I have a mySQL database full of accented characters. The DB is populated periodically from MS Access 2010.
In Access you'll see é è à Ü. In the export process in Access UTF-8 encoding is specified.
Open the resulting text file in UltraEdit on my PC and you'll see "Vieux Carré" and UE says the encoding is U8-DOS.
The files are uploaded via FTP and imported via LOAD DATA LOCAL INFILE queries like this
LOAD DATA LOCAL INFILE '$dir/$t.$ext' INTO TABLE `$t` FIELDS OPTIONALLY ENCLOSED BY '|' TERMINATED BY ';' LINES TERMINATED BY '\n'
In mySQL the field collation is set to utf8_general_ci.
If you query mySQL from the command line or from phpMyAdmin you'll see "Vieux Carré".
What am I doing wrong?
If you're using LOAD DATA INFILE with a file that has a charset that's different from your database's default, you need to specify what character set the file is in:
LOAD DATA LOCAL INFILE '$dir/$t.$ext'
INTO TABLE `$t`
CHARACTER SET utf8
FIELDS OPTIONALLY ENCLOSED BY '|' TERMINATED BY ';'
LINES TERMINATED BY '\n'
Note that the database character set is database-wide, and is different than the table character set and the column character set. SHOW CREATE DATABASE database_name will show you the database charset.

I'm trying to import a file into a MySql database using query below. The fields in the file are delimited by '¦' (broken vertical bar) U+00A6.
I'm executing the query from PhpMyAdmin
LOAD DATA LOCAL INFILE "/path/filename.csv" INTO TABLE tablename
CHARACTER SET 'UTF8'
FIELDS TERMINATED BY '¦'
Somehow mysql ignores the field separator and loads all records into the first field of the table
You can represent it like X'A6'
LOAD DATA LOCAL INFILE "/path/filename.csv" INTO TABLE tablename
CHARACTER SET 'UTF8'
FIELDS TERMINATED BY X'A6'
SET NAMES utf8; -- You were probably missing this (or the equivalent)
LOAD DATA LOCAL INFILE "/path/filename.csv" INTO TABLE tablename
CHARACTER SET 'UTF8'
FIELDS TERMINATED BY '¦'
(assuming you can type ¦ in utf8, not latin1)
The clue was "Â" gibrish character at the end of every sting, together with ¦ mojibaked becomes ¦.
The source document is probably encoded in unwanted characters, such as what Excel does. Try opening and saving in TextEdit, or another bare bones text editor, making sure the data is saved as UTF-8. Then:
LOAD DATA LOCAL INFILE "filepath/file.csv" INTO TABLE `table`
CHARACTER SET 'utf8'
FIELDS TERMINATED BY '\¦';
With escape character before broken bar. Also use UTF-8 Unicode encoding on the entire table, not just the rows.
I want to import an .xlsx file with ~60k rows to MySQL. Some columns contain Vietnamese characters. I managed to convert from .xlsx to .csv without messing up the character set. However I can't do the same when importing .csv to MySQL.
I used LOAD DATA INFILE. It looks something like this:
LOAD DATA LOCAL INFILE 'c:/Projekt/Big Data/events.csv'
INTO TABLE database.table
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 LINES;
(Source: http://blog.habrador.com/2013/01/how-to-import-large-csv-file-into-mysql.html)
This method imports the data fine but the character set of Vietnamese characters are totally messed up. I did change table's collation to utf8_unicode_ci.
I also test the traditional import method of MySQL with smaller datasets and it preserves the font perfectly. However I cannot use it since my file's size exceeds the limit of MySQL.
Really appreciate if someone could help me with this.
Try to explicit character set specify by import:
LOAD DATA LOCAL INFILE 'c:/Projekt/Big Data/events.csv'
INTO TABLE database.table
CHARACTER SET utf8
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 LINES;
See docs for more details about loading from file.
Im having problems with LOAD DATA LOCAL INFILE loading a utf8 file.
The Query looks like this:
LOAD DATA LOCAL INFILE 'file.csv' INTO TABLE artikel CHARACTER SET UTF8
FIELDS TERMINATED BY ';' ENCLOSED BY '"' LINES TERMINATED BY '\r\n';
But fields with special characters like "Dämmung" will be cut to "D".
SHOW VARIABLES LIKE '%_set_%';
Shows that it's all set to utf8, and I even used notepad++ to make sure the file is utf8.
It would really help, if someone knows advice, it's a huge file and I would like to avoid entering the wrong fields manually :-/
I was having the same problem.
There is a "hack" that solves this: maitain everything with UTF8. The exception is with the "LOAD DATA LOCAL....". When I use LATIN1 instead of UTF8 it works fine.
