No, they are not.

Hi all,
From application’s standpoint, it seems using CTE saves a lot work. You no longer need to parse values out only to pass them back in, and only one round-trip to the db server.
If I’m not wrong, CTE is equivalent to serializable transactions? So I guess the downsize is that quarries can’t be run in parallel?
I do not think a CTE changes the isolation level.
If I decide to replace all my transaction code with CTE, will I shoot myself in the foot down the road?
