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 :)
I am trying to run this command using python and it is running well with mongodb version under 3.4.x, but doesn't work with 3.4.x.
This is the command:
su - mongod -c "/usr/bin/mongo admin -u admin -p password
--authenticationDatabase admin --port 27017 --eval 'version()'
And this is the error that I got:
MongoDB shell version v3.4.14
connecting to: mongodb://127.0.0.1:27017/admin
MongoDB server version: 3.4.14
2018-04-26T17:34:06.036+0000 E QUERY [thread1] Error: Authentication failed. :DB.prototype._authOrThrow#src/mongo/shell/db.js:1461:20#(auth):6:1#(auth):1:2:
However when I ran the exact same command on the command line, I got the expected result:
MongoDB shell version v3.4.14
connecting to: mongodb://127.0.0.1:27017/admin
MongoDB server version: 3.4.14
3.4.14
How to solve this?
Platform: LINUX.
I am a beginner of MongoDB and pymongo. After installing pymongo, here is a simple test I tried on ipython:
import pymongo
client = pymongo.MongoClient();
# Also tried to specify the local host and port number
db = client['myDB']
collections = db['temptables']
collections.insert({'a':'1'})
At this point, it chokes. And in the end, spits out a "Error 111: connection refused" error. So, I tried invoking MongoDB straight from the terminal and I still got the error below [look at the far end]. So, I searched a bit and tried:
removing the lock ( sudo rm /var/lib/mongodb/mongod.lock ). Turns out there was no lock in the first place.
sudo mongod --repair
I even saw a suggestion to comment out the host and port number from the config file. Tried that too, didn't work.
None of the above worked.
This is the error I see when I try to invoke mongodb from command line.

Help, please.
Your mongo server isn't running.
You can confirm this by executing sudo ps -ef | grep mongod
If you have mongo installed and in your path, you can execute:
cd && mkdir -p ~/temp_mongo_db && mongod --dbpath=./temp_mongo_db
This will launch mongo and place all database files in your home directory under 'temp_mongo_db'.
Finally, in a new terminal window, execute sudo ps -ef | grep mongod again. You'll now see mongod running.
If you want to run mongo in production, you should configure it to be managed by SystemD or some other init system.
I'm trying to connect to ms sql server hosted on a windows pc from a linux box. I'm trying to follow these instructions: http://www.freetds.org/userguide/serverthere.htm
Now, I verified that I can ping and telnet into the PC running the server. And I reached the place where the instructions are to run this:
Example 8-3. Connecting to the server, bypassing freetds.conf
$ cd src/apps
$ TDSVER=7.0 ./tsql -H myhost -p 1433 -U user
I cannot for the life of me figure out where src/apps is.
and when I try to run
$ ./tsql -S myserver -U user
or
$ tsql -S server-ip -U myusername -P mypassword
I get tsql command not found. What is happening?
I just wanted to install a PostgreSQL Database. After 3 hours of trying I do not know what else to do. My last try included installing PostgreSQL via Homebrew -> Works perfectly fine.
But typing this:
which psql
I got this: /usr/local/bin/psql
From my view this sort of Path is wrong, a I saw a different one in most tutorials. But I have no idea what to do.
But I went on trying:
createuser -U postgres yrkIO -P
And the terminal asked me for a password only to give me this:
createuser: could not connect to database postgres: FATAL: role "postgres" does not exist
What can I do, I just want to run a PostgreSQL on my Python Flask App?
Have you tried it without forcing a password?
createuser -s -r postgres
This worked for me.
Also, remember to start a server
Start:
pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start
Stop server:
pg_ctl -D /usr/local/var/postgres stop -s -m fast
