sqlite3_next_stmt —
Find the next prepared statement
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.
