![]() If the AUTOINCREMENT keyword appears after INTEGER PRIMARY KEY, thatĬhanges the automatic ROWID assignment algorithm to prevent the reuse of ROWIDs over the lifetime of the database. This is true regardless of whether or not the AUTOINCREMENT CREATE TABLE CSSATRULES ( id integer NOT NULL PRIMARY KEY AUTOINCREMENT, cssversion varchar(10) NOT NULL, syntaxid integer NOT NULL ). 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. In SQLite, a column with type INTEGER PRIMARY KEY is an alias for the ROWID (except in WITHOUT ROWID tables) which is always a 64-bit signed For example, a numeric primary key in SQL Server is automatically set up to be an IDENTITY column. How do I create an AUTOINCREMENT field What datatypes does SQLite support SQLite lets me insert a string into a database column of type integer Why doesn't SQLite allow me to use '0' and '0. 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. The AUTOINCREMENT keyword imposes extra CPU, memory, disk space, andĭisk I/O overhead and should be avoided if not strictly needed. For non-composite numeric and GUID primary keys, EF Core sets up value generation for you by convention. The AUTOINCREMENT keyword imposes extra CPU, memory, disk space, and disk I/O overhead and should be avoided if not strictly needed. Here is what official SQLite documentation has to say on the subject (bold & italic are mine): ![]()
