Python: Create a table and insert some records in that table
Python SQLite Database: Exercise-5 with Solution
Write a Python program to create a table and insert some records in that table. Finally selects all rows from the table and display the records.
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()
# Create the table
cursorObj.execute("CREATE TABLE salesman(salesman_id n(5), name char(30), city char(35), commission decimal(7,2));")
# Insert records
cursorObj.executescript("""
INSERT INTO salesman VALUES(5001,'James Hoog', 'New York', 0.15);
INSERT INTO salesman VALUES(5002,'Nail Knite', 'Paris', 0.25);
INSERT INTO salesman VALUES(5003,'Pit Alex', 'London', 0.15);
INSERT INTO salesman VALUES(5004,'Mc Lyon', 'Paris', 0.35);
INSERT INTO salesman VALUES(5005,'Paul Adam', 'Rome', 0.45);
""")
conn.commit()
cursorObj.execute("SELECT * FROM salesman")
rows = cursorObj.fetchall()
print("Agent details:")
for row in rows:
print(row)
sqllite_conn = sql_connection()
sql_table(sqllite_conn)
if (sqllite_conn):
sqllite_conn.close()
print("\nThe SQLite connection is closed.")
Sample Output:
Agent details: (5001, 'James Hoog', 'New York', 0.15) (5002, 'Nail Knite', 'Paris', 0.25) (5003, 'Pit Alex', 'London', 0.15) (5004, 'Mc Lyon', 'Paris', 0.35) (5005, 'Paul Adam', 'Rome', 0.45) The SQLite connection is closed.
Alternate solution:
Python Code :
import sqlite3
conn = sqlite3 . connect ( 'mydatabase.db' )
cursor = conn . cursor ()
#create the salesman table
cursor.execute("CREATE TABLE salesman(salesman_id n(5), name char(30), city char(35), commission decimal(7,2));")
# inserting data into the table
cursor . execute ( """
INSERT INTO salesman(salesman_id,'name', 'city',commission)
VALUES(5001,'James Hoog', 'New York', 0.15)
""")
cursor . execute ( """
INSERT INTO salesman(salesman_id,'name', 'city',commission)
VALUES(5002,'Nail Knite', 'Paris', 0.25)
""")
cursor . execute ( """
INSERT INTO salesman(salesman_id,'name', 'city',commission)
VALUES(5003,'Pit Alex', 'London', 0.15)
""")
cursor . execute ( """
INSERT INTO salesman(salesman_id,'name', 'city',commission)
VALUES(5004,'Mc Lyon', 'Paris', 0.35)
""")
conn.commit ()
print ( 'Data entered successfully.' )
conn . close ()
if (conn):
conn.close()
print("\nThe SQLite connection is closed.")
Sample Output:
Data entered successfully. The SQLite connection is closed.
