not able to get SQLite database in python

Question

1) I am new to python and I am using SQLITE database. While setting up the connection I am not able to get the database(Which I already made in SQLite and tables as well)

2) While executing the insert query I am getting the following error : "sqlite3.OperationalError: no such table: MemberDetails"

HERE IS THE CODE:

import sqlite3
my_cursor = ""
conn = ""


# setting the connection with database
# def con_database_connection():
# try:
globals()
conn = sqlite3.connect('CareForNation.db')
# new_con = sqlite3.connect('CareForNation.db')
print("connection established successfully")
my_cursor = conn.cursor()
# except sqlite3 as error
# print("Connection failed")


# Login Admin Control
user_name = input("Enter user name")
user_password = input("Enter Password")
if user_name == "123" and user_password == "123":
    print("Login successful")
else:
    print("Invalid user name or password")


# Inserting member information
# con_database_connection()
mid = input("Enter Member ID")
member_name = input("Enter member name")
member_phone_number = input("enter phone number")
member_address = input("Enter address")

insert_data = my_cursor.execute("insert into MemberDetails(Member_ID, Member_Name, Phone_Number, address) "
                                "values('mid', 'member_name', 'member_phone_number', member_address)")

# abc = conn.executescript("select * from MemberDetails")

print("New data entered to Member details module")
conn.close()

Are you sure that there is a table "MemberDetails" in your database ? — Jona

The error seems pretty clear. What steps have you taken te verify that the database does indeed contain the specified table? Have you tried accessing the DBwith something like: sqlitebrowser.org? — Exelian

Also note that the sqlite3 module for python does NOT auto-commit. You'll have to commit your changes each time you close the file — Exelian

First create the table:

my_cursor.execute("""CREATE TABLE MemberDetails(
            mid text,
            member_name text,
            member_phone_number text,
            member_address text
            )""")

Then, replace

insert_data = my_cursor.execute("insert into MemberDetails(Member_ID, Member_Name, Phone_Number, address)"
                                "values('mid', 'member_name', 'member_phone_number', member_address)"
                                )

With:

with conn:
    my_cursor.execute("INSERT INTO MemberDetails VALUES (:mid, :member_name, :member_phone_number, :member_address)",
                      {'mid': mid, 'member_name': member_name, 'member_phone_number': member_phone_number, 'member_address': member_address})

Ah, you need to create the table first. Give me a minute and I will update the answer ..

[Updated]

I've made some change in your code it works perfectly now!

import sqlite3
my_cursor = ""
conn = ""


# setting the connection with database
# def con_database_connection():
# try:
globals()
conn = sqlite3.connect('CareForNation.db')
# new_con = sqlite3.connect('CareForNation.db')
print("connection established successfully")
my_cursor = conn.cursor()
# except sqlite3 as error
# print("Connection failed")


# Login Admin Control
user_name = input("Enter user name")
user_password = input("Enter Password")
if user_name == "123" and user_password == "123":
    print("Login successful")
else:
    print("Invalid user name or password")


# Inserting member information
# con_database_connection()
mid = input("Enter Member ID")
member_name = input("Enter member name")
member_phone_number = input("enter phone number")
member_address = input("Enter address")

my_cursor.execute("create table if not exists MemberDetails(Member_ID, Member_Name, Phone_Number, address)")
insert_data = my_cursor.execute("insert into MemberDetails (Member_ID, Member_Name, Phone_Number, address) values (?, ?, ?, ?)", (mid, member_name, member_phone_number, member_address))
# abc = conn.executescript("select * from MemberDetails")

print("New data entered to Member details module")
conn.close()
