    What is your MySQL server version ? Is there any Primary key in your table ? Without that we really cant define "order", as data is unordered

  • This looks like a gaps and islands problem to me, or at least a variant of it. If you are using MySQL 8+ or later, then you may take advantage of analytic functions, which would really help here.
