![]() 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. So, for the second condition, for a new row, rowid = max(rowid) + 1. 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. Mind you, I'm only guessing here you may need to experiment a bit.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! use type int? yes, with the question mark). ![]() Maybe you need to make property ID nullable (i.e. Though it would be surprising that nobody else has ever ran into this. If that is not possible in SQLite-net (you may need a debugger here), then that may well be a bug. Make sure your INSERT statements do not contain an explicit value (other than NULL) for column ID, otherwise the column will not auto-increment. Longer answer: If you declare a column of a table to be INTEGER PRIMARY KEY, then whenever you insert a NULL into that column of the table, the NULL is automatically converted into an integer which is one greater than the largest value of that column over all other rows in the table, or 1 if the table is empty. (Please double-check whether column ID actually has type INTEGER PRIMARY KEY once the table has been created.) Short answer: A column declared INTEGER PRIMARY KEY will autoincrement. The problem was solved by removing AutoIncrement. The RENAME TO syntax changes the name of table-name to new-table-name. ![]() The ALTER TABLE command in SQLite allows these alterations of an existing table: it can be renamed a column can be renamed a column can be added to it or a column can be dropped from it. But apparently the code samples are wrong, considering this similar problem:Īndroid table creation Failure (near "autoincrement": syntax error)? SQLite supports a limited subset of ALTER TABLE. Nothing stupid about your code matches the code samples on alright. I tried leaving off AutoIncrement and it does not appear to increment the ID without it. Now when an attempt is made to create the Tables, I get "Syntax Error near AutoIncrement". SQLite AUTOINCREMENT Summary: in this tutorial, you will learn about SQLite AUTOINCREMENTcolumn attribute and when to use it in your table. I wanted to AutoIncrement the keys so I reconstructed the Tables like this: using SQLite I had my code working when I did not have AutoIncrement on my Primary Keys of the tables. It's me again, the guy working with SQLite-net. Autoincrement A description of the AUTOINCREMENT keyword in SQLite, what it does, why it is sometimes useful, and why it should be avoided if not strictly necessary.
