I have a problem with a shell script:
I am trying to inject data from a source file containing MySQL queries into a data base. Here are the relevant lines of my shell script:
mysql -u root
source /usr/local/insert.sql;
quit;
For example I am running the file as ./insertfile and it is running smoothly but when it comes to data insertion in MySQL it is logging into MySQL using the mysql -u root command but the remaining operations (source /usr/local/insert.sql; and quit;) are not being executed. When I quit MySQL manually it tries to execute the rest of the command from my insert.sql file.
So please help me use the right shell script so that I can insert the queries from the source file.
One way to do that would be
mysql -u root --execute="source /usr/local/insert.sql; quit;"
It seems that your import hangs !
Check for lock on your database.
show processlist;
Run FLUSH TABLES to release any possible locks and then run your import command.
if source command hangs again :
Enter your myslq server
drop database insert;
create database insert
exit the mysql server and run:
mysqldump -u -p database-name < dump.sql
Thanks for your help. I have tried adding your line in my script and it was primarily giving some errors then I changed the command like below -
mysql -u root --execute="source /usr/local/insert.sql; \q"
Above line helped me to execute my command.
Thanks to all for being this much helpful.

I was given a MySQL database file that I need to restore as a database on my Windows Server 2008 machine.
I tried using MySQL Administrator, but I got the following error:
The selected file was generated by
mysqldump and cannot be restored by
this application.
How do I get this working?
If the database you want to restore doesn't already exist, you need to create it first.
On the command-line, if you're in the same directory that contains the dumped file, use these commands (with appropriate substitutions):
C:\> mysql -u root -p
mysql> create database mydb;
mysql> use mydb;
mysql> source db_backup.dump;
It should be as simple as running this:
mysql -u <user> -p < db_backup.dump
If the dump is of a single database you may have to add a line at the top of the file:
USE <database-name-here>;
If it was a dump of many databases, the use statements are already in there.
To run these commands, open up a command prompt (in Windows) and cd to the directory where the mysql.exe executable is (you may have to look around a bit for it, it'll depend on how you installed mysql, i.e. standalone or as part of a package like WAMP). Once you're in that directory, you should be able to just type the command as I have it above.
You simply need to run this:
mysql -p -u[user] [database] < db_backup.dump
If the dump contains multiple databases you should omit the database name:
mysql -p -u[user] < db_backup.dump
To run these commands, open up a command prompt (in Windows) and cd to the directory where the mysql.exe executable is (you may have to look around a bit for it, it'll depend on how you installed mysql, i.e. standalone or as part of a package like WAMP). Once you're in that directory, you should be able to just type the command.
mysql -u username -p -h localhost DATA-BASE-NAME < data.sql
look here - step 3: this way you dont need the USE statement
When we make a dump file with mysqldump, what it contains is a big SQL script for recreating the databse contents. So we restore it by using starting up MySQL’s command-line client:
mysql -uroot -p
(where root is our admin user name for MySQL), and once connected to the database we need commands to create the database and read the file in to it:
create database new_db;
use new_db;
\. dumpfile.sql
Details will vary according to which options were used when creating the dump file.
Run the command to enter into the DB
# mysql -u root -p
Enter the password for the user Then Create a New DB
mysql> create database MynewDB;
mysql> exit
And make exit.Afetr that.Run this Command
# mysql -u root -p MynewDB < MynewDB.sql
Then enter into the db and type
mysql> show databases;
mysql> use MynewDB;
mysql> show tables;
mysql> exit
Thats it ........ Your dump will be restored from one DB to another DB
Or else there is an Alternate way for dump restore
# mysql -u root -p
Then enter into the db and type
mysql> create database MynewDB;
mysql> show databases;
mysql> use MynewDB;
mysql> source MynewDB.sql;
mysql> show tables;
mysql> exit
If you want to view the progress of the dump try this:
pv -i 1 -p -t -e /path/to/sql/dump | mysql -u USERNAME -p DATABASE_NAME
You'll of course need 'pv' installed. This command works only on *nix.
I got it to work following these steps…
Open MySQL Administrator and connect to server
Select "Catalogs" on the left
Right click in the lower-left box and choose "Create New Schema"

Change directory to MySQL installation folder
Execute command:

…where "root" is the name of the user, "dbn" is the database name, and "C:\dbn_20080912.dump" is the path/filename of the mysqldump .dump file

