  • C# MySQL Connector works in IDE, not after publish?

    - by MTBPatriot
    For some reason I can't seem to get the MySQL Net Connector to work with C# outside of the IDE. I have a very simple program working just fine in the IDE (connecting to the database and everything) but when I publish the code and run the .application file (on my local computers desktop or off the company server) it says it can't connect to any of the specified MySQL hosts. Any help would be greatly appreciated! :( Thank you

  • Importing old mysql data folder

    - by samgoody
    After a reinstall, all of the old data still shows inside the MySQL/data folder, but is not actually loaded into the database. Is there any way to have MySQL scan it's data folder and / or reimport the old folders it has from its previous install? [Some data was changed after the last backup / export - partially my fault - so I would rather it recognize the folders rather than reimporting the SQL files.]

  • can the web.config be changed so roles wouldn't work any more?

    - by Scott J.
    I have had two instances of this problem, first on my local computer, now on the main site. Users can log in to the site, but it doesn't seem to recognize their roles. When I log in (which the database still recognizes as having the role admin), the code does not recognize it as being in the admin role. If there are other web.configs in subfolders, would that cause the problem? What could possibly cause this issue? Thanks! scojomodena

  • What should I learn & use to become a pro in PHP & Python Web development?

    - by pecker
    Hello, I'll just show some code to show how I do web development in PHP. <html> <head> <title>Example #3 TDavid's Very First PHP Script ever!</title> </head> <? print(Date("m/j/y")); require_once("somefile.php"); $mysql_db = "DATABASE NAME"; $mysql_user = "YOUR MYSQL USERNAME"; $mysql_pass = "YOUR MYSQL PASSWORD"; $mysql_link = mysql_connect("localhost", $mysql_user, $mysql_pass); mysql_select_db($mysql_db, $mysql_link); $result = mysql_query("SELECT impressions from tds_counter where COUNT_ID='$cid'", $mysql_link); if(mysql_num_rows($result)) { mysql_query("UPDATE tds_counter set impressions=impressions+1 where COUNT_ID='$cid'", $mysql_link); $row = mysql_fetch_row($result); if(!$inv) { print("$row[0]"); } } ?> <body> </body> </html> Thats it. I write every file like this. Recently, I learnt OOP and started using classes & objects in PHP. I hear that there are many frameworks there for PHP. They say that one must use these libraries. But I feel they are just making things complicated. Anyway, this is how I've been doing my web development. Now, I want to improve this. and make it professional. Also I want to move to Python. I searched SO archives and found everyone suggesting Django. But, can any one give me some idea about how web development in Python works? user (client) request for page --- webserver(-embedded PHP interpreter) ---- Server side(PHP) Script --- MySQL Server. Now, is it that instead of PHP interpreter there is python interpreter & instead of php script there is python script, which contains both HTML & python (embedded in some kind of python tags). Python script connects to database server and fetches some data which will be printed as HTML. or is it different in python world? Is this Django thing like frameworks for PHP? Can't one code in python without using Django. Because, I never encountered any post without django Please give me some kick start.

  • Is it expensive to hold on to PreparedStatements? (Java & JDBC)

    - by sbook
    I'm trying to figure out if it's efficient for me to cache all of my statements when I create my database connection or if I should only create those that are most used and create the others if/when they're needed.. It seems foolish to create all of the statements in all of the client threads. Any feedback would be greatly appreciated.

  • How to pass in password to pg_dump?

    - by Mark
    I'm trying to create a cronjob to back up my database every night before something catastrophic happens. It looks like this command should meet my needs: pg_dump dbname | gzip > $(date +%Y-%m-%d).psql.gz Except after running that, it expects me to type in a password. I can't do that if I run it from cron. How can I pass one in automatically?

  • In ruby on rails, is it possible to do a sum query with group by using the find_each batching?

    - by BarryOg
    I'm loading data from my database and I'm doing a sum calculation with a group by. ElectricityReading.sum(:electricity_value, :group => "electricity_timestamp", :having => ["electricity_timestamp = '2010-02-14 23:30:00'"]) My data sets are extremely large, 100k upwards so I was wondering if its possible to use the find_each to batch this to help with memory overhead. I can write the batching manually use limit and offset I guess but I'd like to avoid that if the code already exists.
