Database connectivity toolset and microsoft access

Bonjour,
je suis débutante labview et j'aurais besoin d'aide...
voici mon pb:
j'ai créé une table sous microsoft access et j'aimerais lire les données à partir de labview en utilisant "database connectivity toolset". les vi utilisés sontpen connection, select data et close connection.
le vi "open connection" demande le 'connection information': j'ai donc donné le chemin ou se trouve mon fichier .udl
ce fichier udl est configuré comme cela:
fournisseur: microsoft jet et connexion: le chemin ou se trouve le fichier access.
mais ca ne marche pas! j'ai une erreur apres le vi select data, qui me dit 'erreur syntax'
je ne sais pas si j'utilise les bons vi....
merci pour une réponse rapide.

Bonjour,
Tout d'abord, vous devez vérifiez si la création du fichier UDL est correcte. Ci-dessous une note d'application décrivant étape par étape cette procédure:
* Creating a Microsoft Data Link file (.UDL) for Connecting to Microsoft Access in LabVIEW
http://digital.ni.com/public.nsf/websearch/1D5EB4DCBD13106486256B9D005E11B0?OpenDocument
Ensuite, testez l'exemple standard "Connection example.vi" fourni avec le toolkit Database Connectivity.
Dans LabVIEW, allez dans le Menu Aide >> Recherche d'exemples ... puis sélectionnez Toolkits & Modules >> Connection aux bases de données >> Connection example.
Si la connection échoue, l'exemple doit renvoyer une erreur avec un code et un descriptif. Ces informations sont indispensables pour débuter un débuggage (l
es codes d'erreurs classiques sont référencés sur le web et des notes d'applications sont fournies pour les corriger).

Database connectivity toolset and nested transaction

Is it possible to make nested transactions with the Database Connectivity Toolset ?
By nested transactions I mean that I want to open a transaction inside a transaction.
I use LabVIEW 6.1 and Database Connectivity Toolset 1.1
Any ideas are welcome.

You may be able to do this in a different manner. Your options depend on how the database has structured the data. For example you can have a table defining "measures", another table defining "measure setps" and so on.
Each measure has an ID (MID) and each measure step has an ID (MSID) and these can be related to each other to provide the hierarchy. So in this case you could just get a measure, then query for all the measure steps that match (the MID and MSID) and sort them based on some attribute/criteria and work down in that manner.
This would provide a clean data architecture and enable you to reuse steps in multiple measures if you needed to. I'm not sure how your database is building the hierarchy, in the end there are some parent ch
ild relationships defined ... these would be very similar to the IDs referred to above.
Like you said, had to explain without a picture.

Memory leak when using database connectivity toolset and ODBC driver for MySQL

The "DB Tools Close Connection VI" does not free all the memory used when "DB Tools Open Connection VI" connects to "MySQL ODBC Driver 3.51".
I have made a small program that only opens and close the connection that I run continously and it's slowly eating all my memory. No error is given from any of the VI's. (I'm using the "Simple Error Handler VI" to check for errors.)
I've also tried different options in the DSN configuration without any results.

I've duplicated the OPs example: a simple VI that opens and closes a connection. I can say this definately causes a memory leak.

How to get a recordset defined by primarykeys using the LabVIEW Database Connectivity Toolset?

Hi folks.
I'm using LabVIEW with the LabVIEW Db Toolset and Microsoft Access. The table contains 18 columns with a growing nr of rows.Now I want to get the whole recordset containing all columns defined by my primary keys. My SQL-statement is sofar:
SELECT ALL FROM IMPULS_STATOR WHERE FAB = [string] AND LDATE = [datestring] AND ADATE = [datestring]
But every time I end up with an error message saying "Invalid string: specified field does not exist or contains an unsupported character". I mutated the statement several times, adding or removing spaces, colons, etc.
What am I doing wrong?
Thanks in advance

Thanks, Dennis.
Unfortunately, I`m still encountering some problems with the DateValue function. My date/time field has this format: yyyy-mm-dd hh:nn:ss . If I use DateValue, nothing will be returned. Changing the format to yyyy-mm-dd in the Access DB didn`t help and I do need the time. Combining DateValue and TimeValue let to several errors. Using only TimeValue did not help me out. LabVIEW does not indicate errors anymore, therefore the syntax should be fine. But I don`t get any information back from my database.

