Analyze the data in the column

Hello, sorry if this has been addressed before. What I have is a large CSV with 60 000 rows and 7 columns.

I wanted to make calculations of the file existing on the columns 3 and 4 I have done with tables index and formulas.

What I want now, is to put these 2 new columns 'calculation', in the same csv file from 1st row, all the way up to 60 k lines and after the existing 7th column, that is, columns 8 and 9, any ideas?

Thank you

You take the original 2D table read, the work is transferred, add the new data with the picture of the building and then convert the result of this. Rewrite the new 2D with writing table in the spreadsheet file.

Analyze the text and identify which columns contain unpaired data

Hello world

I want to write an elegant solution in LabWindows-CVI to accomplish the same thing as what I implemented in LabVIEW.

The client does not use or do not own LabVIEW. I have to code the solution in the CVI.

Order to simpify the explanation of what it is that I try to do, I wrote a small example in LabVIEW (see below):

The code needs to parse a string to determine which data column includes unpaired. To do this, I first removed the unwanted text on the top and bottom. I also removed the extra space between the 2 groups of data by replacing the two separated by one to facilitate the next step. The result string has been converted to a table 2D-string. Only the columns you want to search for remained (total of 16 columns). Table 2D has been transposed as the table 1 d of research searched each line, I want to look in each column. 2D table transposed in its entirety was sought of all no corresponding values, which fills a table 1 d of boolean. I converted the table 1 d of boolean to a number to see if data 'no match' has been found. If none have been found, the value would be zero.

I need help to encode this in CVI.

Thank you very much

Ray, aspect string makes me think that it's a memory dump, while I designed a solution that analyzes the values of the whole of the chain and operates on them, instead of working on the string itself. Take a look at the attached example which should be what you're looking for. feel free to add comments or ask for clarification on some instructions if you need.

Insert rows in based on the data in the column in the Table_A Table_B

Hello

I have a column (STRING) in the Table_A called specialization that is imported from an extenral application.

Data in this column is supplied as follows:

"Spec_A" - If the user wants to get Spec_A
"Spec_A | Spec_B '-if the user wants to get both Spec_A and Spec_B.
"Spec_D | Spec_F | Spec_W' if the user wants to get Spec_D, F, W, and so on.

So basically all the options are in the same column, separated by ' | '. I don't have an option to change this data will always come like that.
For each card, the user must meet certain criteria, so I need these data resulted in another table, in rows.

I'm looking a PL/SQL script which will analyze the string in the column of specialization and insert lines depending on the number of specialzations in Table_B with the user_name and Spec option.

So if the user name is Steve, and there in the column specialzations = ' Spec_A | Spec_B' I would like 2 lines insterted in Table_B, 1 for Steve Spec_A and the other for Steve with Spec_B.

Thanks for the help,
Diez

How to analyze the data of 10 bytes encoded in the HH306 of Omegatte data logger/thermometer?

I am trying to write a simple code for a HH306 of OMEGAETTE thermometer/travailleursduweb.com data recorder.

That is the problem. I communicate with the device via RS - 232, using Labview 8.5.1 and windows xp. I ask her for "all the coded data", which is actually the only option. He returns 10 bytes of encoded data, the manual describes the meaning of each byte and I understand that. The problem is that I can't analyze the information for use in labview, for example: I want to extract the temperature and simply display it.

on request, I get: 10bytes (read as a string from the serial port read buffer): display HEX: 02 00 A8 48 FF EF B6 49 B6 03 is perfect, and what I expect. Display codes: \02\00\A8\B6H\FF\EF\B6I\03 The Normal display is a series of special characters, I don't understand, especially since I don't think they are ascii characters that must match returned hexadecimal numbers! For the life of me, I can't understand how to extract the information (what are the 48 6 hexadecimal display) of what is returned. All string manipulation functions seem to work only on what is given in Normal view. (The 4th and 5th byte of the data are the codes of the BCD for temperature: for example the temperature was 64.8 degrees farenheight when I took this reading).

Can someone help me to analyze the data returned by this device?

Ok... I think that I thought about it. I found this: http://digital.ni.com/public.nsf/websearch/77C8F61D36F5A23086256634005ACB38?OpenDocument.

I guess the normal display garbled is corresponding to each hexadecimal ascii characters. I'm just not used to seeing characters beyond the decimal number 127 ascii or hex 7F.

So, basically, to analyze the 10 bytes of data:

(1) break the string read from the serial port in the 10 ascii characters (using String subset vi)

(2) son of each output string in the left input of 10 separate Type vi Cast.

(3) wire a constant U8 in each terminal 'type' VI Type Cast.

cables of 4) the chain of each Cast of Type vi output to the input of a number hexadecimal string vi.

(5) concatenate or use as you wish as hexadecimal numbers (now in string format) which cause.

See you soon.

analyze the 2 bytes at a time series data

I am acquiring 8 bytes of serial data and I would like to analyze the data in 2 bytes of data, so that I find myself with 4 measures of different temperatures. I tried a lot of things that I found in the forum, but I can't make it work. I have attached the VI is using string function analysis, but I'm not very familiar with this function. My fault my serial data so that you can see the data that I get.

Thanks in advance for your help

How to analyze the data of the cDAQ and Signal Express, especially after analysis?

In the first series of tests of my instrument, it took longer than expected for the race. Thus, the data was saved in 6 days. The file is too large for export to Excel. At the beginning of the project, I was as ignorant as I could go ahead and add analysis and the scaling of measures. By the scaling, I mean my data of switching current dew points or whatever it is that I record.

How to evolve the data to read the output data as expected 4mA = point of dew of-20 C or 0 PSIG? Can I pre program this to be recognized for each event?

For real analysis I am doing – I would first analyze the data I recorded and choose different points to send to Excel to graph and analyze. Is this possible?

Secondly, I would like to know how to scale and analyze my data in the project without having to do this later analysis in the future?

I have a cDAQ-9172 with LabVIEW signal Express 3.0 that uses four modules - 9211 2 modules of thermocouple, my 4-20 1-9201 module +/-10V module and 1-9203.

Thank you for any assistance.

Select the lines with the maximum value for a date where another column is different from 0

Hello

I need to write a query on a table (called DEPRECIATION) that returns only the rows whose date maximum (PERENDDAT_0 column) for a specific record (identified by AASREF_0), and where the other column in the table called DPRBAS_0 is different from 0.

If DPRBAS_0 is equal to 0 in all the lines of a specific record, then return the line with date maximum (PERENDDAT_0 column).

To be clearer, I give the following example:

Suppose we have the following data in the table of DEPRECIATION:

AASREF_0	PERENDDAT_0	DPRBAS_0
I20110010743	31/12/2015	0
I20110010743	31/12/2014	0

I20140012238	31/12/2015	445
I20140012238	31/12/2014	0

The query must return only the following lines:

AASREF_0	PERENDDAT_0	DPRBAS_0
I20110010743	31/12/2015	0
I20110010856	31/12/2014	332

I think that you have not worked on adf 12.1.3. In adf 12.1.3 you don't have to explicitly create the association. When you create the EO to your table, Association xxxxFkAssoc, will be created by ADF12.1.3 for you automatically. Please try this and do not answer anything... You can also follow the links below.

Hello

java.sql.Dateis the DATE of SQL which means it stores years, months and days whilehour, minute, second and millisecond are ignored. Also sql.Date is not related to time zones.

java.sql.Timestampcorresponds to the SQL TIMESTAMP, which is the exact nanosecond (Note that util.Date only supported milliseconds!) with customizable precision.
