Problem in mysql connectivity

Hi friends
i have connect the java program using mySQL. Every thing is going fine, but when i use
rs.moveToInsertRow()
rs.updateString()
rs.insertRow()
there is a exception occurs.
I have created the Statement Object using
ResultSet.TYPE_SCROLL_INSENSITIVE
ResultSet.CONCUR_UPDATABLE
Plz Help me
Thanx

You didn't share the exception information with us so really it's hard to tell. There could be a large number of things wrong, for example you could be failing to provide a value for a column that cannot be null.
As a guess though I would say that you should be aware that asking for an updatable cursor is a request not a command. You are requesting an updatable cursor and the database/driver MAY return an updatable cursor or it MAY NOT. There are some DB/driver dependent factors as to whether a cursor will be updatable or not. These factors include thiings like often you must select the primary key as part of the result set, that you most often can't use JOINs, other factors may apply. Anyway look into that.

PHP and MySQL Connection problem

I am trying to make a PHP MySQL on a remote server connection in Dreamwesaver CS3.
When I enter the information (host, user, password, etc.) and hit TEST, I get the following error message.
"Access Denied. The file may not exist, or there could be a permission problem. Make sure you have proper authorization on the server and the server is properly configured."
I know the user, password, etc. work, as I can access the MySQL database with other software.
I checked with my host and they say there are no permission problems on their end.
I have checked the settings on the Test Server page in Site Setup and everything looks correct and works there.
I have not seen this particular problem described in other forum postings (although there are a LOT of postings on this topic!).
Any help would be appreciated.

I thought my testing server was the remote server and is always on as far as I know. I don't know how to turn it on or off.
Is there some other testing server that I should be aware of?

Subject: PHP and MySQL Connection problem
I know you are using remote, but is your testing server on? if not turn that on and see if that does it. it just happened to me working on remote server and could not get mysql conn to work, until I turn on my testing (developer server), then I was able to connect to mysql and the tables that I created in phpmyadmin remotly was downloaded.

Problem in establishing connection with mysql 5.0

Hi,
I am using JCAPS 5.1. I tried to insert data to mysql database table.
But i got following error
java.sql.SQLException: Error in allocating a connection. Cause:
Physical Connection doesn't exist.
My intention is to read file in which data are comma seperated and to
populate those values to a mysql 5.0 database table.
Sample DATA in file [test.txt]
111,gg,23,MFG
112,hh,24,MFG
113,ii,25,RETAIL
114,jj,26,IT
Database table: employee
eno,ename,eage,edept
While creating JDBC OTD there is no problem in establishing connection with database. But after deploying i got above error.
I have used Mysql 5.0 Connector/J JDBC driver. Added JDBC driver jar files to following directories as required.
1) C:\JavaCAPS51\logicalhost\is\lib
2)C:\JavaCAPS51\logicalhost\is\domains\test\lib
Steps i have followed as per JDBC-ODBC -eway user guide doc.
1) Created USerDefined OTD and added necessary fields
2) Created JDBC OTD.
3) Created JAVA collaboration and do business process for inserting
4) Mapped all components by creating in Connectivity MAp
5) created necessary external systems in envrionment explorer.[JDBC External System and File External System]
6)Created Deployment profile
5) Deployed it.
After deploying it gives error as
java.sql.SQLException: Error in allocating a connection. Cause: Physical Connection doesn't exist
Please let me know the solution for problem.

In the environment definition,
-> External Application JDBC
-> Properties
-> Outbound JDBC Connection
You have the database URL in the "DriverProperties" field
Valid URL would be : jdbc:mysql://localhost:3306/caps
!! The doc says that this field is optional !! Seems to be an error in the doc:
Hope this helps

You can try with this code coz, i worked with this code only and then i can talk to the database.
Connection con;
Class.forName("org.gjt.mm.mysql.Driver";
con = DriverManager.getConnection("jdbc:mysql:///db?user=root&password=");
Try it out!

