PREPARE_PERSISTENT top-level constant

int const PREPARE_PERSISTENT

The SQLITE_PREPARE_PERSISTENT flag is a hint to the query planner that the prepared statement will be retained for a long time and probably reused many times.

Without this flag, sqlite3_prepare_v3() and sqlite3_prepare16_v3() assume that the prepared statement will be used just once or at most a few times and then destroyed using sqlite3_finalize() relatively soon. The current implementation acts on this hint by avoiding the use of lookaside memory so as not to deplete the limited store of lookaside memory. Future versions of SQLite may act on this hint differently.
