How take mysqldump with UTF8? - mysql

Question

I am trying to take mysql dump with command:
mysqldump -u xxxx -p dbxxx > xxxx270613.sql
what is command to take mysqldump with UTF8 ?

Answer 1

Hi please try the following.
mysqldump -u [username] –p[password] --default-character-set=utf8 -N --routines --skip-triggers --databases [database_name] > [dump_file.sql]

Answer 2

I had the problem, that even with applied utf-8 flags when creating the dump I could not avoid broken characters importing a dump that was created from a DB with many text columns using latin1.
Some googling and especially this site helped me to finally figure it out.
mysqldump with --skip-set-charset --default-character-set=latin1 flags,
to avoid MySQL attempt of reconversion and setting a charset.
fix the dump by replacing the charset strings using sed on terminal
sed -i 's/latin1_swedish_ci/utf8mb4/g' mysqlfile.sql
sed -i 's/latin1/utf8mb4/g' mysqlfile.sql
to make sure you don't miss anything you can do grep -i 'latin1' mysqlfile.sql before step 2 - and then come up with more sed orders. Introduction to sed here
create a clean DB
CREATE DATABASE mydatabase CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci;
apply fixed dump

--default-character-set=utf8 is the option you are looking for the one can be used together with these others:
mysqldump --events \
--routines \
--triggers \
--add-drop-database \
--compress \
--hex-blob \
--opt \
--skip-comments \
--single-transaction \
--skip-set-charset \
--default-character-set=utf8 \
--databases dbname > my.dump
Also, check the --hex-blob it helps to dump binary strings in hexadecimal format, so I can guaranty (be more portable) making the import to work.
The --databases option causes all names on the command line to be treated as database names. Without this option, mysqldump treats the first name as a database name and those following as table names.
With --all-databases or --databases, mysqldump writes CREATE DATABASE and USE statements prior to the dump output for each database. This ensures that when the dump file is reloaded, it creates each database if it does not exist and makes it the default database so database contents are loaded into the same database from which they came. If you want to cause the dump file to force a drop of each database before recreating it, use the --add-drop-database option as well. In this case, mysqldump writes a DROP DATABASE statement preceding each CREATE DATABASE statement.
This helps to restore using:
# mysql < dump.sql
Instead of:
# mysql dbname < dump.sql
