Python: Create a SQLite table within the database

Python SQLite Database: Exercise-3 with Solution

Write a Python program to connect a database and create a SQLite table within the database.

Structure of agent_master table:

agent_code char(6),
agent_name char(40),
working_area char(35),
commission decimal(10,2),
phone_no char(15) NULL);

Sample Solution:

Python Code :

import sqlite3
from sqlite3 import Error
def sql_connection():
   try:
     conn = sqlite3.connect('mydatabase.db')
     return conn
   except Error:
     print(Error)
def sql_table(conn):
   cursorObj = conn.cursor()
   cursorObj.execute("CREATE TABLE agent_master(agent_code char(6),agent_name char(40),working_area char(35),commission decimal(10,2),phone_no char(15) NULL);")
   print("\nagent_master file has created.")
   conn.commit()
sqllite_conn = sql_connection()
sql_table(sqllite_conn)
if (sqllite_conn):
 sqllite_conn.close()
 print("\nThe SQLite connection is closed.")

Sample Output:

agent_master file has created.

The SQLite connection is closed.

Alternate solution:

Python Code :

import  sqlite3

# connect to the database.
conn  =  sqlite3 . connect ( 'mydatabase.db' )
# defining a cursor
cursor  =  conn . cursor ()

# creating the table (schema) agent_master
cursor . execute ( """
CREATE TABLE agent_master(agent_code char(6),
agent_name char(40),working_area char(35),
commission decimal(10,2),phone_no char(15) NULL);
""" )
print("\nagent_master file has created.") 
# disconnecting ...
conn . close ()
print("\nThe SQLite connection is closed.")

Sample Output:

agent_master file has created.

The SQLite connection is closed.

Python: Tips of the Day

Find current directory and file's directory:

To get the full path to the directory a Python file is contained in, write this in that file:

import os 
dir_path = os.path.dirname(os.path.realpath(__file__))

(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)

To get the current working directory use

import os
cwd = os.getcwd()

Documentation references for the modules, constants and functions used above:

  • The os and os.path modules.
  • The __file__ constant
  • os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
  • os.path.dirname(path) (returns "the directory name of pathname path")
  • os.getcwd() (returns "a string representing the current working directory")
  • os.chdir(path) ("change the current working directory to path")
