For this to happen, declare the Id column as either ROWID or INTEGER PRIMARY KEY. The reason for there being no autoincrement for the SQLite would be good note in documentation so we know what going on It is very confusing when the documentation say 'Because we have not specified a primary key, peewee will automatically add an auto-incrementing integer primary key field named id. This specific syntax will have sqlite to not substitute itId for rowid, so you will have both a separate autoincremented rowid column and your itId column. A solution is to change itId from integer primary key to int primary key. The following shows how to define a UNIQUE constraint for a column at the column level: CREATE TABLE tablename (. when working normally with the database, you can ommit the Id in INSERTs and SQLite will generate one for you. Primary key not unique in SQLLite with AutoIncrement. 1 Answer Sorted by: 0 It seems that substitution of null with a new rowid happens before the conflict is evaluated. Only at the table level, you can define a UNIQUE constraint across multiple columns.your original IDs will be preserved when the database is being rebuilt by using INSERT commands and explicitly specifying the Id!. ![]()
