Combine rows when the end time of one is the start time of another (Oracle)

Question

I just can\'t seem to get this query figured out. I need to combine rows of time-consecutive states into a single state.

This question is similar to the question fou

Answer 1

You can do that with a recursive query (something with CONNECT BY / PRIOR in oracle, IIRC) I did the same thing for Postgres in this thread : Get total time interval from multiple rows if sequence not broken

It might need a bit of reworking to make it fit into the oracle syntax.
