I want to get members btw the particular age group JOIN with the no of days they have been opened an account & their amount.In Oracle, use double-quotes (or nothing) instead of square brackets around aliases:
COUNT(DateOfBirth) * SUM(RPTInvHosp.AccountListAmount)  as "Calc"The double-quotes are only necessary if you want the alias not to conform to the normal naming conventions; they are optional around normal names, such as CALC.
There are no built-in functions called GETDATE or DATEDIFF in Oracle.
In Oracle, SYSDATE returns the current DATE (on the database server).
There's nothing very convenient in Oracle for getting the difference between two DATEs in units of a year. The best way is to use MONTHS_BETWEEN to get the difference in months, and then divide that number by 12, like this:
WHERE     FLOOR ( MONTHS_BETWEEN ( SYSDATE
                            , DateOfBirth
           / 12
           )          BETWEEN     0
                     AND     4Do you need help about how to do a join?
It's not at all clear what you want here.
Whenever you have a question, post CREATE TABLE and INSERT statements for your sample data, and post the exact results you want from that data. Explain, with specific examples, how you get those results from that data.
Always say what version of Oracle (or other software) you're using.
