If statement help needed

I am an Oracle DBA being thrown in the java world, and I'm having some trouble with an if statement. I need produce a tag that looks like this:

1 customer name
3 address line 1
4 address line 2
5, Zip City State
6 countries

It is possible that the lines 4 and 6 have all the data. So in this case, I don't want to print these lines.

My if statement is less. It works as long as there are data in 4. If 4 is null then I get no results at all. Any suggestions how to fix this code?

Thank you!

{
If (4! = null) {}
If (6! = null) {}
var text = '1,3,4,5,6' ;}
else if (6 is null) {}
var text = '1,3,4,5' ;}
ElseIf (6! = null) {}
var text = "1,3,5,6." }
else {}
var text = "1,3,5" ;}
}

Hi sharonkovac,

Since your outermost status is "if (4!" (= null)"all the logic is procesed only when 4 is different from null.
Code indentation can help to better understand the logic.

{if(6==null)}
if(4!=null) {text = '1,3,4,5' ;}
else {text = "1,3,5" ;}
}
if(4!=null) Else {text = '1,3,4,5,6' ;}
else {text = "1,3,5" ;}

Best reggards,

  • Dictionary stats help?

    DBA dear friends,

    In my 11.1.0.7 database, I have an ID of SQL which contributes about 100 reads physical Mil a day in the database, he ran 85 times in the 24 hour period.

    Here is the SQL - it accesses the SYSTEM tables and EM monitors query type, and is not a request part of the application-

    Dictionary collection stats help reduced the physical reads? Or any other point of view that what must be considered?

    Is it still worth to try tuning the query?  Please share your entries...

    SELECT 'AQ_Messages_in_Expired' t. *
    Of
    (select q. owner | | '.' | | q . name , v. expired
    de v$aq v, dba_queues q

    où v. QID = q. QID and q. owner not in ('SYS','SYSTEM','WMSYS') and q. QID not in (206397, 206398, 206325)) t

    I don't see a MERGE JOIN CARTESIAN, which is good.  I do not see a stage for fixed table and it MIGHT help generate fixed objects statistics:

    exec dbms_stats.gather_fixed_objects_stats (null)

    You can see if they have been already generated by querying the SYS. TAB_STATS$:

    Select count (*) in the sys.tab_stats$;

    If it is empty then stats fixed objects have not been met.  Stats of $ service must be collected by the work of database statistics 'standard '.  You can collect these stats and run the query again to see if the run time is improving.  You can also check when the last statistics, what are the sample sizes and how closely NUM_ROWS agrees with a count (*) current tables questioned.

  • Error driver Power State failure in my 64it win8 - help needed

    Hello

    A DMP was related to your video driver nvlddmkm.sys takes too long to respond.  In order to make sure you need run driver verifier

    Driver Verifier
    Using Driver Verifier is a dubious proposition. Most of the time it will crash and it will tell you what is the driver.

    But sometimes it will crash and will not tell you the driver.
    Sometimes it will crash until you can connect to Windows. If you can't mode without failure, then you will have to resort to editing the registry offline to disable driver verifier.
    I suggest that you first back up your data and make sure you have access to another computer so you can contact us in case of problems.
    Then do a system restore point (so you can restore the system using the functionality of Vista/Win7 Startup Repair).

    Here is the procedure:
    Click Start and type "auditor" (without the quotes) and press enter
    Select 'Create a custom settings (for code developers)' and click 'Next' (or Type "check/standard/all" (without the quotes) If you want to check each of them (this will slow down your computer))

    Choose "Select custom settings from a full list" and click "Next".
    Select the entire document except for "Low resource Simulation" to win 8 do not check concurrency stress test and the verification of the conformity of DDI, click "next".
    Select "Select driver names from a list", then click "next".
    Select all drivers that are NOT provided by Microsoft, and then click "Next".
    On the next page, select "Finish".
    Restart the system and wait as he crashed to blue screen.
    Continue to use your system normally and if you know what are the causes of the crash, do it several times. The objective here is to get the system crash because Driver Verifier is stressing out the drivers. If it is not planted for you, then let it run for at least 36 hours of continuous operation.
    If you are unable to Windows because it crashes too early, try safe mode.
    If you can't mode without fail, try to use the system from the installation DVD restore to bring the system back to the previous point of restoration that you created.

