INSERT INTO salespeople (first_name, last_name, commission_rate) VALUES ('Fred', 'Flinstone', 10. INSERT INTO salespeople VALUES (null, 'Fred', 'Flinstone', 10.0) Ī second way is to define the fields you want to insert in your query, intentionally skipping the autoincrement field, like this: One way is to specify a null value for the SQLite autoincrement field, like this: A unique index will allow a NULL a primary key constraint wont. Table names that begin with 'sqlite' are reserved for internal use. UNIQUE INDEX alone doesnt have the same effect as PRIMARY KEY. The docs are correct, you just misinterpreted the behavior of SQLite and Peewee in this case. The AUTOINCREMENT keyword imposes extra CPU, memory, disk space, and disk I/O overhead and should be avoided if not strictly needed. In order to save CPU and RAM with SQLite, Peewee uses the native rowid field rather than specifically requiring globally unique auto-incrementing ids with SQLite. Every CREATE TABLE statement must specify a name for the new table. Peewee does create an auto-incrementing primary key field named 'id' automatically. Whether the table is subject to strict type checking.

Whether the table is a WITHOUT ROWID table. Optionally, a generated column constraint. When you have a database table with a SQLite autoincrement field, there are two ways to insert data into that table and automatically increment the primary key. SQLite supports UNIQUE, NOT NULL, CHECK and FOREIGN KEY constraints. Inserting data with a SQLite autoincrement field The keyword AUTOINCREMENT can be used with INTEGER field only. Declare the column type as INT instead of INTEGER. So the easiest ways to disable it are: Declare the column as UNIQUE instead of PRIMARY KEY. We can auto increment a field value by using AUTOINCREMENT keyword when creating a table with specific column name to auto increment. 2 Answers Sorted by: 9 Autoincrement behavior applies only to columns declared as INTEGER PRIMARY KEY. Here’s what this SQLite autoincrement syntax looks like in a complete SQLite database table definition: SQLite AUTOINCREMENT is a keyword used for auto incrementing a value of a field in the table. You can create it explicitly with the AUTOINCREMENT keyword. You can create a UNIQUE INDEX which has essentially the same effect as a PRIMARY KEY.

There are a couple of ways you can create an AUTOINCREMENT column: You can create it implicitly when you define the column as INTEGER PRIMARY KEY. You define a SQLite autoincrement field (also known in other databases as a serial, identity, or primary key field) with this syntax: In SQLite, an AUTOINCREMENT column is one that uses an automatically incremented value for each row that’s inserted into the table.
