try:
# Connect to database
conn=sql.connect('mydb.db')
# Create Table into database
conn.execute('''CREATE TABLE IF NOT EXISTS Employee(Id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,\
Name TEXT NOT NULL, Salary INT NOT NULL
);''')
# Insert some values to database
conn.execute('''INSERT INTO Employee(Name, Salary) VALUES('Laxmi', 30000);''')
conn.execute('''INSERT INTO Employee(Name, Salary) VALUES('Prerna', 40000);''')
conn.execute('''INSERT INTO Employee(Name, Salary) VALUES('Shweta', 30000);''')

print "Data exported Successfully into {}".format(dirpath)
except Error as e:
print(e)
