How can the presence of records in an SQL database table be determined?

To determine the presence of records in a SQL database table using Python, you can execute a query that checks the number of rows or the existence of at least one record.

Example using the sqlite3 library:

import sqlite3

conn = sqlite3.connect('example.db')
cursor = conn.cursor()

cursor.execute('SELECT EXISTS(SELECT 1 FROM table_name LIMIT 1)')
exists = cursor.fetchone()[0]

if exists:
    print('Records exist in the table')
else:
    print('The table is empty')

conn.close()

Here, the query SELECT EXISTS(SELECT 1 FROM table_name LIMIT 1) returns 1 if there is at least one record in the table, and 0 if not.
