What can I actually to with database connections?

This may sound like an odd question, but once I define a MySQL connection in Dreamweaver, what can I actually do with it? Let me clarify what I'm doing:
I've only just found out that we can define MySQL connections when a PHP/MySQL site is defined. I'm used to administering my databases via MySequel or phpMyAdmin. Accessing databases in Dreamweaver would rock!
So now I've got a connection, I can read all my tables... but I can't seem to do anything with them. I can't add data, I can't modify data - all I can do is look at what's already there. I can click the "insert code" or the "view data" option, but they don't seem to do anything useful: The first option only pastes whatever is highlighted in my code, and the second brings up a window displaying the data.
What am I missing? Can I change the data somehow and just haven't found the option yet? Or what else can I use my database for?
For example, exporting or importing data, synchronising with another database/database host, etc?

Database connections are used to develop data driven web sites. So if you are familiar with server side scripting you can write code to make your site dynamic. In the past, DW had server behaviors that streamlined the process of creating web forms and display areas to insert, update and select from database tables, but these have been removed as the code was never quite up to current standards.

  • What can I actually do with the Apple TV2 in the UK?

    Sounds like a silly question, but im quite serious!
    I know that the services differ from country to country, but im just wondering what the apple TV can do by its self.
    I'm guessing that we CANT watch NetFlix as they havent launched in the UK?
    We CAN watch Youtube and Vimo?
    Can we stream content directly from Apples servers (ie, if I rent a movie, do I have to download it onto my mac first?)
    what about TV shows?
    Again, sorry for sounding a little silly, but I just want to know
    Thanks for all your help

    Hi Neil.
    Winston, Chenks and I are all from UK and have used AppleTVs for many years - I always found it strange that UK posters were more prolific than US posters here, but I think that may have been down to better availability of streaming services in US generally until recently compared to UK and AppleTv may have had a niche market here - may be wrong.
    AppleTv1 was originally an 'iTunes extender' for compatible media (see specs).
    You could sync media from iTunes to it to play with computer off or stream additional media from itunes when computer was on.
    Later SD/HD Rentals and TV/Movie/Music/Music Video purchases came to AppleTV1, syncing back to iTunes.
    It allowed access to mobileMe, Flickr, youtube media, podcasts and internet radio.
    AppleTV 1 had some benefits over 2 but was also underpowered hardware wise compared to the newer unit (which some would argue is still the case due to lack of 1080p support).
    AppleTV2 has been repositioned less as a vehicle to play itunes content, but more of an online rental device, with some internet services supported and in my view a strong emphasis as an accessory for iPhones/iPad/iPod tocuhes using Airplay.
    You can still play compatible content from iTunes (again see specs on Apple's pages).
    Netflix not available in UK but apparently Netflix coming in next 12 months - no idea if AppleTV will support.
    There are some premium subscription  US sports intrenet feeds - personally I have no interest, some are US only, some are worldwide with a valid subscription.
    YouTube still available, Vimeo, Flickr and MobileMe remain as do Apple's Radio Stations and Podcasts.
    US had Movie and Tv Rentals we only had Movie rentals.  US dropped the TV Rentals.
    US it seems can purchase content not just rent.  We can't currently in UK outside of iTunes.
    Airplay from an iDevice (newer models on the whole) will allow apps enabled for Airplay to stream the display to AppleTV.  iPad2 and iPhone 4S also support video mirroring on TV.  Macs currently don't support mirroring but do support iTunes Airplay.
    So Netflix - not currently.
    YouTube/Vimeo - yes.
    Stream content from Apple - yes - if you have a slow (<6 Mbps) connection HD wil have to prebuffer for minutes to hours depending on speed of connection (4 Mbps takes 30-40 mins for movie to prebuffer).  If you have a slow connection you can rent in SD near instantly if you have 2.5 Mbps or so.  You can also rent in iTunes and play on AppleTV but choice is different (less HD).
    TV Shows - no rentals anymore anywhere but purchased shows in itunes can be streamed over LAN.
    Also iCloud support will emerge eg Photostream and who knows what else in the future (US ahead of us with streaming content from Apple's servers of purchases previously made and 'available').

  • What is the main benefit of  buying an ipad ? what can you actually do in 16, 32 0r 64 gb when you have 510 gb laptop with you ?

    What is the main benefit of  buying an ipad ? what can you actually do in 16, 32 0r 64 gb when you have 510 gb laptop with you ?

    For me? the advantage of an ipad over a laptop....instant on, instant off, thin and portable. Check your e-mail and put it down, not wait 5 minutes to boot, check your mail, shut it down.
    Is it as fully functional as a laptop? no. Not meant to be. What it lacks in functionality it makes up for in portability.
    Is a necessity? no. But quite handy.

  • How can I reuse the BC4J database connection?

    How can I reuse the BC4J database connection?
    I want to use the application module connection without opening another in a custom code. At this level I can’t access de ADF code, that’s why I can’t get the DBConnection from the application module.
    Now, I have a “data-sources.xml” in my project and the application module is configured to access the database from this xml file.

