• How to select a record in one table to manipulate data in a database?

  Hello community,

  Using 32-bit Labview 2015.

  I created a user interface that runs a query and retrieves my table from a sql database.

  I want to be able to manage only one record at a time by selecting the record in my table and then manipulate the data according to the needs.

  Whenever the user runs a query, I want as the first record in the table to be selected / highlighted.

  I want an indicator that is currently active.

  Then a click of a button, to be able to scroll the actively selected record.

  Once I have the selected record, I want a way to write a query to edit or delete the record.

  Is attached a photo of my query to select all of my table and connect data in my table (results).

  Attached a photo of my painting showing the timeline of my sql database.

  What is the best way to go on a record selection in a table and the modification of data with a query?

  Any help would be greatly appreciated.

  Thank you

  I guess that's not a table, but multi-column listbox.

  Right click, select--> highlight whole line selection Mode

  The value of the multicolumn listbox is the row index - you can write a local variable to highlight the line, the event structure to handle the user clicking on, etc.

  If you enable the property editable ListBox cells, you can allow users to edit the items of the listbox.

  If you want to get the data in row, you hint REF table and work with the array of strings in row - convert it to cluster, etc..

  I don't know, what type of data, it is, how you structure the database looks like, I don't even know if you use the wrapper to work with the database, I can't write queries for you.

  Something like Update Tablica Set Serial = '5' where ID = '22';

• Filter or manipulate data from e-mail server before coming to the mail program

  How can I manipulate the data of the mail server until it gets pulled a software such as outlook e-mail.
  For example, I want to write data of e-mail on db before it gets pulled into the e-mail program.
  
  Is there a way to define the filter as the structures that work between the email server and the DB?
  
  Of course, you can write the code with cfpop get the header etc, but what happens if I want to record all e-mail data on the database, how can I do that to save a copy of the email that is pulled in the e-mail program, if I understand well once the message is off the server so I would not be able to synchronize the db with the new messages with a kind structure of the scheduled task.
  
  Or is it really something that you can configure completely by the parameters of the mail server itself? Here again, in shared or vps of installation, you probably haven't a lot of settings to set as you may not beside Server.
  
  Any ideas will be appreciated.
  
  Thank you.

  (a) use a DEDICATED e-mail account, which is NOT checked (= email
  Downloaded) from any e-mail application
  (b) use CFPOP to retrieve electronic messages, analyze needs, store data
  DB and delete the message
  (c) use intrusion via CFMAIL to send a copy of the message to another email address that
  Download messages for archiving (if necessary at all - you are
  already to store mails in the comics...)
  (d) [optionally] based on use of the e-mail headers, subject, body, etc intrusion via CFMAIL (or
  a gateway SMS or IM) to inform staff on new
  request/ticket/whatever

  just some thoughts...

• Data of heart rate watch/iphone for mac?

  I don't know how to use the on the watch heart rate monitor and I know how to see the daily lists of heart rate through the day on my iPhone, but I can't figure out how to get all the data that is listed on my MacBook Pro or even an app to see what traced on my iPhone 6.  The list is great, but I really want to see this trace on another way.  The apps I've seen for the iPhone can take each day and give me an average, but which is useless, since a few days I do intense exercise and others do not and average is not what I'm looking for.

  Thanks in advance for any help.

  Hello

  Health and fitness data from other sources, iPhone, and Apple Watch are shared with and grouped within the health on iPhone app.

  The data of frequency heart he include a chart, that trace data of heart rate of your choice of course day, week, month or year (press the tabs to change the time period):

  -In the health app (red heart on a white background), go to: health data > Vitals > heart rate.

  -To add the table to the health Dashboard app, enable this option.

  This and other application of health data can also be exported, which you may find useful for a more detailed analysis (health app: health data > All - Share at the top button on the right).

  There are also a few third-party applications that you might find useful - for example:

  Access to QS

• Manipulate the subdashboards with a loop for?

  Hi all

  Here is a picture of what I'm trying to do: basically, I want to choose the (3 x 3) A subarray, manipulate data, then

  Select the subarray B (2 x 2), manipulate data, and finally select the (4 x 4) C subarray and manipulate its correspondent

  data. In my real problem, I have more than A, B, C. I have a number any variables.

  I have a 1 d table, below, that I use to make a kind of mapping to my 2D table so I can choose the appropriate sub-table.

  Please see the VI attached and see if my approach is logical. To be concrete, the end result of my VI must be a 2D array containing

  A, B, C and for each variable, I want the sum total of all the numbers corresponding to this sub-table.

  For example, for A, I want 1 + 2 + 2 + 2 + 1 + 5. My real data manipulation would be more complicated, but if I can understand this simple case,.

  the real case will follow.

