Regd: Database in Labview

How do I setup database connectivity in Labview ?? Since I am new to labview please help me to find it

Hi,
You can use the Windows ODBC connection. Its in windows control panel-> Administrative Tool-> (Data Sources) ODBC.
Before that you sholud to install Microsoft Access or SQL Server database. Then you can start configuring ODBC.
If you have any further clarification please feel free replay to post.

How to create a database using LabView?

Hy
I have to do a project in which i have to create a database with the situation of the students (name,age...) using ONLY LabView.I need to enter tha students using labview, to save the database using labview.... I have to figure it out how to do this, but .... no idea. Also i have to make a search in that database. If you can help me, i apreciate that or if you know a link on the web about something like this
Thanks,

Labview configuration files are very easy to use and can hold any type of information you wish. There are functions in the File palette ready to use for configuration files. A configuration file is similar to a registry entry. You can have sections and keys. So you can create a section called "Data1" and keys called "Name", "Age", etc. Create the same for a new section called "Data2", and so on. The functions are useful for writing the config file and reading from the file. To read a certain piece of data, just supply the section name and the key name. So you could ask for section "Data20", key "Name", and you would get the 20th name in the database (config file). This way you don't have to write code to search the database for certain items, the functions do it for you and they are already written. Look into config files. They are very easy to use, very useful, and very underused even by the most experienced LV programmer.

How to connect mysql database to labview and plot the graph

Hi all,
I am doing my final year project about labview. I need to connect my mysql workbench database to labview and plotting two sinwave in same graph. I can already connected my labview to mysql and showing the data in labview table.But I need to plot the two sinwave in on graph according to table data. Eg: table data&colon;      timestamp   wind speed wind direction
                                                                                                                                                                                                 2004-01-01        0.5                 56
                                                                                                                                                                                                  2004-01-01         0.6                 60
The attachemtn vi is about inserting file and plot the graph. And now I want plotting the sinwave using table data and the wind speed Y-axis,wind direction Y-axis in both side of my graph and the X-axis is showing the whole day timing like 00:00:00-24:00:00.  Can anybody combine these 2 vi to polting the graph according table data not according to file data.Thanks

I havent done much database with labview in a few years and am looking for any pitfalls to avoide. I need do choose the right DBMS access, mySql ..... and also know if there are know issues og the database toolkit. Has anyone had any problems or suscess using 8.5 and databasing. I will be writing moderate amounts of data to the data base, I will be updating fields several times per minute and the system will run mostly continous 24/7

Hi Paul,
You should be able to use the Database Connectivity Toolkit with LabVIEW 8.5 just fine. There is a list of supported databases here so you should be able to select the database you want.

Is is possible to access channels from a CAN database in labview with NI USB 8473s

Hello,
I would like to know whether is possible to access a CAN database, which is uploaded through MAX, in labview.
More specifically, I have uploaded my CAN database in MAX and I want to have access to each specific channel in labview.
i.e according to picture, I would like to have access to n_Motor_InsRpm channel of E1_L0_1 (motor speed) in Labview, so I can set and transmit a speed value through CAN. Could that be possible with NI USB 8473 s? If yes, is there any simple example in Labview ?
Thanks for your Help

Write to Citadel database from LabVIEW?

Hi. I'm a newbie when it comes to Lookout and the Citadel database... so here's my question for you all:
We have various labview applications that log data from instruments. We would like to be able to take this data and store it as "tags" in a Citadel database.
What do you think is the best way to do this?
There are ODBC drivers for the Citadel database, but they appear to only allow you to query the database to retrieve values... you can't write data to the database (so its read-only).
Are they any "Lookout VIs" or Citadel VIs that can write to the Citadel DB from LabVIEW? Or a DLL or something?
Any ideas?
regards,
John Paul

Very nice question John Paul. I take it you already have Lookout and LabVIEW. In this case, with the latest versions of either, simply use the LabVIEW datasocket to publish the items on your front panel. Lookout then can subscribe to these once you register the LabVIEW computer. Once you have subscribed to them in Lookout, you are then able to set up logging. You may need to create an expression object to route the data to citadel.
If you just want to use LabVIEW and the Citadel database, you might try VI Logger. This works in our configuration utility - MAX, and also comes with a set of VIs for LabVIEW. One caveot, the Citadel database in VI logger is newer (and faster) than the Citadel database in Lookout. I believe NI is working to synchronize
the version in the future, and its hard to say when. So till then, you would not be able to merge data in the dislike citadel databases. However, you can always use and ODBC call set to extract from both and store in a more permanent SQL database such as access, oracle, ms back office, etc.

How to create an SQL Database using LabVIEW??

