01:23 Working on Colab platform and Importing sqlite3 to create database.
03:19 Step-by-step guide on writing multiline SQL queries to create a table in SQLite.
06:11 Explanation of using Python's try-except-else block for executing the table creation query safely.
07:58 Executing DROP table query to delete the table in SQLite database
09:00 Adding sample data row to the table by executing query
13:05 Listing all the rows of data available in the table
14:09 Adding data to table to check the column constraints
16:57 Adding string data to integer column in SQLite table

In this video, we introduce the basic constraints used in SQLite databases, focusing on column-level data types. This is the first part of our series on SQLite constraints, where we explain how to define primary keys, unique constraints, and NOT NULL constraints without using the CHECK() function. Stay tuned for the next part where we'll dive deeper into more complex constraints!
