What the data type of this variant? (in the following)

What's the datatype of the following variant (use probe and indicator):
value -> 1356.00
I want to tranfer it to numerical data. When I tranfer it using "variant to data" function (the datatype used is string or numerical), An error occured:
 ERROR 91 occured at Variant to Data. The data type is not compatible with the data type wired to the type input."
Thank you very much!

You can investigate any Variant by using the 'Variant Probe' for download from LAVA.
It will tell you what the actual contents of the Variant were.

  • Why does the date/time scale info vary with the timezone of the machine running the browser?

    I have a system monitoring application (Uptime) that displays graphs with time/date data. The times displayed on a given set of data vary depending on where the browser is located.
    For example the site is hosted on a server in the US running on EDT. I select data for a period say midnight to 6am EDT. If I display that on a Firefox client also running on EDT the timescale shows 00:00 to 06:00. If I display that same data on a browser on a desktop in London it shows a timescale of 05:00 to 11:00.

    There are two different issues going on for shaolex.
    1) Bug in iMovie 9.0.6+ which will add or substract your GMT time to the original time the video was shot.
    2) The way iPhones save the date and time to the file. iPhone video files have the date and time the video was FINISHED instead of when it STARTED. The right aproach to fix this is to import the video to iPhoto and then drag and drop the clip into a iMovie event, then right click the clip in the Event window, then click CHANGE DATE AND TIME, and substract the lenght of the video from the time shown.
    i.e.   The video is 00:45:00 long, iMovie shows it as taken at 10:45:00. Change it to 10:00:00
    Other phones do the same but most of them write the date and time correctly on the filename.
    Hope this helps

  • How to Change the data type of infoobject from NUMC to CHAR

    Hi Experts,
    I have created an infoobject with data type as NUMC, i used in DSO as a key figure and i have loaded data up to PSA.
    Now i want to change the data type of this Info Object from NUMC to CHAR.
    Can anyone suggest me the solution for this issue.
    Regards,

    Hi pavan/binu,
    I have not loaded data into DSO i just added IO in Key fields and i started editing this IO then im facing error like

    2.SID Table /BIC/SZCUSTOMER contains data: Characteristic ZCUSTOMER cannot be activated
    Im also unable to edit the P & S tables in SE14.
    NOTE:I have data only in PSA and when im trying to load data to DSO Im facing these issues.

  • ODI 10g Load table havfing XMLTYPE as one of the data type

    I'm trying load data from source to target(Both Oracle) same table. The table has XMLTYPE as one of the data type. I can load the data, if I exclude that one particular column.
    Is there any way to load the data from that XMLTYPE column as well? Please provide your input.
    Source and traget has the same table structure.
    Version: ODI 10G
    below is the sample table structure.
    CREATE TABLE APPLICATION

    JOBTYPE VARCHAR2(20 BYTE),
    USRID VARCHAR2(20 BYTE) NOT NULL,

    APPLSTATUS VARCHAR2(30 BYTE),
    APPLDATE DATE
    Thanks

    Hi Pankaj,
    Remember that 1 character is not equal to 1 byte anymore while numbers/hexadecimals are still.
    So, if you have structures that are a mixture of characters and integers/hexadecimals etc, you can not move data from structure to structure as easily as before.
    In code you mentioned:
    LOOP AT L_TAB INTO L_REC.
    APPEND L_REC TO LIST_TAB.
    ENDLOOP.
    Avoid moving directly from L_REC to LIST_TAB. You can try to define a work area (WA_TAB) for LIST_TAB and use a MOVE-CORRESPONDING from L_REC to the WA_TAB. Then append WA_TAB.
    If the field names from L_REC do not match the field names in LIST_TAB, you can manually move each field value to the correct field in the work area.
    Reward points if this solves your issue

  • Any idea what this errorr means? the data type of the reference does not match the data type of the variable

    I am using Veristand 2014, Scan Engine and EtherCat Custom Device.  I have not had this error before, but I was trying to deploy my System Definition File (run) to the Target (cRio 9024 with 6 modules) and it failed. It wouldn't even try to communicate with the target. I get the 'connection refused' error.  
    I created a new Veristand project
    I added the Scan Engine and EtherCat custom device.
    I changed the IP address and auto-detected my modules
    i noticed tat Veristand didn't find one of my modules that was there earlier. (this week)
     So, i went to NiMax to make sure software was installed and even reinstalled Scan Engine and Veristand just to make sure.
    Now, it finds the module, but when i go to deploy it getsto the last step of deploying the code to the target, and then it fails.
    Any thoughts?