  I do not know where to store each subbarray in my loop and WHEN to do my manipulation of data, it must be inside of the inside of the loop, outdoors, where? See the attached VI.

  Thanks in advance.

  

  I think you need a boot and wiring through the case of fake.

  Note that the output is a table to a dimension.  Because pages can be of different sizes, the pages 'A' and 'B' contain empty elements. If no match is found fo a 1 d, a full page table element will be empty. To see this 'B' to replace in the table 1 d with "D".

  To make your number a string number followed by conversion table amount works well.

• Acceleration in the frequency domain

  Hello

  I enclose a vi that I already modified the existing example. I will use this vi to measure pressures (pressure sensor) and acceleration (from an IEPE accelerometer). Each of the two sensors is connected to a housed in a chassis CompactDAQ C Series module connector 4. The pressure sensor measures the pressure of the water flowing in a pipe while the accelerometer will simultaneously measure the vibration of this pipeline caused by the fluctuation of water pressure. In this vi, I am connecting a signal of pressure and acceleration TDMS file and then read the two signals on the cards of distinct waveform. The acceleration signal is written and read in the time domain. I need your help to make change more on this vi to take the acceleration signal and read on a separate table in the field frequency and written also the frequency of the field values in a file of PDM. After this change, the vi is supposed to have three graphics of waveform (pressure, acceleration time-domain and acceleration in the frequency domain and opens two tdms files, one for pressure and acceleration in the time domain and one for acceleration in frequency domain.)

  I tried many ways all failed because I'm not very familiar with the measurements of vibrations.

  I thank in advance.

  Hello

  It is important that you should decide if the frequency data you are interested in are constants based on time, or if you need to know how the data of frequency changes over time.

  For constant frequency over time, take a look at the Fast Fourier Transform: http://www.ni.com/white-paper/4541/en/

  If you need to know how the frequency display, take a look at the analysis of the frequency of the common time: http://www.ni.com/white-paper/3548/en/

• Decimate an array of meaningful size to 1 GB of data and apply the filter

  Hey guys,.

  So I used a high-precision laser Interferometer to collect data to frequencing 10 MHz, which will lead to a 1 GB of raw data files. I converted this position given to speed for parsing data. But I still have a file of 1 GB with billions of lines for treatment. I'm supposed to get all frequencies below 1500 Hz according to the results in the time domain analysis for lower frequencies. I have no idea on how to proceed on this. Any help is greatly appreciated.

  In addition, due to the size of the high line, Labview meets to errors of memory, that's why I want to decimate the 1 GB file into meaningful data.

  
  

• I use a simple low-pass, but the output of the filter outputs at a different frequency, even if the input frequency is the bandwidth

  I'm simulating a sine wave at approximately 1000 Hz (I'm variable according to the frequency with a slider), I would like to pass this signal by a lowpass filter (butterworth) with a high frequency of 2200 Hz cuttoff and a low pass to 2900 Hz frequency. However, the output after the filter frequency seems to be lower in the order of a thousand. the output frequency is about 0.1 Hz.

  

  Y at - it someone who can guide me please to solve this problem, I tried different filters and I'm still having this problem, it would be incorrect sampling?

  I enclose the block diagram and the front panel

  Because you use express screws and the type of dynamic data...

  You convert the signal of DDT (which contains the clock information) in a table DBL to perform filtering. Take it a DBL array (which contains no data of timing) and converted it into a DDT (which now contains no data timing). That's why when you try to view and analyze it you have lost all the data timing (frequency).

  If you were to exit table DBL of your filter and build a wave form and provide the dt to the waveform of the sampling frequency control, then it will work.

  Better yet, ditch the DDT and use waveforms from the beginning

  

• draw my sampled data

  Hello

  I am trying to trace my data sampled, but I think I'm doing wrong somethinng.

  I took 1000 samples pf my signal analog to 1Kz, dt = 10, stored in a table and through fft spectrum.vi I tried to plot the data, the frequency of Ampliteude vs. The analog input is a magnetic field meter, I measure my pc for the test field.

  The problem that in my view is the scale of the frequency, my opinion is that the Summit should be 0.05 Hz 50 Hz and not

  I have attached snapshots of my program and my results. could you please check and tell me if I'm doing something wrong?

  Concerning

  Garbage in, garbage out!

  You lie to LabVIEW so its bad data donations as well.

  

  If you read the help for the timed loop, you will see the dt is the source of synchronization units... you are collecting data at 100 Hz.

  Next:

  "dt" for a waveform must be in seconds at 100 Hz the dt should be 0.01 NOT "10".

  Then read the help, mod your code and you should get the results much more resonable.

