Loading utf-8 encoded text into MySQL table
I have a large CSV file that I am going to load it into a MySQL table. How开发者_如何学Cever, these data are encoded into utf-8 format, because they include some non-english characters. I have already set the character set of the corresponding column in the table to utf-8. But when I load my file. the non-english characters turn into weird characters(when I do a select on my table rows). Do I need to encode my data before I load the into the table? if yes how Can I do this. I am using Python to load the data and using LOAD DATA LOCAL INFILE command. thanks
Try
LOAD DATA INFILE 'file'
IGNORE INTO TABLE table
CHARACTER SET UTF8
FIELDS TERMINATED BY ';'
OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n'
as said in http://dev.mysql.com/doc/refman/5.1/en/load-data.html, you can specify the charset used by your CSV file with the "CHARACTER SET" optional parameter of LOAD DATA LOCAL INFILE
Do not need encode your characters in the file, but you need to make sure that your file is encoding at UTF-8 before load this file to database.
You should send
init_command = 'SET NAMES UTF8'
use_unicode = True
charset = 'utf8'
when doing MySQLdb.connect() e.g.
dbconfig = {}
dbconfig['host'] = 'localhost'
dbconfig['user'] = ''
dbconfig['passwd'] = ''
dbconfig['db'] = ''
dbconfig['init_command'] = 'SET NAMES UTF8'
dbconfig['use_unicode'] = True
dbconfig['charset'] = 'utf8'
conn = MySQLdb.connect(**dbconfig)
edit: ah, sorry, I see you've added that you're using "LOAD DATA LOCAL INFILE" -- this wasn't clear from your initial question :)
Try something like,
LOAD DATA LOCAL INFILE "file" INTO TABLE message_history CHARACTER SET UTF8 COLUMNS TERMINATED BY '|' OPTIONALLY ENCLOSED BY '"' ESCAPED BY '"';
