  • Does the order of columns in a query matter?

    - by James Simpson
    When selecting columns from a MySQL table, is performance affected by the order that you select the columns as compared to their order in the table (not considering indexes that may cover the columns)? For example, you have a table with rows uid, name, bday, and you have the following query. SELECT uid, name, bday FROM table Does MySQL see the following query any differently and thus cause any sort of performance hit? SELECT uid, bday, name FROM table

  • how to separate debug and release mode code

    - by john
    during debug mode or while i am doing testing, i need to print lost of various information, so i use this method ifdef TESTING // code with lots of debugging info else // clean code only endif // TESTING` Is this the good method, or is there any other simple and elegant method. But this way, I am repating the same code in two places and if anything is to be changed later on in the code, I have to do it in both places, which is time consuming and error prone. Thanks. I am using MS Visual Studio.

  • Windows batch file timing bug

    - by elbillaf
    I've used %time% for timing previously - at least I think I have. I have this weird IF NOT "%1" == "" ( echo Testing: %1 echo Start: %time% sqlcmd -S MYSERVER -i test_import_%1.sql -o "test_%1%.log" sleep 3 echo End: %time% ) I run this, and it prints: Testing: pm Start: 13:29:45.30 End: 13:29:45.30 In this case, my sql code is failing (different reason), but I figure the sleep 3 should make the time increment by 3 at least. Any ideas? tx, tff

  • App Engine Django Form Uniqueness Validation?

    - by GeekTantra
    Is there a simpler way to use uniqueness validation with Django Forms in AppEngine? I understand that performance would be problem if we keep an uniqueness constraint but since the amount of data being added is very small performance is not a big concern, rather development time is a concern here. Any help is appreciated.

  • Does running a SQL Server 2005 database in compatibility level 80 have a negative impact on performa

    - by Templar
    Our software must be able to run on SQL Server 2000 and 2005. To simplify development, we're running our SQL Server 2005 databases in compatibility level 80. However, database performance seems slower on SQL 2005 than on SQL 2000 in some cases (we have not confirmed this using benchmarks yet). Would upgrading the compatibility level to 90 improve performance on the SQL 2005 servers?

  • Unit Test Organization

    - by cam
    I'm using Nunit for unit testing, and added another project called "Unit Testing" to my current solution. I referenced Nunit, and changed the Namespace to the same namespace used in the main project. I can't seem to figure out how to get access to all the classes, files, etc in the main project. Is there something I have to do to link two projects?

  • mysql innodb:innodb_flush_method

    - by Daniel
    in the following link http://dev.mysql.com/doc/refman/5.1/en/innodb-parameters.html#sysvar_innodb_flush_method it says:Different values of this variable can have a marked effect on InnoDB performance. For example, on some systems where InnoDB data and log files are located on a SAN, it has been found that setting innodb_flush_method to O_DIRECT can degrade performance of simple SELECT statements by a factor of three. Why O_DIRECT could slow down the select statement?

  • SOAP VS REST PRAGMATIC CASE STUDIES ?

    - by asksuperuser
    I'm not satisfied with the answers given by the SOAP vs REST questions notably here: http://stackoverflow.com/questions/106546/performance-of-soap-vs-xml-rpc-or-rest because it's just general philosophical answers and not pragmatic answers with some study cases. Nobody can give precise cases of when soap would be more suitable than rest, especially as for performance point of view ? For example let's say I have a flash client for a financiall simulation wizard calling legacy code. Should I use SOAP or REST ? Why ?

  • setAction for NSMatrix Not Working

    - by PF1
    Hi Everyone: I am attempting to call a function when any cell in a NSMatrix instance is selected. I am using the following code in order to accomplish this: [[cellArray objectAtIndex:0] setAction:@selector(testing:)]; [[cellArray objectAtIndex:1] setAction:@selector(testing:)]; However, when I toggle the selection of the two cells, the function isn't run. Is my method of setting the action of each cell incorrect, or is the problem located somewhere else? Thanks for any help.

  • How big in bytes is a DataRow

    - by JeffreyABecker
    I have a one-time process (hashing all our user passwords) written using datasets. The performance needs improvement so we've profiled the application and found that increasing the 'batch size' of the update will improve performance. I also know that if I load the entire data set into memory the application will start hitting swap and slow down. The question is: how big is a System.Data.DataRow derived class? I'd like to calculate a batch size which I know won't force the application into swap.
