I am looking for the syntax for dumping all data in my mysql database. I don't want any table information.
mysqldump --no-create-info ...
Also you may use:
--skip-triggers: if you are using triggers
--no-create-db: if you are using --databases ... option
--compact: if you want to get rid of extra comments
This should work:
# To export to file (data only)
mysqldump -u [user] -p[pass] --no-create-info mydb > mydb.sql
# To export to file (structure only)
mysqldump -u [user] -p[pass] --no-data mydb > mydb.sql
# To import to database
mysql -u [user] -p[pass] mydb < mydb.sql
NOTE: there's no space between -p & [pass]
If you just want the INSERT queries, use the following:
mysqldump --skip-triggers --compact --no-create-info
>> man -k mysqldump [enter in the terminal]
you will find the below explanation
--no-create-info, -t
Do not write CREATE TABLE statements that re-create each dumped table.
Note This option does not not exclude statements creating log file
groups or tablespaces from mysqldump output; however, you can use the
--no-tablespaces option for this purpose.
--no-data, -d
Do not write any table row information (that is, do not dump table
contents). This is useful if you want to dump only the CREATE TABLE
statement for the table (for example, to create an empty copy of the
table by loading the dump file).
# To export to file (data only)
mysqldump -t -u [user] -p[pass] -t mydb > mydb_data.sql
# To export to file (structure only)
mysqldump -d -u [user] -p[pass] -d mydb > mydb_structure.sql
Best to dump to a compressed file
mysqldump --no-create-info -u username -hhostname -p dbname | gzip > /backupsql.gz
and to restore using pv apt-get install pv to monitor progress
pv backupsql.gz | gunzip | mysql -uusername -hhostip -p dbname
Would suggest using the following snippet. Works fine even with huge tables (otherwise you'd open dump in editor and strip unneeded stuff, right? ;)
mysqldump --no-create-info --skip-triggers --extended-insert --lock-tables --quick DB TABLE > dump.sql
At least mysql 5.x required, but who runs old stuff nowadays.. :)
Just dump the data in delimited-text format.
Try to dump to a delimited file.
mysqldump -u [username] -p -t -T/path/to/directory [database] --fields-enclosed-by=\" --fields-terminated-by=,
When attempting to export data using the accepted answer I got an error:
ERROR 1235 (42000) at line 3367: This version of MySQL doesn't yet support 'multiple triggers with the same action time and event for one table'
As mentioned above:
mysqldump --no-create-info
Will export the data but it will also export the create trigger statements. If like me your outputting database structure (which also includes triggers) with one command and then using the above command to get the data you should also use '--skip-triggers'.
So if you want JUST the data:
mysqldump --no-create-info --skip-triggers

I am trying to take mysql dump with command:
mysqldump -u xxxx -p dbxxx > xxxx270613.sql
what is command to take mysqldump with UTF8 ?
Hi please try the following.
mysqldump -u [username] –p[password] --default-character-set=utf8 -N --routines --skip-triggers --databases [database_name] > [dump_file.sql]
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
i want to move mysql database tables which resides in one computer to another computer. how can i create dump file as we created in Oracle ?
i m using exp command but not working.
Use mysqldump.
mysqldump -u <username> -p<password> <db_name> > <filename>.sql
To import, create empty database named <db_name>, thena -
mysql -u <username> -p<password> <db_name> < <filename>.sql
To export all databases -
mysqldump -u <username> -p<password> --all-databases > <filename>.sql
mysqldump -u <username> -p<password> -h <hostname> <dbname> <tablename> > filename.sql
Now you may need to take the dump of just the schema. For example you use a command called like.
mysql> show create table tablename;
this will give you the query that created the table. Now for some reason you need to take schema dump of all the tables inside you database/databases you may use -d option like this
mysqldump -d -u <username> -p<password> -h <hostname> <dbname> > filename.sql
The -d option means "without data".
Now you have full dump without the data and just the schema.
here is the command I'm using:
mysqldump.exe -u root -d capstone -verbse --skip-quote-names > capstone.sql
and the output I get
mysqldump: Warning: Can't set SQL_QUOTE_SHOW_CREATE option ()
-- Skipping dump data for table 'users', --no-data was used
any ideas? if I dump to XML it works but the place I'm importing it to doesn't handle XML and my data ruins the CSV output somehow too.
the -d option is alias of --no-data, see https://dev.mysql.com/doc/refman/5.7/en/mysqldump.html#option_mysqldump_no-data
perhaps you intended to state "use database capstone" but in that case it wouldn't be -d capstone, the database name doesn't need any switch/option, just put it in there
shell> mysqldump [options] db_name [tbl_name ...]
shell> mysqldump [options] --databases db_name ...
shell> mysqldump [options] --all-databases
https://dev.mysql.com/doc/refman/5.7/en/mysqldump.html#mysqldump-syntax
I think you mean to use either -B / --databases (which includes allows you to indicate multiple databases to dump instead of a database and tables) or no such argument at all. I think you also mistyped --verbose.
Note that if you include --databases a CREATE DATABASE statement is also included. This could be important depending up on how you intend to use the data.
I want to dump mysql database only the tables which have data, Can u please give me your suggestion. this is more helpful
Thanks & Regards,
Vara Kumar.PJD
You can use the --ignore-table option, but you have to find out which tables are empty first as this is not directly possible with mysqldump. So you could do
mysqldump -u username -p database --ignore-table=database.table1 --ignore-table=database.table2 > database.sql
mysqldump <database options> table1 table2 table3 ...
Use mysqldump (documentation located here). If you do not specify tables it assumes all tables. You can also explicitly choose tables to copy or to ignore. You can tell it to create drop statements before your create statements. If you have mysql 5.1.2 then you can tell it to copy routines.
When you are dumping all database. Obviously it is having large data. So you can prefer below for better:
Creating Backup:
mysqldump -u [user] -p[password]--single-transaction --quick --all-databases | gzip > alldb.sql.gz
If error
-- Warning: Skipping the data of table mysql.event. Specify the --events option explicitly.
Use:
mysqldump -u [user] -p --events --single-transaction --quick --all-databases | gzip > alldb.sql.gz
Restoring Backup:
gunzip < alldb.sql.gz | mysql -u [user] -p[password]
Hope it will help :)
following is the that I create dump from mysql database.
mysqldump -u root tempbkk > ttt.dump
but I want to create a dump that exclude one or more file while creating dump from database we select.What is the command for that ?
mysqldump -u user -p some_database > some_database_dump.sql
mysqldump can skip tables, you need the --ignore-table parameter. Check out the manual of mysqldump.
mysqldump -u <user> -p<password> --databases <dbname> -r <NameofBackup.sql>
Simply type this command mysqldump -u user -p database_name_in_database > name_of_file.sql
it will ask password for user. and there you go, your dumb file is ready. on same the location from where you run the command
