Select the code,

(case when code = 'Bank' and then 'A'

case when there are

end

end

on the other

  • ORA-01502 error in the case of a unique index unusable and dml in bulk

    Hi all.

    The BP is 11.2.0.3 on a linux machine.

    I did a unique index unusable and issued a dml on the table.
    Howerver, oracle gave me the error ORA-01502.

    In order to avoid the ORA-01502 error, should I drop the unique index and bulk make dml and rebuild the index?

    Or is there another solution without recreating the unique index?
    create table hoho.abcde as
    select level col1 from dual connect by level <=1000 
    
    10:09:55 HOHO@PD1MGD>create unique index hoho.abcde_dx1 on hoho.abcde (col1);
    
    Index created.

    *
    ERROR at line 1:
    ORA-01502: index 'HOHO.ABCDE_DX1' or partition of such index is in unusable state
    Thanks in advance.
    Best regards.
    Do I have to accept the unique index maintenance workload(undo generation/redo for undo generation)
    when doing bulk dml?
    

    I think so.

    The amount of data you load compared to existing data in the table?

    If say for example, you add 20%, and then to compare the retention of 20% adds data during the major part collect to create all of the index after insertion so
    you choose the drop/recreate the unique index

  • Enum (type def) - structure of the case called update error

    Hello

    1. One of my (type def) enums is not updated the names of structure cases. I found something that looks like a probable error in the case where the structure,
    2. I had created one of the constants in the enumeration before I did a typedef. Therefore, I made new constants since the typedef and replace the original ones. and still, the structure of the case is not being updated.

    How can I solve this?

    also, I have one state machine inside the other. Is this right way to program?

    Somewhere in your code, you have the wrong typedef, or don't replace a control by the typedef. Must not have replaced all. I don't know if there is an easy way to search for; You may need to go through anyway.

    This problem has been resolved by renaming current Martin of the Volume of work. The reason to get the "file not found" error in the case of Martin is because there is a folder inside the current workload that has the same name as the Volume itself (the name of the "system" folder. Please refer to the screenshot above).

    @cabolivar, can you please check if you have any folder in your root folder which has the same name as the name of current workload? If it's confusing, please post a screenshot as Martin. Try out us and solve it for you.

  • Case returns the error on the value of type (error-17308)

    Hello

    I have the following problem with TestStand: I use a sequence setting tension on an instrument. The first step in this sequence is to choose the instrument to define. It worked absolutely fine so far. Next, I added a tool to select (called 2602A here). Now, it always works for all instruments, but not for this one. I also tested the Select / Case regardless, he does the same. The error message indicates that the type of my value does not match the type expexted. Yet, the type, as defined in the parameters.instrument is good (see attached photo). I tried with/without reference: same behavior. I tried with/without check Type: same behavior.

    Maybe I can specify that my instrument works very well, I tested the list of instructions under the indendently step case, without any difficulty.

    Any idea? Thank you in advance.

    TestStand:

    Hello

    Looks like you do a comparison in the "select" for a string type as seen by the value, but the setting for the case is an assessment rather than a string of values to compare to and I can not make sense since he's looking for a game (chained a ternary operator) or returns - 1 - making in this case doesn't make no sense - do in the select to return whereby cases to go.

    The step case type is more than a 1:1 comparison, however, you have already demonstrated, the case itself may be an expression - you must ensure that the expression is returned exactly the correct type, so-1 is not valid, but would be "-1".

    Who is?

    So I tried to replicate this - if I send a pure (as in "2604" string) number when I'm looking for Parameters.Instrument == "2604 A '? '" 2604 A': Parameters.Instrument == "2604 B"? "" 2604B ':-1

    He then drops the default case.

    If I switch 2604 'B' which then activates OK.

    If I pass in "fred" which fails with the error since we were looking for - 1 because it is a number, it does not work.

    If I replace the case expression with:

    Parameters.Instrument == "2604 A '? '" 2604 A': Parameters.Instrument == "2604 B"? "" 2604-B ":"2604 A.

    While expression first only returns a string, so you'll get to the channel currently selected string comparison AND if I get A 2604 or 2604 B then I get a return value that corresponds to the string passed, or get a string that does not match, so the case is not the right one.

    So Don't pass return - 1 = return pass which is valid for this case, but do not match the incoming parameter.

