I've read a post saying that I would have to use this command below, to dump my sql files
$ mysqldump -u [uname] -p db_name > db_backup.sql
However, my question is, I don't quite get where the db_backup.sql comes from. Am I suppose to create a file or is it being created as I enter any name for the backup sql?
Also, where can I find the backup.sql at?
More information: I am doing this on Mariadb/phpmyadmin on the xampp shell
Whichever directory you are in when you run that command will have db_backup.sql.
The statement:
mysqldump -u user -p db_name generates an output on the terminal screen, assuming you are SSH'ed into the server. Instead of the output written on the screen, you can redirect the output to a file.
To do that, you use > db_backup.sql after the command.
If you are in directory /home/hyunjae/backups and run the command:
$ mysqldump -u [uname] -p db_name > db_backup.sql
You will see a new file created called db_backup.sql. If there's already a file with that name, it will be overwritten.
If you don't know what directory you are in, you can type pwd for present working directory.
db_backup.sql is automatically generated by the mysqldump command, and is located in the current directory (.) by default. If you need to specify a directory, you can directly specify /path/to/target/db_backup.sql.
I would like to append date in file name when taking backup using mysqldump. I am storing the command in properties file and running it via ProcessBuilder and shell script. I have tried multiple ways to add the date (BTW all the answers here were only if we run the command directly in linux)
mysqldump -u <user> -p <database> | gzip > <backup>$(date +%Y-%m-%d-%H.%M.%S).sql.gz
Got the error: No table found for "+%Y-%m-%d-%H.%M.%S"
mysqldump -u root -ppassword dbName --result-file=/opt/backup/`date -Iminutes`.dbName.sql
Got the error: unknow option -I
Is there a way around for this to add date in the command itself? I cannot append the date in java method or shell script.
I can't tell from your question whether you're running in a shell. If so, try these three lines to generate your backup file.
DATE=`date +%Y-%m-%d-%H.%M.%S`
FILENAME=backup${DATE}.sql.gz
mysqldump -u user -p database | gzip > ${FILENAME}
Notice how you should surround the date command in the first line with backticks, not ${}, to get its result into the DATE shell variable.
I am working on Linux (Ubuntu), and I want to export the whole schema from .sh file to .sql in order to open it in MySQL Workbench - but how can I do it?
I have tried with mysqldump but it doesn't work, I wrote this command after opening .sh database, but I am not sure if it has some influence.
Command line in terminal:
mysql> mysqldump -uuser -ppassword db > db.sql
And it doesn't work - MySQL syntax error displays after that
Here .sh means a script file extension in which you will write your commands and .sql means a backup/dump file.
Example
Execute below command on linux prompt-
sudo vi backup_script.sh
It will open a blank file you can write your script here like -
cd /root/backup/
mysqldump -uroot -proot123 mydb > /root/backup/mydb.sql
Now save this file by Esc + : + wq
Note: backup folder should exist in root else you can create by below command-
mkdir /root/backup
Now you can execute backup_script.sh by below command-
sh backup_script.sh
It wil take your mydb database backup at /root/backup/ path.
1.Install mysql-client which includes mysqldump
user#local:~$ sudo apt-get install mysql-client-5.1
2. backup database
user#local:~$ mysqldump -u root -p[root_password] [database_name] > dumpfilename.sql
3. if you need you can import
user#local:~$ mysql -u root -p[root_password] [database_name] < dumpfilename.sql
I have the following batch file:
#ECHO on
cd "C:\Program Files\MariaDB\mariadb\bin"
mysql -u root < "C:\database_setup.sql"
When I run the command directly in the command line, it works fine. When I run this batch file I get that it's trying to execute:
mysql -u root 0<"C:\database_setup.sql"
To solve this, I tried to escape the less than sign with:
mysql -u root ^< "C:\database_setup.sql"
It appears to be correct in the console but it's dumping the mysql options instead of inserting the contents of database_setup.sql.
I'm thinking that this is because the "<" is actually be referred to as a string since I'm escaping it and not as the redirection operator.
How does one accomplish running this command in a batch file (which works fine directly in the console)?
The following workaround could help you:
mysql -u root -e "SOURCE C:\database_setup.sql"
Also the following should work:
type C:\database_setup.sql | mysql -u root
How can I import a database with mysql from terminal?
I cannot find the exact syntax.
Assuming you're on a Linux or Windows console:
Prompt for password:
mysql -u <username> -p <databasename> < <filename.sql>
Enter password directly (not secure):
mysql -u <username> -p<PlainPassword> <databasename> < <filename.sql>
Example:
mysql -u root -p wp_users < wp_users.sql
mysql -u root -pPassword123 wp_users < wp_users.sql

4.5.1.5. Executing SQL Statements from a Text File
Note: If you are on windows then you will have to cd (change directory) to your MySQL/bin directory inside the CMD before executing the command.
Preferable way for windows:
Open the console and start the interactive MySQL mode
use <name_of_your_database>;
source <path_of_your_.sql>
mysql -u <USERNAME> -p <DB NAME> < <dump file path>
-u - for Username
-p - to prompt the Password
Eg. mysql -u root -p mydb < /home/db_backup.sql
You can also provide password preceded by -p but for the security reasons it is not suggestible. The password will appear on the command itself rather masked.