  • Protection of session state - Arguments must have Checksum - help needed

    Hello world

    I use apex 4.0 and that you have defined:

    Protection of session state = True
    Page = Arguments access protection must have the checksum
    Point of application protection = Cecksum required - Session level
    Page data entry point Protection = required Cecksum - Session level
    Page Display-Only item = Cecksum required - Session-level Protection

    On the pages that contain an interactive report, calls to other pages updated and or to delete a record from the pharmacokinetics of recording work OK.
    I put these as follows:
    In the Interactive report link-> Link attribute column = onclick = "new top. Ext.apex.PopupWindow ({url: this.href, title: 'Change collation details', width: 530, height: 500, listeners: {'success': gReport.search}}). show(); return false; »
    Target = this Application Page
    Page = 302Item = P302_IDCLASS
    Value = #IDCLASS #.
    Page Checksum = - default user.

    The problem is the button 'Create a new record' that is on the page of interactive report. I set the button as:
    The attributes button = onclick = "new top. Ext.apex.PopupWindow({url:'f?p=&APP_ID.:302:&APP_SESSION.::NO:302:::',_title:_'Create_New_Classification',_width:_530,_height:_500,_listeners:_{'success':_gReport.search}}).show (); return false; »
    Action when click = redirect to the Page of this Application
    Page = 302
    Clear Cache = 302

    When I click the button I get the following message:
    Session state protection violation: this can be caused by a manual change to a URL containing a checksum or using a link with a missing or incorrect checksum. If you don't know what caused this error, contact the administrator of the application for assistance.

    If I change the attributes of the button to be:
    OnClick = "new top. Ext.apex.PopupWindow({url:'f?p=&APP_ID.:302:&APP_SESSION.::NO:::',_title:_'Create_New_Classification',_width:_530,_height:_500,_listeners:_{'success':_gReport.search}}).show (); return false; »

    It works OK, bu page elements are not clear.

    Could somebody please explaing to me what I am doing wrong so I understand my mistake?

    Thank you

  • Help needed recovery for Equium A300D - 13 X

    Hi all

    Having experienced too many problems for the list with my satellite a 300 d 13 X, hardware and software, I decided to go ahead with a restore to the factory settings.

    My first step was to create 2 discs recovery DVDs, using the Toshiba Recovery Disk Creator.
    As far as I know, two recovery disks were created with success, insofar as the recovery disc creator has stated as such.

    Not knowing what step to take next, I started the laptop with the fist of the disc in the disc drive, two thinking recovery that it would reset the laptop to its factory settings, but it does not.

    Now, when I start the laptop, I get the following message;

    BOOTMGR is missing
    Press Ctrl + Alt + Delete to restart

    who restarts the laptop showing the above message again.

    By pressing F8 at start up does nothing.

    By pressing F12, multi boot selection, reveals a start with 3 options Menu;
    HDD1: TOSHIBA MK2046GSX-(S1)
    CD/DVD: MAST * ADVD-RAM UJ - 850 S-(PM)
    LAN: Marvell Yukon 88E8040T

    If I select the CD/DVD option, a black screen with the text;

    Windows is loading files

    is shown. I am guessing it is the correct path to recovery.
    However, after the screens following recovery about the language selection utility etc., a text filled with the dialog box

    X:\windows\systems32\cmd.exe

    Cross, but eventually reached a static state line:

    Copy of F:\06948XSP.swm to V:\HDDRecovery\SWImg 1/6

    without to successfully complete the recovery process.

    Any help to fix this would be greatly appreciated.
    Kind regards
    KeV.

    > As as far as I know, the two recovery disks have been successfully created, insofar as the recovery disc creator has stated as such.

    What to tell buddy you've done everything right.
    The recovery disk was created successfully (you saw a message saying this?).
    Boot from recovery disk should start the collection procedure and you must follow the installation on the screen.
    Usually, this should work.

    The error; BOOTMGR is missing says that boot manager on the HARD disk has been removed and it of not possible to boot from the HARD drive.
    You must boot from the CD you have done; by pressing F12 choose CD/DVD drive

    Try to format the HARD drive using another CD of Windows.
    In this case, you need to set SATA compatibility mode in the BIOS, then you could boot from the WinXP CD.

    After that try the recovery disk again

    This static route implies that there is another network (10.2.0/24) connected through the LAN. But there is no other reference to it and especially not for this translation. So I wonder how it works?

