The lastinsertrowid () SQL function is a wrapper around the sqlite3lastinsertrowid () C/C++ interface function. 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 integer. Var db = LocalStorage.openDatabaseSync("Kardex", "1.0", "Kardex", 1000000) As the SQLite documentation says: The lastinsertrowid () function returns the ROWID of the last row insert from the database connection which invoked the function. So, if you closed the connection with which you did the last insertion and run the query with another connection you will not get the rowid of the last row inserted. Here some query from my project with qt example JS style: function dbInitflightlog() the ROWID of the last row insert from the database connection which invoked the function. INSERT INTO TABLENAME VALUES (value1,value2,value3. The SQLite INSERT INTO syntax would be as follows. And how Last Insert Rowid works. However, make sure the order of the values is in the same order as the columns in the table. In order to maximize concurrency, SQLite works to minimize the amount of time that EXCLUSIVE locks are held. I found in SQLite the vacuum query but I don't have any idea how to use it, not example are corresponding to qt example javascript. You may not need to specify the column(s) name in the SQLite query if you are adding values for all the columns of the table. If I delete the third, I have rows: 1,2,4 but I want to refresh rowid to got 1,2,3, how do than? Rowid is auto increment but when I delete one row, I have missing Row id.Įxemple if I insert 4 rows, Id go from 1 to 4 with 1,2,3,4. I'm using example of local storage from QT and I would like to know how can I have Id cleaned aftern delete or insert.
