In this article, we will discuss how we can count the number of rows of a given SQLite Table using Python. We will be using the cursor_obj.fetchall() method to do the same. This method fetches all the rows of a query result. It returns all the rows as a list of tuples. An empty list is returned if there is no record to fetch.

To create the database, we will execute the following code:

Python3




import sqlite3
  
# Connecting to sqlite
# connection object
connection_obj = sqlite3.connect('geek.db')
  
# cursor object
cursor_obj = connection_obj.cursor()
  
# Drop the GEEK table if already exists.
cursor_obj.execute("DROP TABLE IF EXISTS GEEK")
  
# Creating table
table = """ CREATE TABLE GEEK (
            Email VARCHAR(255) NOT NULL,
            Name CHAR(25) NOT NULL,
            Score INT
        ); """
  
cursor_obj.execute(table)
  
# inserting data into geek table
connection_obj.execute(
    """INSERT INTO GEEK (Email,Name,Score) VALUES ("geekk1@gmail.com","Geek1",25)""")
connection_obj.execute(
    """INSERT INTO GEEK (Email,Name,Score) VALUES ("geekk2@gmail.com","Geek2",15)""")
connection_obj.execute(
    """INSERT INTO GEEK (Email,Name,Score) VALUES ("geekk3@gmail.com","Geek3",36)""")
connection_obj.execute(
    """INSERT INTO GEEK (Email,Name,Score) VALUES ("geekk4@gmail.com","Geek4",27)""")
connection_obj.execute(
    """INSERT INTO GEEK (Email,Name,Score) VALUES ("geekk5@gmail.com","Geek5",40)""")
connection_obj.execute(
    """INSERT INTO GEEK (Email,Name,Score) VALUES ("geekk6@gmail.com","Geek6",14)""")
connection_obj.execute(
    """INSERT INTO GEEK (Email,Name,Score) VALUES ("geekk7@gmail.com","Geek7",10)""")
  
connection_obj.commit()
  
# Close the connection
connection_obj.close()

Output:

So by finding the length of this list which is return by fetchall(), we get the count of the total number of rows.

Python3




import sqlite3
  
# Connecting to sqlite
# connection object
connection_obj = sqlite3.connect('geek.db')
  
# cursor object
cursor_obj = connection_obj.cursor()
  
print("Count of Rows")
cursor_obj.execute("SELECT * FROM GEEK")
print(len(cursor_obj.fetchall()))
  
connection_obj.commit()
  
# Close the connection
connection_obj.close()

Output:
