Deletion Operation

Deletion Operation

Similar to Sql command to delete a record, Python also allows to delete a record. The following example delete the content of Rollno 2 from "student table"

Example

#code for delete operation

import sqlite3

#database name to be passed as parameter

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

#delete student record from database

conn.execute("DELETE from Student where Rollno='2'")

conn.commit()

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

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

for row in cursor: print(row)

conn.close()

OUTPUT

Total number of rows deleted : 1
