SQLite NOT NULL
i am learning C# and using SQLite database. While setting up a table in SQLite browser, I have checked the NotNull box for a textfield. I have created a simply C# UI program, entered 3 name and purposedly leave 2nd name as empty textbox. When i goes back to check on the database table, it shows all three lines with the 2nd line is empty. I was wondering, why there is not exception or error prompted that Null is not accepted since i have checked the NotNull box for the textfield. It seems the table capture a data even it is empty. Anyone can enlightened me? Thanks.
Blank is not null.
