Let's say I have a function that needs to collect some data from various
tables and process and sort them to be returned to the user.
In general, would it be better to create a temporary table in that
function, do the work and sorting there, and return it... or keep a
permanent table for pretty much the same thing, but add a "user session"
field and return the relevant rows from that and then delete them?
Sorry this is vague, I know it most likely depends on the workload and
such, but I'm just putting this together now. I could go either way, and
also switch it up in the future if necessary. Is there a rule of thumb
on this one? I'm a bit biased against temporary tables, but then again
if the normal table gets a lot of action it might not be the optimal choice.
Thanks and regards,
Stephen Cook
