Placeholder for a report

Question

I need to create a report. the report will be able to create a column (which is not in the database) to assign values associate with a field from database.
my example is:
field 1 ( which is the one from database)
report letter ( which is the one out of database but created on the report)
condition:
when field 1 is the range of '00 - 25', report letter is assigned as 'A'.
when field 1 is the range of '26 - 30', report letter is assigned as 'B'
and so on.
can oracle report do that? and how?

Answer 1

The problem you're hitting here is that you can't create a break group on only a formula column. To do what you're after, you need to modify the SQL to create the required values rather than using a formula column. You can then move the SQL column into a break group and add a summary column to it.
eg:
select 'A' ReportLetter
,field2
,field3
from tableName
where field1 between 0 and 25
union
select 'B' ReportLetter
,field2
,field3
from tableName
where field1 between 26 and 30
union
select 'C' ReportLetter
,field2
,field3
from tableName
where field1 > 30
You can then drag "ReportLetter" into a break group and add an appropriate summary column to it.