When using the Database Connectivity Toolset, reads and writes with long binary fields are incompatible.

I am trying to write LabVIEW Variants to long binary fields in a .mdb file using the Database Connectivity Toolset. I get errors when trying to convert the field back to a variant after reading it back from the database.
I next tried flattening the variant before writing it and ultimately wound up doing the following experiments:
1) If I use DB Tools Insert Data to write an ordinary string and read it back using a DB Tools Select Data, the string is converted from ASCII to Unicode.
2) If I use DB Tools Create Parameterized Query to do an INSERT INTO or an UPDATE operation, specifying that the data is BINARY, then read it back using a DB Tools Select Data,
the length of the string is prepended to the string itself as a big-endian four-byte integer.
I can't think of any way to do a parameterized read, although the mechanism exists to return data via parameters.
Presuming that this same problem affects Variants when they are written to the database and read back, I could see why I get an error. At least with flattened strings I have the option of discarding the length bytes from the beginning of the string.
Am I missing something here?

David,
You've missed the point. When a data item is flattened to a string, the first four bytes of the string are expected to be the total length of the string in big-endian binary format. What is happening here is that preceding this four-byte length code is another copy of the same four bytes. If an ordinary string, "abcdefg" is used in place of the flattened data item, it will come back as <00><00><00><07>abcdefg. Here I've used to represent a byte in hexadecimal notation. This problem has nothing to do with flattening and unflattening data items. It has only to do with the data channel consisting of writing to and reading from the database.
I am attaching three files that you can use to demonstrate the problem. The VI file c
ontains an explanation of the problem and instructions for installing and operating the demonstration.

Hi Satish
It could be an issue with the driver.
You can try with the OLEDB n Oracle native connection to test if the issue persists.
Also you can refer to the [Troubleshooting Database Connectivity for Crystal Reports|http://www.sdn.sap.com/irj/boc/index?rid=/library/uuid/d05b3bb7-0f28-2c10-4ea3-84dbdc4e414e&overridelayout=true]

Database connectivity toolset

Hi,
I am using the VI "DB Tools Select Data" from the database connectivity toolset. And I have a problem with the VI "DB Tools Execute Query" that is included. I would like to select a specific column from a specific table in my database and it is ok so long the name of the table is just one work, example "Names", but if the name of the table consists of two words ("Last Name") I get error, the message says that it can't find the table Last, i.e. not the whole string is read, just the first part. How can I manage to get the "Conn Execute.vi" to read the whole SQL query? Any suggestions?

As far as I know and what I experienced, there are no blanks allowed (and some other special characters), both in table names and column names.
Just replace the blanks with an underscore and it should work.

Working with InDesign and Microsoft Access Databases

I was wondering if there’s anyway to synchronize Adobe InDesign with Microsoft Access in a way that when changes are made to the INDD file they would automatically be updated in the database. Does Anyone have any ideas on this? Is there a third party plugin that would accomplish this or would I need to export xml out of InDesign?

InCopy would be indeed the best solution for you. InCopy is the little brother of InDesign, But both need to be in the same version to work together flawless.
InCopy is much cheaper and simpler than InDesign as it is missing layout capacity, but both of you need to understand both applications.
Generally, if 2 persons are working on the same document they should have the same versions between 2 InDesigns or between InDesign and InCopy, any workflow where IDML is needed should be avoided.
Why are there so many corrections in your present workflow? If you make your Word Document correct and set it up with styles without any manual format overrides, no hyphenation, no several continuous returns it should reduce the number of corrections on the first place.

Crystal reports server and microsoft access db

Hi
I have created a Crystal Report using Crystal Reports XI. In terms of a datasource I simply used a unc path to the actual mdb file.
I can open the report local on the PC in CR XI and the report runs no problem however I have deployed to our Crystal Reports server XI so that users can use it.
The problem is that when I try to run the report from the Info view console it keeps asking me for a user id and password. I have logged into the CMC admin console and looked at the properites of the report and the process/database tab however not matter what I configure in there it either asks for the username and password or says invlaid object when I try to view the report.
I have created other reports which have used an SQL database as the data source and published them to the CR Server and they work no problem so I am guessing I need to change something for using an Access DB as the dataource. Not usr eif that change is in Crystal Reports XI or Crystal Reports Server?
Can anyone help?
Many thanks

