Is it possible to get and remove something from a hash in Redis in one operation?

I'm currently using Redis and doing an HGET followed by an HDEL to remove the field (and its value) from the hash once I've retrieved the value I need (which only needs to be used once).

Is there any way to do this in one operation (i.e. get a field and remove it from the hash)? I skimmed through the docs and couldn't find the right command.

Transactions will do this. Use the MULTI command to start a transaction, within the transaction HGET what you want, HDEL it, and then EXEC.

You could also write a Lua script to do this.
