GROUP BY clause in MySQL is used to group rows that have the same values in specified columns into summary rows, often used with aggregate functions like COUNT(), SUM(), AVG(), MIN(), and MAX() to perform calculations on each group. Essentially, it allows you to aggregate data across multiple rows and summarize it into a smaller set of results. AUTOINCREMENT keyword in SQLite is used to automatically generate a unique integer value for a column, typically for a primary key. It is used in combination with the INTEGER PRIMARY KEY column type to automatically increment the value of the column each time a new row is inserted into the table. The purpose of AUTOINCREMENT is to ensure that each row has a unique identifier, which is particularly useful for the primary key field.
