• The external table, question of double data type

  Hello

  We are the migration of 11g CL8MSWIN1251 to 12 c UTF8.

  Now, we test the exteranl tables and that we've met the problem below.

  We have a binary file (little endian) with fields of type double.

  In 11g, it is very well analyzed, but in 12 c obtained ' ORA-29913: error in the execution of legend ODCIEXTTABLEFETCH"" "".

  In the Oracle docs, I found this paragraph, the last sentence of worries.

  The DOUBLE clause indicates that the field is the same format that the C language, data type DOUBLE on the platform where the access driver is running. Use of the DATA IS {BIG |} LITTLE ENDIAN clause} can cause data to byte - swap before it is stored. Such data may not be portable between certain platforms.

  Here is an example of a test that works on 11g, Oracle Enterprise linux 6.5. And get the error above 12 c 7.1 OEL

• create a view with the double data type

  I have Windows XP with 10g 10.2.0.1.0
  
  I need to create a view of the double and with the type of data, such as NUMBER (5.2), NUMBER or VARCHAR2 (20).
  such as:
  create see test (view_test varchar2 (20)) as (select view_test from double)
  
  
  Help, please. Thanks in advance.

  It seems a little strange, but you can do something like this with the CAST function:

  SQL> create view dual_view as
    2  select cast(null as number(5,2)) col1
    3        ,cast(null as date)    col2
    4        ,cast(null as varchar2(30)) col3
    5  from   dual;
  
  View created.
  
  SQL> desc dual_view
   Name                                      Null?    Type
   ----------------------------------------- -------- -------------------------
   COL1                                               NUMBER(5,2)

   COL3                                               VARCHAR2(30)
  

  I used the NULL values, but you can use the actual values if you wish.

• The data type double in CT that is converted to PDM

  Hi all
  In short, to be able to remove channels and groups of a PDM file, I convert the file to a tdm, delete channel or group storage using screws and the convert to PDM. The problem is when tdms is converted to tdm, double data types (64-bit) became simple types (32-bit). Original tdms file has double inside, but CT and resulting tdms files have singles.
  Attachment VI made things I mentioned above. After execution of the it, I open tdms - 1.tdms in Excel with importing tdm (v3.3.0.0) and data type is DT_DOUBLE. But in the files tdm.tdm and PDM - 2.tdms, data types are DT_FLOAT. So the question is, is there a way to prevent duplicate converted to singles?

  Note: I convert the files tdms tdm, screw that removes channels and storage groups do not work with the PDM format.
  p.s. I'm on LV2011.

  Hello

  This is a known bug, CAR 399895. We'll fix it in the future.

  In your LabVIEW, you can try to change the next VI.

• What is the minimum value for the data type double?

  ... a more academic question: what is the minimum value of the data type double? I thought 'double', it is the 8-byte IEEE standard and what I remember, it's + - 1.7E + - 308.  The more different number of 0 should be 1.797E - 308.

  This is why I was a little surprised when I looked at the data output of my calculation of CVI, where I found the numbers with exponents of E-319 or E-324 as the smallest value...

  But I'm sure there's an explanation :-)

  Thank you for sharing with me,

  Wolfgang

  The largest number is indeed the order of + 1.7E + 308; There are a smaller number of - 1.7E + 308. Note that this is in fact the most negative number, which is the smallest by some reckoning. For the small beach of the Exhibitor, things get a little more complicated. 1E-308 can be represented with complete accuracy and resolution, but if you're willing to lose a few bits of precision, you can go down even further. For example:

  Double x, y, z:

  x = 1E-300;

  y = 1E7;

  z = x / y;               Give 1.000000000000000E - 307

  y = 1E8;

  z = x / y;               Give 9.999999999999999E - 309

  y = 1E18;

  z = x / y;               Give 9.999987484955998E - 319

  y = 1E23;

  z = x / y;               Give 9.881312916824931E - 324

  So, as you can see, values less than 1E-308 are possible, but they become increasingly more inaccurate and should not be relied upon.

• How to auto-off rounded af:inputText liaison with the data type Double?

  Hello Experts,

  If a component af:inputText is bind with a field whose data type is Double I saw if I enter 12.0 in the text field, and then it changes automatically to 12. Another example: 12,010 turns into 12.01.

  My requirement is to maintain the value that it has been seized. But the validation client side of the field, that ADF provides by default, should be present. I mean that ADF throws the error message if I get 12a.01; as it is not a Double.

  How can I achieve this?

  Any pointer would be vary useful.

  JDeveloper version: 11.1.1.6.0
  

  No, what I mean is that if you keep the zeros on the right, the data type is not a Double.