Listener EA2: database connection pool and connection revalidation

Hi all,
As one can expect from early adopter release there could be some bugs but I can't find any references in forum to my situation:
* My 11g XE database and listener are starting as windows services when server boots operating system (Windows Server 2003 R2).
* I configured my web server (unsupported Jetty 9.0.0.M1) to start as windows service when operating system starts.
* Apex Listener 2.0.0.268.17.05 configured to connect with XE using JDBC thin driver with default settings (initial pool size 3, max statements 10, min connections 1, max connections 10, inactivity timeout 1800, abandoned connection timeout 900)
* Because web server starts a bit faster than Oracle database when apex connects first time it gets "ORA-12528, TNS:listener: all appropriate instances are blocking new connections" (could be that database still starting but already registered service with listener)
* From listener.log file I can see that all further connections made from Apex listener succeeds
* When I try to open any apex page with browser I am getting 404 error and apex listener logs error (*time is 2 days after system startup*):

* For some reason apex listener keeps first connection status and won't try to establish new connection if first attempt finished with ORA-12528
* The same scenario is valid when at time of web server start oracle database/listener is not available - even if database and listener starts and apex successfully establishes further connections all apex pages gets 404 error
* If I restart web server windows service (while oracle db and listener still running) browser opens apex pages without errors and apex listener does not log any errors
* I know that I can avoid this error delaying start of web server windows service but it would be nice to have production release 2.x without such bugs

Hi,
Is there any way to use the connection pool or Datasource while connecting to database?If I am using a stateless sesssion bean and using a Data Access layer which just creates a database session to write the persistence toplink objects how I can make use of application server connection pool?Hi Vinod,
Yes, TopLink allows you to use the app server's connection pooling and transaction services. Chapter 2 of the Oracle9iAS TopLink Foundation Library Guide provides details as do the TopLink examples. The easiest way to set this up is by using the sessions.xml file. The sample XML below is from the file <toplink903>\examples\ias\examples\ejb\sessionbean\sessions.xml. Here we are adding the datasource defined in OC4J and specifying that we are using the OC4J transaction controller also.
<login>
<user-name>sa</user-name>
<password></password>
<datasource>java:comp/env/jdbc/ejbJTSDataSource</datasource>
<uses-external-transaction-controller>true</uses-external-transaction-controller>
<uses-external-connection-pool>true</uses-external-connection-pool>
</login>
<external-transaction-controller-class>oracle.toplink.jts.oracle9i.Oracle9iJTSExternalTransactionController</external-transaction-controller-class>
When using this approach you need to change your TopLink code slightly in the EJB methods:
a. Acquire the ACTIVE unit of work from the server
session (again, see the EmployeeSessionEJB code
example) with something like:
UnitOfWork uow = clientSession.getActiveUnitOfWork();
b. Calls to uow.commit() can be ommitted or commented out
because the EJB will handle this. Note that of course
the methods you create in the EJB that are using this
approach must have TX Required (default).
Hope this helps.