    I found the solution in other Forum. I worked ok.
    Here the code:
    If the Connections-Navigator connection is DBConnection1, the corresponding datasource is jdbc/DBConnection1DS.
    1. Create a JSP page.
    2. In the web.xml of the JSP add
    <resource-ref>
    <res-ref-name>jdbc/DBConnection1DS</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
    </resource-ref>
    3. In the JSP page obtain a connection with the datasource.
    InitialContext initialContext = new InitialContext();
    javax.sql.DataSource ds = (javax.sql.DataSource)initialContext.lookup("java:comp/env/jdbc/DBConnection1DS");
    java.sql.Connection conn = ds.getConnection();

  • What can I _really_ do with Flash.ocx in a Windows program

    (posted a few days ago in macromedia.players.flash with no
    answers;
    maybe this group is more applicable?)
    I've used Flash.ocx as an ActiveX control embedded in a
    Delphi program
    before. Works ok.
    What I'm wanting to learn about is how far I can push this
    thing? What
    can I really do with it?
    Can I load a SWF as a LoadMovie and then do more with it/to
    it? Can I
    load two or three SWF files and make them play one after the
    other? Can
    I edit SWFs somehow (I'd love to be able to load a SWF and
    "mute" it,
    for example)?
    Any good websites or references for the possibilities, other
    than
    "embed it and assign a file to the Movie property"?
    Thanks.

    I also want to know how to mute it. But I cannot find the way
    to realize it anywhere.

  • How to make Siri say "What can I help you with"

    I just got the iPhone 5 (my very first iPhone as well), I hold the home button to activate Siri but she won't say anything and it only shows the text of "What can I help you with?" at the bottom. How can I make her talk? I know that I have it activated for speech because after that when I say a command she'll respond when it stops loading. Also, I added my name as a contact but I haven't had her address me once by it. Does anyone know how to fix these two things? Thank you!

    So is the only reason for her to know your name to have her know you contacts info?
    Does she ever greet you with your name?

  • Problem with database connectivity

    Hi guys,
    I'm having a problem with database connectivity . I'm using the mySQL database & org.gjt.mm.mysql driver.
    I've kept the org folder under the directory where the Database.java program is residing .
    My program is as follows:
    import java.sql.*;
    public class Database
         Connection con;
         public void connect()
              System.out.println("In connect.");
         public Connection connectDB(String username,String password,String database)
              try
                   Class.forName("org.gjt.mm.mysql.jdbc.Driver");
                   String url="jdbc:mysql:"+database;
                   con=DriverManager.getConnection(url,username,password);
              catch(SQLException e)
                   System.out.println("SQL Exception caught:"+e);     
              catch(Exception e)
                   System.out.println("Exception e caught:"+e);     
              return con;
         public static void main(String args[])
              try
              Connection c;
              Database db=new Database();
              c=db.connectDB("root","","//192.168.0.2/squid");
              System.out.println("Connection created.");
              c.close();
              catch(Exception e)
                   System.out.println("Exception caught:"+e);     
    It gets compiled but gives the following error when run.
    Exception e caught:java.lang.ClassNotFoundException: org.gjt.mm.mysql.jdbc.Driver
    Connection created.
    Exception caught:java.lang.NullPointerException
    I don't know why the class is not found.Pl . help me rectify my mistake.Is there any other path to be set?
    Thanks.

    You need to run it with the JDBC driver in the classpath

    Can you make Siri say your name each time she says "What can I help you with?" I have done the "call me (my name) and linked her to my contacts but she rarely uses my name unless I ask "who am I?"  Can she say "What can I help you with (my name)"

    So is the only reason for her to know your name to have her know you contacts info?
    Does she ever greet you with your name?

  • Siri not saying what can i help you with

    I just received m iphone 5.
    Siri initially greeted me with the message "What can I help you with" verbally.  That has suddenly stopped.  Siri works fine for all other requests.  It seems odd that it just stopped.
    I've done a reset and restore backup and that did not change anything.  I have not done a full system restore yet.
    Any suggestions?

    Thanks, I'm betting that's it.  I tried it fresh out of the box, then activated the phone, updated the OS and reinstalled my data.
    Thanks for the reply!

  • How can I use SQL TOOLKIT concurrently with Database Connectivity ?

    I have installed LabVIEW 6.1 with the Database Connectivity Toolkit and the SQL Compatibility Toolkit (e.g. _SQL folder). I am trying to make the transition from the SQL Toolkit VIs to the Database Connectivity toolkits, but for compatability with existing systems I would like to be able to run the two sets of VIs concurrently (but not in the same app).
    When I read into 6.1 a connection VI that I wrote with LabVIEW 6.0 and the SQL toolkit the connection reference type gets changed from a number to type connection (see attachments) . Does compatbility mean that my SQL toolkit VIs are converted to a form compatible with the new ADO ?
    Can I use the SQL Toolkit VIs or the Database connectivit
    y VIs in the same installation of 6.1 ?
    Can I have the SQL Toolkit VIs appear on the functions pallette and function as they did when only the SQL toolkit was installed ?

