  • Database security / scaling question

    - by orokusaki
    Typically I use a database such as MySQL or PostGreSQL on the same machine as the application using it, which makes access easy and secure. I'm just now building the first site that will have a separate physical database server (later this year it will). I'm wondering 3 things: (security) What things should I look into for starters pertaining to security of accessing a separate machine's database? (scalability) Are their scalability issues that I should think about pertaining to this (technology agnostic)? (more ServerFaultish but related) If starting the DB out on the same physical server (using a separate VMWare VM) and later moving to a different physical server, are there implicit problems that I'll have to deal with? Isn't another VM still accessed via localhost? If these questions are completely ludicrous, I apologize to you DB experts.

    - by ThinkCode
    Following is a sample of sets of contacts for each company going from left to right. ID Company ContactFirst1 ContactLast1 Title1 Email1 ContactFirst2 ContactLast2 Title2 Email2 1 ABC John Doe CEO [email protected] Steve Bern CIO [email protected] How do I get them to go top to bottom as shown? ID Company Contactfirst ContactLast Title Email 1 ABC John Doe CEO [email protected] 1 ABC Steve Bern CIO [email protected] I am hoping there is a Pythonic way of solving this task. Any pointers or samples are really appreciated! p.s : In the actual file, there are 10 sets of contacts going from left to right and there are few thousand such records. It is a CSV file and I loaded into MySQL to manipulate the data.

  • Server database -> client database update based on version

    - by user296191
    Hi, What is the recommended method of collecting items in a server database, versioning the database then deploying only the version differences to a client ? Should it by a field in the table (ie. Version: 3.3.9876) against each record ? Should it be DateTime (server based) in each record ? And whats the best way to just deploy the changes to a client with an older version of the database ? Is it a DUMP to a file with a Bulk import of some description ? Open to comments.. Suggestions. Database can be anything (firebird, mysql, sqlserver, sqlite)... Any info greatly appreciated.

  • Eclipse plugins for Spring / Hibernate development?

    - by es11
    I have a running dynamic web project in Eclipse (Java EE + Maven + Spring). I am at the point where I need to integrate a persistence layer and want to use Hibernate with a mySql database. I am wonder what plugins would be useful for me at this point? For Hibernate should I install hibernate tools or is it not necessary? Are then any plugins that are most widely use for connecting / exploring database connections that would be appropriate for the type of project I am working on? Thanks.

  • SQL UPDATE order of evaluation

    - by pilcrow
    What is the order of evaluation in the following query: UPDATE tbl SET q = q + 1, p = q; That is, will "tbl"."p" be set to q or q + 1? Is order of evaluation here governed by SQL standard? Thanks. UPDATE After considering Migs' answer, I ran some tests on all DBs I could find. While I don't know what the standard says, implementations vary. Given CREATE TABLE tbl (p INT NOT NULL, q INT NOT NULL); INSERT INTO tbl VALUES (1, 5); -- p := 1, q := 5 UPDATE tbl SET q = q + 1, p = q; I found the values of "p" and "q" were: database p q -----------------+---+--- Firebird 2.1.3 | 6 | 6 InterBase 2009 | 5 | 6 MySQL 5.0.77 | 6 | 6 Oracle XE (10g) | 5 | 6 PostgreSQL 8.4.2 | 5 | 6

  • List of resources to learn cassandra

    - by Alfred
    Hi all, Lately I have been reading a lot of blog topics about big sites(facebook, twitter, digg, reddit to name a few) using cassandra as their datastore instead of MysqL. I would like to gather a list of resources to learn using cassandra. Hopefully some videos or podcasts explaining how to use cassandra. My list Twissandra - Twissandra is an example project, created to learn and demonstrate how to use Cassandra. Running the project will present a website that has similar functionality to Twitter WTF is a supercolumn - WTF is a SuperColumn? An Intro to the Cassandra Data Model I hope there are resources to watch howto use cassandra. Many thanks, Alfred

  • Quickest and easiest way to implement speech to text conversion for a small speech subset.

    - by sgtpeppers
    Hi, I want to implement a system that receives speech through a microphone on my Mac OS x. I know arbitrary speech recognition is close to impossible without training the system so I'm willing to restrict it to 10 simple sentences. It must recognize with a high degree of accuracy which of these 10 sentences are being spoken, generate the text and add an entry to a remote MySQL database. With these being the architecture of the system I want to implement, could anyone give me an overview of what would be the best way to go about implementing this system? I'm looking for ideas like open source libraries to minimize the coding as this is just a prototype application for a demonstration. Basically I'm looking for a quick and easy solution. Thanks!

  • Elmah on MVC website with WordPress/php sub directory

    - by creativeincode
    I have created a website using ASP.NET MVC and use ELMAH for error handling, this works perfectly. After setting up a virtual directory on my website under /blog and adding the necessary WordPress php files and mysql db, I get the below error come up. Could not load file or assembly 'Elmah' or one of its dependencies. The system cannot find the file specified. I think this has something to do with the fact that ELMAH is applying itself to all sub-directories. Is there a way that I can tell ELMAH to ignore everything under /blog? Or is there a way to get around this? Thanks in advance.

