I am writng the data returned from paypal into a csv file and then load this csv file into mysql database.
Part of data returned from Paypal : %f0%9f%98%9d%2e
Which i then decode using decodeuricomponent to 😠.
when i save this to file and do load data in file it gives mysql error:
Invalid utf8 character string
The load data in file query is:
LOAD DATA LOCAL INFILE 'note.csv' REPLACE INTO TABLE table1 CHARACTER SET UTF8 FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\n' (note)
The collation of database, table and columns is utf_general_ci
So i tried encoding the data returned from paypal using
utf8.encode("😠.")
And then saved it to file. But it was not encoded correctly.
After this the load data in file didn't return any error but the data saved in column was ð. Which is incorrect.
How do i correctly encode the string so that it can be loaded into the table.
Link to files:
http://speedy.sh/RMu5M/note.csv (encoded)
http://speedy.sh/ajrQj/notenonencoded.csv (nonencoded)
For 😝 (hex f09f989d), you need MySQL's utf8mb4, not utf8. Use that in the table and in the connection.

I receive a data file in ETL from the client and we load the data into Mysql database using Load Data file functionality and use CHARACTER SET
as utf8.
LOAD DATA LOCAL INFILE '${filePath}'
INTO TABLE test_staging
CHARACTER SET 'utf8'
FIELDS TERMINATED BY '|'
LINES TERMINATED BY '\n'
(${testcolumns}) SET
first_name = #first_name;
Data from client
1|"test"|"name"|2
2|"asdf"|asdf&test|2
3|fun|value|2
When I load the above data into the database and it is inserting directly as strings instead of converting to html characters
Database Data
id first_name last_name
1 "test" "name"
2 "asdf" asdf&test
3 fun value
I tried changing the CHARACTER SET value from utf8 to latin1 but the result is same.
I also tried replacing the special characters while loading the data into database but the issue is, I receive all types of html characters data in the file. I cannot keep on adding the replace function for all of them.
LOAD DATA LOCAL INFILE '${filePath}'
INTO TABLE test_staging
CHARACTER SET 'utf8'
FIELDS TERMINATED BY '|'
LINES TERMINATED BY '\n'
(${testcolumns}) SET
first_name = REPLACE(REPLACE(REPLACE(first_name,''','\''),'"','"'),'&','&');
Is there any character set which converts the html data and loads correctly?
Expected Database Data
id first_name last_name
1 "test" "name"
2 "asdf" asdf&test
3 fun value
Any help is appreciated... Thanks
The problem you are facing is not about character set. It happens because the software that your client use intentionally converts HTML special characters to their codes.
It is probably possible to convert them back using MySQL though I couldn't find a quick solution, but as you are handling this data with ETL the better option seems to be to use the external tool before you insert the data into the database. One of these for example:
cat input-with-specialchars.html | recode html..ascii
xmlstarlet unesc
perl -MHTML::Entities -pe 'decode_entities($_);'
etc.
or something else depending on what tools you have available in your system or which ones you can afford to install.
I have to migrate a database from Oracle to MySql having billions of data. I found a strategy to create a schema and get the data in CSV from Oracle and load data to MySQL. I have created a CSV file with a delimiter of a quote(") and field terminated with a comma(,). Now the problem is that CSV file contains special character which is not going to be imported in MySql.
I am using the command:
LOAD DATA LOCAL infile 'C:/Users/NNCP4659/export.csv' INTO TABLE dbk_address_master
CHARACTER SET utf8 fields terminated BY "," enclosed by '"' lines terminated
BY "\r\n"(id, country_code,address,city_id,latitude,longitude,
#is_active,google_address,old_address,building_number,street_name,created_by)
set is_active=cast(#is_active as signed);
My data is like:
4113973,"CHE","167 Bernerstrasse Süd","57066","47.3943271","8.4865849",1,"Bernerstrasse Süd 167, 8048 Zürich,
Switzerland","167 Bernerstrasse Süd","Y","167","Bernerstrasse Süd","migration"
And error is:
ERROR 1300 (HY000): Invalid utf8 character string: '"167
Bernerstrasse S'
167 Bernerstrasse S looks like the truncation of 167 Bernerstrasse Süd at the first non-utf8 character.
You have specified that the incoming data is utf8 via
LOAD DATA ... CHARACTER SET utf8 ...
I conclude that the incoming file is not encoded correctly. It is probably latin1, in which case the hex would be FC. Assuming this is the case, you should switch to
LOAD DATA ... CHARACTER SET latin1 ...
It does not matter if the CHARACTER SET in the target column is not latin1; MySQL will transcode it in flight.
(Alternatively, you could change the incoming data to have utf8 (hex: C3BC), but that may be more hassle.)
Reference: "truncated" in Trouble with UTF-8 characters; what I see is not what I stored
(As for how to check the hex, or do SHOW CREATE TABLE, we need to know what OS you are using and what tools you have available.)
I am trying to import a CSV file into MySQL via the command line with following command :
USE database
LOAD DATA LOCAL INFILE 'C:/TEMP/filename.csv' INTO TABLE tablename
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n';
But when I do that, the system will truncate all the data of some columns to a length of 10 characters. I have tried using the CHARACTER SET option (UTF8, LATIN1), but that did not help. I've also tried to save the initial CSV file differently.
An example of such data item in such column would be "+00000000000#abc.de.fg;abdc=apcde,abcdefghijklmnop#qrs.tu.vw" which will be truncated to +000000000 , sometimes when there is no number it will be truncated to "abc#vgtw.c" or similar.
How do I get the data to be imported without truncating anything, and have the data imported as is ?
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 have a large CSV file that I am going to load it into a MySQL table. However, 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 '"';
