Python SQLite - Create Table

Neha Kumawat

a year ago

Using the SQLite CREATE TABLE statement you can create a table in a database.

Syntax

Following is the syntax to create a table in SQLite database −

CREATE TABLE database_name.table_name(
   column1 datatype PRIMARY KEY(one or more columns),
   column2 datatype,
   column3 datatype,
   .....
   columnN datatype
);

Example

Following SQLite query/statement creates a table with name CRICKETERS in SQLite database −

sqlite> CREATE TABLE CRICKETERS (
   First_Name VARCHAR(255),
   Last_Name VARCHAR(255),
   Age int,
   Place_Of_Birth VARCHAR(255),
   Country VARCHAR(255)
);
sqlite>
Let us create one more table OdiStats describing the One-day cricket statistics of each player in CRICKETERS table.

sqlite> CREATE TABLE ODIStats (
   First_Name VARCHAR(255),
   Matches INT,
   Runs INT,
   AVG FLOAT,
   Centuries INT,
   HalfCenturies INT 
);
sqlite>
You can get the list of tables in a database in SQLite database using the .tables command. After creating a table, if you can verify the list of tables you can observe the newly created table in it as −

sqlite> . tables
CRICKETERS ODIStats
sqlite>

Creating a Table Using Python

The Cursor object contains all the methods to execute quires and fetch data etc. The cursor method of the connection class returns a cursor object.
Therefore, to create a table in SQLite database using python
  • Establish connection with a database using the connect() method.
Establish connection with a database using the connect() method.
  • Create a cursor object by invoking the cursor() method on the above created connection object.
Create a cursor object by invoking the cursor() method on the above created connection object.
  • Now execute the CREATE TABLE statement using the execute() method of the Cursor class.
Now execute the CREATE TABLE statement using the execute() method of the Cursor class.

Example

Following Python program creates a table named Employee in SQLite3 −

import sqlite3
#Connecting to sqlite
conn = sqlite3.connect('example.db')

#Creating a cursor object using the cursor() method
cursor = conn.cursor()

#Doping EMPLOYEE table if already exists.
cursor.execute("DROP TABLE IF EXISTS EMPLOYEE")
#Creating table as per requirement
sql ='''CREATE TABLE EMPLOYEE(
   FIRST_NAME CHAR(20) NOT NULL,
   LAST_NAME CHAR(20),
   AGE INT,
   SEX CHAR(1),
   INCOME FLOAT
)'''
cursor.execute(sql)
print("Table created successfully........")

#Commit your changes in the database
conn.commit()

#Closing the connection
conn.close()

Output


Table created successfully........
