• Comparison of column values for Char and numbers

  Hello
  
  I have a requirement to compare the columns of the two tables value as described below-
  
  Table - T1 (NAME VARCHAR2, VARCHAR2 VALUE)

  NAME    VALUE
  A       1
  B       ABC
  C       2
  D       XYZ

  Table - T2 (NAME VARCHAR2, VARCHAR2 VALUE)

  NAME    VALUE
  A       1
  B       ABCD
  C       4
  D       XYZ

  Column 'NAME' is unique in the two tables. The comparison must exact match for the values of character ("ABC" = "ABCD", "XYZ" = "XYZ"), but in the numerical values, there must be a comparison of the value (T1. VALUE < T2. (VALUE).
  
  For example, the output from the example table above should be-
  

  T1.NAME    T1.VALUE    T2.VALUE
  A          1           1
  C          2           4
  D          XYZ         XYZ

  Thank you for your time and please let me know if any necessary clarification.

• Comparison of two values Datetime, but only the part of everyone's schedule

  Hello. I have two Datetime objects on my form. Both are formatted and only display the HH:MIPM. I have a validation requirement where I have to check if: TimeA is higher (: TimeB - 30 minutes). What would be the best way to build an IF condition allows to assess both these Datetime variables and determines if the time portion to: TimeA is greater than the time portion of: TimeB - 30 minutes? The part 'date' Datetime value should not be taken into account in the comparison.
  
  Any help would be greatly appreciated.
  
  Published by: Buechler on April 13, 2010 10:43

  If you really want to ignore the date and to assess the time, I would like to convert it each date to CHAR formatted as time column and convert it back dated to essentially match the date part. You can then perform a calculation of standard date to get the time difference and check if the difference is more than 30 minutes. For example:

  DECLARE
     TIME_B  DATE := To_Date(To_Char(:DATA_BLOCK.TIME_B,'HH24:MI:SS'),'HH24:MI:SS');
     TIME_A  DATE := To_Date(To_Char(:DATA_BLOCK.TIME_A,'HH24:MI:SS'),'HH24:MI:SS');
  BEGIN
     IF ( ABS(TIME_B  - TIME_A) > .021 ) THEN
        /* If you divide 30/1440 you get the numeric equivilent of 30 minutes. (.021) */
        -- Differnece is greater than 30 minutes!
        -- Do Something Here....
     ELSE
        -- Difference is LESS than 30 minutes!
        -- Do Something here....
     END IF;
  END;
  

  I hope this helps.

• Comparison of the value

  Hi all
  
  I need to compare two table datas and get the descripencies. The main table is M_data that has 15 columns and another name in the Loaded_data table that has 21 columns. First, I took the names of similar columns between the two tables and LEFT on the M_data table join. While the two tables has a first column Code, in the main table, the values are as 80,83, 70.98, 88,90 etc. but the Loaded table includes values like 8083, 7093,8890. Where is it possible that we can compare the values such that convert values of (8083, 7093,8890) please advice.

  Maybe I'm missing something, but don't you divide just a side of 100 (or multiply the other side by 100)?

• How to avoid values double in Oracle forms

  Hi all
  
  I am new to Oracle forms, working on Oracle Applications: 12.1.2
  Here I have a receipt of Transactions form,
  in what I Lot_Number and the amount of columns.
  
  Purchased items must be stored in the batch number.
  If 100 quantities purchased then 100 quantities can be stored in the unique batch number
  
  That is to say

   Lot_Number         Qty
    001                100

  or 100 quantities can be stored in different lot numbers.
  That is to say

   Lot_Number         Qty
    001                50
    002                50(The qty may differ)

  but not like what follows.

   Lot_Number          Qty
    001                 50
    001                 50.

  For the second line, if they chose the same as first batch number batch number,
  The error message should be as 'Lot number duplicated, select different batch number or update the quantity full original online'.
  
  Can someone help me solve this problem.
  
  Thank you.

  The element of calculation must be the number data type.
  In the article, you will see that these elements are added and are not part of the table block elements.

• When the value to display in the time format double digital indicator... Changes in value.

  Hi all

  I can't display the values that I want. I have a value double say 320 sent to a digital indicator where I edited the properties of it to display in a time format that contains only minutes and seconds as Yes, 3:20 '. Unfortunately, it takes the value and change it to another value and display that. I don't know what is the issue. If anyone knows the solution... Please post!

  There is an image attatched!

  Thank you.

  I believe only then due to the fact that when I convert a timestamp value to double as 03:20, he gave me 320. So I thought that the reverse can be trying. Should I just enter the total amount of seconds and that will show the Minuteseconds I want?