    IP route 10.2.0.0 255.255.255.0 192.168.20.2

    In this pair of static routes, the second route is a specific subnet more and would be included in the first and routes for the next of the same break. So I wonder why they are there are. There is not necessarily a problem, but is perhaps something that could be cleaned up.

    IP route 172.17.0.0 255.255.0.0 Tunnel20

    IP route 172.17.2.0 255.255.255.0 Tunnel20

    And these 2 static routes are similar. The second is a more precise indication and would be included in the first. And it is referred to the same next hop. So why have the other?

    IP route 172.18.0.0 255.255.0.0 Tunnel20

    IP route 172.18.0.0 Tunnel20 255.255.255.252

    Select count (1) in the scott.emp where job = 'ANALYST' and (empno =: empno or empno is null);

    You check "IS NULL" on EMPNO clolumn. You should check on the value passed: EMPNO. It should be

    select count(1) from scott.emp where job='ANALYST' and ( empno = :empno or :empno is null ) ;

    Hope that the: value of EMPLOYMENT is required...

  • Stuck with - update-help needed

    Hello everyone and thanks for reading!

    I have the following problem with the update statement. Tables and data in them are as follows:


    Table 1: XML_TRANSFER
    create table XML_TRANSFER as
select 111111 TAX_NR, 1 TYPE, 3000 PRIJ, 3000 POBOT from dual union all
select 222222 TAX_NR, 1 TYPE, 720.7 PRIJ, 350.70 POBOT from dual union all
select 333333 TAX_NR, 1 TYPE, 2600 PRIJ, 2100 POBOT from dual;
    Table 2: FIR_SET
    create table FIR_SET as
select 2011 LET, 7 KROG, 111111 TAX_NR, 10 STEV_FAK, 2000 VALUE_ODPR, 0 VALUE_POBOT from dual union all
select 2011 LET, 7 KROG, 111111 TAX_NR, 11 STEV_FAK, 400 VALUE_ODPR, 0 VALUE_POBOT  from dual union all
select 2011 LET, 7 KROG, 111111 TAX_NR, 12 STEV_FAK, 400 VALUE_ODPR, 0 VALUE_POBOT  from dual union all
select 2011 LET, 7 KROG, 111111 TAX_NR, 13 STEV_FAK, 200 VALUE_ODPR, 0 VALUE_POBOT  from dual union all
 
select 2011 LET, 7 KROG, 222222 TAX_NR, 1 STEV_FAK, 200 VALUE_ODPR, 0 VALUE_POBOT  from dual union all
select 2011 LET, 7 KROG, 222222 TAX_NR, 2 STEV_FAK, 20.7 VALUE_ODPR, 0 VALUE_POBOT  from dual union all
select 2011 LET, 7 KROG, 222222 TAX_NR, 3 STEV_FAK, 100 VALUE_ODPR, 0 VALUE_POBOT  from dual union all
select 2011 LET, 7 KROG, 222222 TAX_NR, 4 STEV_FAK, 400 VALUE_ODPR, 0 VALUE_POBOT  from dual union all
 
select 2011 LET, 7 KROG, 333333 TAX_NR, 81 STEV_FAK, 2600 VALUE_ODPR, 0 VALUE_POBOT  from dual;
    OK, the tables and data are now set to the logic of "update".

    Look at the data in the XML_TRANSFER table.

    1st row (with TAX_NR = 111111):

    UPDATE statement in this case should work as: the VALUE_ODPR must be the same as VALUE_POBOT in the FIR_SET table.

    This part, I managed to do with this SQL:
    PROCEDURE     xml_update is
BEGIN

update fir_set an
set an.value_pobot = an.value_odpr

where let = (select distinct max(let) from fir_set)
and krog = (select max(krog) from fir_set)
and
  (select sum(a.VALUE_ODPR)-b.POBOT 
 
  from fir_SET a, xml_transfer b
  WHERE a.tax_nr = b.tax_nr
  and an.tax_nr = a.tax_nr
  group by a.tax_nr,b.POBOT) = 0;
  
