Does SQLite auto generate ID?
As you can see clearly from the output, SQLite implicitly creates a column named rowid and automatically assigns an integer value whenever you insert a new row into the table. If your data reaches this maximum value and you attempt to insert a new row, SQLite will find an unused integer and uses it.
How do you auto increment an ID?

Tip: To specify that the “Personid” column should start at value 10 and increment by 5, change it to IDENTITY(10,5) .
Does SQLite have Autoincrement?

Does SQLite support enum?
