attached is my vi. since i'm really new to programming and labview, can please somebody advise me about my vi. I will use this vi to record minutes of meeting to a mysql database. the dalog_resp.vi is used to fill the responsible string.
I need to display all mysql data into a table and i need to short the data based on project, meeting date, status and responsbile (i'm thinking to use combo box). e.q if i choose "SAM" from responsible combo box, i want the table only show the data contain SAM value. And i have another problem...when i put the boolean button into a cluster, it won't call the dialog_resp.vi
Please advice me...
Thank you
Regards
Ijan

Inserting data into a MySQL database

Hi. I am currently working on a group project and know very little about java to be honest
I'm trying to insert records into a local MySQL database, but I'm having trouble.
When the application is started, a connection is made to the database, which, as far as I can tell is successful. The user adds the data through a method in a console class which then passes the parameters to 'insertCustomer' method in class DatabaseIO.
Connection code from DatabaseIO class
public static void openDatabase(){
//          start by making the connection
          try{
               //System.out.println("setting up class");
               Class.forName("com.mysql.jdbc.Driver");
          catch(Exception e){
               System.out.println("Driver set up error" + e);
          try{
               url="jdbc:mysql://localhost:3306/db0611426";
               con=DriverManager.getConnection(url,"root","");
               System.out.println("setting up database");
               Opened = true;
          catch (Exception e){
               System.out.println("database connection error"+ e);

Update command overwrites 1st record in mysql database

hi
I'm having a bit of a problem with a form I created in livecycle designer.
I have connected the form to a MySQL database.
whenever I try to update a record , retrieved via navigation buttons or search box, the 1st record in the mysql database is overwritten.
I'm using the xfa.sourceSet.DataConnection.update() with and an click event
I have my Stay BOF and Stay EOF set on the data connections.
I'm not sure what I am doing wrong.
The forms Data connections are using sql select query because the table in the database has an auto incrementing column.
any suggestions you guys provide will be appreciated.

Guys, I am still racking my brain. I have taken some screenshots to show you how I have my database tables set up. I was able to get the tables over to the InnoDB type so I can make foreign keys. Here is how I currently have them setup, can someone check this out and see if it's correct?
Table 1 (carinfo)
Table 2 (images)
Thanks

Mysql database, counting records

Hi!
I have to store measured data to MySQL database. During this process I would like to count a number of records in a database table. It is also necessary to filter records. I'm using the SQL statement as follows:
SELECT COUNT (fieldname) AS cnt FROM table WHERE condition
Because I haven't got any result I've created a small database "mysweetdb" and table "icecream" to test my VIs (see picture bellow).
The VI is attached. The result of counting is a 2D array (DB Tools Fetch Recordset Data.VI output) with one element (one row and one column). This element contains no data.
I usually don't give up easily so I've created a similar MS ACCESS database and counted data in it. I've got a correct answer: 3. So it might be possible that there is something wrong with MySQL driver. But I've created a small Delphi project and I've counted records in MySQL database and MS ACCESS database. Both results were correct.
Can anyone explain where is the problem in communication between LabView and MySQL database?
Versions: XAMPP for Windows 1.7.3, LabView Developer Suite 2010 SP1, MySQL 5.1 ODBC driver
Thanks in advance for your suggestions.

ContDivConsult,
thank you for your answer. An updated version of my VI is attached. It uses two options: LabSQL library and DB Connectivity Toolkit. LabSQL gives correct results.

MySQL database record hits counter?

Can I find out how many times a record from the MySQL databse was called and displayed on a web browser?Basically a MySQL database record hits counter. I’m using PHP/MySQL.

>to the two files that were created
>Two files?
Yes 2 files. In Dreamweaver CS3 & CS4 When using the "Insertà Data Objectsà Master Detail Page Set" function you must create two files:
1. results.php
2. detail.php
It appears that these two files work together hand in hand. You did not specify where nor how to include an update record set that gets executed every time another record set that I want to count fires. So I combined the two as one until it was clarified.

Recording events in mySQL database?