    In response to your #2 below:
    Actually it is possible to have the old SQL Toolkit and new Database
    connectivity in the same installation of LabVIEW. I have only tried it on
    6i, but don't see why it wouldn't work on 6.1. The trick is not to install
    the SQL toolkit compatabitily VI's. The old SQL toolkit uses the Intersolve
    dll through ODBC while the new Database connectivity uses ADO so it is
    possible to use both methods not only in the same LabVIEW install, but it
    the same running application. It has been a while since I originally did
    this, so I am posting only to mention that it is possible and not exactly
    how to do it. If anyone is interested in more details just respond.

  • Problem with database connectivity toolkit

    I have problem with Labview database connectivity toolkit. I build and deploy the real_web.vi (attached to the post) to the web server. It seems that the DB Tools Open Connect can not connect to the data base, and it issues the following error:
    NI_Database_API.lvlib:DB Tools Open Connec (String).vi->real_web.vi->real_web.vi.ProxyCallerADO Error: 0x80004005 Exception occured in Microsoft OLE DB Provider for ODBC Drivers: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified in NI_Database_API.lvlib:DB Tools Open Connec (String).vi->real_web.vi->real_web.vi.ProxyCaller
    But in highlight execution, I do not get this error! My program connects to the database and read the data. What is wrong ?
    Moreover, when I connect to the vi using the web-browser, the cpu usage of ApplicationWebServer process goes up to 100% (The same problem as stated in this post).

    Say what you will about the problems that the DCT can cause (and goodness knows I have) my suspicion is that this is not a toolkit ptoblem. When ever something only works with execution highlighting on, two words should immediately jump to mind: "race" "condition".
    Execution highlighting will muck aound with the order in which things get done in your code. Can you post what your code looks like?

  • Processes 'stuck' after problems with database connection

    First in the production environment, during database failover (MSSQL Server cluster), and later in testing, we encountered processes that are 'stuck' on some random operation. Admin console doesn't show stalled operation or branches, process is running, all operations are completed except last which was in several cases still in status Running, and in one case it was Completed but next operation was not started.
    When operation is still running one would expect to select it and click 'Retry' in hope that process will continue but it seems there exist a bug in "Process Instance Detail" part of the admin console - it gives an error: "This operation cannot be completed without the selection of one or more operations from the list below!"
    We can try using 'Terminate' for this operation and probably several that follow (because they would probably stall without data from first terminated operation) in hope that process which runs in big user loop can arrive at a step where it can recover from all this using existing data but it's messy and doesn't always work.
    When the operation is in status Completed admin cannot do anything at all. This completed operation cannot be retried or terminated because selection box is grayed out. Process and data in it is irrecoverably lost and must be initiated from start.
    I must say we had large problems before if database connection is lost even for few seconds (intentional fail over from one db node to another) - but now, when we filled check-connection-sql in datasource configuration Livecycle is behaving a lot better but still with above problems.
    How can it happen that LC stops executing process workflow and stops on some operation just because it wasn't able to get valid db connection for several seconds? Is it some problem with transactions or what? What can I do? Where to look?
    We are still on LC ES2 SP3. JBoss on Windows Server 2003 and MSSQL 2005.
    Any help is appreciated.

    I would suggest you to contact the Adobe support so they can look further in system as well as LC database.

  • Problem with Database Connections in the designer - Catalog not updated

    This is Crystal Reports 2008 (12.2.0290). We have a number of reports that are viewed using the .Net runtime with the connection details set at runtime using ODBC to talk to SQL Server on different systems. This all works fine and is not the problem. The problem is when editing reports in the designer take the following example:
    Developer 1 creates report on their machine that references tables. DSN Name is DEV_DSN, pointing at their local database on their machine called DEV_DB1. Developer 2 needs to edit the report on their machine with a DSN of the same name (DEV_DSN) but this points to a different database on developer 2's machine called DEV_DB2.
    Developer 2 goes to the Set Datasource Location option in the Database menu to get it to point at their local DB only it doesn't work. They click on the first table included  (or the connection name) in the report and click update - they are prompted for the logon details for their local DSN/DB and supply them but they see an error indicating that there is an "Invalid object name" because the table is still being prefixed with the database name from developer 1's machine. When the table is expanded in this view the Catalog still shows as the DB name from developer 1's machine despite the connection properties above correctly showing the local DB name.
    As I say this is a design time issue not a runtime issue.
    Any ideas? Is there any way we can edit the Catalog name manually?

    Try setting the Over ridden qualified Table Name
    Set Datasource - > Tablename -> Properties
    Double click Over ridden qualified Table Name, type name as shown in in the table name field above it.
    Repeat for each table, this removes schema and db names associated with Table. Take a look at the SQL and make sure all tables are no longer prefixed.
    Report should now be totally portable.