Questions about the future directions of InfoPath and Microsoft Access

Because I have been confused about the future directions of InfoPath and Access, I wrote a short blog post, which I have pasted below. My question is, can Microsoft provide some more guidance on Access vs InfoPath? If Access is indeed the
the future direction, can you please provide some pointers to resources that can help us transition.
A Short Review of MS Access, SharePoint ,InfoPath (2013)
After the November 2012 SharePoint Conference in Las Vegas (#spc12) there were a number of blog posts and people saying that Access 2013 was great and would be replacing InfoPath.
Marc Anderson and
Ruven
Gotz have short posts summarizing #SPC12 and touch on the subject of InfoPath and Access. I also spoke with several individuals shortly after #SPC12 and they were excited about Access 2013.
Since I rely heavily on InfoPath for much of what I do, I wanted to kick the tires and see what everyone was talking about. First, a few notes about SharePoint 2013 and Office 2013.
Microsoft should rename Access: If you have tried to
bing the word Access, then you know that the search results are overwhelming, because the word "access" is used for so many other purposes.
Use the RTM version of Office 2013! I was performing my investigations by leveraging the Office 365 Beta and the Office Applications that come with it. Not much was working! After I uninstalled the Beta
version of Office 2013 and Installed the RTM version everything seemed to work.
Windows 7 and IE 9.0: The drag & drop that is being touted as
"manna from heaven" seems to work well with Firefox, Safari, Chrome, and IE 10, but it does
not work with IE 9!
Non Microsoft browsers are still second class citizens (except for the drag & drop): Microsoft has finally done away with the Active X's for datasheet view (that is brilliant!) One can now see the newly
minted datasheet view in many browsers. But I still find that one needs to be in IE to do a number of key manual opeartions. For example pasting numerous rows of data from a spreadsheet into the new sheet view works only in IE.
Access 2013
Microsoft Access is touted as a non developer tool. I know a number of people who are on the business side and love Access. These people will like the renewed energy that Microsoft has applied to Access. One should note that conceptually
this functionality existed in SharePoint 2010. Here is what I see that is new:
+The new version works better:Although I haven't tested it fully, it seems that many more features that work on the Desktop version of Access, now work in the published Web Application which is hosted by SharePoint 2013.
+The new version has fairly robust browser based forms: End users can now fill in data using forms that are rendered in the browser.
+The published version that resides in SharePoint now uses its own SQL server tables. So the engine appears to be SQL Server, not a modified version of Access built for a server. This stands to be quite robust, but I imagine
that some quirks will surface due to new model.
The limitations are:
- Access is pretty much its own application and does not integrate with SharePoint building blocks. For example, an Access table is not easy to integrate with a SharePoint workflow. Further, although Access forms now are visible
in a browser, they are not nearly as rich as InfoPath forms. InfoPath forms cannot easily integrate with the Access tables. In order to integrate SharePoint features and Access, one needs to tie SharePoint list(s) to Access as data sources.
This overcomplicates the model and one may very well run into synchronization issues.
In short, although I believe there will be some people who will be happy with newly minted Access, I do not think that Access will be able to replace InfoPath and Workflow technologies. I do agree that Microsoft does not seem to have put much energy into
InfoPath. If they leave a vacuum in this space, then others may very well take over, for instance Nintex Forms.

Although I agree with the comments made by Ruven and Marc after the conference please note that those blog posts are their own personal opinions and that they don't work for Microsoft. A lot of people have asked Microsoft to clarify the future of InfoPath
and the response up until now has been a deafening silence. In my opinion speculations about Access replacing InfoPath are premature.
I should also point out that most of your comments about Access 2013 above are actually about Access Services in SharePoint Server 2013. Access Services are NOT Access they are a shared service offering in SharePoint that convert and publish Access
databases and forms. As you point out once an Access database is published through Access services it is converted to SQL Server and no longer resides in Access. Of course I don't work for Microsoft either so these are all just my personal opinion.
Having said that I doubt you will get the confirmation/response that you are hoping for from any official Microsoft channel.

Database Connectivity Toolset-Fetching Data from Database

Hello guys,
Currently I am doing some applications that include with database manipulation. The data that I am using now coming from Microsoft Access.
My Idea is to fetch the data from the specified table, specified column and specified row.... yeah we could do it using SQL query that we wrote on the Block Diagram...but that will be apply for the one condition that we set.
How about for the next time when we want to pull data from the same database but from different table/column/row using the same application..yeah we have to change the sql query
Why don't we use 'ring' in Front Panel to choose the database we want like to...
example
If we choose
Dominant = Right
Age = 25-34
Sex=Female
Weight= 50-69
Height= 175-184
Then the answer that will come out might be 78 in numeric indicator
So and the next time if I choose
If we choose
Dominant = Left
Age = 25-34
Sex=Male
Weight= 50-69
Height= 175-184
Then the answer will be 77 in numeric indicator...
So...my questions is simple....how to do it....have anyone here try to use ring to make selections in their database
I'll attach my empty applcation so that you all can see the Front Panel...and what exactly my Idea is...
TQ

I couldn't look at your VI (7.0), but you can read (and change) the strings in a ring by using a property node.
To create one, right click on the control or the terminal and select Create>>Property Node. Then, click on the property and find Strings[] in the list. This is an array of all the strings in the ring. You can wire it, along with the ring value, into Index Array and you will get the string you chose.
You can now use this string to build your SQL query, no need for numbers and codes.
You can further customize this by using different strings for each field. For example, you can have one ring which will select the field, and based on that, another ring will now have only the values relevant to that field.
You can save these values in an array and that way have an unlimited query.
Correct me if I'm wrong, but don't the DB tools allow you to extract data directly (For instance, the DB Tools Select Data VI)? Shouldn't this allow you to extract all the info you need?
Try to take over the world!