I am new to Java and would like to know if the following can be done:
We have a web page where the user chooses to watch different Windows Media Files using a Java menu system (not written by me).
Is it possible to record what the user is doing (i.e. which media files they are choosing) in a mySQL database? I would normally do this with PHP, but as all the action is happening once the page has loaded I don't think that will work.
Thanks in advance!

Sure it's possible if you notice the events and can pass on the actions to a component that does the writing.
You can do it in PHP - unless it uses some magic to switch the embedded movies somehow, a new page has to be requested for a movie. If it all runs within the applet (I hope that this is what you mean, and not Javascript) and you can't modify it, then you can't, unless you can convince your webserver to log to the DB.

Php/MySQL database insert record issue...

I have a php page that adds an "order" to a mysql database table (orders). One text field in the form is for tires/wheels. The description of the wheels often includes the " symbol for inches after a number....Everything submits fine, however when I look at the page that displays the orders all the data after the " symbol including the " symbol is gone... DOes anyone have any idea why this may be happening? It is requiring us to return and edit that area repeatedly. Any help is appreciated greatly. Thanks for your time.

Ok, so just to summarize so I am understanding this correctly. You have an ordering page for tires/wheels. A customer places an order for tires/wheels and the data is submitted successfully and this includes a symbol for measurement (in.). But on another summary page the symbol is returning a blank value.
If this is correct we need to see:
- First, the code that is inserting the symbol to the database table in question
- Second, the query and code where you are printing the data to the screen.

Using MySQL database in Jdeveloper

I am using MySQl database in my applicaion.I have successfully created connection to the database and have created entity beans from the tables and a session bean as well to use the entity beans
now when i am trying to call persistEntity(object obj) of session bean, basically to insert records into tables.
i am getting following exception :
Internal Exception: com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near '"tdmce_approval_status" (APPROVALLEVEL, DOCREFNO, STATUS, COMMEError Code: 1064
Call:INSERT INTO "tdmce_approval_status" (APPROVALLEVEL, DOCREFNO, STATUS, COMMENTS, DMCETYPE, ACTIONDATE) VALUES (?, ?, ?, ?, ?, ?)
bind => [1, 12355, Approved, abcd, import, 12/03/2008]
i believe this insert query is automatically generated by Jdeveloper. have tried executing the same query in sql sheet it has worked perfectly fine.
Can any one please suggest on this ?

Don't get a result set from a query to mySql database

Hello everyone,
I am writing a program in which i refer to a mySql database.
I encountered a problem using the executeQuery in which i don't get a resultSet at the end of the run,
instead i get a null.
gust for the record, the api says that it will never return null(se 6), also i queried the DB with a mySql client and the data is there
and when i use execute("") everything works fine.
I just can't get my wished result.
the peace of code I am referring to is here, please feel free to say if you need more code...
public static ResultSet getAccountResSet(int id) throws SQLException {
         //String query = "SELECT acctNum, acctOwnerId, acctOwnerName, balance, acctType, creditLimit, yearlyInterest, duration, creationDate, relatedCheckingAccoun FROM accounts WHERE acctNum="+id;
         String query = "select * from accounts where id="+id;
         ResultSet rs = statement.executeQuery(query);//this line falls, rs is null and i get null pointer exception
         return rs;
    }thanks for you help :)
Edited by: gizmokaka on Mar 29, 2008 8:37 AM

Maybe it's not the function executeQuery(query) that gives you the nullpointer. I think it may be that there is no connection to the DB, in which case the statement variable is null. Call to a method through this variable will trigger a nullpointer. Could you please post the exception text here? It may tell you where the NullPointerException occurs.

