Updating A Record

Updating A Record

You can even update a record (tuple) in a table through python script. The following example change the name “Priya” to “Priyanka” in a record in “student table”

Example

#code for update operation

import sqlite3

#database name to be passed as parameter

conn = sqlite3.connect("Academy.db")

#update the student record

conn.execute("UPDATE Student SET sname ='Priyanka' where Rollno='6'")

conn.commit()

print ("Total number of rows updated :", conn.total_changes)

cursor = conn.execute("SELECT * FROM Student")

for row in cursor:

print (row)

conn.close()

OUTPUT

Total number of rows updated : 1

(1, 'Akshay', 'B', 'M', 87.8, '2001-12-12')

(2, 'Aravind', 'A', 'M', 92.5, '2000-08-17')

(3, 'BASKAR', 'C', 'M', 75.2, '1998-05-17')

(4, 'SAJINI', 'A', 'F', 95.6, '2002-11-01')

(5, 'VARUN', 'B', 'M', 80.6, '2001-03-14')

(6, 'Priyanka', 'A', 'F', 98.6, '2002-01-01')

(7, 'TARUN', 'D', 'M', 62.3, '1999-02-01')