Hi all,
I have been using LabVIEW for quite a long time but now I am doing something which I am totally new to. I have a VI which gives out a table as output. What I am trying to do is, I want to create an SQL databse and save this table in the database and I want to pass the value of this table to the SQL Database once in every 24 hours. As I dont have any knowledge of My SQL I am totally stuck.
Can anyone help me by telling me how to do this.?? An example code will be well appreciated.
Regards,
Nitz..

Hi Nitzz,
what have you done and where do you have problems? Did you make a search here in the forum?

Accessing mySQL database from Labview PDA

Hi,
Has anyone tried writing data to a mySQL database or any other database for that matter using the Labview PDA module? I know it's easy to do from Labview and you have to download the ODBC drivers to get it working but I don't think these drivers are available for Windows Mobile (I've seen XP and Linux drivers only). Any help would be appreciated.
Thanks

Hello,
I don't have experience with this, but you might look into the following:
1. remote connections: http://www.geekzone.co.nz/content.asp?contentid=2656
2. this thread seems to indicate .NET doesn't support it yet (but it's over a year old...): http://forums.mysql.com/read.php?38,73109,73109
3. Another option - you can use VI Server to have your PDA VI call a VI on your host machine if they are networked... there is an example of this that ships with LabVIEW PDA I think - check it out! Thus, if the db is on your host machine, you could write your host VI, and have your PDA VI call it etc.
I hope this helps!

Transferring a lot of data from Access Database to Labview

I need to transfer 500000 -> 1000000 values in a Access database table to Labview. The values are selected using a query which is very fast if run in Access itself, but from Labview it's very slow. Obviously the connection between Labview and Access is the slow point.
Im using the NI Database connectivity toolset and a UDL file defines the connection. Microsoft Jet 4.0 OLE DB Provider is used.
To be honest i dont know what that really means, just that it normally works but now its stupidly slow for so much data.
Thanks for any help.
Rob

One of my continual gripes with the DBCT is it's poor behavior on large data sets. See NI's response here:
http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/862567530005f0a186256a33006b917a?OpenDocument
Actually, I wouldn't find it nearly so annoying but for the part that says "In most database books you are told not to return large recordsets...". I prefer the freedom to make a mess of things myself, thanks.
On the plus side, the VI referenced in the article is fairly efficient, you just have to deal with type conversion once things have been moved into LabVIEW.

dear all,
i want to store some data that is in my fornt pannel to sql server, i am using labview 7.1 version
please help me for that

Option 1: LabSQL
Option 2: NI's Database Toolkit (though I don't think you can get a LabVIEW 7.1 compatible version - you'll need to check with you local NI rep).
Next time please do a search. This question has come up many times. Searching is not difficult.

Compact MC Access Database with labview

Hello,
How do I compact an MS Access programatically from labview to reduce its ballooning size? I have the database connectivity toolkit.
Thanks,
Ron

What datatypes are you storing? Using the wrong datatype can cause all kinds of size problems--as in the datafile expanding at a rate several times the size of the data you're putting in it...
Mike...
PS: If you are running Windows you have everything that you need. Access is not actually a database package. It's an application development package for creating programs using Jet. Jet is the DBMS that Access uses, and Jet is installed by default with Windows.

Database and labview

can labview 2009 be used to devolop an expert database management system with fuzzy quering capability?
Solved!
Go to Solution.

LabVIEW is a full-fledged programming language. Like C, C++, C#, Java, etc. With respect to your specific objective, nothing can really be said beyond that. You would need to design your system and determine what you need from a programming language, look at the various possibilites and then decide for yourself which is the best route to take. One could just as well ask "Can C be used to develop an expert database management system with fuzzy querying capability?". How would you answer that?

Find attached example. It was converted from 6 to 5. Therefore, let me know if it's not working and I'll post a screen capture of its block diagram. The example replaces the last entry in one table containing one string column.

Using SQLplus command in LabView Database toolkit

Hi ,
I would like to ask something but before that this is my set up background
OS : Win 7,
LabVIEW : 2012
I have successfully connected with Oracle database using Labview Database toolkit.
The problem now is since I need to query the data from the database,
it will takes time for the labview to process it (since there is so much data in a specific table),
let say that the table in database is "Serial Number", and the data that I want from that table is "SN123"
if I query the data from that table, the labview will process it in a long time since it will not only give me "SN123" but also other data inside the "Serial Number" table.
(Refer to attachment)
but if in SQLplus, there is a command that can be execute to specifically call the "SN123" data,
For the SQLplus, the steps to retrieve the data is like this:
1. Key in the command to get the ID of the "SN123"
2. Key in the command "SN123" ID to retrieve the data.
I wonder if there is a way to put this command on labview database so it will be faster to retrieve the data.

An instrument driver written in Labview, is not the same as a instrument driver used by say Windows. A Labview instrument driver uses standard Labview functions to send SCPI commands to the instrument. You can learn a lot about the instrument by looking into the Labview instrument driver, and how it sends the commands to the instrument. But having the instrument programming manual at hands is also important.
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