  • Using pyodbc to insert rows into a MS Access MDB, how do I escape the paramaters?

    - by MDBGuy
    Hi, I'm using pyodbc to talk to a legacy Access 2000 .mdb file. I've got a cursor, and am trying to execute this: c.execute("INSERT INTO [Accounts] ([Name], [TypeID], [StatusID], [AccountCat], [id]) VALUES (?, ?, ?, ?, ?)", [u'test', 20, 10, 4, 2]) However, doing so results in pyodbc.Error: ('HYC00', '[HYC00] [Microsoft][ODBC Microsoft Access Driver]Optional feature not implemented (106) (SQLBindParameter)') I understand I can simply change the question marks to the literal values, but in my experience proper escaping of strings across databases is... not pretty. PHP and mysql team up to bring mysql_real_escape_string and friends, but I can't seem to find pyodbc's function for escaping values. If you could let me know what the recommended way of inserting this data (from python) is, that'd be very helpful. Alternatively, if you have a python function to escape the odbc strings, that would also be great. Thanks for the help.

  • Licencing: release the same software with double licence

    - by Luca
    In my free time, I develop (alone, sigh) a project, in particoular an application library. I've released it using GPL v3. At this time, this project has come very useful for a job. I'd like to release my OSS library toghether with the application using the same GPL v3 licence, with the exception that it can be linked for the specific application, or for the specific application vendor. AFAIK, the copyright owner can handle the entire source and licencing it, I did it; and probably the licence owner could cut&paste its own code, change its licence and use for other projects, isn't? But an GPL'ed library cannot be linked with a proprietary software, right? But software could be double-licenced, as MySQL does. So the question is: what should I do to allow the distribution of my GPL'ed library with a proprietary software, being the copyright owner?

  • Symfony Jobeet Tutorial Day 3, databases.yml error

    - by Tony
    Hi all, I'm new to Symfony and I'm going through the Jobeet tutorial v1.4 for Doctrine. I am currently stuck on Day 3. I've followed all the instructions on configuring the database and building models and modules; however, when I try to access "http://localhost:8080/frontend_dev.php" I receive the following error: 'Configuration "config/databases.yml" does not exist or is unreadable.' My config/databases.yml file looks like this: all: doctrine: class: sfDoctrineDatabase param: dsn: 'mysql:host=localhost;dbname=jobeet' username: root password: mysecret Creating the tables and loading the fixtures seem to work fine after checking the database with phpmyadmin. Any help would be appreciated. Thank you!

  • Free data warehouse - Infobright, Hadoop/Hive or what ?

    - by peperg
    I need to store large amount of small data objects (millions of rows per month). Once they're saved they wont change. I need to : store them securely use them to analysis (mostly time-oriented) retrieve some raw data occasionally It would be nice if it could be used with JasperReports or BIRT My first shot was Infobright Community - just a column-oriented, read-only storing mechanism for MySQL On the other hand, people says that NoSQL approach could be better. Hadoop+Hive looks promissing, but the documentation looks poor and the version number is less than 1.0 . I heard about Hypertable, Pentaho, MongoDB .... Do you have any recommendations ? (Yes, I found some topics here, but it was year or two ago)

  • Light-weight client/server DB?

    - by OverTheRainbow
    Hello, (This question falls between programming and finding a tool, so I guess I'll ask here in SO since it has more activity than SuperUser.) I like the simplicity of SQLite, but by design, it doesn't support concurrent access. The apps I write don't have heavy needs, so I'd like to avoid heavier solutions like MySQL that are more difficult to deploy (remote customers with usually no computer personnel). Does someone know of a good solution that would offer the following features? Client available for VB.Net applications The server itself doesn't have to be a .Net application. Actually, I'd rather a bare-metal server so that it can run even on embedded Linux hosts with less RAM/CPU than regular PC's Easy install: the client part should either be statically linked inside the client application or be available as a single DLL, and the server should just be a single EXE listening for queries, à la Fossil (http://www.fossil-scm.org) clients can locate the server on the LAN by broadcasting data picked up by the server, so users don't have to write down the IP address and paste it into each client open-source, or moderately priced closed-source Thank you.

