SQL script to return only one row per persnbr

slightwv,

Your solution seems to work the best seeing as though I have multiple columns from multiple tables.  Can you help me get your query into my existing query.  Basically it goes like this.

Your Query Modified:

select cardnbr, currentstatus, idnbr, datelastmaint from
(
select cardnbr, currentstatus, idnbr, datelastmain, row_number() over(partition by cardnbr order by idnbr desc) myrownum from cardissue
) where myrownum=1

Exisitng Query to Combine With

select a.cardnbr, b.accountnbr, c.persnbr, d.currentstatus, e.accountstatus, e.office, e.phone
from card a, cardpers b, pers c, cardissue d, account e
where a.cardnbr=b.cardnbr and b.persnbr = c.persnbr and b.cardnbr=d.cardnr and b.accountnbr=e.accountnbr and b.cardtype<>'CARD'

>>Exisitng Query to Combine With


Where is idnbr in that query?

Anyway you should just be able to take what you have and add the row_number function call using the proper columns in the query.

The idnbr would be in the cardissue (d) table.  I don't really need it in the output I just want the record with the highest value.

Untested (just typed in):

select cardnbr, accountnbr, persnbr, currentstatus, accountstatus, office, phone from (
select a.cardnbr, b.accountnbr, c.persnbr, d.currentstatus, e.accountstatus, e.office, e.phone, row_number() over(partition by  c.persnbr order by d.idnbr) myrownum
from card a, cardpers b, pers c, cardissue d, account e
where a.cardnbr=b.cardnbr and b.persnbr = c.persnbr and b.cardnbr=d.cardnr and b.accountnbr=e.accountnbr and b.cardtype<>'CARD'
)
where myrownum=1

I was able to get that to work.  Thank you very much.

Glad to help.
