I am going to wire a new room in a basement. There will be a dedicated
circuit for it. I want to have a switch to control wall lighting but
not control the wall outlets. Do I have to split the circuit before
the switch to do this or is there another easy way?

I would suggest more electrical knowledge before you tackle this.
If you were ready to do this sort of thing, that would not be a
question. Also, one ckt may not be enough; realize that a popped
breaker/fuse could put the whole place in darkness; does that
You could run the circuit to your switch box. Then run one non switched line
from there to the outlets and one switched line to your sconces. You could
run the circuit to all your outlets first, then up to your switch, then to
Or daisy chain all the outlets, and then the lights, with a switch leg down
to the wall switch before the first light. Lots of ways to do it, and we
can't see the room, or the load, from here.
But having said that, I agree with the other posters- having to ask the
question means OP needs to read the DIY book at a minimum, and preferably
pay for some expert help. Local code and practicality often dictate that the
lights and outlets be on different strings, assuming there is an open hole
in the service panel to do so. How many lights? How many outlets? What will
the loads be? If this is a 'man cave' TV room, there should be a string just
for those outlets. If this is a workshop with power tools, you definitely
need multiple outlet strings. Add up all the loads of each type, plus 25%
headroom, and work backward to the wiring design. If there will be any
siginificant loads, better to split the new work across both sides of the
panel, for load balancing. I'm no electrician- I know just enough to be
dangerous. Anything more than 1 for 1 device replacement, I look it up or
ask an expert.
I don't know if the code would allow you to split off to the light and other
outlets in the switch box, but as a practical matter you dont have much
space in the switch box to do this. I would split off in a junction box
that remains accessable after the contruction.
However there are a number of options that will depend on the situation.
I have to agree with Pop. You need more information than can be given on
the newsgroup. At the minimum I suggest buying a book or getting one from
the library covering basic home wiring. There are just too many things that
need to be done to assure a safe legal job to handle here.
Sounds like you need more help than the group can offer you if you are
having problems with this simple task.
Easiest way to do what you are trying to do would be to run from the circuit
box to the outlet(s) then to the light switch as the last thing on the leg.
Keep ni mind though that with the entire room on one circuit the whole room
will go dark if the breaker pops.