  • PHP gallery, thumbnail listing

    - by Benjamin
    Hi everyone, I am planning a dynamic PHP photo gallery and having difficulty deciding on the best way to display the thumbnails after they have been retrieved via MySQL. I considered using an inline unordered list but this resulted in the thumbs being stacked one on top of the other (touching). Also tried a table but not sure how I would start the next row after x number of thumbnails. Any suggestions on page layout for this purpose? I will be using Lightbox to cycle through the photos themselves, that isn't the issue. Also, would a while() loop be best for fetching the list of thumbs and inserting the appropriate HTML? Thanks! -Ben

  • Current ways to do data binding in .NET 3.5 with C# 3.0 and WinForms

    - by kryptic
    Hello Everyone, I have an existing C# 3.0 WinForms project with .NET 3.5 that talks to a MySQL database. I would like to use data binding (I'm new to this, so I've been doing all of the UI updates manually) to simplify things. I followed a link from this question to this article which mentions using a DataSet but also follows up with "my view on this topic is strongly in favor of Business Objects." Also that was with .NET 2.0. What are the current methods to use data binding with a WinForms application? What are their advantages in terms of simplicity, how much additional code is necessary, etc. For reference, I use an ORM approach to build objects with public properties from a database. I want to map these properties for each object onto UI elements like TextBoxes. There could be many properties for an object so I want to simplify the code to do this.

  • SQLServer Binary Data with ActiveRecord and JDBC

    - by John Duff
    I'm using the activerecord-jdbc-adapter with ActiveRecord to be able to access a SQLServer database for Rails Application running under jRuby and am having trouble inserting binary data. The Exception I am getting is below. Note I just have a blurb for the binary data from the fixtures that was working fine for MySQL. ActiveRecord::StatementInvalid: ActiveRecord::ActiveRecordError: Operand type clash: nvarchar is incompatible with image: INSERT INTO blobstorage_datachunks ([id], [datafile_id], [chunk_number], [data]) VALUES (369397133, 663419003, 0, N'GIF89a@') When I created the tables the migration had binary and SQLServer used Image instead. We're using Rails 2.3.5, SQLServer Express 2008. What I'm looking for is a way to get the binary data into SQLServer with ActiveRecord. Thanks in advance for the help.

  • Hibernate configuration files not found by Axis2

    - by DanJo519
    I am writing a web service to be deployed on Tomcat using Axis2. I am using Hibernate3 to persist data between the web service and a MySQL database. When running the application through by IDE, the method I am exposing through Axis2 works as intended, however when I deploy the .aar to Tomcat, I receive a SOAP Error claiming that hibernate.cfg.xml cannot be found. However, inside the .aar, I clearly see that all the configuration file and all the mapping files are included. I have determined a workaround: If I place the resulting files from the Netbeans build/class folder into the axis2/WEB-INF/class folder, then the application works as expected. My question, then, is is there a better way to deploy my application so that Axis2 will pick up the configuration and mapping files through the deployed .aar without my manually having to copy the contents of the build/class folder into the axis2/WEB-INF/class folder?

  • Modifing settings in Django

    - by Cato Johnston
    I'm trying to get Django's manage.py to run with modified settings files. I have three settings files settings.py preview.py live.py settings.py contains my base settings but on live & preview sites I point the ['DJANGO_SETTINGS_MODULE'] to live or preview which in turn load the base file and any settings specific to that environment. This works fine, until I try to run migrations using manage.py I updated the manage.py file to import settings.preview but now when I try to run syncdb or migrate I get this error: django.core.exceptions.ImproperlyConfigured: You haven't set the DATABASE_ENGINE setting yet. My settings file has this in it though: DATABASE_ENGINE = 'mysql' How can I get this to work?

  • Getting the count of rows in a Java resultset

    - by Mr Morgan
    Hello Does anyone know a better way of getting the number of rows in a Java resultset returned from a MySQL database? I'm currently using this: public static int getResultSetRowCount(ResultSet resultSet) { int size = 0; try { resultSet.last(); size = resultSet.getRow(); resultSet.beforeFirst(); } catch(Exception ex) { return 0; } return size; } But am open to alternatives. The resultset returned is not going to be the total number of rows read from the database so I don;t think I can use SQL COUNT. Thanks Mr Morgan.

  • TinyMCE not working in http request xhr ajax generated page

    - by user982853
    So i I have a page that contains links that call an httpRequest. The request calls a php file that grabs data from mysql and pre populates a form which is then returned to the browser/webpage. My problem is that when the page is returned to the browser via the httpRequest/ajax the text area does not display the tinymce editor, it just displays a normal text area. It looks like my request and ajax is working fine the text area just doesn't have the tinycme editor on it. When i don't use ajax it works fine but when i put it in a separate file and call it via ajax it doesn't bring in the tinymce editor. Does anyone know how to fix this problem so that my ajax generated page displays the text area with the tinymce editor. Thank you.

    Hi, I have recently taken on a project in which I need to integrate with PHP/SQL Server. I am looking for the quickest and easiest function to prevent SQL injection on SQL Server as I prefer MySQL and do not anticipate many more SQL Server related projects. Is this function sufficient? $someVal = mssql_escape($_POST['someVal']); $query = "INSERT INTO tblName SET field = $someVal"; mssql_execute($query); function mssql_escape($str) { return str_replace("'", "''", $str); } If not, what additional steps should I take?
