SQLite Databases With Python - Full Course

In this course you’ll learn the basics of using SQLite3 with Python. SQLite is an easy-to-use database engine included with Python.
You’ll learn how to create databases and tables, add data, sort data, create reports, pull specific data, and more. For this course you should already have a basic knowledge of Python programming, but you don’t need to know anything at all about databases or SQLite.

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.

[@jimcallahan448]

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.

[@vhoover3609]

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.

[@myriamt6340]

WALTER WHITE teaching me SQLITE, what a time to be alive :D

[@WillNicholson]

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.

Hi John, I watched all clips. Thx for your full course "Sqlite databases with Python". Well done!!!

[@dexternepo]

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".

[@MrMoKhalaf]

[@JuanThomasAlvarez]

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.

[@Lucaischz]

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).

[@sanjayraj1700]

Thank you John. It was really helpful :)

[@Lennardish]

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 !!

[@BabaBoota-lg2pq]

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.

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.

In the Delete Records video, I had created 7 records and deleted rowid = 4. My updated table had the following rowid's: 1, 2, 3, 5, 6, 7. I was assuming the rowid's would have stayed the same and the records would have simply shifted up. Is there any way to get that rowid 4 back or is gone forever?

Could I insert data in an specific rowid? or just at the end? Thank you, thank you for the feedback
