myProc('somevalue'1)

    But I want to be able to do something like this: call myproc (inParam1: = "somevalue", inParam2: = 1)-which doesn't seem to work. Anyone know the syntax I'm looking for?

    Thank you!

    I don't know if you are referring to the call to the procedure according to the parameters.

    His

    Call MyProc (inParam1-online "somevalue", inParam2-online 1)

    call MyProc (inParam2-online 1, inParam1-online "somevalue")

    Hopefully it's that you make reference to.

  • binding values in Multiselect guest-urgent

    Hi guys,.
    I have a problem. I need to constrain the values in a guest of multiple selection based on the values of an another command prompt.
    Now the problem is, the multiple selection prompt is binding values, but when I search another value (which must have been limited) it appears.

    I tried using variable presentation in the SQL for the guest. But also, it does not work.

    Any help please...

    Kind regards
    Ronnie

    Do you use two different guests or a prompt with two selections of column inside. If it's a prompt then you cannot use pre. variable in the sql query. given that the variable will be set only after you press 'go '. create two guests. one with pre. variable. then use this variable in the second line. in your dashboard you must select a value from the first fast b4 using your multiple selection prompt.

  • What is the correct syntax to reference a page point (P23_ID, for example) in a process of PL/SQL page after submit?

    What is the correct syntax to reference a page point (P23_ID, for example) in a process of PL/SQL page after submit?

    TexasApexDeveloper wrote:

    Variable binding is preferred: P23_ID you can also use & P23_ID. (variable substitution notation).

    Bind variable and static text substitution references are not interchangeable. For example, static text substitution references cannot be used in allocation targets:

    :P23_ID  := 'foo';  -- valid
    &P23_ID. := 'bar'; -- syntax error (or something weird or sinister due to SQL injection)
    

    Substituting static text references should be avoided in SQL and PL/SQL code because of the risk of behavior topic SQL injection and / odd error because of values containing quotes, etc.
