• Calling stored procedures with parameters with the database connectivity Toolkit

  Hi all

  I'm new to the forum and struggling to find a solution to a particular problem I have in this respect, using the LabVIEW Database Connectivity Toolkit on a project, I am currently working on my work.  I have a database in which I tables and stored procedures with parameters.  Some of these stored procedures have input, output and return parameters.

  I tried to follow this example, but to no avail: http://digital.ni.com/public.nsf/allkb/07FD130746083E0686257300006326C4?OpenDocument

  Such a stored procedure I am working on the implementation is named "dbo.getAllowablePNs", running "SELECT * from DeviceType" (DeviceType is the table).  In this case, it requires no input parameter, it has an output parameter that generates the table [cluster] and has a return parameter that returns an integer value (status code for execution) to show if an error occurred.  The DeviceType table has 3 columns; ID (PK, int not null), PN (nvarchar ((15), null) and NumMACAddresses (int, null).)  I have surpassed many examples and I talk to the support OR try to implement this and similar procedures stored in LabVIEW but have not been successful.  I am able to connect to the database with the VI of open connection without error, but spin in some confusion as a result of this step.  I then try to use the VI of parameter query create to call the stored procedure and set the parameters.  I guess I would then use the Set parameter value for each parameter that is connected to the entry of parameters on the previous query with parameters VI VI?  I am also having some confusion during and after these steps as well.  I would greatly appreciate advice or suggestions that anyone could have in this situation because I am not a SQL expert.  Also, I would be happy to provide more information that might be useful.

  Kind regards

  Here's what I use to do this.  I think I had to change him create parameterized query VI for him to work.  There is a post on the forum about this somewhere.

  

• Database Connectivity Toolkit (insert multi line)

  Hi all. I recently got the toolkit of connectivity (DBCT) database on LabVIEW 2016 and I try to insert several rows in a database.

  Using a sine signal input I tried to insert 50 rows in an iteration, but each method I tried returned 50 values in a line. The end of the constant of the line and table using chain worksheet, returned what looked like 50 lines, but when I questioned "SELECT COUNT (*) FROM... "the number of rows equals the number of iterations.

  On another post on the forum, someone suggested that it is not possible to insert several lines using the DBCT. Can anyone confirm this?

  I wrote a code that allows me to insert 3 rows in an iteration, under a single connection. However, this method is very time consuming and would not work for large amounts of data.

  

  Can anyone think of a better way to do it?

  Thanks in advance,

  Lisa

  Create your own query, and use the query execute VI.

  

• database conectivity

  Hello

  I am new to SQL server and Toolkit for labview data base connectivity. I made a program to write the data in the SQL table but I get the error message "ADO error: 0x00000001.
  Error argument; the number of columns is not equal the number of parameters. ». I have attached the error message. Please help me out here.

  Kind regards

  In fact, this problem is a case perfect for why the CSD is a very bad choice. The problem is that the error message is not clear at all. The problem is that you turn your input strings in a Variant array, but the result is a variant that contains an array of strings. What entry wants - but doesn't tell you - is that he needs a table of variant where each element is a variant with a string in it.

  Much better to use a simple interface that allows you to enter SQL directly. Then when you get an error, you can be sure that the error is actually tell you what the problem is. Check here for a more comprehensive analysis of the subject and some drivers causing problems.

• Adding data to access DB with connectivity toolkit?

  I'm trying a new way to add data access instead of AciveX due to not knowing the commands necessary to interact with him.  Instead, I try to use the database connectivity toolkit and learn new techniques.  It is also an introduction to the variants that can ask me that question.

  Problem: Try to add data to multiple columns in the database in the same registration line.  I can add a data element to a fine column but cannot find out how to add data to multiple columns with different names.

  The approach I use is to open a new line and add the first element.  I then try to stay in the same record by using the thumb to the previous record vi but it isn't create one record for each item.  I'm sure this has to do with the way I'm configuration data tables and how to insert it vi data managing.

  The vi is attached.

  Thank you

  I don't have the data to test this, but I think you need to keep the data in a cluster, and then you should be able to add all columns at the same time without having to add each column at a time.

• measured LabVIEW frm data to record in a database

  Hello again... I hope I am in the right forum to ask this... Im working on another project which requires me to use LabView software (apart from the other project on the welding process)...

