int sqlite3_reset(sqlite3_stmt *pStmt);
The sqlite3_reset() function is called to reset a prepared statement object back to its initial state, ready to be re-executed. Any SQL statement variables that had values bound to them using the sqlite3_bind_*() API retain their values. Use sqlite3_clear_bindings() to reset the bindings.
If the most recent call to sqlite3_step(S) for the prepared statement S returned SQLITE_ROW or SQLITE_DONE, or if sqlite3_step(S) has never before been called on S, then sqlite3_reset(S) returns SQLITE_OK.
