The basic usage of AUTOINCREMENT keyword is as. The keyword AUTOINCREMENT can be used with INTEGER field only. We can auto increment a field value by using AUTOINCREMENT keyword when creating a table with specific column name to auto increment. Following is the query which we used to create Persons table without AutoIncrement column. SQLite AUTOINCREMENT is a keyword used for auto incrementing a value of a field in the table. Now we will see with examples of creating table in SQLite with and without AutoIncrement columns. Example of SQLite Table without AutoIncrement Suppose, in SQLite when we create a table without specifying AUTOINCREMENT option on a column then SQLite automatically creates the ROWID column to identify table rows uniquely within the table. It does so until I change the default int type for INTEGER, and that works, seems for some. Of course, this changes the language syntax a bit so I am not sure how big a change it would be in the lexer/parser etc. Generally, the auto increment property in SQLite can only work with numeric data types and its very useful to use with primary key constraints because primary key will always allow only unique values. SQLite - AUTOINCREMENT is only allowed on INTEGER PRIMARY KEY. The AUTOINCREMENT keyword can be used with INTEGER PRIMARY. > UPDATE t1 SET id rowid-1 WHERE rowid new. In SQLite if we set auto increment property on column it will generate sequential unique numeric values automatically whenever we insert a new record or row in the table. The SQLite AUTOINCREMENT is a keyword used for auto incrementing a value of a field in the table. AUTOINCREMENT fields and my field is not AUTOINCREMENT so sqlitesequence is never created. Here we will learn SQLite auto increment with examples and how to use SQLite auto increment property with column to generate unique values while inserting data with example.