  This project is a solar cell of combat that will give me some current and voltage values according to some irradiation... So far, the measured data are presented and saved as excel file...

  However, I need to do another concept of backup, to ensure that the measured data are saved in another way to ensure it is not lost... (I hope my explanation makes sense...:-s)...

  My question is, is it possible to save the data measured in a LabView database?

  Thank you...

  Is there a way? Yes, but it requires you to create the database, set the tables in the database, and then download the data. There is no way of auto-la magic to convert Excel workbooks in a database. The database connectivity Toolkit (or LabSQL) is used to load the data into the database, but the database must be defined and created by you. If you don't know how to do this, you can either learn how do, or you can hire someone to do the work fo you.

  Can do you it yourself? Perhaps. You really need to sit down with some primers on the databases first in order to understand the concept, purpose and uses of their. You must also decide what system of database to use. Using Microsoft Access, or something like SQL Server (or MySQL)? Anyway, that you would need to sit down with some tutorials.

• How to remove line before Panel table with databases?

  Hi friends,

  I created the table creation of database for the list of users. Which works very well. And I also recover data that is I've stored previously and I have displayed in table format on the front. Now, I want to delete a whole line, is not a wise order, for example, now, I have a table, there total 7 rows and 5 columns. Now, I want to delete the 3 rows using by selecting the line (i.e., click anywhere in this line and press the button) that day that the rank will be remove from the database. Then remaining will again store in the database.

  I want this way is it possible or not?

  Thanks

  Instead of storing data in the database, simply remove the record that you have removed from your FP indicator and recharge the light on the database.  (The first column in my database is named ID - autoindexed, the primary key)

• Database without buy MS Access on XP

  Hello

  Really sorry to ask this, but I'm not too clued up with databases at all and can't find anything to help me in searching on the site.

  I am creation / created a demand where I store data in a database.  I have the database connectivity kit and have developed my app to run with MS Access (.accdb) connecting with udl files - files and I have MS Access 2010 on my dev PC.  However, now I want to distribute/deploy my application on the PC with ONLY Windows XP installed, or any other free software.  Essentially, the client does not want to buy MS Access.

  What are my options for making storage database but not to buy MS Access?  Clean machine XP doesn't know even what a udl file, so I'm confused.

  Can I use a database of free and open source, postgres, sqlite program?  If so, how can I join those? Can I use mdb files even if MS Access is not installed?

  Really sorry for the stupid questions, my head is just a bunch of junk at the moment with all this mdb, accdb, sql, udl, dsn stuff.  I just need someone to point me in the right direction.

  See here for the MS Access question:

  I can Access MDE files using the LabVIEW Database Connectivity Toolkit on a computer without Microso...

  There is regarding the alternatives, MySQL and MS SQL Server Express. The one you should use depends on really is the complexity of your schema, and if you have a lot of dependence on stored procedures. The last time I had checked MySQL did not have a lot of support for stored procedures.

  In addition, as an alternative to database connectivity Kit, you can also use the free LabSQL.

• continious streaming to the mysql database

  Hello

  I have LabvVIEW and LV Database Connectivity Toolkit. I'm creating a test sequence and I need to log the results and data to a mysql database. I want to ask you your opinion on what will be the most effective approach to connect to the database. I'll open connection once and then permanently in the stream of data to the database and then once I am finished, I've just will close the connection (similar to the concept of IO file in LabVIEW. Or will I open connection every time I need to connect to the database and immediately close and then open it again once I need to save the data again. SO basically, my program flow will be:

  1. opening (operator or engineer)---> this information must be connected.

  2. Select the test---> name sequence selected sequence must be connected

  3. start Test---> uut data number of series, and the result must be connected

  and so on.

  so the cycle just repeats, it may be that the operator will continue to another sequence of test, or switch to another object to measure. But all the information will be saved to the database.

  So, what will be the most effective approach of data communication? It is best to open the connection before, connect and then log the data on the fly, and then after the operator made with test, to stop the program, the connection will also be closed.

  or

  Whenever I need to connect to the database, I'll open the connection, and then close the log data (i.e. for the Login of the operator, the database connection will be opened, save the id of the operator, then closes the connection, then when a test sequence is selected, the database connection is open again and then save the name of the test sequence) and then close the connection, etc.)

