Cursors in sqlite3 python are objects that act as a pointer to the results of a query. They enable you to fetch, add, modify or delete data from a database. The cursor can also be used to traverse through the rows of a query result.
At 37:21 he mispronounces tuple as "toople" and then corrects himself after immediately remembering the correct pronunciation. As a non-native speaker of English from India, this brings a smile to my face. Because this is exactly what we do at times. When we learn English from textbooks, we have our pronunciation for some words, and then after watching native speakers pronounce it differently we try to remember the correct pronunciation. But still end up pronuncing it the way we first learned it in spite of knowing the correct way. The word that immediately comes to my mind that I personally mispronounce is "environment".
Thanks John, this was really helpful. Just want to note something I got hung up on; if you delete the last row in a table, that rowid will be REUSED when you add a new item to the table UNLESS you use the AUTOINCREMENT keyword. In other words, if the last rowid is 6, and you delete it (and all of that person's data)... then the last rowid is 5. But, if you add a new item, the new person's data will be added to a row that ALSO has the rowid of 6. This can cause issues when referencing data by rowid later on.
Wow, just wow. This is one superb course for beginners like myself. I followed the whole instructions and created an employees db. I reached a little far trying to incorporate nulls and blobs which caused me probs at the end. Ha. Had to drop back to the text and email demos but everything worked the first time after I corrected my typos. Ha. Thank you for a marvelous tutorial!
this is very easy to understand, good job, very few sqlite3 tutorials actually show the syntax of the sql knowledge and doesn't assume we learned the sql language beforehand, and this is one of them. Fantastic!

This is an older video but i found it very helpful so thank you first off! Secondly, if any of you are using VS Code instead of sublime you will need to make sure you are physically inside of the folder through the explorer tab. Once inside select the sqlite folder then go to git bash and follow his steps from there!
What kind of witch sorcery is this channel? As soon as I need to learn something for a project, a new course is released on the topic. This is insane and might be the tenth time it's happening. Keep up the good work!!!
Made sense to me, but that was because I already knew SQL and the SQLite command line. Might be easier to demonstrate SQLite command line and then ask what if we want to do this as part of a larger Python program? At the SQLite command line one can immediately demonstrate the newly created table with: SELECT customers *; If a student asks, why not do everything in SQL? Ask the student, "What if you want to graph the data?" SQL doesn't have matplotlib or even the tools to produce a formatted report. So, Python and SQL (SQLite) make a good team.
Hello John, I worked on a program that asks the number of records to be inserted: import sqlite3 conn = sqlite3.connect('student.db') #create a cursor c = conn.cursor() vnaam = ' ' #Inserting records aant = int(input('Number of records to be inserted')) for x in range(aant): vnaam = input("First name? :") anaam = input("Surname? :") rek = input("Arithmetic score :") taal = int(input("Language score :")) studenten = [ (vnaam, anaam, rek, taal) ] c.executemany("INSERT INTO studenten VALUES (?,?,?,?)", studenten) print("Inserted") #Commando uitvoeren conn.commit() #afsluiten! conn.close() And it works :) (Thanks to your clear way of instructing us :)
Hint: the print function accepts multiple arguments where each one is separated by a space when printed. I.e. print( item[0], item[1]) will print Jon Elders to the screen.
c.execute("INSERT INTO Customers VALUES (?,?,?)", (List)) sqlite3.ProgrammingError: Incorrect number of bindings supplied. The current statement uses 3, and there are 2 supplied. I've rewound the video like dozens of times now and watched it. Finally I noticed that I'm using execute() instead of executemany(). c.executemany("INSERT INTO Customers VALUES (?,?,?)", List) now it works.
I dont know if you would answer any questions here on this specific video, most likely not, but ill ask anyway. I was wondering if SQLite would be ok to use in production as the default database for a small project? Im building a small web app in Django as a reference/ educational site and have a database of at most 50 records. I dont have the option for users or allowing user data so the database wont grow, it will stay at 50 rows. Is this ok for SQLite as my main database for my django project or should it only be used for development and instead use MySQL/ PostgreSQL?
Thank you for this super helpful video! Keep up the awesome work. I've been really enjoying your courses on RUclips. You're such an awesome instructor!
In the delete section: Don''t convert the id to string in the app.py file instead convert it into an iterable by c.execute("DELETE FROM customers WHERE rowid = (?)", [id]) or c.execute("DELETE FROM customers WHERE rowid = (?)", (id,)) Thanks for the good video.
As far as I know, docstrings aren't the same as triple quote strings. Docstrings are indeed expressed on tripple quote strings, but it means something more specific, which is the on code documentation for classes and functions, actually working as source code comments, but the syntax accepts this particular case because it's industry standard. Edit: also, as far as I know, SQL is case INSENSITIVE, actually, but it's good practice to capitalize reserved words to distinguish it from context defined elements (names, parameters, etc).
Surprised that value passed to query has to be a tuple. This does not work: cursor.execute("SELECT * FROM customers WHERE firstname=?", customer_first_name)
This Course is really easy to follow and super useful for people who want to start using SQLite, but I wanted to understand 'JOIN' concept which is not explained neither mentioned here, so i guess I will look for some more content.
1:21:03 it worked with '6' as 🐍 doesnt treat 6 as a sequence (and we need to pass a sequence for: .execute(..., here). '6' is iterable and it handled the issue
Hi! just a remark: contrary to what you say in the first part, SublimeText is free for evaluation but if you do read the little popup window (or the website) you have to buy a license for continuous usage, it's not a donation, it's a license.

