Hello All Good Evening,
create table deltavalues (planid varchar(10), baseval float, highval float)
Insert into deltavalues values ('1002', 2000,5000)
Insert into deltavalues values ('1003', 1000,0)
Insert into deltavalues values ('1004', 500,0)
Insert into deltavalues values ('1005', 1000,2000)
--I have below query , basically getting emnployee table balance between deltavalues table baseval column and highval column
select * from employee e join deltavalues d on e.planid = d.planid
where e.balance between d.baseval and d.highval
but here what i am requesting you is how can i change the highvalue to not include if it is 0
for example above example plan 1003, 1004 has highbal as 0 so i want to write a query to get employee data between 1000 and anyvalue (> 1000 - no limit)
same way for 1004 between 500 and no end values (infinity)
please advise me in some smart way of doing rather than case statement, if possible please
how can i write that ?
please advise
Thank you in advance
Milan

SELECT *
FROM employee e
JOIN deltavalues d
ON e.planid = d.planid
WHERE e.balance BETWEEN d.baseval AND
CASE d.highval
WHEN 0 THEN 999999 -- or whatever higher number you need
ELSE d.highval
END
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