  commit;
  end;
    Resoult is like:
    LET                     KROG                  TAX_NR                 STEV_FAK                VALUE_ODPR            VALUE_POBOT                  
---------------------- ---------------------- ---------------------- ---------------------- ---------------------- ---------------------- 
2011                    7                      111111                 10                     2000                   2000  
2011                    7                      111111                 11                     400                    400
2011                    7                      111111                 12                     100                    100  
2011                    7                      111111                 13                     200                    200               
    OK the following example is a little more complicated and I can't understand it. I don't know how to explain it properly... I'll
    Post the resoult and try to explain it:
    LET                     KROG                  TAX_NR                 STEV_FAK                VALUE_ODPR            VALUE_POBOT                  
---------------------- ---------------------- ---------------------- ---------------------- ---------------------- ---------------------- 
2011                    7                      222222                 1                      200                    200  
2011                    7                      222222                 2                      20.7                   20.7
2011                    7                      222222                 3                      100                    100  
2011                    7                      222222                 4                      400                    30  
    So what we need to do, it's that we check is XML_TRANSFER. POBOT - VALUE_ODPR > 0, if it is, then we are updating VALUE_POBOT with VALUE_ODPR.
    In the next line check us again if the above statement is correct, and if we do the same thing. The process will continue as long as the statement
    will be correct.

    If the statement is no longer correct to do this operation: XML_TRANSFER. POBOT - SUM (VALUE_ODPR) (ON THE INSIDE OF THE SAME TAX_NR! Then group by tax_nr!)
    and last update row with resoult. In any case, we can get negative numbers.


    I really do help I explained my problem so that you can understand what I want to achieve. If you have any questions do not hesitate to ask.

    Thank you very much for your help!

    Best regards, Cain!

    Hello

    OK, I think I knew this time:

                        select
                            a.rowid row_id,
                            case
                            when b.pobot

                                     over (partition by a.tax_nr order by a.stev_fak) >=0
                            then value_odpr
                            else value_odpr
                                +   b.pobot
                                -   sum(a.value_odpr)
                                    over (partition by a.tax_nr order by a.stev_fak)
                            end as calc_VALUE_POBOT
                        from
                            fir_SET a,
                            xml_transfer b
                        WHERE a.tax_nr = b.tax_nr ) tmp
                where an.rowid = tmp.row_id
                )
where let = (select distinct max(let) from fir_set)
and krog = (select max(krog) from fir_set)  ;

    Is this ok for you?

    Kind regards

  • If/then JavaScript help needed

    Hello

    I'm trying to write a script for a PDF in Adobe Acrobat form, but I don't have much experience with JavaScript and I need help!

    Basically, I have five fields as follows:

    A1 = a checkbox

    B1 = a field with a numeric value in it

    C1 = one field with a numeric value in it

    D1 = a field with a numeric value in it

    E1 = a field where calculation of the sum.

    I want to write a script that will enter into the sum of the values of B1 + C1 + D1 E1 if a1 is checked yes.

    If it is not checked yes, then he enters the sum of the values of B1 + C1 + D1 value by 2 (and rounded down) divided in E1.

    Can anyone help?

    Thank you!

    This should do it like the custom for E1 calculation script:

    // Custom calculate script
(function () {

    // Get the field values, number fields as numbers
    var a1 = getField("A1").value;
    var b1 = +getField("B1").value;
    var c1 = +getField("C1").value;
    var d1 = +getField("D1").value;

    // Set this field (E1) value based on the state of the check box
    if (a1 === "Off") {
        event.value = b1 + c1 + d1;
    } else {
        event.value = b1 + c1 + Math.floor(d1 / 2);
    }

})();

  • Otherwise, if the statement help

    Well I'm well enough to the 'if' statement and the "else" statement as well. But what do I do if I need 2 conditions to be met before that nothing is done in my form. I'll do my best to explain what it is I'm doing.

    I want radio2 to change its value to 2 when radio1 has a value of 2. But radio1 runs a different calculation of numericfield1 then radio2 made in numericfield2.

    Basically what I do is to design a guide to estimate for a flooring company. (Working on the carpet now section) Problem is that the carpet is available in 2 different widths. large carpet 12 and 15 wide carpet. Most of my customers don't know what width of carpet they will choose when I am at home to measure for carpet. So I was preaching different estimates for each. But rather than filling an entire form for 15 carpet wide, I want simple selections as if or not move us furniture or pulling automatically out carpets to be filled in the section 15 of width of the estimate that I answer the questions in section 12 wide. But here's the catch. Some of my clients are 100% sure that they choose 12 wide carpet (or scale 15 incidentally). If I don't want the calculations made, unless a check box has been checked if it does not confuse my customers. Thanks for any help

    Sorry, now I see:

    this.rawValue = cost15wide.rawValue * qty15wide.rawValue;

    You must .rawValue when accessing the value of the objects.

    Hope that works,

    Niall