  Once you save 12.010 and read it again, you will see zero residue. You would see only the zero if you or the other say the number still show for example 3 fraction digits or if you store the value as a string that will store the entry as is and use a regular expression validator to ensure that only valid numbers are entered.

  In the first case ever number has 3 digits of fraction for example 12-> 12.000 and 12.010-> 12.010

  In summary, you will need to decide which way to go. If the data type must be Double, then there is no zero leakage or you must use the minFractionDigits which will always use the zero leak until the number of spezified. If the does not like what you have to store strings.

• How to handle the data type DECIMAL MySQL converted to DOUBLE in OBIEE 10 gR 3?

  Hi all
  
  I have a problem in OBIEE 10g to I use the MySQL database as datasource direct to the server of the OBI and I have a column in a MySQL table which was designed as the DECIMAL data type (18.0).
  This column is used to measure a length, and values are included in seconds (without decimals), in the form as:
  "1200"
  in the MySQL database.
  
  After the import of the MySQL table associated with the repository of the OBI, the OBIEE converts the DECIMAL data type column to the DOUBLE PRECISION data type automatically.
  
  My goal is to reach the values in this form, certainly in the sense of the term (not at the time!):
  hh mm ss
  
  In order to accomplish, I tried to change the format of column with the ROUND function:
  ROUND (db.table.column / * 3600 * 2)
  
  The problem is that it doesn't work well if values can be divided with no rest for example
  original value: 7200
  new value (ROUND): 2
  
  In the case of my example:
  original value: 1200
  new value (ROUND): 0
  It's false, because 1200 seconds are not equal to 0 hours, I want to see two hours of _0.33333_ OR I much prefer more _0 hour 20 m_
  
  Anyone have any ideas?
  I tried to make a view of database and importing that type of CHAR data in the database, but is not the solution too, because if I filter BI app or try to make a SUM the BI would drop errors...
  
  Kind regards

  Thank you very much for your help!

  Buddhist salvation,

  It seems to me that you would be better to use "Linear Mapping" in the palette of ANALYSIS "Suitable curve", but you should be able to get your code works by passing the name of the channel in this second parameter instead of an empty string variable.  You would have noticed that if you had OPTION EXPLICIT the first line of your code - always a good idea.

• Simulink Inport/Outport data types

  I searched for a while and I am unable to find documentation about what types of data I need to use the inports, outport, settings and in my Simulink models.

  Is there some specific types of data that are, or are not supported?  How VeriStand to determine how to coerce data to send the model?  Also, I was under heard VeriStand uses doubles for everything but then I saw a post that says he uses of I64.

  Any clarification would be much appreciated.

  VeriStand 2013 SP1 (probably upgraded to 2016 in next year if it's relevant)

  MATLAB 2010 b and MATLAB 2012 b (currently)

  > Are there types of specific data that are, or are not supported?

  I don't remember there being any limitation of types beyond what is stated in the considerations help document.

  Considerations relating to the integration of The MathWorks, Inc. Simulink® software models (model Interface T...

  The big hiccup I remember wasn't mainly with types of configurations and data bus.

  IIRC, you can choose any numeric type desired in Simulink. The structure of the model interface that uses VeriStand will handle any type and convert it to double so that it can be consumed by the VeriStand engine.

  > How VeriStand to determine how to coerce data to send the model?

  I think the way it works is that when VeriStand interacts with the Simulink model, it gets a list and information (pointer, data type) of inports, remote villages and settings. Thus, it can capture data from the model (because it has the pointer), and it can cast its data type (because he knows the type) duplicate. If you look at the example model model interface on line 212 it might help to make things more clear on how this could work.

  C:\VeriStand\2016\ModelInterface\custom\examples\template.c

  Double USER_GetValueByDataType (void * ptr, int32_t subindex, int32_t type)
  
  {
  
  	switch (type)
  
  	{
  
  		case 0:
  
  		{
  
  			/ * double * /.
  
  			(double) return (((double *) ptr) [subindex]);
  
  		}
  
  		case 1:
  
  		{
  
  			/ * only * /.
  
  			(double) return (((float *) ptr) [subindex]);
  
  		}
  
    	}
  
  / * return NaN, ok for vxworks and pharlap * /.
  
  	uint32_t nan [2] = {0xFFFFFFFF, 0xFFFFFFFF};
  
  	return *(double*) nan;
  
  }

  I'm guessing that the full implementation of which uses VeriStand is much more complex, but I think that the idea is the same.

  > Also, I was under heard VeriStand uses doubles for everything but then I saw a post that says he uses of I64.

  VeriStand engine uses indeed of all double rooms.

