The SQL queries to update database at install doesn't cope well with the AUTOINCREMENT field syntax on SQLite.
It uses:
cuc_id INTEGER NOT NULL AUTO_INCREMENT,
Database engine class will translate it to:
cuc_id INTEGER NOT NULL AUTOINCREMENT,
What SQLite expects is:
cuc_id INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT,
So we have this error:
Error: 1 near "AUTOINCREMENT": syntax error
