From psql type \list or \l to list all the databases. To get the list of databases, enter into the interactive terminal of PostgreSQL, by typing psql from command line.Then type Heroku Postgres into the Add-ons search field. Calling execute()function with CREATE DATABASE creates a database on the PostgreSQL server. To attach a PostgreSQL database to the app you just created, you need to navigate to the Resources tab in the header of your newly created apps dahsboard.Pass the Python string containing the SQL statement while calling the execute() method of the database cursor.Define a Python string, which contains the SQL command CREATE DATABASE.Through the connection object obtain a cursor object by calling the cursor() method on the connection object.Create a connection object to the PostgreSQL server by providing the logon credentials and calling the function nnect(). ![]() To install Psycopg2 use the command: pip install psycopg2.If the import fails use the pip command to install Psycopg2. Import the Psycopg2 module inside a Python program. Create a database statement In the above syntax, the name shows the database name we have used to create a new database in PostgreSQL.Using Psycopg2 a Python program can create a database on PostgreSQL server.Ĭreating a PostgreSQL database using Python and Psycopg2: Psycopg2 is the Python client library for PostgreSQL.The user should have sufficient privilege to create a database on PostgreSQL server. Remember, only a valid user of the PostgreSQL server does creation of any SQL object on a PostgreSQL server.CREATE DATABASE is one of the DDL statements supported by the PostgreSQL Database Management System.A database acts as a container for a variety of SQL objects like tables, stored procedures and functions, indexes and views.Subsequently, the table is inserted with several rows and PostgreSQL is queried by an application program using a language like Python. A simple task often done by any database developer is to create a database and create a table underneath the database.