  Thanks for the quick response.

• Table of double filled by DLL contains odd values

  Hello everyone

  I'm working on a DLL call which must resize and fill in an array of double named "values" (2nd to the last parameter). I defined the signature as follows:

  _declspec (dllexport) uint8_t readDoubleArray(uint8_t handle, LStrHandle lPath, int64_t startTime,        int64_t endTime, DblArrHdl *values, LongArrHdl *timebase);
  

  Where is DblArrHdl

     typedef struct {      int32_t dimSize;      double doubles[1];        } DblArr; typedef DblArr **DblArrHdl;
  

  In the call, I read copies of a database and resize the table double as follows:

       int size = doubleArray.size();
  
        if (NumericArrayResize(0x0A, 1, (UHandle*)values, size) != noErr) {           setLastError(MG_ERR_LABVIEW_ERROR, "Failed to allocate memory");          return FALSE;     }
  

  I set the size and copy the values:

  (**values)->dimSize = size;for (int i = 0; i < size; i++) { (**values)->doubles[i] = doubleArray[i];}
  

  When I use the DbgPrintF to validate values, it gives me a value of about 120000 is correct. However, when returned by labview table contains strange data, such as 5.38564E - 315. Here's impression on the array of 'values' once he was through the DLL:

  

  Here's how I wired it, ignore the grouping, it occurs in the array of values that comes out of the call to the DLL.

  

  I have no idea how this can be. I followed the examples on the site. I also tried the normal DSSetHandleSize, but it changed nothing. No idea what I was wrong?

  Thanks in advance,

  Vincent

  Hi again,

  Vincent, you have a problem with the alignment. Simply add #pragma pack (1) before the table:

  #pragma pack (1)
  typedef struct {}
  dimSize of Int32;
  float64 elt [1];
  } TD2.
  typedef TD2 * TD2Hdl;

  and everything should be OK.

  See the example as an attachment.

• Store the calculated values in a table

  I do a program that computes a value double whenever the user clicks an OK button. For this I use a while above the NO-SCOPE loop that generates a new signal of each cross and a while loop around the code that I use (it requires the use of a while loop). I wonder, how can I keep a value whenever it is calculated in a list or table so that the user can see all the values.

  
  

• Incompatibility of DataCount double/DateTime PDM

  When writing data signal to a TDMS file I always find myself with a different values double number of (Y) compared to the timestamp of DateTime number (x).

  What is strange, is that DataCount for channel gives a correct result. However, when opening the file for reading, there is always a gap between the number of X and the values of Y, by channel.

  I already reported a bug about the AutoSave property and damage the data when you use TdmsWaveformLayout.PairedTimeAndSampleChannels and WaveformTiming.CreateWithIrregularInterval (). Workaround was to explicitly call Save() when editing the PDM file, for example creating groups/channels or write the sample data. It seemed to work pretty well, and I have not seen since corrupted data. However, I now feel a loss of data instead.

  Just to be safe, I connect the value reported by DataCount before and after each write operation. In this example 80 samples are written each time. It looks OK:

  2010-08-09 11:07:02.254 [9] DEBUG SE. Epiq.Acqis.Storage.TdmsStorage - P0 [mmHg] # before (double/date-time): 23920/23920
  
  2010-08-09 11:07:02.262 [9] DEBUG SE. Epiq.Acqis.Storage.TdmsStorage - P0 [mmHg] # after (double/date-time): 24000/24000
  
  2010-08-09 11:07:02.269 [9] DEBUG SE. Epiq.Acqis.Storage.TdmsStorage - P5 [mmHg] # before (double/date-time): 4400/4400
  
  2010-08-09 11:07:02.269 [9] DEBUG SE. Epiq.Acqis.Storage.TdmsStorage - P5 [mmHg] # after (double/date-time): 4480/4480

  But when I open the file and try to read the data I get an error saying "the number of stamps of time on synchronization channel... is not equal to the number of data samples.". DataCount confirms this, and there is always a multiple of the number of samples prepared at the same time lacking, for example 80/160/240 /... samples.

  If I use the TDMS Reader demo app and click a synchronization channel I sometimes (!) get a different error: "specified argument was out of range of valid values. Parameter name: wholeSeconds. ». I don't know if this error is related. The timestamps, I am writing to you are what returns DateTime.UtcNow. Not surprising at all.

  I have create/open the TDMS file like this:

  ... = new TdmsFile (filename, new TdmsFileOptions (TdmsFileFormat.Version20, TdmsFileAccess.ReadWrite, true, TdmsByteOrder.Native));
  
  

  When I finished to write data, I call Dispose() Save(), Close(), (in that order).
    
