How does SQLite database work? SQLite works by compiling SQL text into bytecode, then running that bytecode using a virtual machine. The sqlite3_prepare_v2() and related interfaces act as a compiler for converting SQL text into bytecode. The sqlite3_stmt object is a container for a single bytecode program that implements a single SQL statement.
