Preserve Bind values in the SQL worksheet

Hello

When you run the SQL statements with var/binding settings, SQLD can persist values entered the tool reboots?

Is there a preference that controls this?

Java (TM) Platform1.7.0_71
Oracle IDE4.0.3.16.84
Support for versioning4.0.3.16.84

Thank you

Manish

Never mind. Found, he looked at me, but I was blind.

Under the worksheet, check 'Save the Bind Variables on the disc to the output'.

  • How to perform the procedure in the SQL worksheet?

    Hi, anyone knows, how I can execute procedure here?

    I try to EXEC sec_roles, EXEC security_admin.sec_roles, EXECUTE - there's a SQL statement error. When I use the CALL - there is no such procedure (I have execute privileges).

    Although in SQLPlus EXEC works, but there are problems with the standard SQL commands (each of them '2' returns any content is).

    Any ideas?

    Concerning
    Krzysztof

    EXEC procedure (parameters) is a plu sql (and some others) shortcut for

    BEGIN
   procedure(parameters);
END;

    So try that and then pressing / on anything in the sql worksheet that makes a statement in execution.

    Note that if your procedure has defined parameters as OUT or IN OUT, you need to provide a variable to accept the returned values.

  • problem with bind variables in the SQL query view object

    Hi all

    I use JDev 11.1.2.4.0.

    I have a problem with bind variables in the SQL query view object.

    This is my original SQL

    SELECT sum(t.TIME) , t.legertype_id
FROM LEDGER t
WHERE t.nctuser_id = '20022' 
      AND to_char(t.insertdate,'YYYYMMDD') in ('20130930','20130929')
group by t.legertype_id

    In my view .xml object query tab, I am writing this

    SELECT sum(t.TIME) , t.legertype_id
FROM LEDGER t
WHERE   t.nctuser_id = '20022'
    AND to_char(t.insertdate,'YYYYMMDD') in :dddd
group by t.legertype_id

    Davis here is a variable of Type liaison: String, updatable and necessary.

    I try to deal with Davis as ('20130930 ', ' 20130929') hoping the view object, run as my original SQL.

    But failed. The view object retrieves 0 line after that I run.

    Why?

    Thank you! ('2original SQL0130930', '20130929') ('20130930 ', ' 20130929')

    A variable binding cannot be used as this is why you must use years table. Check decompilation binary ADF: using oracle.jbo.domain.Array with ViewCriteria to see a solution.

  • How to get line numbers to display on the SQL worksheet?

    Dear Forum,

    I learn the SQL Developer.  I use it in my work and school.  At school, when I enter a query in the SQL worksheet, line numbers show in a column to the left of the editing area.  In my work, no line number.  I'm working on a fairly long query at my work, and the line numbers would be useful.

    I looked at tools / preferences / settings for the Code Editor, but do not find a setting for line numbers.  I looked at the other tabs in preferences and found nothing that looked useful.

    I have looked at all of the choices on the display list, but can't find anything on line numbers.

    Am I missing something obvious?  Line numbers is also available?  If so, how?

    I looked at various hits "line number" in this forum, but I've not found anything exactly the point.

  • Formatting characters in the SQL worksheet in the version 2.1.1.64

    Hello

    Using the version 2.1.1.64

    When I type SQL in the SQL worksheet calculation is to show formatting characters - for example all the spaces display as a light gray and a newline character appears at the end of each line.

    Formatting characters displayed not initially when I started to use this version. I don't know how this setting is enabled, but there doesn't seem to be a preferences setting to turn it off. Any ideas?

    Tools-> preferences-> Code Editor-> display-> Show characters

    should take care of your problem.

  • How can I turn off automatic formatting while working in the SQL worksheet?

    Friends,

    Hope you can help with a quick question.

    Is it possible to stop the automatic formatting of SQL statements in the SQL worksheet?

    for example, when I type select * double it auto SELECT formats becomes * FROM DUAL when I press return.

    I use SQL Developer 2.1.1.64

  • SQL Dev 1.5.3: No "feedback" in the SQL worksheet? for example "1,000 rows deleted.

    In SQL Developer 1.5.3 seems no "feedback" in the SQL worksheet when you insert, update, and delete records. So I like the timer, it is more important for users to get comments for the UPDATE and DELETE statements; for example, it is essential to know if 0, 1 or 1,000 files have been updated by a particular SQL statement - also for DELETE queries (for example when users forget the WHERE clause, feedback is an important mechanism to realize the error).

    Is it possible to turn on your comments? ("set feedback we" seems not be honored). What is this fixed point 1.5.4? Should be presented as a feature request?

    Thank you.

  • Passing the value of the SQL query select list

    Hello

    In my application users have in their homepage to a region which has two simple things, a part of LIST SLECT lov function and a BUTTON

    There is also another page which has a normal life to report which shows the employees.


    Homepage the user can select certain number of Department in its 'SLECT-LIST' and click 'open '.


    For example: If the user has selected a DEP_NUM_5 and click on the BUTTON it will be redirected to the page of a report and gets only showed the employees belonging to the Department 5.


    The report page contains a simple SQL query, and I understand that somehow I must pass the value in the SELECT LIST, where I now have the '?


    How can I do this, where should I start?

    Of course I would really appreciate an example of code, if anyone has time to do a.

    
select "EMP_ID", 
"EMP_FORNAME",
"EMP_SURNAME",
"DEP_NUMBER"
from EMP E
where E.DEP_NUMBER = ????????

    Hi Sozua,

    1. create an item hidden on the page where you have the report.

    I say P2_DEPT_NO

    2 assign to that in your sql query

    select "EMP_ID",
    "EMP_FORNAME",
    "EMP_SURNAME",
    "DEP_NUMBER"
    from EMP E
    where E.DEP_NUMBER = :P2_DEPT_NO

    below the area source ther is also an option

    Elements of page to submit-> put this element in this.

    for example;

    Page to submit items: P2_DEPT_NO

    3. change your button

    Action: Redirecting to page of this application

    Page: 2 / / assuming that page 2 is the report page

    Place these items: P2_DEPT_NO

    with these values: & P1_SELECT_LIST.  assuming that selection list is on page 1

    Hope this helps you,

    Kind regards

    What is your question has to do with Sql Developer?

    Unless you can connect you must mark ANSWERED thread and repost it in Sql and Pl/Sql forum

    the Japan Government says:

    Hi Jeff

    I expect that it runs the import at least.

    Get this error now on line 66:

    EXCEPTION

    WHILE OTHERS THEN

    BEGIN

    IF ((errorvarchar = ' ERROR') AND (tryGetStatus = 1)) THEN

    EXCEPTION---> line 66

    WHILE OTHERS THEN

    NULL;

    END;

    When you repost you should post the EXACT code you use. The code you posted is NOT valid: you must also REMOVE the WHEN of OTHER or you can expect everyone to book you to INTENTIONALLY HIDE any exceptions that occur. Why do you NOT want to know if Oracle finds problems in your code? That makes NO sense at all.

    IF ((errorvarchar = ' ERROR') AND (tryGetStatus = 1)) THEN

    There is NO SPACE after the "and" what is garbage just as far as Oracle are concerned.

    Either you have posted an incorrect code or your code has syntax errors and will not compile or run anyway.

    I suggest that correct you your syntax errors before reposting in the Sql forum. If you have pain to find their delete ALL unnecessary code to reduce the problem to the example as SIMPLE as possible, until you find the code causing errors.

  • How can I leave echo in the sql worksheet developer sql?

    When I generate out of the script from a sql file that is loaded into the spreadsheet sqldeveloper, the statement appears in the output pane before the results of the query.