  You happen to remember this post and you can share the link? I'd be curious to see where this is said and in what context.

• Added properties (Group and channel) are not a numeric data type.

  I use a use to add two groups and channel custom properties. The properties are text and digital, double and whole.

  When I create a request in the browser, I selects the custom using the drop-down list property, but has only the drop operator "=" or "<>". "" The property is displayed in the data portal is a number of float. I had this problem when I was adding properties custom by using a script. I then tried "Navigatorinstallation / my Index DataFinder/Reset/Reset", then repopulated my search box, using the use on my raw data files. At this point, all the properties of my have only the "=" or "<>" choice of operator in the query.

  It seems that my properties are digital in the data portal, but the the query string of the browser.

  Thanks in advance,

  Hi Bill,

  You don't have to delete the files.  Choose the NAVIGATOR menu "settings > My DataFinder > reset... '. "can clilck on the UPPER part of the two buttons, one called"reset the index.  Which will remove all records in database and re-index all of your data files.  If you one of these properties have already optimized, set their State not optimized before resetting the index, otherwise the optimized property data types will persist.

  If this does not help, then the problem could be in the use that you use.

• Problem of XML data type

  I am trying to unflatten data from an xml file but my entry type for the type on the unflatten my guess isn't valid, and I get error 1106.

  Is attached, the file xml and VI

  XML file is in text loading constraints

  Your cluster of data type does not match your XML file. Fixed VI (LV version 2013) is attached. However, the file you posted seems to be a single element, not the entire file, so I can't verify that it works.

  If you have a previous version of LabVIEW, the cluster lacked a time stamp and had a cluster at the end which should be a string.

• Cannot write the FFT of the integrated double data

  I am a beginner to Labview environment.
  I have acceleration Vs time dat file .lvm
  Can I get the double integration of this
  acceleration data for trip data.
  Can I get FFT of displacement and displayed on the graph.
  Up to this point VI works
  But now if I connect this FFT of moving to 'write the measurement file' then it displays error.
  Please help me... and correct the error...  All I want is two column data, frequency and

  the other of the amplitude of movement.
  I have attached all files
  I ask you to correct the VI please...
  Thanking you!

  The concepts that you'll want to research are"matrices", "indexing of tables", 'automatic indexing', 'cluster' and 'type of waveform data'.

  The loop IN the first VI I sent used the automatic indexation to take each element of a table 1 d of the clusters and perform operations on them separately to convert them to a waveform.  Exit tunnel also uses automatic indexing so that the end result is a table 1 d of waveforms.  I used the loop, so that no matter how many items appear in the table, you get a corresponding number of signals to the "writing on a file of measures."

  In this case, because the output of the FRF is a single cluster (and not an array of clusters), the loop FOR was not necessary.  The VI attached this time takes the output of cluster of FRF and maps the cluster to a single components build the wave function and you get a result of unique waveform.

  I have no sound and Vibe loaded on my computer at the moment, so I can't run your VI and see the result of the integration of the snout to the Cloaca VI.  The output data type is "Table 1 d of waveform" and your indicator and your two FRF can accept only waveforms.  I put a function between integration and the indicator/FRF array index, but if there is more than one waveform in the table, it would be the wrong solution.  My solution corrects the broken wires but throws waveforms 2,3,4... If they exist.

• How to convert an array of string elements to a cluster with elements named different data types?

  I'm looking for more help with the conversion of an array of elements of the chain in a cluster containing elements named different data types.

  I am importing data from an Excel worksheet.  He is coming in LabVIEW as separate (channels) 3 tables: 1) Variable name, (2) three possibilities Int, double, String) data type and the value 3), with the clues in each table corresponding to a separate variable (I have about 180 variables to import).  My ultimate goal is to convert the string array of 'Value' in a cluster.  But I want the correct data type in the cluster and I also the elements of the cluster name to match with the string 'Variable name' table so that I can use the Unbundle based on the name in my main VI.

  Please see attachment a Subvi for more details.  I did the size of the new items of tables 5 for simplicity.   I realize that labels property cannot be changed during execution and I don't think I need to do.  I just want to use the production cluster (mainly the unbundle by name) to help design my main VI.  I will need to 'read' and 'write for' the cluster during execution, but I won't need to change the names of the items.

  I was also wondering if there is a better way to import data from Excel?  Is it possible to import directly into a cluster immediately rather than put everything as strings?  I have attached a Subvi showing how I currently bring in data (found on the forum somewhere).  It comes as table 2D, which I divided into 3 separate tables that I mention above.

  I am open to any suggestion.  Thank you very much.

  -Mike

  Instead of trying to create a cluster, I think I would use only variant attributes.