Problem of remote connection on MySql Server from Mac OSX

Hi everyone,
I have a flash application that work on both plateforms Pc and Mac. In this application i do a connection to a MySqlDatabase to activate it.
so, to make my tests i have a pc and mac on the same home network
to make sure it works fine, i have installed EasyPhp on my PC and MAMP on the Mac, to be able to test the connection to local MySqlServer.
the syntaxe that i use to connect to the database is this one :
mdm.Database.MySQL.connect(host:String, port:String, compression:Boolean, userName:String, password:String, databaseName:String)
So, to connect to local MySqlServer : i have this code:
mdm.Database.MySQL.connect("localhost", "3306", true, "root", "", "DBName");
and it work just fine on the PC using EasyPhp and on the Mac using MAMP. I can connect on my database on each plateform.
So now, i want to connect to our remote MySqlServer, so, to connect to our Private server : i have this code:
mdm.Database.MySQL.connect("64.150.160.230", "3306", true, "userName", "userPassword", "DBName");
on the PC: it works just fine, i am able to connect to our database and do queries on our private server.
on the Mac : it cannot connect... errore message: unable to connect to server
I really don't know where it is coming from.
I would like to test a connexion to my remote MySqlDatabase, by sinf just the terminal. Does anyone know the syntaxe to use to connect to a remote MySqlDatabase using the Terminal?
It can be a blocked port on my Mac, because i am able to connect with this port on my local MySql Server...
Any help will be welcome.
Best regards.

No Tables in DW CS3 Remote MySQL Connection

Hello All,
I was hoping forum members would be able to troubleshoot a
Dreamweaver CS3/remote MySQL Connection issue I'm having.
I am successful in connecting to the database but the table
data I created in phpMyAdmin 2.6.3 does not appear in the
Application/Databases menu in DW. Instead of the name of the table,
I get "none".
Since I am new to databases, any help is greatly appreciated.
I did view older posts before submitting this one but the advice
recommended (re-installing the entire MySQL application from
scratch) is not an option. Server is SunOS running PHP 4.4.7 and
MySQL 2.0.20. I'm on Windows XP. Thanks once again.

Was this issue resolved?
I have the same problem now. DW was working fine the one day and the next when I started it it had this connection problem.
I am testing on my local PC. My sites is at http://localhost/
All my connection are working because if I go to http://localhost/index.php I can see my site and if I go to http://localhost/register.php I can even register a new user. It will include the new user details in the data base and everything is working fine. So there is nothing wrong with the connection.
In DW I do have http://localhost/ on the Local Info screen. As I said, all was working fine on the current setup the one day and the next day it did not want to work.
Seems like a very common problem.
I want to buy CS4 and surely hope that the problem has been fixed by now.

Cannot connect from dreamweaver cs5.5 to mysql using the mysql connection wizard

Cannot connect from dreamweaver cs5.5 to mysql using the mysql connection wizard error Http error 403 or 500 internal server error. I am using ubuntu mysql.
a manual php script work fine
<?php
// open connection to mysql server
$dbc = mysql_connect('localhost','root','password');
if (!$dbc) {
die('Not Connected' . mysql_error ());
//select database
$db_selected = mysql_select_db ("msinventory",$dbc);
if (!$db_selected)
die('Cannot Connect' . mysql_error());
echo "TEST DONE1";
?>
but the database connection wizard fails with http error 403 or 500
i also use the HeidiSQL client and it works, the only problem is in dreamweaver.

OK. Did you really mean to ask this question on a ColdFusion forum, if it's DreamWeaver you're having problems with? You're probably better off raising this on a DreamWeaver forum. "Using the correct tool for the job" 'n'all.

MySQL Connection Issue

Hi -
I've been having a problem where my connection to MySQL gets closed out from under me after about 5 mins of inactivity. I'm using Toplink to manage the connection pool, but I can see via netstat that the initial connections all get closed after about 5 mins of inactivity.
I've looked at the "normal" MySQL timeout settings and everything looks fine.
Any ideas?
Thanks,
Frank

TopLink does not timeout connections. So this is occurring somewhere else. Typically in your firewall.
<p>
If you can't avoid the reset you could configure an ExceptionHandler in TopLink to reconnect the dead connections. TopLink 11g will handle dead connections automatically, so you could upgrade to this release (preview), or upgrade to EclipseLink (I'm not sure if the support is in the latest 11g preview, but it is in EclipseLink). You could also use a third party connection pool or DataSource that supports handling dead connections.
<p>

