import sqlite3 as sql | |
import os | |
import csv | |
from sqlite3 import Error | |
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);''') | |
conn.execute('''INSERT INTO Employee(Name, Salary) VALUES('Soniya', 50000);''') | |
conn.execute('''INSERT INTO Employee(Name, Salary) VALUES('Priya', 60000);''') | |
conn.commit() | |
# To view table data in table format | |
print "******Employee Table Data*******" | |
cur = conn.cursor() | |
cur.execute('''SELECT * FROM Employee''') | |
rows = cur.fetchall() | |
for row in rows: | |
print(row) | |
# Export data into CSV file | |
print "Exporting data into CSV............" | |
cursor = conn.cursor() | |
cursor.execute("select * from Employee") | |
with open("employee_data.csv", "w") as csv_file: | |
csv_writer = csv.writer(csv_file, delimiter="\t") | |
csv_writer.writerow([i[0] for i in cursor.description]) | |
csv_writer.writerows(cursor) | |
dirpath = os.getcwd() + "/employee_data.csv" | |
print "Data exported Successfully into {}".format(dirpath) | |
except Error as e: | |
print(e) | |
# Close database connection | |
finally: | |
conn.close() |
Here I'm getting error on .format syntax
