How do I connect to a mysql database?
I am trying to write a small program with Java to do some operation on a Mysql database. The first step is to connect to the database. Can anybody give me some information about how to connect to it with JDBC? Thank you in advance!
// SQL jdbc driver
String SQLDriver = "com.mysql.jdbc.Driver";
// SQL connection string
String SQLConnectionString = "jdbc:mysql://localhost/passport?user=root&password=your_MYSQL_Password";
// Load database driver
Class.forName(connectionDriver);
// Make connection
Connection sqlconn = DriverManager.getConnection(connectionString);rykk

How to connect to a MySQL database in another server
Dear friends,
I am using Oracle SQL Developer 1.5.3 and I need to connect to a MySQL database located in another server.
I am trying to create a new connection, informing connection name, username and password. Supposing that "Hostname" is the IP server address, I click on "Choose database", but I always receive the following error message: "Status : Failure - Cannot connect to MySQL server".
Please tell me what I should do to solve this situation. Thanks in advance.
Best regards,
FranklinYou need to configure your mysql database to accept connection from your PC for the user you used.
For example,
GRANT ALL ON *.* TO 'someuser'@'somehost';

How to get the data from mysql database which is being accessed by a PHP application and process the data locally in adobe air application and finally commit the changes back in to mysql database through the PHP application.
If the data is on a remote server (for example, PHP running on a web server, talking to a MySQL server) then you do this in an AIR application the same way you would do it with any Flex application (or ajax application, if you're building your AIR app in HTML/JS).
That's a broad answer, but in fact there are lots of ways to communicate between Flex and PHP. The most common and best in most cases is to use AMFPHP (http://amfphp.org/) or the new ZEND AMF support in the Zend Framework.
This page is a good starting point for learning about Flex and PHP communication:
http://www.adobe.com/devnet/flex/flex_php.html
Also, in Flash Builder 4 they've added a lot of remote-data-connection functionality, including a lot that's designed for PHP. Take a look at the Flash Builder 4 public beta for more on that: http://labs.adobe.com/technologies/flashbuilder4/ -
Connect to a mysql database with Oracle 9i
Hello,
how can I connect to a non_oracle-database in "Oracle 9i".
I created a ODBC data source. In Oracle8 I needed OCA. But in 9i I believe the OCA is replaced by another thing.
I wanted to connect in SQL*PLUS with:
username/password@odbc:mysql
But I get the error: ora-03121 "no interface driver connected - function not performed".
How can I connect to another database?I've solved the DW problem by changing the site folders from
'db' to 'wwwroot' e.g. 'C:\CFusionMX\db\' is now
'C:\CFusionMX\wwwroot\
However I'm now back to my original problem. I've lost my
mqysql connection in CF Adminstrator. Before I made these changes I
could connect to my mysql databases using the following settings:
JDBC URL: jdbc:mysql://localhost:3306/test
Driver Name: MySQL Connector J
using the following Java path and file:
C:\CFusionMX\wwwroot\WEB-INF\lib\mysql-connector-java-3.0.17-ga-bin.jar
Now these settings give me the following error:
"Connection verification failed for data source: javaserver
[]java.sql.SQLException: SQLException occurred in JDBCPool
while attempting to connect, please check your username, password,
URL, and other connectivity info.
The root cause was that: java.sql.SQLException: SQLException
occurred in JDBCPool while attempting to connect, please check your
username, password, URL, and other connectivity info"
Any suggestions on this would also be welcome.
Thanks again to everyone for their help.

Connecting to a Mysql database using CF Administrator and DW
I can't create a mysql datasource in CF Administrator.
If I use the following datasource settings in CF
Administrator:
JDBC URL: jdbc:mysql://localhost:3306/test
Drive Class: MySQL Connector J
AND (note the emphasis) I set my local and remote folders in
my DW site local folder, remote folder and testing server folders
all to C:\CFusionMX\db\, I can connect to my mysql database in CF
Administrator.
However, with these DW site folder settings, DW doesn't
recognize any databases (Access or Mysql) at all.
When I change my DW site folder settings to 'wwwroot'
(e.g.local folder C:\CFusionMX\db\' is changed to
'C:\CFusionMX\wwwroot') DW now lists all my CF Administrator
databases.
The problem is CF Administrator can't connect to my Mysql
data sources. It gives me the error:
"Connection verification failed for data source: javaserver

while attempting to connect, please check your username, password,
URL, and other connectivity info.

