  • mysql C connector unresolved symbols on Win2k8 but not on XP?

    - by jimmy glick
    I have a visual C++ 2008 express project which compiles fine on Windows XP with mysql C connector 6.0.2. When I copy the project over to a Windows Server 2008 x64 machine, it gets a bunch of linker errors like "unresolved external symbol _mysql_server_end@0" "unresolved external symbol _mysql_close@4" "unresolved external _mysql_real_connect@32". Is the mysql C connector 6.0.2 known to not work with Win Server 2008? (Note, the C connector is installed into the same place on both machines, and since I just copied over the project wholesale, it still has the correct libmysql.lib include. The interesting thing is that the errors I get on XP if I remove the libmysql.lib are not the same errors I'm getting on Win2k8, so that's what makes me think it might be an incompatibility...or maybe it's just because win2k8 is x64 and XP is x86?) Thanks

  • Jetty embedded: How to run the same config as with `mvn jetty:run-exploded`?

    - by Ondra Žižka
    Hi, I'd like to have the same Jetty server configuration, created programatically. When I run mvn jetty:run-exploded, my app works fine. When I run it from my code, the static content is not loaded. I know that I have to add a static content Servlet, so I tried: Server server = new Server(8080); Context ctx = new Context( server, "/", Context.SESSIONS ); DefaultServlet defaultServlet = new DefaultServlet(); ServletHolder defaultSH = new ServletHolder( defaultServlet ); defaultSH.setInitParameter( "resourceBase", "./"); ctx.addServlet( defaultSH, "/img" ); ctx.addServlet( defaultSH, "/css" ); ctx.addServlet( defaultSH, "/js" ); I am assuming that the pwd is in the webapp's "root", i.e. where the WEB-INF dir is. This does not work. Anyway. Is somewhere a clean block of pure Java code which will give me the exact same server config as the mvn jetty:run-explodeds default? Thanks for help, Ondra

  • How to insert bulk data into mysql table from asp.net at once.

    - by kranthi
    Hi, I have a requirement that I need to read an excel sheet using asp.net/C# and insert all the records into mysql table.The excel sheet consists of around 2000 rows and 50 columns. Currently,upon reading the excel records ,I am inserting the records one by one using a prepare statement into mysql table.But its taking around 70 secs to do so because of the huge data. I've also thought of creating a new datarow, assigning values to each cell,adding the resulting datarow to datatable and finally calling dataadapter.update(...).But it seems to be complex because I got around 50 columns and hence I'll have to assign 50 values to the datarow. Could someone please suggest if there is an alternate to improve the performance of the insertion? Thanks

  • Hierarchical Data in MySQL is as fast as XML to retrieve?

    - by ajsie
    i've got a list of all countries - states - cities (- subcities/villages etc) in a XML file and to retrieve for example a state's all cities it's really quick with XML (using xml parser). i wonder, if i put all this information in mysql, is retrieving a state's all cities as fast as with XML? cause XML is designed to store hierarchical data while relational databases like mysql are not. the list contains like 500 000 entities. so i wonder if its as fast as XML using either of: Adjacency list model Nested Set model And which one should i use? Cause (theoretically) there could be unlimited levels under a state (i heard that adjacency isn't good for unlimited child-levels). And which is fastest for this huge dataset? Thanks!

  • Is there any reason to use C instead of C++ for embedded development?

    - by Piotr Czapla
    Question I have two compilers on my hardware C++ and C89 I'm thinking about using C++ with classes but without polymorphism (to avoid vtables). The main reasons I’d like to use C++ are: I prefer to use “inline” functions instead of macro definitions. I’d like to use namespaces as I prefixes clutter the code. I see C++ a bit type safer mainly because of templates, and verbose casting. I really like overloaded functions and constructors (used for automatic casting). Do you see any reason to stick with C89 when developing for very limited hardware (4kb of RAM)? Conclusion Thank you for your answers, they were really helpful! I though the subject through and I will stick with C mainly because: It is easier to predict actual code in C and this is really important if you have only 4kb of ram. My team consists of C developers mainly so advance features of C++ won't be frequently used. I've found a way to inline functions in my C compiler (C89). It is hard to accept one answer as you provided so many good answers. Unfortunately I can't create a wiki and accept it so I will choose one answer that made me think most.

  • Mysql SET NAMES UTF8 - how to get rid of?

    - by Nir
    In a very busy PHP script we have a call at the beginning to "Set names utf8" which is setting the character set in which mysql should interpret and send the data back from the server to the client. http://dev.mysql.com/doc/refman/5.0/en/charset-applications.html I want to get rid of it so I set default-character-set=utf8 In our server ini file. (see link above) The setting seems to be working since the relevant server parameters are : 'character_set_client', 'utf8' 'character_set_connection', 'utf8' 'character_set_database', 'latin1' 'character_set_filesystem', 'binary' 'character_set_results', 'utf8' 'character_set_server', 'latin1' 'character_set_system', 'utf8' But after this change and commenting out set names utf8 call still the data starts to come out garbled. Please advise....

  • Autmatically create table on MySQL server based on date?

