8. Row Count in SQLite Table

Write a Python program to count the number of rows of a given SQLite table.

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));")
    print("Number of records before inserting rows:")
    cursor = cursorObj.execute('select * from salesman;')
    print(len(cursor.fetchall()))
# 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()
    print("\nNumber of records after inserting rows:")
    cursor = cursorObj.execute('select * from salesman;')
    print(len(cursor.fetchall()))
    
sqllite_conn = sql_connection()
sql_table(sqllite_conn)

if (sqllite_conn):
  sqllite_conn.close()
  print("\nThe SQLite connection is closed.")

Sample Output:

Number of records before inserting rows:
0

Number of records after inserting rows:
5

The SQLite connection is closed.

• Write a Python program to connect to a SQLite database, count the number of rows in a specified table using a SELECT COUNT(*) query, and print the result.
• Write a Python function that accepts a table name and returns the row count from that table, printing the count in a formatted message.
• Write a Python script to update a table and then count and print the number of rows before and after the update operation.
• Write a Python program to dynamically count the rows of multiple tables in a SQLite database and then print a summary report.