  This will be my first to deal with the database and I don't know if the approach to database is the same as the approach to connect to the file using binary or text. I know that for the binary or text, it is recommended that we make data streaming, but for the database, it will follow the same concept? My concern is that these tests can last for hours. I'm not sure how stable it is to keep in now open database connection.

  Any help or opnion anywone, will be very happy. Thanks a lot in advcance!

  I think both architectures are good. Choose the best one depends on too many factors. How many connection you have simultaneously to this base? How is the load of your LAN network? How long can happen that you lost the connection with the database? The amount of data you want to transfer for each transaction?

  According to me, a third approach now is to connect the the test data for the local machine and transfer the data at the end of the trial. It is an approach to security that it is also proposed by Microsoft using the ADO SqlServer 8.Lorsque. The data group are indeed a copy of the data on the local, but I think that it is better to save data to a log file and once the acquisition is completed, transfer them to SQLServer and then kill the file.

• Windows Embedded Standard 7 - compatible database tool box?

  I'm looking at the TPC-2212 and the possibility of WES7 for a BONE and I was wondering if he will be able to use the database?

  Thank you.

  After the refinement of terminology more digging and searching I found my answer here: http://www.ni.com/white-paper/13047/en

  4. do I need to connect directly to a database of my system?

  WES7 supports saving data to a database using the LabVIEW DSC Module. Logging of database with LabVIEW DSC is designed specially for easy configuration and use. It can easily connect and connect directly to the currents a lot of relational databases such as Oracle, mySQL and Microsoft SQL. LabVIEW DSC also includes its own built-in database, Citadel, optimized for effective long-term record.

  WES7 also works with the LabVIEW Database Connectivity Toolkit, which allows more personalized creation, querying and retrieving data from any provider that adheres to the standard Microsoft AciveX Data Object (ADO), mutual FUND data base connectivity (ODBC), or linking and embedding database (OLE DB). Similar to LabVIEW DSC, the database connectivity Toolkit supports communication to common databases such as Oracle and Microsoft SQL.

  Like mutual FUNDS, several methods of communication of common database are based on Windows like ActiveX technology. For this reason, the LabVIEW Database Connectivity Toolkit does not work in time applications real LabVIEW.

  Learn more about the recording of data with LabVIEW DSC options.

  Database connectivity is always possible by using LabVIEW Real-time, but a Windows host to the intermediate address must be used; similar to the method used to obtain access to the OPC, as well as Real LabVIEW HMI - Time capabilities. Standard communication such as TCP, UDP, and variable LabVIEW shared methods are used to communicate with this Windows separate host computer.

  You can not create a table with the name "table".  It is a key word.

• Reading large data using the database connectivity

  Hello

  I use the Labview database connectivity toolkit to connect to my database sqlitev3 (I'm using ODBC). I just have to connect to the database (using the block of open_connection) and read all the values inside (using the select_data block). The problem is that my database is huge (about 2 GB), and I get this error:

  .

  What should I do? It seems that he reads the data in the memory and it doesn't have enough space for it. When I read the data I want to write to a file.

  

  Read it in pieces. Write each piece to the file, and then repeat with the next segment. Try to read and process all data in one shot is not very practical and you found out will not work.

• How to send the SQL for SQL Server statement and return data without using database connectivity Kit?

  Hi, I tried to figure out how to extract data from my SQL Server databases and reading messages and to do some tests with examples, I can get data connection type in my SQL server, but so far nothing helps.  Is it possible to get data from a SQL Server database without using the database connectivity Toolkit?  and if so, how?  are there whitepapers and/or examples of this?  So far, I can't find something that works.  Thank you.

  Jesse - what is your reason for not using the database connectivity Toolkit? It is by far the best way to recover the data.

• Problem installation database connectivity Kit

  My company manufactures in several factories around the world.  I have a problem in China and that you want to debug, and because the code is distributed in the form of exe, it is a problem.  My approach was to install a trial license of 30 days of LV2010 SP1, intend to withdraw when debugging is done.  So far, so good.  The problem is that the application requires the database connectivity Toolkit.  I downloaded a copy and tried to install.  It says it can't install because LV2010 is not installed.  Is it because of the eval license?

  If I wanted to rewrite hundreds of applications running, I could do that, but what I want is to install the DB Toolkit for a bit of troubleshooting.

  If NEITHER would alter the conditions on their license server, I would not have these problems.
