  • Recommendation needed for text content, should I use text files or database?

    - by Jörgen
    I'm doing a web application in asp.net mvc. Now I'm at the point where I do alot of text info such as help texts, eula, privacy policy etc. I realized that I'm not sure what would the best way to store these texts. 1. Directly in the aspx page 2. In text files and then load the text via ViewData[] to the aspx file 3. In my sql database If use option 3 how would I then design the database e.g. eula = table x, privacypolicy=table y? I guess I just need some directions of what't the pros and cons with the options above.

  • How do you handle descriptive database table names and their effect on foreign key names?

    - by Carvell Fenton
    Hello, I am working on a database schema, and am trying to make some decisions about table names. I like at least somewhat descriptive names, but then when I use suggested foreign key naming conventions, the result seems to get ridiculous. Consider this example: Suppose I have table session_subject_mark_item_info And it has a foreign key that references sessionSubjectID in the session_subjects table. Now when I create the foreign key name based on fk_[referencing_table]__[referenced_table]_[field_name] I end up with this maddness: fk_session_subject_mark_item_info__session_subjects_sessionSubjectID Would this type of a foreign key name cause me problems down the road, or is it quite common to see this? Also, how do the more experienced database designers out there handle the conflict between descriptive naming for readability vs. the long names that result? I am using MySQL and MySQL Workbench if that makes any difference. Thanks!

  • How to rollback a database deployment without losing new data?

    - by devlife
    My company uses virtual machines for our web/app servers. This allows for very easy rollbacks of a deployment if something goes wrong. However, if an app server deployment also requires a database deployment and we have to rollback I'm kind of at a loss. How can you rollback database schema changes without losing data? The only thing that I can think of is to write a script that will drop/revert tables/columns back to their original state. Is this really the best way?

  • Encrypt/Decrypt SQLite-database and use it "on the fly"

    - by Berschi
    Here's the thing: In my Qt4.6-Project, I use a SQLite-Database. This database shouldn't be unencrypted on my harddrive. So I want, that on every start of my program, the user gets asked to enter a password to decrypt the database. Of course the database never should appear "in clear" (not encrypted) on my harddrive. So is there any possibility to decrypt a SQLite-database "on the fly" and read and write data? What algorithm is here the best (maybe AES)? When it's not possible (or very slow), maybe it's better to encrypt every string in the database and decrypt the string when the password was right (so that a user could open the database, but has no clue what all the entrys could mean)?

  • Simulate the user clicking on a link

    - by timkl
    I want a link to be clicked when a key is pressed, I cooked up this jQuery: $('form#form1').bind("keypress", function(e){ if(e.keycode == 13 || e.keyChar == 13 || e.which == 13){ $('.LoginBoxButton a').click(); } }); It doesn't work, and I've read the following explaining why: It's important to remember that click() will not trigger the default behavior on a link, even if nothing else is preventing it. So you can't use click() by itself to simulate the user clicking on a link and being taken to another url. But how DO you simulate the user clicking on a link and being taken to another url?

  • Automatic clicking on Link build with Javascript by using watin

    - by BEC Roland
    I am trying to be able to automate the process of clicking on links built in javascript using watin. In the source code of web page, the links look like href="#", so i think these links works with Javascript. Runscript doesn't work with a Javascript code like "link.click". When i use a "link.flash()" i can see the link flash so i'm sure the script click on the links but there is not effect ( and the script doens't crash ) . Have you any ideas for resolve this problem ?

  • Microsoft Database project requires Visual studio 2010 premium or higher? Are there any open source

    - by skurge
    Hello, I need to know wether or not to buy the VS 2010 premium or not. I have the database project working on my own version of vs 2008 team suite. My coworkers only have 2008 professional. We are moving to VS2010 now. We do not have MSDN licenses for our company right now. We are looking to buy just the VS2010 no MSDN. It is very pricey to get 6 of VS2010 premium. We need to get our database into source control. We are currently email scripts around, and it very difficult to keep track off. Are there any non-microsoft solutions that would be the same features and be free?

  • mySQL database password change now crashes Joomla.

    - by casim
    I have a mySQL database behind a Joomla install. I changed the database password because I forgot it but now Joomla crashes looking for the database. I guess joomla has the password written somewhere - if anyone knows I might be able to manual edit it and enter the new database password. Otherwise I'm hoping a manual install of a backup of the original database will work. I need to know does a backup include the database password. If yes, will reinstating my original database solve the problem for me by reverting the system back to it's original password? Please help. thx, s.

  • Can a binary tree or tree be always represented in a Database as 1 table and self-referencing?

