![]() ![]() I don't know if this helps, as I don't know what you are attempting to do with nr, but maybe it will. Also, when you insert a new row, you can get the rowid assigned by SQLite using "SELECT last_insert_rowid()". You can access the rowid of any row directly as "rowid", "_rowid_" or "oid". The sole purpose of autoincrement in SQLite is to not reuse previously used record numbers (whether they have been deleted or not). In the first case, SQLite tracks maxrowid over the life of the database, and any new record is assigned maxrowid + 1 where maxrowid is the maximum rowid ever seen. If the AUTOINCREMENT keyword appears after INTEGER PRIMARY KEY, that changes the automatic ROWID assignment algorithm to prevent the reuse of ROWIDs over. exec(create table person(id INTEGER PRIMARY KEY AUTOINCREMENT,namevarchar(20))). So, for the second condition, for a new row, rowid = max(rowid) + 1. im implementing a routine that reads row data from SQLITE db. If you don't use autoincrement, then SQLite assigns a rowid that is one higher than the current max rowid in use. Hi Glenn, as I understand it, autoincrement always chooses a number that is one higher than the highest rowid ever used in the database. Change it to INSERT INTO child (e, f, g) VALUES (1, 1, 3) and it works. ![]() incrementvalue Mention the value by which we would like to increment the key for the subsequent record. Here, startingvalue Mention the starting value we would like to use. Your inserts are failing because there is no row (a, b) with values (1, 2). SQL Server Auto Incrementauto-increment: In SQL Server, IDENTITY (startingvalue, incrementvalue) is used for the auto-increment feature. Your code works as expected in that I see the change of value in `sqlite_sequence`.`seq`, but the autoincrement of the database stubbornly refuses to update! The AUTOINCREMENT keyword imposes extra CPU, memory, disk space, and disk I/O overhead and should be avoided if not strictly needed. ![]()
