I have a table called table1 with the following fields:
itemno, podate, rate
I want to find the latest podate and highest rate for the given item (say 1). I have a solution for this below.
Is there any way to improve this query and here I used itemno=1 four times. Please help.
Query:-
-----
SELECT *
FROM Table1
WHERE itemno=1
and podate in (select max(podate) from table1 where itemno=1)
and rate in (select max(rate) from table1 WHERE itemno=1 and podate in (select max(podate) from table1 where itemno=1))