    - by Jian Lin
    I didn't feel this rule before, but it seems that a binary tree or any tree (each node can have many children but children cannot point back to any parent), then this data structure can be represented as 1 table in a database, with each row having an ID for itself and a parentID that points back to the parent node. That is in fact the classical Employee - Manager diagram: one boss can have many people under him... and each person can have n people under him, etc. This is a tree structure and is represented in database books as a common example as a single table Employee.

  • How to link pnglite library in c?

    - by zaplec
    Hi, I installed from kubuntu's package management this handy pnglite library. It contains just one header file "pnglite.h" and one object file "pnglite.o". I have found out where those files are, but I don't know how to link them. I'm using netbeans, but don't know how to link them in there. Also I don't understand how to link them at console. I have a little test program that I would like to test, but I get the error message "undefined reference to function: XXXXXXX". Both netbeans and at console I'm using gcc. That header file is in /usr/include directory, object file is in /usr/lib directory and my test program is under my programming directory at my home directory. Should I put that header and object into the same directory as where my source is? Or is there a way to link them from their current locations? I know that it should be possible to link them from where they are at the moment and I would like to know and understand how to do that. Any help will be appreciated :)

  • SQL Error (1064) when importing data from SQL file

    - by mejpark
    I have a MySQL database, which was originally set up with the default latin1 character set and latin1_swedish_ci collation. I was using the database like this for sometime, until I noticed strange characters on my production web site, which is powered by a database exported from my development machine. At this point, I changed the default character set of the database and tables to utf8 and the collation to utf8_unicode_ci, converted the latin1 data inside each table to utf8 (using the 'convert data' option) and exported the database as a single SQL file using HeidiSQL. When the resulting SQL file is opened in Notepad++, several characters are rendered incorrectly. For example, en dashes (-) are displayed as – and e with accent (é) are displayed as é. I changed the encoding of the file from ANSI to UTF-8 (using the encoding menu option in Notepad++) and the offending characters are rendered correctly. I saved the new utf8-encoded SQL file and attempted to import the contents into the MySQL database on my production server. The import process fails with following error: /* SQL Error (1064): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '?# -------------------------------------------------------- # Host: ' at line 1 */ /* Error with snippets directory: The specified path was not found */ The head of the SQL file: # -------------------------------------------------------- # Host: 127.0.0.1 # Server version: 5.1.33-community # Server OS: Win32 # HeidiSQL version: 6.0.0.3773 # Date/time: 2011-04-20 09:48:36 # -------------------------------------------------------- It chokes on the first line of the file, which is commented out. Why is this happening? I didn't have a problem loading data from SQL files until I changed the character set and collation of the database. I came up with an ugly workaround to this problem by performing following steps: Export database as single SQL file using HeidiSQL Open resulting file in Notepad++ and convert from ANSI to UTF-8 encoding Create new empty file in Notepad++, paste in UTF-8 and save file normally What am I missing here?

  • How to select the nth row in a SQL database table?

    - by Charles Roper
    I'm interested in learning some (ideally) database agnostic ways of selecting the nth row from a database table. It would also be interesting to see how this can be achieved using the native functionality of the following databases: SQL Server MySQL PostgreSQL SQLite Oracle I am currently doing something like the following in SQL Server 2005, but I'd be interested in seeing other's more agnostic approaches: WITH Ordered AS ( SELECT ROW_NUMBER() OVER (ORDER BY OrderID) AS RowNumber, OrderID, OrderDate FROM Orders) SELECT * FROM Ordered WHERE RowNumber = 1000000 Credit for the above SQL: Firoz Ansari's Weblog Update: See Troels Arvin's answer regarding the SQL standard. Troels, have you got any links we can cite?

  • ADO.NET: Faster way to check if the database server is accessible?

    - by lotana
    At the moment I am using this code to check if the database is accessible: public bool IsDatabaseOnline(string con) { bool isConnected = false; SQLConnection connect = null; try { connect = new SQLConnection(con); connect.Open(); isConnected = true; } catch (Exception e) { isConnected = false; } finally { if (connect != null) connect.Close(); } return isConnected; } While this code works fine, there is a disadvantage. If the server is not online it spends about 4 full seconds trying to open the connection before deciding that it is not available. Is there a way to test the connection without trying to actually opening it and waiting for the timeout? Something like a database-equivalent of ping?

  • How to schedule a cron job to backup a MySql database every week?

    - by KevinM
    What is a command line I can use to back up a MySql database every single week into a file name with the date (so that it doesn't collide with previous backups)? Also, is this a reasonable backup strategy? My database is relatively small (a complete export is only 3.2 megs right now). The churn rate is relatively low. I need to be able to get the complete DB back if something goes wrong. And it would be extra cool if there's a way that I could see the changes that occur across a time span.
