I'm stuck on this for days now. I have 3 fields, tot_order, slsnum and ordernum. I need to get the max value in ordernum, which is a unique field and its total order number in the ordernum field. The slsnum field is based on a date, so I could have a slsnum# 18443450 repeatedly per row.
tot_order: 240, 100, 50
ordernum: 23006343, 220110021, 180872124
I need the end result like this: tot_order: 240 slsnum: 18443450 ordernum: 23006343
You can use a correlated subquery for this:
SELECT tot_order, slsnum, ordernum
FROM table as t1
WHERE ordernum = (SELECT max(ordernum) FROM table as t2 WHERE t2.slsnum = t1.slsnum)
That subquery in the WHERE
clause references the slsnum
field in the main query to grab the max(ordernum)
.
You can do this with the following query:
Select tot_order, slsnum, ordernum
from table as t
where ordernum>=ALL(
Select ordernum from t
)
Give this a whirl..
SELECT tot_order, slsnum, ordernum
FROM YourTable
WHERE OrderNum = (SELECT Max(OrderNum) FROM YourTable)
SELECT *
from table_name
where ordernum = (
select max(ordernum) from table
)