PHP MySql connection to GoDaddy

I use DWCS4, PHP, MySQL. I have created a MySql database on my GoDaddy-hosted account and can FTP to it and have transferred tables and data to it. However, when I try to create a database connection in DW, I get the following error message; "Your PHP server does not have the MySQL module loaded or you can’t use the mysql_(p)connect functions."
I searched for solutions on the web (no answers in this forum), and got several results that said to manually create the connection file such as the following
<?php//Sample Database Connection Syntax for PHP and MySQL.
//Connect To Database
$hostname="your_mysqlserver.secureserver.net";
$username="your_dbusername";
$password="your_dbpassword";
$dbname="your_dbusername";
$usertable="your_tablename";
$yourfield = "your_field";
mysql_connect($hostname,$username, $password) OR DIE ("<html><script language='JavaScript'>
alert('Unable to connect to database! Please try again later.');
history.go(-1);</script></html>");
mysql_select_db($dbname);
?>
Just fill in your password etc, save it as connectdb.php (or whatever), and include it at the top of the files that need to access the database. You could use an if statement to determine whether you were working locally or on GoDaddy.
I tried that, but it still won't connect. (My regular connection for just transferring files works fine).
Has anyone out there solved the GoDaddy database connection problem?
Frank

Check php_info()to see which connector is enabled.
It should be either mysql or mysqli.
Since you are having problems with mysql, try to connect with mysqli connector.
If that won't solve your problem, email GD about your problem, and ask if any mysql connectors are enabled in your hosting plan.

Few question about Java and MySQL connection

Hi!
I have some problems with creating connection between Java and MySQL.
I followed the restrictions in mysql-connector-java.jar' readme, I set the CLASSPATH :
CLASSPATH=.;D:/mysql/mysql-connector-java.jar;
I copied this jar file to the right place (descripted above), and I used the right steps to load it:
Class.forName('com.mysql.jdbc.Driver"); and it throws a ClassNotFoundException
Why? All the paths are correct, everything is on the right place.... I dont know why.
When I installed the JBuilder8, and copied the jar file to JBuilder8/jdk4/jre/lib/ext it worked without any CLASSPATH in enviromental variables.
If I want to run my program on machines where are not JBuilder, what should I do?
Please help, if you can.
Thanks,
henpanta

Yeah. So if I compiled my program with JBuilder to an .exe file, I cant run it on other machines, if the jar file isnt in the same place?
If I tried your advice, java -classpath mymainclass I got the next message:
main class not found. Believe me, its there. :(

What's wrong with this MySQL connection? "Could not create connection to database server"

I'm able to connect to other MySQL databases but this one particular remote MySQL connection isn't working and I cannot figure it out. It probably has something to do with the remote server, not CF, but I thought I'd post it here if anyone had an idea. The MySQL account has full priviledges.
Here is the message when I try to validate the data source:
Connection verification failed for data source: test
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.
The root cause was that: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.

This happened on two servers. One one, the cause was that skip-networking was turned on. In the other situation, it appears that the database name was case sensitive, so TEST was not the same as test. Even though I edited the data source in the CF administrator, it still didn't work (very misleading). When a coworker entered a new data source with the same information (uppercase database name this time from the start), it worked.
Has anyone else seen this problem with the case sensitive database names? And with the data source in CF not updating the case correctly? Seems like a bug in CF.

MySQL Connection - Select Database - HTTP Error Code 405 Method Not Allowed?

We've set up a MySQL database with our host and can connect to that, and create, edit, delete tables using HeidiSQL, without a problem.
However when we attempt to set up the connection in the Databases tab of our Applications panel in Dreamweaver we receive the following error:
HTTP Error Code 405 Method Not Allowed
We have entered the following in the MySQL Connection box:
Name: <name of our connection>
Server: <IP address of our database>
Username: <our database username>
Password: <our database password>
Database:
When we click the "Select" option next to the Database field, that's when we receive the above mentioned error.
We noticed that there was a fix posted by Adobe at:
http://www.macromedia.com/support/dreamweaver/ts/documents/err405.htm
...but that link is long since dead, however it does seem to indicate that Adobe are/were aware of this issue.
Can anyone help? We're trying to move from Classic ASP / MSSQL to PHP / MySQL but have hit a barrier right from the off, which isn't very encouraging. Hope someone can ease our concerns with PHP and MySQL.
Much appreciated.
NJ

Thank you SnakEyez02.
I had the Testing Server set to Local/Network but didn't have MySQL installed locally. Changed that setting to FTP and it picked up on the database correctly.
When using MSSQL it doesn't matter whether you choose Local/Network or FTP it just picks up the online database regardless. I guess this must just be a difference between it and MySQL.
Thanks for the advice. Much appreciated.
