Using your C code, you can create an external function to SQLite which generates the new UUID. You can then have SQLite use this function when inserting a new row, or make the function a DEFAULT value for the column. <https://sqlite.org/c3ref/create_function.html> <https://stackoverflow.com/questions/7867099/how-can-i-create-a-user-defined-function-in-sqlite> <https://stackoverflow.com/questions/9035649/bitmask-grouping-using-sqlite> You can then do INSERT INTO MyTable VALUES (NULL, makeNewUUID(), 'Lenny') Or CREATE TABLE MyTable(id INTEGER PRIMARY KEY, uuid TEXT DEFAULT makeNewUUID(), name TEXT); (At least I think you can use external functions as defaults. Can’t check it right now.)