  Examples of data are written to the file using AppenAnalogWaveform().

  channel. Parent.AppendAnalogWaveform (channel, TdmsUtilities.CreateAnalogWaveform (e.Data, e.Signal));
  
  

  The CreateAnalogWaveform method returns aAnalogWaveform:

  Result AnalogWaveform = AnalogWaveform. FromArray1D(data.) Samples);
  
  result. Timing = WaveformTiming.CreateWithIrregularInterval (data. Timing);
  
  result. ChannelName = signal. Alias;
  
  result. UnitDescription = signal. UnitOfMeasurement;
  
  

  The PDM is saved after every call to AppenAnalogWaveform.

  What's really funny is that the docs for TdmsFile.Dispose () says:

  Call Dispose when you are finished using the TdmsFile. The Dispose method closes the PDM file and makes it unusable . This method does not save the file. Call Open to reopen the PDM file.

  So has really let the unusable file (sic!), it's great that you have documented it. ;-)

  Thanks for the code MiF-

  With your code, I was able to reproduce the bug you saw.  It seems to be closely internally with the previous bug you reported on autosave corrupt your data in special circumstances.  The fix for both problems is in the next version of Measurement Studio, but can also be obtained now by installing the runtime LabVIEW 2010.

  Again, please excuse me for the inconvenience that these bugs have caused you-

• Will I lose data conversion to double precision single-precision float?

  Before you say Yes...

  I use a crio unit in scan mode interface. Which returns the mode of scanning values in floating point double precision. Apparently I'm supposed to be able to choose between double precision fixed-point ("not calibrated") and ("calibrated") floating point data, but this feature seems to be exclusive to the fpga interface and is not available with the scan engine. The two data types are 64 bits per value, when it comes to the size on disk, anyway is still basically the same.

  The system continuously records 13 channels of comma floating double-precision at 200 Hz. using the binary file write, I measured it is about 92 MB/hr on the disk. (more than 120 MB/hr with PDM and much more to write on the worksheet) In short, this 92 mb/hr rate is just too much data on the disk on this system.

  The modules that I record since, 9236 9237 and 9215 c-series modules, have 24-bit a/d converters or less. Does this mean that I have not need 64-bit to represent the number and accuracy even?

  Can I force/cast point values double-precision floating that I receive of the variables of e/s scan engine to the data type of a different, smaller, as a single-precision floating point and retain the same precision?

  Nickerbocker wrote:
  between noise and precision equipment, I doubt that it makes much difference.

  You can test it by looking at the difference between a DBL and converted to SGL DBL. But I support the Nickerbocker trick. I don't think it will make the difference

• fixed point like solution value deal selector?

  Hey all so I am very new to LabVIEW and I'm doing a simple program.

  Right now I have a digital control that control my analog voltage on my board sbRIO 9636 (from the assessment package). According to the tension, I want to display a message on the LCD. I know you cannot use values FXP as case selector values. Is there a way to get around this? I thought to be converted to a string, but I want to have a case where no voltage between 0-1 displays a message, then 1-2 displays another message and so on and so on until 10.

  The flare in the case selector is integrated and cannot be changed by the programmer.  You will need to make the external logic and create whole selectors you need.  One way to do this is to create an array of constant values where you want cases. Then make a comparison of the value of the variable. Research in the resulting for the first table of Boolean true. Form to come and Index the search goes to the switch case.

• make a graph in real time of 1 DBL value at a time, using a loop for

  I have a somewhat interesting programming task where I have the following situation: (I have attached a mac version of vi Labview 2013)

  -Using a patented (pre-made and uneditable) sub - vi, who receives a value of 0 or 1 as input and reads off a single measure, whenever he receives 1 while a value of 0 is necessary to 'reset' of the vi to rehearse a new measure.

  -I would like to run this sub - vi repeatedly in a loop For each value of "measure" are sent to a curve of waveform to give a direct value (real time) for the graphic to display.

  -As it is, I have a vi file that simulates action in a loop but built in a 1 d array to get exuent values sent a waveform curve.

  -I don't know how to make a real-time graph which receives 1 value double both.

  -In addition, I want only every 2nd value sent to the loop for, but I already have several ideas on how to do it.  First of all, I am concerned about the target in real time.

  Kyle Shiel

  A graphic, not a graphic, allows you to update a point at a time. It would be inside the loop for. update the chart or not, you can use a select statement or the structure of the case.

  These are pretty basic functions in LabVIEW. Please see the free tutorials.
