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,
    Franklin

    You 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';
    FLUSH PRIVILEGES;

    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

    However I'm now back to my original problem. I've lost my

    could connect to my mysql databases using the following settings:
    JDBC URL: jdbc:mysql://localhost:3306/test

    using the following Java path and file:
    C:\CFusionMX\wwwroot\WEB-INF\lib\mysql-connector-java-3.0.17-ga-bin.jar

  • 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.
    Thanks

    Hi
    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.

  • 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/

    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

  • 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: -

    http://www.youtube.com/user/betterphp
    http://www.youtube.com/user/flashbuilding
    And many more on my channel here
    http://www.youtube.com/user/Whisperingonthewind
    CMS's are easier to maintain, add edit and delete content.
    I have also recently bought a Book by David Powers Training from the Source very helpful.
    Anyway hope you get it sorted.
