• Database connectivity Kit

  Hello

  I use the database connectivity toolkit to create a Microsoft access database.  I'm new to the Toolbox.  I've read the tutorials online and following the instructions.  I created an empty Microsoft Access file with an .mdb extension.  I also created a link to data .udl with tools > create data... in LabView and linked to the mdb file.  My code VI is attached.  I get the following error when I run the program (also attached).  I don't know what causes this error.  I appreciate your help.

  Thank you

  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:

  . VI NI_Database_API.lvlib:Rec FETCH Recordset Data (R)-> NI_Database_API.lvlibB Tools Select Data.vi-> real_web.vi-> real_web.vi.ProxyCallerADO error: 0x8007000E Exception occurred in provider: not enough memory is available to complete this operation. in .vi NI_Database_API.lvlib:Rec Fetch Recordset Data (R)-> NI_Database_API.lvlibB Tools Select Data.vi-> real_web.vi-> real_web.vi.ProxyCaller

  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.

• Database connectivity error: ADO...?

  I'm trying to export data in an Oracle database local using the Toolbox Database Connectivity.

  (I created my TEST table in the local Oracle database, I can access, write, read, etc. using SQL.) I also have the .dsn file that works with SQL)

  I get the following error:

  

  I found the problem. Not associated with LabVIEW (Duh...).

  Basically I have two copies of .tns names in two different folders. One of the files that I used to make a connection

  to the database did not have the correct login info and the other did. One who did was one I used.

• database connection status indicator

  I want to put something on the front of my program which will indicate the status of database connection. I think to ask at the tables in the list (it should be displayed), if the connection is good, it shows error. I tried and I think it works very well, but I don't know if it's the right way to do it, there may be better ways there, could someone point out he for me?

  Best regards

  You certainly don't want to open and close the connection. Maybe it will fail, but the 'real' connection is good. Maybe the real one has failed but this other works opening and closing. This could happen if the server has the maximum number of connections.

  Your connection is little go far?

  A simple method to check the connection just must have a loop that executes periodically a meaningless statement.

  

• 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

  Jon

  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 broken vi Toolkit

  Hi all

  I upgraded from LV 8.5 to 8.6 (windows XP platform) a couple of weeks and have had no problems until today when all of sudden my vi toolkit database is coming from broken, with: "one or more of the inputs needed for this function are not wired or are wired incorrectly. Display the context-sensitive Help window to see what should be the connections to this function. ' Mistakes however is not the case on all my vi using the objects in the Toolbox.

  Measures taken so far without success:

  1 mass compilation of my vi

  2 mass compilation of database Toolbox

  3 re install Database Resource Kit

  4 mass compile the directory vi.lib

  5 in the old knowladge base article Document ID: 2RO7J544, assured the latest microsoft MDAC is installed.

  Any help is appreciated as we use this receptive toolkit.

  Hi Chris,

  Thanks for the reply and I hope that your well.

  I need to try to understand something, when you say that the LabVIEW 8.6 upgrade have you improved the Toolbox?

  Toolkit LabVIEW Database Connectivity 1.0.2 is for LabVIEW 8.6. If, on the other hand your trying to use LabVIEW 8.6 with DC Toolkit 1.0.1 so I think that they are not officially compatible. However, these links may be of interest knowledge base: (after all, they are just screws). However, to say this - if you read the Readme for the new toolkit, that many things have changed for LabVIEW 8.6 - so becareful.

  You will have to manually copy all the files in one version of LabVIEW to another. Use the following instructions to achieve:

  1. Install the database connectivity toolset to the version of LabVIEW, say X.
  2. Copy the following files/directories in the directories right in the latest version of LabVIEW, say Y.
     • Copy the data directory from \LabVIEW X\vi.lib\addons\ to \LabVIEW Y\vi.lib\addons\
     • Copy the file database.llb \LabVIEW X\project\ to \LabVIEW Y\project\
     • Copy the data directory from \LabVIEW X\examples\ to \LabVIEW Y\examples\

  "Update to the latest MDAC will solve this problem."

  I would also check that you have installed the Toolkit for LabVIEW 8.6 - toolkits are now specific for labVIEW 8.6. Then maybe try to reinstall and the Toolbox for LV8.6.

  Hope this helps and please let me know (Please specify a little more).

• Drop database connectable to including the file system data sheets files

  I did experiments with the connectable Oracle12c to database functionality and have noticed that when I "drop database connectable to pdb1 including datafiles', I get the message that the database snap-in has been dropped."  I also see that all files in the tablespace for the PDB except the SYSTEM data file have been deleted.

  
  I want to remove the folder that has been used for the pluggable database after that the PDB fell, but cannot because the file SYSTEM data is left behind.

  Is it possible to delete the data file SYSTEM for a pluggable database once he fell?  Or this part forever from the database of the container?

  Thank you

  This forum works on a Server Windows 2012.

  Thanks for the Bug information.  There is no error in the alert.log file, but I found a trace file with:

  ORA-01265: cannot remove the D:\ETC\ETC\SYSTEM01 DATA. DBF

  ORA-27056: could not delete file

  OSD-04024: cannot delete the file.

  S/O-error: (32 OS) the process cannot access the file because it is being used by another process.

  This seems to be the same problem as described in bug 17659954, so I can follow in investigating the recommendations of bug

• How to create interactive reports database connection?

  I installed the interactive web reporting client of hyperion workspace.

  When I create a new document for creating interactive reports in the workspace file > new > Document > create a document of interactive report > data source >

  He is asked to select the database connection, which I am unable to create. Please guide me.

  Thanks in advance.

  Hello

  To create the ECAS, you first have to decide whether to use an ODBC connection or ike Client.Then Oracle create using the Interactive Studio Reporting of the OCÉ customer. Then check if the BQY works with this OCE connection.

  After that you need to publish (import) in the workspace. Also, in the workspace, you must make entries of data (DAS entries) that will allow to use the drivers to connect to the database of the ECO.

  Then, you must publish the BQY and associate it with the ECO.

  HTH,

  Thank you

• How to add a second database connection

  Hello

  I added a new database connection. Then, I want to create tables business components but I do not see the schema of the database connection newly added in the drop-down list schema.

  
  

  Is there something else to do to be able to add a second connection to the base?

  Thank you

  JDev 11.1.1.6

  DB connections are strongly coupled with modules of the application. The best way would be to create a new project template and use this second model to access the database. Then, you use each application as application root module modules so that each gets its own connection.

  If you need to have these two dbs data in a table or query, you must use a link db or synonym to access data from ad of your DB connections.

• How to question dignosis between P6 web and database connection problem.

  Hi all

  Initially we have access to P6 via a URl server http://ip: 7001 / p6

  We have migrated our server to the new support. now above the URL does not work.

  but instead of the IP if I get p6 URL, server name opens http://servername:7001 / p6

  But I am not able to connect. (I'm not able to extend the button Advanced also to see the name of the database).

  I think that P6 does not connect to the database. (Our database is available on another machine and I can ping this machine server request P6).

  Please let me know, how can I diagnose this problem of connectivity.

  
  

  On the server where P6 is installed, run the dbconfigpv.sh/cmd again and reconfigure the database connection. Also, run adminpv.sh/cmd. Login with privuser and check the connection to the base there. Test to verify that it is able to connect to the database. If you change any setting then restart weblogic server for the change to take into account.
