In your case, you're gonna want to take a look at the NODE_CHECKPOINTS table, you can query it by flowid.

Just try it with the corda shell if you're looking just once.

Here's a breakdown of each of the tables in corda and what is contained in all of them.

If you want to do it programmatically take a look at the docs page on vault queries :

good luck
