• Writing user defined function the same way as the oracle functions

  Hi guys,.
  
  In one of the interviews, I saw the guy asked me to write a function defined by the user who will be the column name and the list of all values.
  
  For example
  
  Name: employees table
  Column name: Employee_Name
  
  Employee_name
  Scott
  Ivgun
  Jack
  Shane
  
  The query must be in this marker
  
  SELECT col_agg (Employee_name) emp_name of employees;
  
  The output must be
  
  Emp_names
  Scott, ivgun, jack, shane
  
  Please let me know if this is possible
  
  
  Any suggestions will be much appreciated.
  
  Thank you

  You certainly could write what a user defined aggregate function if you wish...

  for example this function will consolidate channels in a CLOB...

    member function ODCIAggregateMerge(self in out clobagg_type, ctx2 in clobagg_type) return number
    );
  /
  create or replace type body clobagg_type is
    static function ODCIAggregateInitialize(sctx in out clobagg_type) return number is

      return ODCIConst.Success ;

  OK, it's more that a function it uses a type of object that connects in operation internal to the ODCI... but it does what you ask. :)

• When I print my paper to "user-defined" size in Thunderbird by default instead of "letter". Have to change manually, but does not.

  I use a printer Brother HL-6180DW and the paper size to default printer to 'letter' 8 1/2 x 11 on everything, except
  When you try to print an email from Thunderbird. If I manually change the paper size in Thunderbird to the letter, it maintains for that impression, then default to "user-defined" which is 3.0 x 5.0. How to make the default format letter? Thank you.

  I have answered hundreds of posts here every month. Most of the time I don't know who or what 5 seconds after I'm done.

  I did not add... I said to delete. You can remove all in printers and when you restart Thunderbird and try and print with the selected printer is the will add stuff if needed. So bite the bullet and simply delete away.

• Question of the user defined Type (UDT)

  Hello

  The attached file is NEITHER sample to call a VB6 vi.

  The following is declared in the declaration section:

  ' Global declarations
  Dim lvapp As LabVIEW.Application
  Dim vi LabVIEW.VirtualInstrument

  When I paste these statement in another project (that I'm working on), I get an error 'undefined user-defined type '.

  Can someone point out to me were in the sample, these type definitions are declared?

  Thank you

  PS the attachment is indeed xxx.rar and not xxx.zip.  I changed the name because .rar has not been accepted.  Please rename .rar

  Thank you

  I forgot to mark references to my project

• Use of user defined function in mathscript containing a structure

  Hi, I am a novice user of LabView MathScript module,

  I have the following problem when integrating my code MATLAB, LabView, for HMM: in my program, I tried to call a MATLAB called "mixgaussinit.m" user-defined function, it shows this error...

  "

  I just noticed that these files appear to be copyrighted. My first question is do you have author permissions to post them in a public forum? If this isn't the case, then you can remove them. That being said, I have reviewed the code and it seems easy enough to work around your problems (provided that you have the copyright permissions). How to bypass the problems is to replace the fields of the struct with variables. There is of course allows you to change some definitions of functions for input and output the necessary variables which I think was the best 5 variables. You will also need to redo the code that uses a table of error checking cell. In total, I estimated about 30 minutes of work. I would have given you work around these files had not been protected by copyright. So, unfortunately, you will need to implement the work around you.

• variables of user-defined data transfer

  Hello

  I use the etherCAT 9144 chassis and is only supported by this hardware FIFO range target. After a search, I realized that the only way to transfer data from FPGA to the host by using user-defined variables. But these variables do not support the notion of FIFO. So which is the best practice to transfer data after measures (provable 10 Hz measurement of 15 values) to host VI?

  Thank you

  As mentioned, the 9144 only supports the analytical engine.

