Dear All,
How are you doing? After a long time I am back again because I need help from you all expert. Please advise me, my queries is given below.
I have a table with employee_name which contain the field name empFirstName, empLastName, empAges, empMinExp, empMaxExp, empCTC. Etc. The employee can only select only number with out any fraction value. Like 1, 2,3, 4,5 etc. So, the problem is that when I want to fetch result by parameter min and max value of the employee I am not able to fetch the exact result. Eg.
John Peru1 24 yrs Min: 1 yrs Max: 3 yrs 2Lacs
John Peru2 24 yrs Min: 1 yrs Max: 3 yrs 2Lacs
John Peru3 24 yrs Min: 1 yrs Max: 3 yrs 2Lacs
Kin Kum 25yrs Min: 3 yrs Max: 5 yrs 3Lacs
Dem Fu 23yrs Min: 2yrs Max: 3 yrs 4Lacs
If, I want fetch the employee which are having minimum experience 1yrs upto 3 yrs of experience. I write the query as below,
Select * from employee_name where empMinExp> 1 and empMaxExp<=3
but here the query also fetch employee who entered minimum experience as 3 yrs. So, I am not able to get the exact result as per my query. Please help me in resolving the solution. Thanking you in advance for you kind cooperation and supports.

Don't you have something basically wrong with your table structure? What do the two columns mean, empMinExp and empMaxExp? Shouldn't this instead just be one column which states the employee's experience? Why would you store an minimum and maximum value for the employee?
A database is very powerful to deal with the data from our real world problems, and the database is most efficient and easiest to use when it's table structure correctly models our real world problem.

Thanks for the reply and suggestion. I really thank for the advice and I will take care from next time. But in the present scenario, what should be query, so that I can fetch only those employee which are having 1-3 yrs of experience not 3-5 yrs. please guide me.

Could you please post what you have tried so far?
I am afraid I don't understand where you are having problems.
Let us take this example:
One employee enters 1 for minimum experience and 3 for maximum experience.
Another employee enters 3 for minimum experience and 5 for maximum experience.
And you want a query that only selects the first person but not the second?
Then the query would be
Select * from employee_name where empMinExp> 1 and empMaxExp<=3
This would not select the second employee above because the query states that the "empMaxExp" field must be <= 3, and the second employee above has empMaxExp = 5.
But the Select query above is exactly the same that you showed in your original post.

Hi!
I'm writing a program that interacts with a db2 database through jdbc.
I frequently need to run a quite query q1 that involves several full
outer join of a table with itself. Once q1 is executed I need to
postprocess the result. This postprocessing involves several queries on
the result of q1. I think that the best solution would be to
materialize the result of q1 in the database. How can I do it?
Thanks a lot in advance!