As a specific example of a previous answer:
I needed to restore a backup so I could import/migrate it into SQL Server. I installed MySql only, but did not register it as a service or add it to my path as I don't have the need to keep it running.
I used windows explorer to put my dump file in C:\code\dump.sql. Then opened MySql from the start menu item. Created the DB, then ran the source command with the full path like so:
mysql> create database temp
mysql> use temp
mysql> source c:\code\dump.sql
You can try SQLyog 'Execute SQL script' tool to import sql/dump files.
Using a 200MB dump file created on Linux to restore on Windows w/ mysql 5.5 , I had more success with the
source file.sql
approach from the mysql prompt than with the
mysql < file.sql
approach on the command line, that caused some Error 2006 "server has gone away" (on windows)
Weirdly, the service created during (mysql) install refers to a my.ini file that did not exist. I copied the "large" example file to my.ini
which I already had modified with the advised increases.
My values are
[mysqld]
max_allowed_packet = 64M
interactive_timeout = 250
wait_timeout = 250
./mysql -u <username> -p <password> -h <host-name like localhost> <database-name> < db_dump-file
You cannot use the Restore menu in MySQL Admin if the backup / dump wasn't created from there. It's worth a shot though. If you choose to "ignore errors" with the checkbox for that, it will say it completed successfully, although it clearly exits with only a fraction of rows imported...this is with a dump, mind you.
One-liner command to restore the generated SQL from mysqldump
mysql -u <username> -p<password> -e "source <path to sql file>;"
Assuming you already have the blank database created, you can also restore a database from the command line like this:
mysql databasename < backup.sql
You can also use the restore menu in MySQL Administrator. You just have to open the back-up file, and then click the restore button.
If you are already inside mysql prompt and assume your dump file dump.sql, then we can also use command as below to restore the dump
mysql> \. dump.sql
If your dump size is larger set max_allowed_packet value to higher. Setting this value will help you to faster restoring of dump.
How to Restore MySQL Database with MySQLWorkbench
You can run the drop and create commands in a query tab.
Drop the Schema if it Currently Exists
DROP DATABASE `your_db_name`;
Create a New Schema
CREATE SCHEMA `your_db_name`;
Open Your Dump File
Click the Open an SQL script in a new query tab icon and choose your db dump file.
Then Click Run SQL Script...
It will then let you preview the first lines of the SQL dump script.
You will then choose the Default Schema Name
Next choose the Default Character Set utf8 is normally a safe bet, but you may be able to discern it from looking at the preview lines for something like character_set.
Click Run

Local mysql:

I am learning how to use mysql with Cloud9, I have a script used to create a default database and tables and loading sample data into the new database. How do I use the mysql-ctl tool to execute a script file?
It connects to a database just fine and I can execute ad-hoc queries without an issue.
You cannot use mysql-ctl to execute the script (you can see the source code running less $(which mysql-ctl) but you can use the usual mysql client command:
mysql -h 127.0.0.1 -u username < yourfile.sql
When you are in 'mysql-ctl' just run
source file_name.sql and your script will run.
I created a data base using mysql. I used MySQLDump to create one database backup file in text format (MySql 5.5 on Windows XP). The database is local on my machine (local host).
I am having trouble using the MySQL command to load the dump file to restore the database. I have done the following:
Research stack overflow for how to do it. I noticed there's a bug using the MySQL command to restore the data from a post. Before I run the command, I DROP the database and CREATE the database using MySQL workbench.
I type the following command in the DOS prompt to restore the database:
mysql -u root -p -h localhost -D matlab_data -o < backup.sql
backup.sql is a the backup file in text format created by MySqlDump.
I am then asked for the password which I enter. I get the DOS prompt right away with no error message. I've waited several hours for the command to run and the database is still empty.
I have tried various command formats over the last few days. If I enter incorrect data in the command line (non existen file, database, etc), I get an error message.
I feel I would not see the DOS prompt until the database is restored. If I don't DROP and CREATE the database, I get an error message. Otherwise, not.
Does anybody have any idea what the issue is? I realize that I could be making a stupid mistake.
Thank you for your help.
shell into the mysql console and run the sql file as this
If you are already running mysql, you can execute an SQL script file using the source command or . command:
mysql> source file_name
mysql> \. file_name
note that file_name must be an absolut path
I am trying to create a batch script that would connect to a mySQL database and issue a delete command:
#echo off
echo Resetting all assessments...
mysql -hlocalhost -urdfdev -p%1 rdf_feedback
delete from competency_question_answer;
I will run this script providing the password as a command-line argument, but all this script does is, connects to the database, and the mysql> prompt will be shown. After I exit from mysql, the rest of the batch commands get to execute (and fail, no surprise).
How can I pass the SQL commands from the batch script to the mysql console? Is this even possible?
You need to use command line tools. I don't know if there exists any for MySQL but for SQL there is SQLCMD and for Oracle there is OSQL.
What you can also do is something like this.
mysql -uuser -ppass < foo.sql
Where foo.sql is the commands you want to execute.
You may need to connect multiple times:
#echo off
echo Resetting all assessments...
mysql -hlocalhost -urdfdev -p%1 rdf_feedback -e delete from competency_question_answer;
Alternatively, you should be able to put all your commands in a separate file such as input.sql and use:
mysql -hlocalhost -urdfdev -p%1 rdf_feedback <input.sql
echo "delete from competency_question_answer;" | mysql -hlocalhost -ur... etc.
Putting multiple sets of commands into .sql batch files works best, and you can execute multiples of these in the .bat file.