Send form data via email after posting to MySQL database

I have created a form in DreamweaverMX 2004 and then tied it to mySQL database so that on submit the data posts to the database.
This works fine. It also goes to a "success" page just fine. I then added in some php code to also email a few of the fields from the form to a specific email address. This functions correctly using this code below (the email does go - the "from" email address has my login for MySQL database) EXCEPT that the data from the fields does not come through. The field labels are there as indicated below and the email is formatted correctly, but the data doesn't come through.
mail( $to = "[email protected]", $subject = "Someone has submitted an application",
$content= "Essay 1: ".$Essay1."\r\n"
."Essay 2: ".$Essay2."\r\n"
."Essay 3: ".$Essay3."\r\n"
."Essay 4: ".$Essay4."\r\n"
."Essay 5: ".$Essay5."\r\n");
What am I doing wrong?
That's problem #1 - then problem #2 is that I actually also need to send the ID code in this email for the specific record which has been created in my database so the end recipient can associate the email with that specific ID later for other purposes. So even if I figure out problem #1, I'm not sure that I can use this code for problem #2 because the field isn't on the html form, but actually created by the database upon submission.
Any suggestions would be helpful!
Thanks

MySql database Connection failure

Hi,
I have following code. I am using MySql database. and Tomcat server and MySql jdbc driver. I am able to get the Datasource but when I call getConnection on ds, I get Connection object as null. Any help here?

CS3 mysql database connection using php

Hi, this is my first time trying to connect to a database. I have created a mysql database with my hosting provider. I am also configured to use php. I have ready numerous threads on this topic, but am still confused.
I am getting the following error message:
When I enter the following information into the connection string, I get the following error Error http error code 404 file not found. The site does not map to ftp.readyhosting.com/_mmserverscripts/mmhttdb.php Is the location of mysql server correct? Connection name ? user defined ?aosprod?
Mysql server = aoswebeditor.readyhostingmysql.com. Also, this is not the same location as the web server.
The hosting company provides the following php code to connect to the database.
<?php
$link = mysql_connect('aoswebeditor.readyhostingmysql.com', 'aosweb', '*password*');
if (!$link) {
die('Could not connect: ' . mysql_error());
echo 'Connected successfully';
mysql_select_db(aos);
?>
Because of the connection dialog boxes in CS3, I have not used this php code but only used the mysql server aoswebeditor.readyhostingmysql.com.
My requirements are very simple, I want to use the same remote database for the dreamweaver connection for the remote and testing server.
Any ideas would be appreciated.
Thanks. George

First of all, you seem to be mixed up about terminology. ASP stands for Active Server Pages, and is a type of server technology similar to PHP. I think you mean ISP (Internet Service Provider). However, this is not correct, either. An ISP provides your connection to the internet. Although some ISPs also host websites for their customers, your website is normally located at a hosting company. You need to get that mixup out of the way. Otherwise, you might confuse people with future questions about ASP, when you actually mean something completely different.
OK, lecture over...
Your hosting company is following standard procedure by preventing remote access to MySQL databases. However, Dreamweaver does make it possible to use your remote database and website for testing purposes. It does so by uploading a hidden folder called _mmServerScripts to your remote server. This performs a local connection with your database, and then sends the results back to your local computer. When setting up your testing server definition in Dreamweaver, you need to provide the details as I indicated before. When creating a MySQL connection in Dreamweaver, fill in the server name and account details as given to you by your hosting company. If everything is set up correctly, you should be able to use your remote server and database for testing.
Having said that, it is much better to install a local testing environment. You'll find it faster, and it also lets you make mistakes (an essential part of the learning process) in the security of a closed environment. For details of how to set up a local testing environment, see this article in the Adobe Developer Connection.

