In this article, we will discuss the DROP command in SQLite using Python. But first, let’s get a brief about the drop command.
DROP is used to delete the entire database or a table. It deleted both records in the table along with the table structure.
Syntax: DROP TABLE TABLE_NAME;
For dropping table, we will first create a database and a table in it. Let’s create a table in the database.
Python3
# importing sqlite module import sqlite3 # create connection to the database # Lazyroar_database connection = sqlite3.connect('Lazyroar_database.db') # create table named address of customers with # 4 columns id,name age and address connection.execute('''CREATE TABLE customer_address (ID INT PRIMARY KEY NOT NULL, NAME TEXT NOT NULL, AGE INT NOT NULL, ADDRESS CHAR(50)); ''') # close the connection connection.close() |
Output:
Now, Insert 5 records into the customer_address table.
Python3
# importing sqlite module import sqlite3 # create connection to the database # Lazyroar_database connection = sqlite3.connect('Lazyroar_database.db') # insert records into table connection.execute( "INSERT INTO customer_address VALUES (1, 'nikhil teja', 22, 'hyderabad' )") connection.execute( "INSERT INTO customer_address VALUES (2, 'karthik', 25, 'khammam')") connection.execute( "INSERT INTO customer_address VALUES (3, 'sravan', 22, 'ponnur' )") connection.execute( "INSERT INTO customer_address VALUES (4, 'deepika', 25, 'chebrolu' )") connection.execute( "INSERT INTO customer_address VALUES (5, 'jyothika', 22, 'noida')") # close the connection connection.close() |
Output:
After insertion let’s see how to execute the drop table command.
Python3
# importing sqlite module import sqlite3 # create connection to the # database geek connection = sqlite3.connect('Lazyroar_database.db') # drop table connection.execute("DROP TABLE customers_address") print("data dropped successfully") # close the connection connection.close() |
Output:
