Question

Hello,
I am using BO XI R2 and I come to an issue with LOV. Can LOV be used as a key-value list?
Say I have a key-value list as below:
A --> 1
B --> 2
Can LOV just list 'A, B.. ' and return 1 if user choose A and 2 if user choose B?
Many thanks.

It is possible only if you know all possible KEY values:
with t as (
           select 1 id,'STATUS' key,'TRUE' val from dual union all
           select 1,'AGE GROUP','10' from dual union all
           select 1,'TRAVEL','Y' from dual union all
           select 2,'STATUS','FALSE' from dual union all
           select 2,'AGE GROUP','20' from dual union all
           select 2,'TRAVEL','N' from dual
select  id,
        max(case key when 'STATUS' then val end) status,
        max(case key when 'AGE' then val end) age,
        max(case key when 'AGE GROUP' then val end) "AGE GROUP",
        max(case key when 'TRAVEL' then val end) travel
  from  t
  group by id
        ID STATUS AGE   AGE GROUP TRAVEL
         1 TRUE         10        Y
         2 FALSE        20        N
SQL> If you are on 11g, you can use PIVOT construct, but again you need to know resulting columns upfront.
Another thing you could do is to return a CSV list of key all values in one column using STRAGG (or LISTAGG if you are on 11.2), hierarchical queries, XML or undocumented WM_CONCAT.