JSP, EJB in Jboss 4 with mySQL database. Error in connecting to database

Hi, i using JBoss 4-0-1 with jsp and mySQL database. I get this example from a book using stateless session beans. However i modify it so it can connect to mySQL database.
This is my code for jsp.
<%@ page import="asg.MusicEJB.*,
java.util.*,
javax.naming.Context,
javax.naming.InitialContext,
javax.rmi.PortableRemoteObject" errorPage="error.jsp" %>
<%--
     The following 3 variables appear in a JSP declaration.
     They appear outside the generated _jspService() method,
     which gives them class scope.
     Since we want to initialize our Music EJB object once
     and read the Music Collection database to get the
     recording titles once, we place this code inside
     method jspInit().
     The EJB business method getMusicList()
     returns a collection of RecordingVO objects which we
     store in ArrayList albums.
--%>
<%!
     MusicHome musicHome;
     Music mymusic;
     ArrayList albums;
     Properties properties=new Properties();
     public void jspInit() {
               properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
               properties.put(Context.PROVIDER_URL, "localhost:3306");
               System.out.println("............................in properties");
          try {
               //Context initial = new InitialContext();
               InitialContext jndiContext = new InitialContext(properties);
               //Object ref = jndiContext.lookup("MusicEJB");
               Object objref = jndiContext.lookup("java:comp/env/ejb/EJBMusic");
               musicHome = (MusicHome)PortableRemoteObject.narrow(objref, MusicHome.class);
               mymusic = musicHome.create();
               albums = mymusic.getMusicList();
               System.out.println(".............................in line 64");
          } catch (Exception ex) {
               System.out.println("Unexpected Exception............: " +
                         ex.getMessage());
               ex.printStackTrace();
%>
<%--
     The following scriptlet accesses the implicit
     request object to obtain the current URL
     and saves it to the session object for later retrieval.
     It also saves variable mymusic, so we can
     make remote calls to our Music EJB, and the collection of
     RecordingVO objects. These variables will all be available
     to other pages within the session.
--%>
<%
     String requestURI = request.getRequestURI();
     session.putValue("url", requestURI);
     session.putValue("mymusic", mymusic);
     session.putValue("albums", albums);

here i'm trying to connect to Users mysql database (i use Tomcat 4.1 and mysql servers and clients 4.0.1-alpha)
where is the problem ? when i run this servlet (http://localhost:8080/example/servlet/LoginServletJDBC ) it works ;
BUT when i type an username and a password (any user&pass) my servlet doesn't connect to the database (become a infinite loop without output ; i mean no any errors and exceptions)
i try other think : i changed the database with unexisting database and the result was that i was expected (Unknow database 'unexistingdatabase' )
what i miss ?
please... can anyone help me...
thank`s in advance

The wireless security setting that the Actiontec modem/router is using may be different...and not compatible....than the setting that the Comcast product was using.
If you think that might the case, and you have the time to troubleshoot......
Temporarily, turn off the wireless security on the Actiontec modem/router
Reset an AirPort Express back to default settings, then see if it will connect using no security and allow an Internet connection when you do the Ethernet port test in the post above again.
If the AirPort Express cannot connect correctly using no security on the wireless network.....then it is a no brainer to know that it will never connect when security is enabled. So, if the AirPort will not connect using no security, you may have an incompatibility issue between the Actiontec and Apple products.
However, if the AirPort Express connects OK with no security, then this tells you that you will need to use a different setting for security on the Actiontec...the same that the Comcast router was using before.....so the Express will have a better chance of connecting.
That setting would be something like WPA/WPA2 Personal, or the same setting stated another way would be WPA-PSK-TKIP.

Problem with inserting data into mySQL database with jsp

I have a jsp page that collects infromation about a users vehicle and puts the data into a mySQL database. Iv'e been messing around with it for ages & i can't seem to get it to work even though i cannot see anything wrong with the code, which can be seen below.

Any help would be much appreciated.

use this ...
PreparedStatement vehicle_details =
Connvehicle_details.prepareStatement("INSERT INTO
vehicle_man_db.vehicle_details (registartion, make,
model, colour, tax_class, chasis_num) VALUES
vehicle_details .setString(1,String
vehicle_details__registration );
vehicle_details setString(2,String
vehicle_details__make );
vehicle_details .setString(3,String
vehicle_details__model );
vehicle_details .setString(4,vehicle_details__colour
vehicle_details .setString(5,String
vehicle_details__tax_class);
vehicle_details .setString(6,String
vehicle_details__chasis_num );
vehicle_details .executeQuery();Even you need a screwing up... what's the point putting that String inside. That's the bloody error.