    Can you deploy if you only have the two 9401 modules in the chassis (no other modules) and in the sysdef?  I meant to ask if you could attach your system definition file to the forum post so we can see it as well (sorry for the confusion).  
    Are you using any of the specialty configurations for the 9401 modules? (ex: counter, PWM, quadrature, etc)
    You will probably want to post this on the support page for the Scan Engine/EtherCAT Custom Device: https://decibel.ni.com/content/thread/8671  
    Custom devices aren't officially supported by NI, so technical questions and issues are handled on the above page.

  • What is the data type for the Data Dashboard XY Graph?

    Hey all,
    I am playing with the new Data Dashboard (!!) on my iPad 2 and am having trouble setting up the shared variables that host data to the XY Graph.
    On my PC, in my Project (inside of a variable library) I have set up shared variables for all of the other controls/indicators available in the app; They all work great. However, I have not been able to identify the data type that is for the XY Graph in Data Dashboard. Of course, inside LabVIEW, I use a cluster of 2 arrays; this is not an available data type that I can select while creating a new variable on the hosting side. I have even gone so far as to create a custom control from my XYGraph in LabVIEW and then creating the data type "From Custom Control..." with no success.
    What gives? Am I missing something obvious? Thanks for the help!!
    Tom
    Solved!
    Go to Solution.

    Great question, Aerogoob.
    The XY graph can be bound to a 1d array of "points", where each point is a cluster of two numerics (X and Y). To create a shared variable of this type, you can set the data type to "From Custom Control..." in the shared variable properties dialog. Of course, first you'll have to build the custom control of the correct type: array of cluster of two numerics.
    If any of that doesn't make sense, please post back and we can walk you through it in more detail.
    Also, just for completeness, the chart indicator can be bound to a scalar numeric or to an array of numerics. The graph indicator can only be bound to an array of numerics.

  • What's the data type when defining a KF to show an integer with a sign?

    We want show some days difference which should be an integer with either a positive or negative sign.  I used to design a KF with type of Number with "DEC - Counter or amount field with comma and sign" as the Data Type, but find it shows 25.000 if the day difference is 25 days.  We want to show it as 25 other than 25.000.  Then what type would we pick when defining the KF?  Use Integer as the type?  But we also want it to show the sign symbol.
    The type field is dimmed as long as the InfoObj. is activated that I have to remove this field.  I've delete all the data loaded in ODS, PSA and etc., and I have successfully remove this KF from InfoSource, but when I try to remove it from the ODS, always get the msg "Can't move/delete locked InfoObjects" even if the InfoObject is not locked (I've tried SM12 to delete all locked entries and also tried relog on, but not helpful).  If someone gives any idea, I would be very appreciated on how to remove this KF from ODS and also let me what type should I use when creating a new KF which only shows integer with a sign!
    Thanks

    hey Siggi,
    Now after I right click the ODS and select "Delete Data", the KF eventually gets removed from the ODS without any error, then I continue to delete this InfoObj. 
    However, when I run the InfoPackage to load data to the ODS, get a msg (see below in between two dashed lines):
    Syntax error in GP_ERR_RSDRO_UPDATE, row 1,210 (-> long text)
    Message no. RG102
    Diagnosis
    The data object "I_S_OLDDATA" does not have a component called "/BIC/Z_field".
    Where Z_field is the InfoObject we deleted.  With this error, that's even worse since that stops any data coming in!  How to get rid of this error that we can continue to load data?
    Thanks

  • The data type of the variant is not compatible with the data type wired to the type input.

    Hello all..
    Iam curently struggling with the following:
    On my main(top)_VI, I have a mix-signal graph which will output several or one signals depending on the user. I also have an inner subvi which has the analisys i want to give the the data before outputing it to the main(top) VI, which has the mix-signal graph control.
    Now, I created a reference from the mix-signal graph and Iam imputing this reference into the subVI (which inside has a property node type_control_mix-signal graph in which Iam connecting the refnum from the top VI to view the output data). The data consists of an array of clusters of 2 arrays of doubles each.
    -- let say I create the property node type control mix-signal graph and i choose value property; it lets me put the array of clusters of 2 arrays of doubles each without problems; Now the second I connect the refnum pointing to the mix-signal graph on the Main_VI it brakes the cables and only accepts one cluster of two arrays os doubles instead.
    --if on the other hand I connect the refnum to the property node type_control_mix-signal graph before connecting the imput it doesnt complain until I run the VI where it gives the error 91.
    I have also notices a (strict) parenthisis at the end of the property node sometimes. [what does this (strict) means?]
    FInally if instead of creating the refnum from the Main_VI, I create either a xy graph or a mix-signal praph it lets me connect the an array of clusters of 2 arrays of doubles each without any problem. The refnum connection seems to be the problematic factor, but  by the same tolken I dont know any other means of sending that data from the inner to the outter VI.
    I have the feeling Iam missing on one or more Labview fundamentals regarding refnums.
    Any help will be apreciated

    You almost found it on your own. The refnum needs to be 'strict', that means that the data type of the graph is set (2D dbl), otherwise it will use the default data type. To do this you create the refnum directly from the graph after you have wired the correct data type to the terminal. In this case the refnum wire will break if you change the data type of the graph.
    Independend of this issue, I suggest you not to use the value property on the graph but directly wire the data (e.g. the 2D double) to the SubVI. The property value is by far the slowest way to get data, and 2D arrays are really some amount of data.

