Updating multiple records

Question

Hi,
Im having issues with updating multiple records.
This query selects users in a specific unit that are inactive (ui.nf_statusid = 2) and compare it newsmail_recipient table
select *
                    from roleuser ru, unit u, userinfo ui
                    where u.ip_unitid = ru.nf_unitid
                    and u.ip_unitid = unit_id
                    and ui.ip_userid = ru.nf_userid
                    and ui.nf_statusid = 2
                    and n_internal = 0
                    and ui.ip_userid  in (select user_id
                                               from newsmail_recipient
                                              where user_id = ui.ip_userid
                                                and nf_listid = liste
                                                and nf_statusid = 1;the second script will set the users to inactive in newsmail_recipient that are inactive in the userinfo table.
update newsmail_recipient
             set nf_statusid = 2
              , d_modified = sysdate
             where user_id = ui.ip_userid;I would like to know if its possible to merge this query. I know its possible for insert but havent tried update before.
This is how i do it, but its not working.
case when (select *
                    from roleuser ru, unit u, userinfo ui
                    where u.ip_unitid = ru.nf_unitid
                    and u.ip_unitid = unit_id
                    and ui.ip_userid = ru.nf_userid
                    and ui.nf_statusid = 2
                    and n_internal = 0
                    and ui.ip_userid  in (select user_id
                                               from newsmail_recipient
                                              where user_id = ui.ip_userid
                                                and nf_listid = liste
                                                and nf_statusid = 1)
        then update newsmail_recipient
             set nf_statusid = 2
              , d_modified = sysdate
             where user_id = ui.ip_userid;
        end;thanks guys...

Table structure:
newsmail_recipient:
IP_RECIPIENTID     NUMBER(8,0)
NF_LISTID             NUMBER(8,0)
NF_STATUSID     NUMBER(8,0)
D_CREATED     DATE
D_MODIFIED     DATE
C_NAME             VARCHAR2(100 CHAR)
C_EMAIL             VARCHAR2(256 CHAR)
USER_ID             NUMBER(10,0)
NEWSMAIL_ID     NUMBER(10,0)userinfo:
IP_USERID             NUMBER(10,0)
NF_STATUSID     NUMBER(10,0)
N_INTERNAL     NUMBER(1,0)@jeenesh:
I tried your query but i get this error:
Error(510,30): PL/SQL: ORA-00904: "UI"."IP_USERID": invalid identifierJust wondering why, but ui.ip_userid is declared.
Actually, this is a package script.
