This was done by specifying the name of the table as well as the columns into which we need to insert the data into.

Lastly, we should run the INSERT statement via the execute() method to add the data into the table.Ĭur.execute( "INSERT INTO STUDENT (ADMISSION,NAME,AGE,COURSE,DEPARTMENT) VALUES (3420, 'John', 18, 'Computer Science', 'ICT')") Īfter running this code we have inserted a single record into our database table. Next, we should create a cursor object by calling the cursor() method. Again, we must first establish a connection to the database server by calling the connect() function. We can insert either a single record or multiple records into a Postgres database table. The above output shows that the table was created successfully. The close() method will close the connection to the database.Īt this point we have created a table with 4 columns, all of which have various data types. The commit() method helps us apply the changes that we have made to the database, and these changes cannot be undone if commit() runs successfully. The following example demonstrates this: import psycopg2Ĭon = nnect(database= "postgres", user= "postgres", password= "Kaliakakya", host= "127.0.0.1", port= "5432")

"Committing" the connection tells the driver to send the commands to the database. Finally, we need to commit and close the connection. We then call the execute() method of the cursor object to help us in creating the table. This cursor object is used to actually execute your commands. We also create a cursor object by calling the cursor() method that belongs to the connection object. This query should be executed after establishing a connection to the database.
To create a Postgres table in Python, we use the CREATE TABLE SQL statement. The output in the above code shows that the connection to the database has been established successfully. Note that the values for the above parameters should be correct for the connection to be successful. If you don't provide this, the default one will be used, which is 5432. For example, a domain name, "localhost", or an IP address. host: The address of the database server.password: The database password for the user.user: The username to be used for authentication.database: The name of the database you need to connect to.The following is the list of parameters that have been passed to the connect() method:

The following example demonstrates how to establish a connection to the database named "postgres": import psycopg2Ĭon = nnect(database= "postgres", user= "postgres", password= "", host= "127.0.0.1", port= "5432")
Next, you should create a cursor object to help you in execution of your SQL statements. To connect to your database, you should first create a connection object representing the database. Once the module has been installed, you can use it to connect to your database in your application.