It would be good to show readonly vs read+write connections to the sqlite3 database file, which comes in handy if you're creating a flask web app which will be used by multiple individuals at once.
Hello John, I followed closely your instructions in using tkinter and making a database. I changed your example a bit, in that I only ask for a first name and underneath that a number of entry boxes in which scores on some test can be filled in. Two questions: 1. How to get the results in some listbox or something like that 2. How can I send the results to a printer. This printer thing a a huge challenge for me :) Thank you for your fantastic video's !!
you can execute this query SELECT * FROM [table name] and then you can just use this method fetchall() on the cursor while assigning it to a variable and now your variable simply contains a list of tuples and each tuple contains values of each row corresponding to the column names.
at 1:26:15 took me half a day to understand that little "quirk" of comma in "(email,)" and found out that it is also possible to write "[email]" as both cases returns an iterable.
I'm really scratching my head 9n passing rowid as a string, and then it "just works". Stuff like this drives me crazy. I guess it's no worse than perl and the way it used the context of what it was seeing in the code instead of following a strict syntax grammar. perl can produce incredible results, but things written in it are pretty much unmaintainable. A write-only language. ;)
@@tonyfremont I am not sure if your comment should be under mine. but It seems what you mentioned is about parameter type of sqlite's execute function.

Thanks a lot John. In this lecture i m just stucked at 1:10:15. When i tried to import database. I got an error ModuleNotFoundError: No module named 'database'.
1:20:00 Isn't it because you forgot to wrap the id argument in a tuple? c.execute("DELETE from customers WHERE rowid = (?)", (id,)) could be wrong though
after i dropped my table, nothing is working, I tried to create a new table from the first lesson, but it says database doesn't exist (even though its in my folder?
does sublime text automatically highlight sqlite3 syntax inside of python strings? I'm using vscode and it doesn't do that. I've found (haven't yet installed) an extension that supposed to do it if you type --sql or something at the beginning of the string
my sublime text3.2.2 seems not highlighting sqlite3 syntax, but in his video it does. I googled but can not figure out how to do so, did you had a better luck?
If you're having trouble with this part of deleting a query with a rowid over 9 then look below c.execute("DELETE from customers WHERE rowid = (?)", id) It's because when you call the function database.delete_one('10') You will get the error " Incorrect number of bindings supplied.

If you're having trouble with this part of deleting a query with a rowid over 9 then look below
c.execute("DELETE from customers WHERE rowid = (?)", id)
It's because when you call the function
database.delete_one('10')
You will get the error " Incorrect number of bindings supplied. The current statement uses 1, and there are 2 supplied."
to fix this, change
rowid = (?)", id)
to
rowid = (?)", [id])
allowing
database.delete_one('10') to work with double digits and more
You no longer need to pass the function argument as a string - database.delete_one(10) will now work WITH or WITHOUT converting the numbers to string
