Not essential. You can do this with a DSQL statement and a couple of correlated subqueries:

ClientInfo:Client_ID PhoneNumber --> PersonInfo:Client_ID,
PersonType=0, PhoneNumber

update PersonInfo pi
set pi.PhoneNumber =
(select ci.PhoneNumber from ClientInfo ci
where ci.Client_ID = pi.Client_ID)
where pi.PersonType = 0
and exists (select 1 from ClientInfo ci1
where ci1.Client_ID = pi.Client_ID)

Note: you won't need the existence check if your PersonType = 0 criterion is actually the way you have recorded the fact that a corresponding ClientInfo record exists.