    Thank you

  • USB CODE 10 ERROR, complete the automatic entry in case of problem, problem keep after reboot...

    USB CODE 10 ERROR, troubleshoot automated, everything is OK, resart problem comes back after a reboot...

    What is the USB (type, manufacturer, make and model)? What version of vista are you using? The problem occurs if you start in safe mode?

    The following applies in some cases (I don't know if it applies to you but I don "t know the appliance, has no validation of the ccmplete and the message in its entirety (Word for Word), and I don't know if that's what you tried - but here it is anyway):http://support.microsoft.com/kb/933442/.

    If this does not work, try a boot minimum http://support.microsoft.com/kb/929135.  If the problem goes away then it's just a matter of tracking down the culprit at the origin of the problem.   Follow the procedures described in the article.  Once found, remove, delete, disable or uninstall.  Once remember to put Vista in normal status, as described in the procedures. If the problem occurs in clean mode then just restore the system to normal and reboot - this solution will not work.

    I hope this helps.  If this isn't the case, then when you have identified the device and answer the other questions, I have more specific recommendations.

    Good luck!

  • System fan failed error after the Swap case

    Hi, I read a number of similar positions on this issue but has not managed to solve my particular problem and was hoping someone can provide additional guidance

    I recently moved my HP Pavilion Slimline S5280t with a Cooler Master case, everything is OK except that I now get a 'system fan failure, press F2 to continue "message every time I start the PC.

    I know for sure, it is caused by the rear 120mm fan that connects to pin 3 connector on the motherboard chassis fan (I tested it with the old 92mm fan and the error message disappeared).  So based on what I read on the forum, the simplest solution is to disable / adjust the configuration in the BIOS to monitor fan, unfortunately, this option is locked to my motherboard (IPIEL-LA3) model.  If at this point, I have 2 questions regarding what I can do next:

    1. I guess the fan sensor detects for the fan RPM so since this is a 120 mm fan, the speed of ROTATION is less than a 92 mm.  It does not reach some predefined threshold and that's why the error message I received.  So I can solve the problem by exchanging the 120mm fan which runs at a higher SPEED?

    2. I read that there is a hidden menu of BIOS with some of the HP PC, accessible by pressing F11 (or some other keys that do not appear in the original start menu), I have tried F11 and which has become a diagnostic tool, does anyone know if a hidden BIOS menu exists for my particular model? (PC model: S5280t, q8300 CPU, Mobo IPIEL-A3)

    In addition, I don't think that there is an update of the BIOS for my model either... so I'm really out of options here.  Please help if anyone has any suggestions.

    Thank you!

    HW7777, welcome to the forum.

    After consultation on your problem with Erico, another Member of the forum, here's what I was told:

    "The three-pin connector for the fan has + (power), mass (-) and an analog tachometer signal." Given that you have tested the old fan on the system fan header and the error message disappeared, you have checked that the fan is indeed the question. You should try another fan to see if it did not have the rear case fan which is connected to the Sys_Fan?  If produce the same results, then you have reason on the down low, the origin of the problem.   If you want to keep the motherboard in the case of Coolermaster then you should consider making or buying an adapter to mount it in her 92 mm fan. Since the Coolermaster case is much larger, you should be able to mount the fan somewhere. There is a lot more air in the Coolermaster case compared to the business slimline the mobo was originally in. "You are right that there is no update available BIOS.

    (2) record by using the same query (either design or using CREATE_GROUP_FROM_QUERY) group to create and loop through the record group.

  • structure of the event within the structure of the case? error or limitation of LabVIEW?

    Hello

    I am trying to reach a structure of the event within a box structure. The event is triggered by a mouse event (mouse down, move to the top).

    This vi tries to simulate behaviour of the device with a sensor, so the mouse triggered the structure of the event, won't be there in real working environment, so I can't remove the structure of the case.

    But as I noticed that if I try to click on the drawing (that my mouse events are triggered with) before activating the Boolean condition of 2D, I can access is no longer the component front (button, leads, etc.).

    They seems to be frozen. But if the case is true before you try click on the 2D drawing area, everything seems to work well.

    Is - this protected by a kind of LabVIEW bug or there is a limitation?

    These are my screws.

    I'm still working on the resumption of this problem that AxshunJaxun has been able to help me to diagnose properly.
