Home -> Community -> Mailing Lists -> Oracle-L -> Re: How to put a TOP 1 in a select
Your english is fine, lets see if I understand the query...
Does it return the Item and Trans_Date of the record with the smallest quantity (ie: first row returned given that query is ordered by quantity)?
Oracle (at least version 8 - not sure about 9) doesn't really support this SQL but there are workarounds:
select * from (select item, trans_date
where company = 2000 and trans_date between (sysdate-14) and sysdate
and doc_type = 'IS'
and reason_code = 'VTCL'
and substr(item, 2,2) = '57'
order by quantity)
where rownum <= 1;
This will probably return the correct result if I have understood the meaning of TOP 1 properly. Performance may or may not be an issue - although depending on how SQL Server implements this query you may not see much difference.

Hi!!
I was working with SQL Server 2000, and now the company decided to change
to Oracle. So I don't know much about Oracle, I am just reading a book and
try to find information on the net.
I am trying to do the next query, but I guess Oracle did not have the
function TOP. How can I do a TOP 1 in Oracle?
select TOP 1 ITEM, TRANS_DATE from ICTRANS where
(COMPANY = 2000)
AND (TRANS_DATE BETWEEN (CURRENT_DATE-14) AND CURRENT_DATE)
AND (DOC_TYPE = 'IS') AND (REASON_CODE = 'VTCL') AND (SUBSTR(ITEM, 2, 2) = '57')
I hope you undestand my English.
