Unknown opcode or table/row not found

SQLITE_NOTFOUND (12) is used internally by SQLite and by virtual table implementations. In user-facing contexts it appears when sqlite3_vtab_on_conflict() is called outside a conflict handler, or when a requested table or element is not found by an extension.

1. 1Virtual table xUpdate method could not locate a row.
2. 2sqlite3_vtab_on_conflict() called outside of an ON CONFLICT handler.
3. 3Extension or custom VFS reporting a missing resource.

Virtual table implementations and some SQLite C extension APIs.

-- SQLITE_NOTFOUND is rarely exposed to SQL users directly
-- Typically seen in C extension code:
-- if (sqlite3_vtab_on_conflict(db) == SQLITE_NOTFOUND) { ... }

Surfaced as OperationalError in drivers when a virtual table cannot locate a row.