I've tried changing the 3306 port to 8500, but this doesn't
help.
My java path and connector file is:
C:\CFusionMX\wwwroot\WEB-INF\lib\mysql-connector-java-3.0.17-ga-bin.jar,
Is this a ID/password problem? I've tried both 'root' and
leaving the ID field in the CF Administrator add data source block,
both to no avail. I don't have a password set in Mysql for 'root'
either.
Any help would be gratefully appreciated. I've been working
on this for weeks and keep running into one problem after another.
Thanks a million in advance.

Graham A. Kerby1) ensure mysql server is running
2) there are numerous tutorials for mysql installation out
there
3) there are good free mysql admin tools out there
4) use both the above to verify your mysql installation is
correct
5) please tell me you do have your zonealarm DISABLED

PHP Connection to a MySQL database "An unidentified err has occurred"
This is driving me up the wall.... With my hosting provider
at work I cannot make a connection to a MySQL database with
dreamweaver using the new connection in the databases tab. "an
unidentified error has occurred"
I am certain that I am entering the info correctly and have
the correct permissions to access the database, I think it has to
do with the _mmServerScripts folder and the testing server.
With the hosting provider that I use for personal websites I
make connections all day long doing the exact same thing that I am
doing here at work and I'm stumped. I even read a lenghty article
on this forum with possible solutions... none of them worked.
Is there any way around the _mmServerScripts directory and
testing server to make a connection and then use the bindings and
server behaviors tabs to creat recordsets, etc??
Thanks in advance for any help!

Not if you want to use Dreamweaver server behaviors, no. The
usual
meaning of "an unidentified error has occurred" is failure to
connect
because communication is blocked by a firewall.

Can APEX/ORACLE connect to a mysql database?
Hi
Just wondered whether APEX and ORACLE could connect to mysql database. I may have a requirement to link to a mysql database and retrieve the data and wondered if APEX could do this.
ThanksHi
Apex sits within the Oracle database. Oracle can connect to a mysql database via a database link so yes this is certainly possible. We connect extensively to an Informix database here actually. This is really an oracle question though so you just need to look in the documentation for the CREATE DATABASE LINK command and for setting up the actual connection.
If you need more help let me know.
Cheers

How can I connect to a different database schema,other than adobe?
I'm building an application where I want to use a different database for it,for storing additional data for the users(different from "edcprincipaluserentity" table in "adobe" database stores)..How I can connect to my database schema created in MySQL from Workbench,to assign tasks to my users,using the Process Management/Assign Task service?
You can only assign task to user that are known by the LiveCycle User Manager.
When you configure LiveCycle, you can tell it where you want to get the users from. They can be created them locally in the local database, or synchronized from an LDAP directory in which case it'll read the users from LDAP and make a copy of some of the properties to the internal LiveCycle database.
Bottom line, all users have an id (in the edcprincipalentity table) in the adobe database.
If you need your users to come from a different database, then you need to customize the SPI (security provider interface) so that you can synchronize the users coming from your external database. Again, this is a customization since out of the box, we don't synchronize against external database. But it is possible, the API is there and other customers have done it.
I hope this clarifies things a bit.