Directly from var/www/html
mysql -u username -p database_name < /path/to/file.sql
From within mysql:
mysql> use db_name;
mysql> source backup-file.sql
Open Terminal Then
mysql -u root -p
eg:- mysql -u shabeer -p
After That Create a Database
mysql> create database "Name";
eg:- create database INVESTOR;
Then Select That New Database "INVESTOR"
mysql> USE INVESTOR;
Select the path of sql file from machine
mysql> source /home/shabeer/Desktop/new_file.sql;
Then press enter and wait for some times if it's all executed then
mysql> exit
From Terminal:
mysql -uroot -p --default-character-set=utf8 database_name </database_path/database.sql
in the terminal type
mysql -uroot -p1234; use databasename; source /path/filename.sql
Below command is working on ubuntu 16.04, I am not sure it is working or not other Linux platforms.
Export SQL file:
$ mysqldump -u [user_name] -p [database_name] > [database_name.sql]
Example : mysqldump -u root -p max_development > max_development.sql
Import SQL file:
$ mysqldump -u [user_name] -p [database_name] < [file_name.sql]
Example: mysqldump -u root -p max_production < max_development.sql
Note SQL file should exist same directory
I usually use this command to load my SQL data when divided in files with names : 000-tableA.sql, 001-tableB.sql, 002-tableC.sql.
for anyvar in *.sql; do <path to your bin>/mysql -u<username> -p<password> <database name> < $anyvar; done
Works well on OSX shell.
Explanation:
First create a database or use an existing database. In my case, I am using an existing database
Load the database by giving <name of database> = ClassicModels in my case and using the operator < give the path to the database = sakila-data.sql
By running show tables, I get the list of tables as you can see.
Note : In my case I got an error 1062, because I am trying to load the same thing again.
mysql -u username -ppassword dbname < /path/file-name.sql
example
mysql -u root -proot product < /home/myPC/Downloads/tbl_product.sql
Use this from terminal
After struggling for sometime I found the information in https://tommcfarlin.com/importing-a-large-database/
Connect to Mysql (let's use root for both username and password):
mysql -uroot -proot
Connect to the database (let's say it is called emptyDatabase (your should get a confirmation message):
connect emptyDatabase
3 Import the source code, lets say the file is called mySource.sql and it is in a folder called mySoureDb under the profile of a user called myUser:
source /Users/myUser/mySourceDB/mySource.sql
Open the MySQL Command Line Client and type in your password
Change to the database you want to use for importing the .sql file data into. Do this by typing:
USE your_database_name
Now locate the .sql file you want to execute.
If the file is located in the main local C: drive directory and the .sql script file name is currentSqlTable.sql, you would type the following:
\. C:\currentSqlTable.sql
and press Enter to execute the SQL script file.
If you are using sakila-db from mysql website,
It's very easy on the Linux platform just follow the below-mentioned steps, After downloading the zip file of sakila-db, extract it. Now you will have two files, one is sakila-schema.sql and the other one is sakila-data.sql.
Open terminal
Enter command mysql -u root -p < sakila-schema.sql
Enter command mysql -u root -p < sakila-data.sql
Now enter command mysql -u root -p and enter your password, now you have entered into mysql system with default database.
To use sakila database, use this command use sakila;
To see tables in sakila-db, use show tables command
Please take care that extracted files are present in home directory.
First connect to mysql via command line
mysql -u root -p
Enter MySQL PW
Select target DB name
use <db_name>
Select your db file for import
SET autocommit=0; source /root/<db_file>;
commit;
This should do it. (thanks for clearing)
This will work even 10GB DB can be imported successfully this way. :)
In Ubuntu, from MySQL monitor, you have already used this syntax:
mysql> use <dbname>
-> The USE statement tells MySQL to use dbname as the default database for subsequent statements
mysql> source <file-path>
for example:
mysql> use phonebook;
mysql> source /tmp/phonebook.sql;
Important: make sure the sql file is in a directory that mysql can access to like /tmp
If you want to import a database from a SQL dump which might have "use" statements in it, I recommend to use the "-o" option as a safeguard to not accidentially import to a wrong database.
• --one-database, -o
Ignore statements except those those that occur while the default
database is the one named on the command line. This filtering is
limited, and based only on USE statements. This is useful for
skipping updates to other databases in the binary log.
Full command:
mysql -u <username> -p -o <databasename> < <filename.sql>
For Ubuntu/Linux users,
Extract the SQL file and paste it somewhere
e.g you pasted on desktop
open the terminal
go to your database and create a database name
Create database db_name;
Exit Mysql from your terminal
cd DESKTOP
mysql -u root -p db_name < /cd/to/mysql.sql
Enter the password:....
Before running the commands on the terminal you have to make sure that you have MySQL installed on your terminal.
You can use the following command to install it:
sudo apt-get update
sudo apt-get install mysql-server
Refrence here.
After that you can use the following commands to import a database:
mysql -u <username> -p <databasename> < <filename.sql>
The simplest way to import a database in your MYSQL from the terminal is done by the below-mentioned process -
mysql -u root -p root database_name < path to your .sql file
What I'm doing above is:
Entering to mysql with my username and password (here it is root & root)
After entering the password I'm giving the name of database where I want to import my .sql file. Please make sure the database already exists in your MYSQL
The database name is followed by < and then path to your .sql file. For example, if my file is stored in Desktop, the path will be /home/Desktop/db.sql
That's it. Once you've done all this, press enter and wait for your .sql file to get uploaded to the respective database
There has to be no space between -p and password
mysql -u [dbusername] -p[dbpassword] [databasename] < /home/serverusername/public_html/restore_db/database_file.sql
I always use it, it works perfectly. Thanks to ask this question. Have a great day. Njoy :)