• FREQ of FFT data

  

  I am trying to extract the data of frequency of my FFT as I pull data from the scale, as a 1 d array, in order to write easily in an excel file.

  As shown, I can get the delta-freq value, and I could do a loop for which calculates the values with the value of dF, but I would very much rather just extract the entire table that I do with "grandeur."  Y at - it an option for this, or should I write the loop and calculate values?

  Build yourself a table of frequencies, like this:

  

  (Just realized the label of the indicator is time table - as I usually do this waveforms.)

  You can also pass the array of magnitude in the loop with an autoindexing of entry, while omitting the size of array primitive wired for the number of iterations.

  Edit - to answer your question, no, there's no other easy method I know.

• Concatenate the date and time that are stored in two different date columns

  ... If you need to take the party date to a date column and the time of anonther part, then you must first convert them to a string, concatenate them and convert them to date.

  You don't need to do this.  What you have described is a way to do it, but this isn't the only way.

  If d1 and d2 are the two DATEs, you can get year, month and day of d1 combined with hours, minutes, and seconds from d2 liike this:

  TRUNC (d1) and (d2 - TRUNC (d2))

  Nesting TO_DATE and TO_CHAR in Oracle, is almost never the best way to do anything.  Oracle provides many functions (for example, TRUNC) to manipulate dates, but also of DATE arithmetic.

• How to query these data as a tree structure

  Hi, how to write a query to manipulate data like tree structure report? The rules for the structure of the tree are: CORE is always a node root (level 1), level 2 is a location any is not have "/" exclude those beginning of slot with PWR. This tree structure can continue to level 3 and so on

  POSITION OF SLOT
  CORE
  F1
  FAN
  PWR/1
  1
  2
  1/0
  1/1
  1/2
  1/0/0
  1/0/1
  G1
  G4
  G4/0
  G4/1

  Output, * the order of level 2 is not necessary must begin with the F1, it can be any value of level 2

  CORE

  F1

  FAN

  PWR/1

  1

  1/0

  1/0/0

  1/0/1

  1/1

  1/2

  2

  Hello

  If you want to CONNECT BY queries, you need to know the parent of each element.  Here's a way to do it:

  WITH got_parent AS

  (

  SELECT slot_position

  CASE

  WHEN slot_position = 'CORE '.

  THEN NULL

  WHEN slot_position NOT LIKE "% / %".

  OR slot_position LIKE '% PWR '.

  THEN THE "HARD CORE".

  Of OTHER SUBSTR (slot_position

  1

  , INSTR (slot_position, ' / ', - 1)-1

  )

  END AS parent

  FROM table_x

  )

  SELECT LPAD (' ', 4 * (LEVEL - 1))

  || slot_position AS padded_slot_position

  OF got_parent

  START WITH parent IS NULL

  Parent = slot_position PRIOR CONNECTION

  ;

  If you would care to post CREATE TABLE and INSERT instructions for the sample data, and then I could test this.

  An alternative to CONNECT BY would generate a string similar to slot_position, but including all ancestors, such as:

  CORE

  CORE/1

  CORE/1/0

  CORE, 1, 0, 0

• SQL Loader issue - CSV with commas and quotes IN the data

  Hello, I have a dataset for a simple table of 2 columns like this:

  Column 1, "it is given for"Column 2", with commas and quotes."

  Data are delimited by commas and may be surrounded by double quotes.  In ADDITION, it may include commas and quotation marks in the data fields.  I CANNOT manipulate data before sending it to SQL Loader.

  I set my file of control like this:

  DOWNLOAD THE DATA

  REPLACE IN THE TEST TABLE

  Fields ended by ',' POSSIBLY BOX BY ' "' TRAILING NULLCOLS"

  In this case, there is no way she can tell who's a delimiter or pregnant and which is part of the data.  As far as I know, there is no way that you can load it into the appropriate columns.

• DATE and time STAMP

  All,
  
  I am convert some sql server scripts to the oracle scripts. I met several times the data type DATETIME has been used in sql server scripts.
  
  http://docs.Oracle.com/CD/E10405_01/doc/AppDev.120/e10379/ss_oracle_compared.htm
  
  In the link above, I stumbled upon DATETIME (sql server) is equal to the DATE / TIMESTAMP in Oracle (Oracle).
  
  Which is better to use between the DATE and time STAMP, performance wise. Please give me some suggestions.
  
  Thank you

  Hello
  Use the DATE where you have the choice.
  I don't know that the DATEs are more effective than the TIMSTAMPs (even if I have no solid evidence). In addition, DATEs require less storage space, and there are more features available to manipulate DATEs. (These functions usually work on the timestamps also, but they start by converting the TIMESTAMP of a DATE).
