    Hi,
    How is it after you have rollback or restored the deleted data, that no. of rows still come back as 0?

    I have the exact same code as you at the 6 minute mark for the first example but when I run my code it's printing out the print statement for the except part. The operational error. Not sure why

    Will this work on the community edition? Because when I copy and pasted your code in, I got
    Database Created
    Table couldn't be Created
    Employee Entered
    ID : 1
    FName : Derek
    LName : Banas
    etc.

    Hi Derek, can you tell me where is the best place to put the code that creates (instantiates?) tables? In the constructor of my custom class, for example? I dont want the tables to be created every time i run my code, that doesnt make sense 🙂

    Edit:
    Nevermind, I have tackled the problem placing the code in the constructor of my DBTools class and changed the query to 'CREATE TABLE IF NOT EXISTS' Thanks for all the tutorials!

    what do you mean by nameTuple[1] in "rowNames = nameTuple[1] for nameTuple in theCursor.fetchall"

    Is this the correct full form and definition for blob :
    A Binary Large OBject (BLOB) is a collection of binary data stored as a single entity in a database management system. Blobs are typically images, audio or other multimedia objects, though sometimes binary executable code is stored as a blob. Database support for blobs is not universal.

    Hey, I'm getting an error when running the program even when I just copied and pasted the transcript saying:
    db_conn.execute("INSERT INTO Employees (FName, LName, Age, Address, Salary, HireDate)"
    sqlite3.OperationalError: table Employees has no column named Address
    Could someone help?

    At this point, are you making these videos with a sort of curriculum in mind, or are you just jumping around in topics?

    Hey Derek, after saving our database to .sql file,

    I hope you get what I'm asking.

    Hi Derek

    Are planning on creating a video of how to do Image Processing with Python?

  18. Cuong Bang Avatar

    It seems that there's a glitch at 17:16, the Total Rows should be 1 as you already rollback the delete :).

    Great content. Can't wait for one on GUI!
    Also, any Dream Theater fans here? You sound so much like Jordan Rudess, their keyboardist! Just a few tutorials more and I bet I'll start thinking it's the other way around. 🙂

    Your tutorials are awesome!

    I would like to know if you could make a tutorial that is specifically directed towards finance. For example coding trading programs and other finance and investment related things. If you cannot do this could you please refer me to someone or to some other tutorial where I can find these things?
    Thanks!
