Table1                                                     Table2

mbr_id                                                      Claim
plan                                                        mbr_id

                                                            rc_code)
I need to select every row from Table1 and update Sel_type with a value
of "X" if Table2 has at least one ps_code in ('191', '192', '193') and the plan = 1
If the plan = 2   and rc_code  in ('A', 'B', 'C')    Sel_type = "X"

Hi,
Try this.

select a.mbr_id, a.plan, sel_type = (case when b.ps_code is null then null else 'X' end)
from Table1 a left outer join Table2 b
on a.mbr_id = b.mbr_id and ((a.plan = 1 and b.ps_code in ('191', '192', '193') )
                  or a.plan = 2 and rc_code  in ('A', 'B', 'C'))

Done some mistake with the code:
Try this one:

select a.mbr_id, a.plan, sel_type = (case when b.ps_code is null then null else 'X' end)
from Table1 a left outer join Table2 b 
on a.mbr_id = b.mbr_id and ((a.plan = 1 and b.ps_code in ('191', '192', '193') ) 
			or (a.plan = 2 and rc_code  in ('A', 'B', 'C')))
