sqlite3_stmt *sqlite3_next_stmt(sqlite3 *pDb, sqlite3_stmt *pStmt);
This interface returns a pointer to the next prepared statement after pStmt associated with the database connection pDb. If pStmt is NULL then this interface returns a pointer to the first prepared statement associated with the database connection pDb. If no prepared statement satisfies the conditions of this routine, it returns NULL.
The database connection pointer D in a call to sqlite3_next_stmt(D,S) must refer to an open database connection and in particular must not be a NULL pointer.
