Does Rowid change in SQLite?

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.

Does SQLite reuse ids?

Only ROWID values from previous transactions that were committed are considered. ROWID values that were rolled back are ignored and can be reused. SQLite keeps track of the largest ROWID using an internal table named "sqlite_sequence".

Does SQLite have auto increment?

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.

Is Rowid same as primary key?

The true primary key for a rowid table (the value that is used as the key to look up rows in the underlying B-tree storage engine) is the rowid. The PRIMARY KEY constraint for a rowid table (as long as it is not the true primary key or INTEGER PRIMARY KEY) is really the same thing as a UNIQUE constraint.
