How to Bulk Upload Postgres Line Breaks

In this Postgresql tutorial, nosotros will learn about "Postgresql import SQL file" using different methods and platforms, nosotros will create and insert some data into the Postgresql database using the SQL file or by importing the SQL file.

Nosotros are going to comprehend the following topics:

Postgresql import SQL file command line
Postgresql import SQL file pgadmin iv
Postgresql import SQL file docker
Postgresql import SQL file windows
psql import SQL file permission denied
Heroku Postgres import SQL file

When nosotros want to create a database or we want to create tables in an existing database using SQL files.

To create a database, we may take a created an SQL file that contains the command to restore the database, for that nosotros will apply the already created SQL file.

Postgresql import SQL file command line

In Postgresql, we use the psql command to import SQL files or databases.

And so "What is psql?." Psql is an interactive-last or terminal-based front-end that enables u.s. to type in queries and send those queries to the Postgresql database interactively.

Psql provides the number of flags or options that nosotros can employ with the psql command to connect with different databases, users, and hosts of the Postgresql server.

Some of the near common flags or options are:

-U username: username of the database that you want to connect.
-d dbname: name of the database to connect to.
-h hostname: proper noun of the host car on which the Postgresql server running.

Permit's connect to the PostgreSQL database and import the SQL file using the command line.

Open the command line or cmd on your auto and follow the below instructions.

Earlier importing an SQL file, yous must have an empty database so create database name postdata using the beneath command.

          CREATE DATABASE postdata;

Check the list of all databases using \50 and type \q to get out from the Postgresql command-line tool.

At present we take created a database "postdata", permit's import an SQL file ( database.sql that contains a command to create table name "new" ) into the newly created database "postdata".

          psql -h localhost -U postgres -d postdata -f D:\Backup\database.sql

And login into your database using the below command.

          psql -U postgres -d postdata

Then list the table that you lot take created in the postdata database using \dt.

          postdata=# \dt

As nosotros can meet in the above output, we accept created a new tabular array by importing a pre-created SQL file into the Postgresql database.

Postgresql import SQL file pgadmin 4

To import the SQL file using pgAdming follow the below instructions.

Open up pgAdmin application and select the database.

Right-click on the selected database and click on Query Tool.

After clicking on Query Tool, The SQL Editor Console appears abreast the Browser section of the pgAdmin awarding.

Then click on small binder-icon in Query Toolbar of The SQL Editor Console to import or upload the SQL file.

Now Select the SQL file or navigate the folder where SQL file be and click on SELECT button at bottom right-corner.

Click on small play-icon in Query Toolbar or press F5 from your keyboard to execute the query that appears in Query Editor after importing the SQL file.

Well, we have successfully imported the SQL file using pgadmin, let' run across the created table using the below command.

          SELECT * FROM new; -- new is the name of table

Postgresql import SQL file docker

When we want to import an SQL file using docker, your system must have a docker installed, if non, go to the official documentation of the docker website then come back.

Starting time, create the Postgresql database using docker-compose, if you don't know and then follow the below instructions.

Create the docker-compose file in your root binder, this file is a configuration file to run the Postgresql in docker, the file is called docker-etch.yml.

Configure the Postgres docker-etch file, nosotros are going to the image for Postgresql available on the docker hub, there are 2 things that nosotros need to put in the configuration file.

Import the Postgres image in Docker etch
Configure the database according to your demand and utilise it on estimator.

Open the docker-compose.yml file and paste the below instructions:

          # A Docker Compose must always first with the version tag. # Nosotros use '3' because information technology's the last version. version: '3'  # You lot should know that Docker Compose works with services. # 1 service = 1 container. # For instance, a service, a server, a client, a database... # We utilise the keyword 'services' to start to create services.  services:    # The name of our service is "database"   # but you lot can employ the name of your choice.   # Note: This may change the commands you are going to apply a fiddling scrap.     database:     # Official Postgres image from DockerHub (we use the last version)      image: 'postgres:latest'     restart: always      # Past default, a Postgres database is running on the 5432 port.     ports:       - 5432:5432      environment:       POSTGRES_USER: postgres # The PostgreSQL user       POSTGRES_PASSWORD: 12345 # The PostgreSQL password        POSTGRES_DB: default_database # The PostgreSQL default database

At present, you can run the database and connect to it.

Allow's run the docker file using the below command in the last.

          docker-compose up

At this point, afterward running the above command it creates the container and image file in docker.

Time to import the SQL file, so create SQL file proper noun data.sql in your root directory with commands.

In your current terminal type nano data.sql to create the file and write the below command in that file.

          data.sql --file name where we volition write the below commands  CREATE Table new(id INT,name VARCHAR);  INSERT INTO new(id,name)values(1,"Travis");

SQL file created successfully, let's import the file using docker, use the below commands.

          docker container exec -i kumar_saurabh_database_1 psql -U postgres default_database < data.sql

Now open the Docker application from your desktop, that you accept installed while following official documentation for installing docker, select container from the awarding.

Later then click on the CLI ( Command line tool ) icon of the container and information technology will launch the command-line tool that lets yous talk to the Docker daemon.

In the docker container command-line tool, to verify the imported sql file that contains commands to create a new table in the database using the beneath commands.

          psql -U postgres -d default_database -- login into database    /dt -- to listing all the tables in current database    SELECT * FROM new; -- to prove all the data or records in the table

As we can see in the above output, we have successfully imported the SQL file using docker and created a new tabular array with some data in it.

Psql import SQL file permission denied

Sometimes when nosotros import the SQL file we get fault permission denied, beginning let's see the error while importing the SQL file.

For Windows users, Enter into psql command prompt by using the beneath control, if information technology asks for a password enter the password for the user of psql.

          psql -U postgres

Now, think that nosotros take an SQL file on our calculator somewhere like D:\Backup\proper name.sql and we want to import that file, for that use the beneath control.

          \i D:\Backup\proper name.sql

After running the in a higher place command, we get an mistake Permission denied.

To solve the error, utilise the double slashes ( \\ ) in the identify of unmarried slashes ( \ ) and wrap the path of the SQL file within a single quotation mark ( ' ' ), use the below command.

          \i 'D:\\Fill-in\\proper name.sql'

In the above output, nosotros have imported the SQL file successfully, created the table with some information in it, and solved the problem Permission denied.

For Linux users, Login into Postgressql equally a Postgres user to access the databases and then enter into psql prompt using the below command:

          sudo su -l postgres   -- later the above command enter the psql control  psql  -- and then enter the beneath control to import the SQL file  \i '//domicile//saurabh//database.sql

Use the double slashes ( // ) in the identify of single slashes ( / ) and wrap the path of the SQL file within a single quotation marker ( ' ' ), use the beneath command.

Now, we have also solved the error for Linux systems.

Heroku Postgres import SQL file

In Heroku, to import the SQL file start, we need to install Heroku CLI on our system, and after installing Heroku CLI, also install the Postgresql database from the official website of Heroku so come back hither.

Employ the below instructions :

Open your terminal and login into your Heroku account using the below command.

          heroku login

After login, Become to the Heroku website where yous have created the database while following the in a higher place official website and click on the name of your database.

So click on the Setting tab and click on View Credentials.

Note down or re-create the Heroku CLI command and paste information technology into your terminal or command-line to login into the database.

At present, Nosotros accept logged into the database, allow' import the SQL file.

Nosotros have successfully imported the SQL file using Heroku and also created a new tabular array.
