Enter data into a SQL table in python?

Question

I'm making a program that connects to a SQL database for me to enter in data. Instead of entering data into the table manually, I wanted to make a program do it. So it's asks me a series of questions, then inputs the answers into the table. I am not sure how to do that. My issue is at the end with the cursor execute.

I am not sure how I can incorporate the input answers into that execute function. Would it be something like this? The .format is showing up as a string, so I am not sure how to implement this.

VALUES
('{}'.format(category), '{}'.format(description), '{}'.format(date), '{}'.format(price), '{}'.format(vehicle))

Here is the code below:

import time
import pyodbc
conn = pyodbc.connect('Driver={SQL Server};'
                  'Server=TJDESKTOPPC;'
                  'Database=carparts;'
                  'Trusted_Connection=yes;')

cursor = conn.cursor()
cursor.execute('''
              SELECT * FROM carparts.dbo.modifications
           
               ''')
conn.commit()

# Menu starts below

database = "carparts"
print("Welcome to the program!")
print()
print("You are connected to {} database".format(database))
print()
print()
print("The current columns in the table are...")
print()
conn = pyodbc.connect('Driver={SQL Server};'
                  'Server=TJDESKTOPPC;'
                  'Database=carparts;'
                  'Trusted_Connection=yes;')

cursor = conn.cursor()
cursor.execute('SELECT * FROM carparts.dbo.modifications where 1=2')
headers = [i[0] for i in cursor.description]
print(headers)
print()
print("Categories are: engine, suspension, exhaust, or transmission")
print()
category = str(input("Please enter category: "))
print()
description = str(input("Please enter the description of the part: "))
print()
purchase_date = input("Please enter the purchase date in (YYYY-MM-DD): ")
print()
price = int(input("Please enter the price amount: "))
print()
vehicle = str(input("What vehicle is this for? (Model): "))
print()
print("Thanks!")
time.sleep(3)
print("\n" * 5)  # This will the clear screen of any previous code
print("Adding the category, description, purchase date, price, and vehicle to the table...")
time.sleep(2)

cursor.execute('''
            INSERT INTO carparts.dbo.modifications (category, description, purchase_date, price, 
vehicle)
            VALUES
            ('exhaust', 'Flowmaster Cat-back Exhaust', '2015-12-08', '551', 'focus_st')
           ''')
conn.commit()

The snippet above for INSERT INTO actually works, but I need to put the values in manually how it is. So how do I get the variable input (category, description, date, etc) in that string?

Try this,

Here you need to provide your variable data you want to insert and also need to add {} in single quotes like this '{}'. So that your after providing value in format "'{}'".format("category_input") is looks like 'category_input' and it doesn't effect if you have a number.

cursor.execute('''INSERT INTO carparts.dbo.modifications (category, description, 
    purchase_date, price, vehicle) VALUES ('{}', '{}', '{}', '{}', '{}')'''.format(category, description, purchase_date, price, vehicle))

Thank you SO MUCH! I had just missed the spot where the .format needed to go! Thank you so much Vishal, this is working flawlessly now! – TJ Struck Dec 09 '20 at 20:22