  In regards to what you do, it really depends on the entire application. For example, what is the master? Are there other systems at issue here? Etc. It's a good read, in general, although it might not help this second right: http://www.ni.com/white-paper/14151/en/

  A high level, you need to decide what you need. If you have need for deterministic communication, low-latency over long distances from a RT controller, the 9144 is probably the right choice. If you need low latency + streaming over short distances to a RT controller, you should look into the RIO MXI chassis. If you need mainly not deterministic low speed (10 hz) data mixed with low flow continuous over long distances to a windows or host RT, then ethernet expansion rio (9146,7,8,9) is probably the right choice. If you need high speed continuous with low control latency over long distances to a windows or RT host, you need a full cRIO controller. Based on what you've posted so far, its uncertain is the right person.

  Lets say you're stuck with the 9144 for now. As you can easily hit 1 kHz scanning cycles, it should be perfectly possible to data 'stream' to 10 Hz. If you run the scan at 1 kHz engine, then you are 100 x oversampling. Where it gets complicated is this requirement of sync. By default, acquisition input/output is synchronized to the clock of the scan (and you can see when the clock of scan is set by a knot of e/s FPGA). However, you can take complete control of a module in the FPGA and read inputs and outputs at any time if you please. In other words, you can set up so when DIO0 goes high you immediately enjoy all the values of AI 15. You can then transfer these values HAVE switched to the host using the user-defined variables.

• 9144 with FPGA and SGL EtherCAT custom user-defined Variables?

  Hello

  I currently have a small instrument driver (rs485) running on a chassis of 9144. The output values are communicated to the master EtherCAT using FXP numbers. I would like to pass these FXP to SGL, since I've upgraded to SP1 2012 LV with FPGA now supports numbers of SGL.

  Is this possible? I tried several times to create the Variables defined by the user of SGL in the project, but the date type is gray.

  Greetings from Munich,

  Götz

  Unfortunately, SGL is not a data type supported for communication to and from a 9144. The types of data available for the I/O user-defined variables are:

  * Fixed point
  * Signed integers (Int8, Int16, Int32, Int64)
  * Integers (UInt8, UInt16, UInt32, UInt64)
  * 32 bit field
  * Boolean

• What are user defined variables (UDV)?

  I'm trying to debug an application in real time and have worked on known issues for LabVIEW Real-time 2011. There is a term called "user defined Variables (UDV)" that opens occationally document known issues with other documents. It seems that UDVs can be created under target FPGA but I am unable to find any useful information on them. I know only local, global, shared, single, variable IO process.

  Hi Lucie,.

  The /o Variables using the help documentation gives a pretty good explanation of what a user-defined variable is in the section "data i/o Variables for Custom FPGA of e/s". I hope that this documentation helps!

• How to set 'User defined' palette display IMAQ?

  When I select the "User defined" palette on the screen, it shows just the regular grayscale palette.  I want to replace that with the palette 'Rainbow' but slightly amended in the range.  How can I do this?

  Thank you!

  MK

  Wire a new array of RGBs 256 elements to the User Palette of your image window property.  You can use IMAQ GetPalette to retrieve the rainbow palette and change that.

  

• How to create a user-defined Service

  Hello

  The Microsoft article "How to create a User-Defined Service" is very explicit. I understood how to deploy a file .exe as a windows service. But my executable creates and writes a .txt file that I do not see that appear when I starts the service. I have to do something special?

  Thanks in advance, supertreta.

  I found the answer: she was on C:\WINDOWS\system32. Sorry for my precipitate question.

• How to get user defined Native Types is displayed

  I added a new user defined native Type using type Admin

  

  I saved, closed and then reopened the Data Modeler, but he does not appear in the Source Type drop-down list when I define a column in the relational model. I've defined the relational model to use 12 c as the Site of RDBMS. Am I missing a step in the installer?

  I use 4.1.3 on a Mac.

  Hello Kent,

  the native DB types never appear in the column definition. You need to create the new type of logical data and map it to the native type or change the mapping of logical type existing. The steps are confusing because it's like the problem or chicken (which is the first), you you will be defined first:

  (1) define the native type - save definitions - defined by the user of the native types had to be saved in order to be available for native types logic mapping

  (2) identify the type of logic - probably VARIANT in your case, define the mapping of native type logic

  (3) in native type definition define the mapping of native code to the logical type (it is mapped on the CLOB type on your photo - probably you will change it)

  (4) save the definitions
