I have a MySQL DB, which should be exported in the CSV file. Google told me about so many examples to do this, but all the examples are for exporting only one table.

Can someone help export some data (given below) in a particular way?

  • The album

    the artist

  • Name
  • Name

    Title

    • ID
    • artist_id
    • Name < / Li>

      There are FK fields in the title, which point to artist name and album name. P>

      3 (title)

      John latest, first song
      John, work on progress, good song
      John, California, Oh SF - Luke, Mai songs, a song
      Luke, my songs, two Songs
      Luke, Archived Tom, My Works, Second Song - Tom, My Works, III Songs

      TIA

      You can create a view and export from there.

      Expand Mahesh's query: 

        View View View as Visual Editor, name as artist_name, album.name as album_name, title.name AS Title , Titled Artist, Album, Title WHERE artist.id = title.artist_id and album.id = title.album_id; SELECT * FROM 'OUTFILE' example_output.csv 'FIELDS defined by FIELDS' in 'view_example', ';   
       I tested it and it works.

    I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

    mongodb - CakePHP paginator ignoring order, but only for certain values -

    While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