  • What should be the data type for a field in ztable?

    i am desing a ztable , wht should be the datatype for a field if i want to enter values like -1.5 and -2.5 , negative values with decimals what should be the data type???

    declare as P type. TYPE P DECIMALS 1
    Type P data allows digits after the decimal point. The number of decimal places is generic, and is determined in the program. The value range of type P data depends on its size and the number of digits after the decimal point. The valid size can be any value from 1 to 16 bytes. Two decimal digits are packed into one byte, while the last byte contains one digit and the sign. Up to 14 digits are allowed after the decimal point. The initial value is zero. When working with type P data, it is a good idea to set the program attribute Fixed point arithmetic.Otherwise, type P numbers are treated as integers.
    You can use type P data for such values as distances, weights, amounts of money, and so on.

  • What data type I can use if the text is more then 4000 varchar?

    Dear all,
    What data type I can use if the text is more then 4000 varchar?
    Please advice,
    Amy

    You didn't specify if you are referring to tables or code.
    In tables the limit is varchar2(4000) so anything bigger will need to be stored in a CLOB (as already mentioned).
    In PL/SQL code you can defined varchar2 up to 32K so varchar2(32767).

  • How to retrieve the data type of a column of a table?

    Hi,
    I want to retrieve the data type of a column of a table. At the moment I am querying "OCI_ATTR_DATA_TYPE" attribute but it is returning SQLT_CHR for both varchar2 and nvarchar2 data type columns. I need to distinguish between these two data types columns separately. Is there any API through which I could get the exact data type of a column i.e. "nvarchar2"?
    Thanks in advance.
    Hashim

    Hi,
    This is the Oracle C++ Call Interface (OCCI) forum - I'm not sure if you are using OCCI or OCI (Oracle Call Interface - the C interface) since you reference "OCI_ATTR_DATA_TYPE" which is more of an OCI focus than OCCI.
    In any case, you might take a look at "OCI_ATTR_CHARSET_FORM" which takes the following values:
    #define SQLCS_IMPLICIT 1     /* for CHAR, VARCHAR2, CLOB w/o a specified set */
    #define SQLCS_NCHAR    2                  /* for NCHAR, NCHAR VARYING, NCLOB */So, if you have a datatype of SQLT_CHR and OCI_ATTR_CHARSET_FORM is SQLCS_IMPLICIT then you have a varchar2 if it is SQLCS_NCHAR then you have an nvarchar2.
    If you are using OCCI and not OCI then take a look at MetaData::ATTR_DATA_TYPE and MetaData::ATTR_CHARSET_FORM which expose OCI_ATTR_DATA_TYPE and OCI_ATTR_CHARSET_FORM respectively.
    Perhaps that will get you what you want.

  • Can I modify the data type of a dynamic parameter?

    I am using CR2008 against an Oracle 11 db and have a report with dynamic parameters.
    One of the report sources is a custom view that selects all of the possible 'pay ending dates' where one of the fields from this view is used as the source for the dynamic parameter.
    The view performs a TRUNC on the date field in an effort to eliminate the TIME component.
    The problem is that the parameter definintion defaults to DATE/TIME (vs. just DATE). I'm wondering if there is any way to modify the data type of the parameter to be DATE only.
    I've searched several forumns but have not found anything.
    One solution I can think of is to have the custom view format the date field as a VARCHAR (sans the time component) which I assume would force the dynamic parameter data type to string, and then have the report perform a todate function on the value when applying the criteria.
    Anyone else have an idea? Just seems like CR should allow the developer to specify the data type- especially b/w Date and Date/Time, rather than make an assumption.
    Thank you in advance-
    emaher

    emaher,
    Here's what you can do:
    Leave the existing date column as it is in the view...
    Just add another column to the view that casts the the date as a VarChar data type and formats the date as you would like it to be.
    So now you'll have 2 date columns in the view... 1 that's still a date and another that a character string.
    Now for your parameter, use the date version as the parameter value and the text version as the parameter description.
    Be sure to set the "Prompt with description only" is set to true.
    This way the user sees the LoV in the desired format but there's not need to wrangle it back into a date for data selection.
    HTH,
    Jason
