How does Autoincrement work in SQLite?

Question

SQLite AUTOINCREMENT is a keyword used for auto incrementing a value of a field in the table. We can auto increment a field value by using AUTOINCREMENT keyword when creating a table with specific column name to auto increment. The keyword AUTOINCREMENT can be used with INTEGER field only.

Does primary key auto increment SQLite?

On an INSERT, if the ROWID or INTEGER PRIMARY KEY column is not explicitly given a value, then it will be filled automatically with an unused integer, usually one more than the largest ROWID currently in use. This is true regardless of whether or not the AUTOINCREMENT keyword is used.

What is Rowid in SQLite?

The rowid column is a key that uniquely identifies the rows in the table. Tables that have rowid columns are called rowid tables. If a table has the primary key that consists of one column, and that column is defined as INTEGER then this primary key column becomes an alias for the rowid column.

Is SQLite case insensitive?

The default configuration of SQLite only supports case-insensitive comparisons of ASCII characters. The reason for this is that doing full Unicode case-insensitive comparisons and case conversions requires tables and logic that would nearly double the size of the SQLite library.

How many Autoincrement columns are allowed in a single table?

You can't have two auto-increment columns.
