Oracle query to pick the proper record with Join and Inner query
0
I need a condition to write the query in oracle to satisfy below condition
A and B are 2 tables
- A will have copy of B not true all the case
- In A I will have 2 records if override is 'Y' . one is for override as 'N' and override as 'Y' and onevale can be same or not
- For B we can have the same as 'Y' or 'N' for override but I need the latest can retrieve using indx where it is a primary key(latest
pk) - In A override can be 'Y' then it will check with latest override of B to find there is a change on onevale
- If A override can be 'N' but it should compare the latest override of 'Y' in 'B' to find there is a change on onevale
- If onevale is same and if override is same then no record should display
select *
From A A1, B B1
Where A1.SS = B1.SS
And A1.TS = B1.TS
and a1.indx = (select max(indx)
from A
where tc = 'T1234'
and sc = 'S1234'
)
and A1.override = B1.override
and (a1.onevale <> b1.onevale)
Can some one explain this query will satisfy all the condition

You have data, we don't. So, what happens when you run the query? Does it return a desired result? If so, then it works. If not, you'll have to fix it. You mentioned some "Y" and "N", but I don't see any in code you posted. I presume that test case might help the community help you. Consider posting it.
