Comment exporter la table MYSQLdb en CSV sur Debian?

Question

Je veux exporter les tables MYSQLdb au format .csv.

J'ai essayé ceci:

connection = MySQLdb.connect(host='localhost', 
    user='***', 
    passwd='***', 
    db='database1', 
    use_unicode=True, 
    charset="utf8") 
cursor = connection.cursor() 
query = """ select * 
from example_table1 
into outfile 'MYFOLDER' 
fields terminated by ';' 
enclosed by '"' 
lines terminated by ''; 
""" 
cursor.execute(query) 
connection.commit() 
cursor.close() 

Je reçois ce message d'erreur:

Traceback (most recent call last): 
    File "mysql_export_to_csv.py", line 46, in <module> 
    cursor.execute(query) 
    File "/usr/lib/python2.7/dist-packages/MySQLdb/cursors.py", line 226, in execute 
    self.errorhandler(self, exc, value) 
    File "/usr/lib/python2.7/dist-packages/MySQLdb/connections.py", line 36, in defaulterrorhandler 
    raise errorvalue 
_mysql_exceptions.InternalError: (1, 'Can\'t create/write to file \'/usr/src/Python-2.7.13/output.csv\' (Errcode: 30 "Read-only file system")') 

Quel est le problème dans ce code? Pourquoi je ne peux pas l'exporter en .csv?

Je suggère d'essayer d'enregistrer votre dans un répertoire où vous avez sûrement des droits d'écriture comme/tmp/

Comme ceci:

connection = MySQLdb.connect(host='localhost', 
    user='***', 
    passwd='***', 
    db='database1', 
    use_unicode=True, 
    charset="utf8") 
cursor = connection.cursor() 
query = """ select * 
from example_table1 
into outfile '/tmp/myfile.csv' 
fields terminated by ';' 
enclosed by '"' 
lines terminated by '';
