Selecting data from mysql using qt?


  • Change the 19th line to

    @QSqlQuery query(db);@

    0

  • same error again

    0

  • Take a look into mysql logs to see what happens when you are trying to connect from your application.

    0

  • how can i check that mysql logs and from where?

  • [quote author="doforumda" date="1286880547"]how can i check that mysql logs and from where? [/quote]

    Try to find them:
    @find /opt/lampp -name log -type d@

    When you find the log directory, find a log for mysql and use tail utility:

    @tail -f /path/to/mysql.log@

    0

  • this command didnt return something
    @
    root@zafar-laptop:/# find /opt/lampp -name log -type d
    root@zafar-laptop:/#
    @

  • i have a folder inside lampp with the name logs. is it the one which your are talking about

    0

  • Solution 1:
    @find /opt/lampp -name '*.log'@
    This might need sudo'ing.

    Solution 2:
    If 1st fails then you need to find the config files for mysql (it should be located in /opt/lampp directory) and try to find out what is the location of mysql's log files.

    0

  • there are 6 files in there but no mysql.log

    these are the files
    access_log, cgisock.1693, error_log, httpd.pid, php_error_log, ssl_request_log

    0

  • Don't bother with the log files, I guess Qt looks at the wrong place for the socket file...

    Let's check this line in your mysql config file (my.cnf):

    socket = /var/run/mysqld/mysqld.sock

    You should find my.cnf in /etc/ or /etc/mysql/ ... I don't know ubuntu that much.

    0

  • 1st solution returns this
    @
    root@zafar-laptop:/# find /opt/lampp -name *.log
    /opt/lampp/htdocs/xampp/contrib/sqlnet.log
    @

    0

  • with which editor i can view that .conf file. with gedit or something.

  • [quote author="¤ Dii ¤" date="1286881470"]
    You should find my.cnf in /etc/ or /etc/mysql/ ... I don't know ubuntu that much.[/quote]

    I don't think that this config will be in /etc. He uses lampp - a preconfigured bundle. That config might be in /opt/lampp.

    0

  • BTW a quick sum:

    • mysql is installed
    • database and tables are created
    • access is granted
    • qt code looks fine

    I see two possibilities here: libmysqlclient is missing, or the socket file is at different place.

    0

  • the file my.cnf is in etc/mysql folder

    0

  • doforumda: use gedit

    sudo gedit /etc/mysql/my.cnf

    at least most of the ubuntu machines have the config file there.

    0

  • this is the socket line in my.cnf

    @
    socket = /var/run/mysqld/mysqld.sock
    @

    0

  • ok then the wrong socket guess was wrong... but let's make it sure:

    sudo ls -l /var/run/mysqld/*

    0

  • after running this sudo ls -l /var/run/mysqld/* there is nothing inside run directory

    0

  • uhmmmmmmm that's more than strange, the socket file should be there somewhere, let's find it:

    find /var -name mysqld.sock

    if no result:

    find /opt -name mysqld.sock

    0

  • both of them didnt return any resutl

    @
    root@zafar-laptop:/# find /var -name mysqld.sock
    root@zafar-laptop:/# find /opt -name mysqld.sock
    root@zafar-laptop:/#
    @

    0

  • I have bitnami lampp stack installed and when I start it then the socket file is created in /opt/lamppstack/mysql/tmp/mysql.sock. I think doforumda shoudl have similar directory and we need to check the permissions for that directory.

    0

  • Usually that means, that the mysql daemon is not running... but the the command line should not work as well... ;(

    It doesn't hurt to try to start the daemon:

    sudo /etc/init.d/mysql start

    ... and do the search for the socket file as above.

    0

  • gosh, do the find with sudo:

    sudo find /opt -name mysqld.sock
    sudo find /var -name mysqld.sock

    damn, I always forget that with ubuntu

    0

  • lyuts: yes, if he have the socket file at the same place, we need to symlink it to the /var/... location and happy end :) I hope so.

    0

  • tyut: yes i have one file with the name of mysql.sock in /opt/lampp/var/mysql/mysql.sock

    0

  • the permissions on mysql.sock it read write exe for all types of users

    0

  • Great, don't give up, we are close :D

    ls -l /opt/lampp/var/mysql/*

    maybe you have another mysql config file somewhere:

    ls -l /opt/lampp/etc/my.cnf
    or
    ls -l /opt/lampp/etc/mysql/my.cnf
    ?

    0

  • gosh... all with sudo please

    0

  • i got this output from this command sudo ls -l /opt/lampp/var/mysql/*

    the output is too long so i am posting it in pieces

  • ok doforumda, that's enough... I want to make it sure, can you check, the
    sudo ls -l /opt/lampp/etc/my.cnf
    or
    sudo ls -l /opt/lampp/etc/mysql/my.cnf
    ?
    If one of them is there, let's take a look with gedit, for the
    socket = /something
    part?

    0

  • ok, then
    sudo gedit /opt/lamp/etc/my.cnf

    look for the socket = something line

  • ¤ Dii ¤, maybe this would be easier?

    @sudo find /opt/lampp -name my.cnf -type f | xargs grep -n socket@

  • Dii: i use this command sudo gedit /opt/lamp/etc/my.cnf but unfortunately the file is empty. there is nothing in it.

    lyut: your command sudo find /opt/lampp -name my.cnf -type f | xargs grep -n socket

    displays this
    @
    root@zafar-laptop:/# sudo find /opt/lampp -name my.cnf -type f | xargs
    /opt/lampp/etc/my.cnf