Phpmyadmin connection issue with mysql database on local computer
Got mysql and phpmyadmin installed on my iMac. I open phpmyadmin site in safari and try to login to the database and I get the following error:
"Safari can’t open the page “http://imac.local/phpMyAdmin/index.php?lang=en-utf-8&token=872752b265e4d375dddae b18d06bd85b” because the server unexpectedly dropped the connection, which sometimes occurs when the server is busy. You might be able to open the page later."
I can connect to the sql database okay from the mysql manager gui just fine. Any suggestions?Hi David-
Thank you for your QUICK and CORRECT reply! Yes, creating the _mmServerScripts folder in my SSL folder on my remote server did the trick!!
I did try to setup a testing server using one of your tutorials, but I received FTP errors. Since I have a working website with remote and testing flagged on the same server and for my ease of understanding, I copied the setup as closely as I could (less the SSL add-on). Mind you, I originally setup that website 3 years ago, so I'm a bit rusty. I'm not a web developer and don't do this for a living, thus I get by with instructions from the books I own, web tutorials, Adobe forums, etc., but I have not taken any classes. It's not my choice to work with PHP, but I have to in order to pull data from database tables into my web pages. Since I don't do this for paying customers, I don't have to setup anything too fancy (thank goodness). I would like to know how to debug and write java script code, but I lack the time and patience (mostly patience).
Besides...Adobe does such a good job with their products, that I can get by pretty well without having to know everything.
Again, THANK YOU!!!
PS- Would you mind replacing my root site info above with the following: www.sitename.com/ssl/ -

Thanks,Hi Andrew,
check out this <a href="http://developers.sun.com/product/jdbc/drivers">site</a>, maybe you find a suitable driver there? The SAP Press and Helpfiles say, that connecting to a microsoft SQL Database is possible.
In our portal I found a MSsql jdbc driver installed, with sucessful connection test to northwind-database. Unfortunately, I cannot find out what driver we used.
If you still don't find a driver, I will ask my colleague if he remembers.
Best Regards, Benni

Problem creating connection pool to mysql database
Please, do not ignore this message and help me, if you have any Idea
I have Sun Java System Application Server 8.1 installed on my computer, I installed also MySQL Connector/J to access MySql Databases through JDBC
But now when I try to create new connection pool, an error comes:
Following parameter were used:
Name: MYSQL1
Resource Type: javax.sql.XADataSource
Database Vendor: mysql
Datasource Classname: com.mysql.jdbc.Driver
serverName 192.168.0.152

