sql update - Updating Multiple Columns from another table - Need Oracle format -

-

i have script use in sql server need convert oracle format. can help?

    update persons p set          p.jobtitle=te.jobtitle,         p.last_name=te.last_name,         p.first_name=te.first_name,         p.dblogin_id=te.dblogin_id,         p.email_id=te.email_id,         p.userlevel=te.userlevel,         p.facility_id=te.facility_id,         p.supervisor=te.supervisor,         p.department=te.department,         p.winloginid=te.winloginid    temp_ecolab_persons te    p.person=te.person;

--from article below came following statement. still doesn't work unfortunately:

  update (select p.jobtitle, p.last_name, p.first_name, p.dblogin_id, p.email_id,         p.userlevel, p.facility_id, p.supervisor, p.department,         te.jobtitle, te.last_name, te.first_name, te.dblogin_id, te.email_id,         te.userlevel, te.facility_id, te.supervisor, te.department      persons p, temp_ecolab_persons te p.person=te.person)   set       p.jobtitle=te.jobtitle,      p.last_name=te.last_name,      p.first_name=te.first_name,      p.dblogin_id=te.dblogin_id,      p.email_id=te.email_id,      p.userlevel=te.userlevel,      p.facility_id=te.facility_id,      p.supervisor=te.supervisor,      p.department=te.department;

this how it. might not best performance, works.

merge persons_tmp pt using (      select p.person, p.job_title, p.first_name, p.last_name, p.facility_id      persons p) tmp on (pt.person = tmp.person) when matched  update set      pt.facility_id = tmp.facility_id,      pt.job_title = tmp.job_title,     pt.first_name = tmp.first_name,     pt.last_name = tmp.last_name;

the script above update information in persons_tmp table using data persons table. believe in case, want other way around. so, please make sure make necessary changes before running script.

you can add "when not matched then.... " clause above sql in case need insert new records, if not exist.