    - by Anthony
    Is there an equivalent to cron for MySQL? I have a PHP script that queries a table based on the month and year, like: SELECT * FROM data_2010_1 What I have been doing until now is, every time the script executes it does a query for the table, and if it exists, does the work, if it doesn't it creates the table. I was wondering if I can just set something up on the MySQL server itself that will create the table (based on a default table) at the stroke of midnight on the first of the month. Update Based on the comments I've gotten, I'm thinking this isn't the best way to achieve my goal. So here's two more questions: If I have a table with thousands of rows added monthly, is this potentially a drag on resources? If so, what is the best way to partition this table, since the above is verboten? What are the potential problems with my home-grown method I originally thought up?

  • How to Connect to a Mysql database using PHP?

    - by Karthik
    <?php mysql_connect("localhost", "username", "password") or die(mysql_error()); echo "Connected to MySQL<br />"; ?> This is the code I am using to check if I am able to connect to Mysql. I am having problem connecting using this code. Should I change localhost to the name of the website? I tried ("www.abc.com","login username", "password") even this is not working.

  • Hopefully simple topic to spark some good opinions, Question is MySQL or SQL Server???

    - by magellings
    I'm beginning development of a website and a high priority is for it to be extremely optimized, quick responses, etc. There will ultimately end up being large amounts of rows in the main tables (millions), so scalability is also important. It will need to use a database on the back-end for data storage and my web hosting service supports either MySQL or Sql Server. This website will be developed with .NET ASP.NET MVC with NHibernate (hopefully it can run in medium trust mode, as that is a requirement of my web hosting and reflection requirements of NHibernate may be problematic, maybe someone has a comment on this too). I'd also prefer to use the database that will require the least attention in regards to management. I don't want to have to be a DBA here. :) I wanted to through this topic out to the public to see what the community thinks? So MySQL or Sql Server, generally, which one would be better to use?

  • Which collation should I use to store these country names in MySQL?

    - by morpheous
    I am trying to store a list of countries in a mySQL database. I am having problems storing (non English) names like these: São Tomé and Príncipe República de El Salvador They are stored with strange characters in the db, (and therefore output strangely in my HTML pages). I have tried using different combinations of collations for the database and the MySQL connection collation: The "obvious" setting was to use utf8_unicode_ci for both the databse and the connection information. To my utter surprise, that did not solve the problem. Does anyone know how to resolve this issue?

  • A consistent and simple group of IDE and tools for embedded code and unit test in C++ ?

    - by TridenT
    I’m starting a new firmware project in C++ for Texas Instrument C283xx and C6xxx targets. The unit tests will not run on the target, but will be compiled with gcc/gcov on a PC with windows (and run as well on PC) with simple metrics for tested code coverage. The whole project will be part of Cruise Control.NET for continuous integrations. My question is: what are the consistent IDE / framework / tools to work together? A/ One of the developers says CodeComposerStudio V3.1 for application and CodeBlocks + CxxUnit for the Unit tests. B/ I’m more attracted with CodeComposerStudio V4 for application, Eclipse CDT (well, as CCS V4) and CppUnit for unit test + MockCpp for mocks. I don’t want the best in class tools for each process, but a global, consistent and easy solution (or group of tools if you prefer).

  • How do I get phpMyAdmin to connect to a local mysql server?

    - by bryan
    Hi everyone, I have my config.inc.php file, and have set my host name to localhost. Unfortunately, I have no idea what my username/password should be. Is that something I need to configure on the MySql side? I tried creating an arbitrary username/password (admin/password), but when I try to log into phpMyAdmin with those credentials, I get an error: (#1045 - Access denied for user 'admin'@'localhost' (using password: YES)) Can anyone point me in the right direction? (Sorry for the dumb question; I just haven't had to install mysql before. I've always had a host name / username / password given to me.) Thanks!

  • pitfalls with mixing storage engines in mysql with django?

    - by Dave Orr
    I'm running a django system over mysql in amazon's cloud, and the database default is innodb. But now I want to put a fulltext index on a couple of tables for searching, which evidently requires myisam. The obvious solution is to just tell mysql to ALTER TABLE to myisam, but are there going to be any issues with that? One that comes to mind is that I'll have to remember to do that any time I build a new version of the database, which should theoretically be rare, but there doesn't seem to be a way to tell django to please set the storage engine at the table level. I guess I could write a migration (we use south). Any other things I might be missing? What could possibly go wrong?

  • Embedded C++, any tips to avoid a local thats only used to return a value on the stack?

    - by lisarc
    I have a local that's only used for the purposes of checking the result from another function and passing it on if it meets certain criteria. Most of the time, that criteria will never be met. Is there any way I can avoid this "extra" local? I only have about 1MB of storage for my binary, and I have several thousand function calls that follow this pattern. I know it's a minor thing, but if there's a better pattern I'd love to know! SomeDataType myclass::myFunction() { SomeDataType result; // do I really need this local??? // i need to check the result and pass it on if it meets a certain condition result = doSomething(); if ( ! result ) { return result; } // do other things here ... // normal result of processing return SomeDataType(whatever); }

  • Does it make sense to use BOTH mongodb and mysql in the same rails application?

    - by Brian Armstrong
    I have a good reason to use mongodb for part of my app. But people generally describe it as not a good fit for "transactional" applications like a bank where transactions have to be exact/consistent, etc. Does it make sense to split the models up in Rails and have some of them use MySql and others mongo? Or will this generally cause more problems than it's worth? I'm not building a banking app or anything, but was thinking it might make sense for my users table or or transactions table (recording revenue) to do that part in MySql.