databaseName test
datasourceName
After saving and then klicking on Ping button, following error comes: "An error has occurred.
Operation 'pingConnectionPool' failed in 'resources' Config Mbean. Target exception message: com.mysql.jdbc.Driver"
I checked the logs of MySql, there was no attempt to access given Database or MYSQL-server at all
What Am I doing wrong? How can I create MySql connection under Sun Java System Application Server 8.1?
Any help will be appreciatedThe driver is in right place
Originally I placed him in wrong directory and got an error, indicationg, that Driver class is not found, but then I corrected it, The problem is in connection to database - it doesn't work.
I tired to load the same driver into Netbeans and could easyli create a connection to database, but I get it not working ander Sun Application server -
How to get data into the mySQL database?
First some background.
I have a website that has outgrown its designed dimensions and is a huge burden to maintain. See PPBM5 Benchmark
There is a lot of maintenance work involved, so I'm investigating a PHP/MySQL approach to easen the burden and to add functionality to the site. With the current Excel based structure and over 420 entries, it is cumbersome for me to maintain, but also for users to find what they need.
A MySQL based dynamic structure is a lot easier and offers vastly more selection capabilities, like selecting only records that meet specific criteria.
Data submission is done with a form, that contains most of the relevant data, but the drawack is that people submitting their data are often not technically inclined, give wrong answers due to a lack of understanding or making typo's. The test results are attached in one or two separate .txt files, but often they have not read the instructions correctly or did something wrong, so these attached .txt files can not be trusted automatically, they have to be checked before inclusion.
These were my initial thoughts:
1. Data collection:
To avoid spending all our energy and time on correcting typo's, getting missing data, correcting errors, I am investigating the use of CPU-Z in Ghost mode to create a .txt or .html file that contains all relevant hardware info we need and even more. It gives all the info we currently have, but adds data like number of memory sticks, DDR timings, stock clock speed and BCLK setting, video card info and VRAM size, etc.
To see what I mean, run CPU-Z, go to the About tab and press the Save Report button and look at the results.
This can all be done without user intervention in an automatic way, but maybe I need to add an Auto-It file to the test to make it all run as desired.
If this works and I'm able to extract the relevant data from the created file and can insert it into the database, we may be in business for the next version of PPBM5.5 or PPBM6. It does require a modification to the instructions, making them a lot easier, because there is less data to fill out.
2. Data submission:
The submission form can be simplified if the CPU-Z data can be used. We have to create an automatic way to attach the created .html file from CPU-Z to the submission form and we have to streamline the Output.txt and Output-MPE.txt files to be more easily included in the 'form.lib.php' file. It currently is manual labor and very time consuming.
3. Adding to Database:
I have to find a way to create database records from the Gmail forms I receive. All incoming mail messages need to be checked on relevancy and if relevant, need to be added automatically to the database and then offered for approval before final inclusion in the database. Data included in the database will then include submission date and time, Email address, IP address used, plus links to the files submitted and available on the website.
4. Publication of the database:
After approval of new records from step 3, all updates will be automatically applied to the database and accessible for users. I do not yet intend to introduce a user account , requesting login before all functionality is accessible. Too much trouble and administration.
Queries should be possible on things like CPU (check box), so include 17-920, i7-930, i7-950 but exclude i7-980X and i7-990X, Size of memory (check box), Overclocked (boolean, yes, no), SSD as OS disk, and similar options.
The biggest problem is to keep the color grading and statistical indicators (Top, D9, Q3, Med, Q1 and D1) intact on dynamically generated queries. Say you make a query which results in 20 observations, this should show the related colors and legends. Next query results in 48 observations and of course the color grading and legends do need to reflect that. Question in my mind, does the RPI remain constant, independent of the query or does that need to be recalculated on the basis of the query?
Next thing is to allow a user to select a specific observation and by simply clicking on it be shown, in a separate window (detail page) or accordion, all the CPU-Z related information about the hardware.
The graphs, Top-20 and MPE Gains, need to be dynamically adjusted, based on the query used.
5. Ideally, external links:
In an ideal situation, one could link the CPU-Z data to external price databases, looking up current prices for CPU, memory, video card, disks, raid controller, etc. to get instant BFTB charts, based on the query made. But that is the next step.
Situation now:
I have a MySQL database that is easily updated with the new submissions. Simply create a .CSV flie from the submitted forms and import that into the database. The bulk of the initial work is done.Lots remain to be done as you can see above, but that is for a later time.
Question:
I have this table, that needs to be filled with data in the submitted and attached files. Mr. X submitted his data and can be uniquely identified by his "Ref_ID". He attached one or two files in .TXT format with the relevant test data. These files are stored on the server with a concatenated name:
"Ref_ID","-","filename"
Say his Ref-ID is: 20110204-6cf5 and his submitted file is called: Output(99).txt then the file can be found on the server as
20110204-6cf5-Output(99).txt
I need to be able to open that comma delimited file, the contents may look like this: "439","1036","819","531" and insert these contents into the relevant record and fields.
Graphically,
is what I want to achieve.
This being my first exposure to PHP/MySQL, you can imagine I'm not clear on how to go from here.
Added complication is that I actually have 5 numbers to insert per record and two calculated fields, Total Score and RPI should be calculated fields. Haven't yet figured out how to handle calculated fields, maybe only in the PHP/HTML code and not in the database.
I hope someone can help me.You do have a very complex looking site and may need several tables in mysql to handle all that data. If you knew to phpmysql I would suggest taking a look at this tutorial it will help get you started in understanding how to $_GET info from a database and also how to $_POST data to a database. I am no expert just learning myself and I found this very helpful. This is the link http://www.adobe.com/devnet/dreamweaver/articles/first_dynamic_site_pt1.html
There are also many tutorials on Youtube to help build a CMS Content Management Site I would suggest the following: -

And many more on my channel here