It worked for me.
LOAD DATA LOCAL INFILE 'D:/File.csv'
INTO TABLE my_table
CHARACTER SET latin1
FIELDS TERMINATED BY ';'
OPTIONALLY ENCLOSED BY '"'
ESCAPED BY '\\'
LINES TERMINATED BY '\r\n'
Unfortunately, LOAD DATA does not accept utf8 input, no matter what charset is passed on cli options and used by the table. I didn't find it in documentation and assume it is a bug.
The workaround is to use mysqlimport instead. The shortcoming of this solution is that if you want to disable foreign key check during import (doesn't apply to MyISAM tables) you will have to disable it globally, which requires SUPER privilege:
echo "SET GLOBAL FOREIGN_KEY_CHECKS=0;" | mysql -u root -p
Here is my solution when I was troubleshooting this problem of a special characters:
I will explain:
you can change ; to , because I used csv ; separated not like you
I had line breaks inside my columns so I escaped with \\
The script is :
LOAD DATA LOCAL INFILE 'D:/File.csv'
INTO TABLE my_table
CHARACTER SET latin1
FIELDS TERMINATED BY ';'
OPTIONALLY ENCLOSED BY '"'
ESCAPED BY '\\'
LINES TERMINATED BY '\r\n'
Please take care about the collation type of the database and table columns!
I'm using the utf8mb4_unicode_520_ci for both database and table columns.
Everything worked well with keeping CHARACTER SET utf8 in the query.
I have a file.csv with 300,000 rows. Many of the rows are the names of foreign cities with accented characters. When I try to do an import in mysql, I get warnings on the fields, and it truncates the field at the point of the special character.
LOAD DATA LOCAL INFILE '/var/tmp/geoip/location.csv' INTO TABLE Geolocation2 FIELDS TERMINATED BY ',' enclosed by '"' LINES TERMINATED BY '\n' (id, country, region, city, postalCode, latitude, longitude, metrocode, areacode );
I had this problem with CSV files created by MS Excel. If you are using Excel, or need to convert CSV files to UTF-8 for importing into MySQL the answer here may be of help.
Open and SaveAs all your SQL Query and Data Files with UTF-8 encoding
This will solve BULK INSERT problems
use option WITH (DATAFILETYPE = 'widenative')
It will also solve INSERT INTO Problems whether the data is in the same file as the CREATE TABLE instruction or chained :r "X:\Path\InsertIntoMyTable.sql"
You need to set the connection, database, table and column encodings to the same character set as the data was saved in the CSV file.
http://dev.mysql.com/doc/refman/5.0/en/charset.html
This sequence works to me.
create database {$databasename} DEFAULT CHARACTER SET latin1;
ALTER DATABASE {$databasename} DEFAULT CHARACTER SET latin1 DEFAULT COLLATE latin1_swedish_ci;
charset latin1;
load data infile '{$file.csv}' into table {$tablename} character set latin1 fields terminated by '|' enclosed by '"' lines terminated by '\n';
Tell MySQL what the codepage of the source file is when you import it. e.g. to import a file with codepage Windows-1252, use MySQL codepage latin1 (which is the same thing) like this:
LOAD DATA LOCAL INFILE '/path/to/file.csv'
INTO TABLE imported_table
CHARACTER SET 'latin1'
COLUMNS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
ESCAPED BY '"'
LINES TERMINATED BY '\r\n'
IGNORE 1 LINES;
I am trying to import a dataset with korean characters in, saved as unicode encoding using CSV LOAD DATA
even when I set the input character set to utf8 the korean get's mangled
the encoding for that column is of course utf8
sample record (tab delimited):
79 읽다 read NULL
what goes into MYSQL:
79 ì½ë‹¤ read NULL
load data supports character set clause
load data local infile 'filename.txt' into table test.unicode CHARACTER SET utf8
Use it from the command line if phpmyadmin ignores it.
It seems like phpmyadmin ignores the select drop-down, and does not append the CHARACTER SET utf8 clause to the query.
You can manually execute the query that phpMyAdmin should, however. Try this:
LOAD DATA LOCAL INFILE 'e:\\www\\wro11.csv' INTO TABLE `videos` CHARACTER SET utf8 FIELDS TERMINATED BY ';' ENCLOSED BY '"' ESCAPED BY '\\' LINES TERMINATED BY '\n'
here is an example:
LOAD DATA INFILE 'data.txt' INTO TABLE tbl_name
FIELDS TERMINATED BY ',' ENCLOSED BY '"'
LINES TERMINATED BY '\r\n'
IGNORE 1 LINES;
