Question
Runtime Parameter in Report Builder
Hi there folks,
I was wondering if we can have the option of choosing at runtime from the report builder parameter so that if the end-user selects 'Yes' then the report will run one specific query and if he chooses 'No' then another particular query is invoked. What I mean to say that by choosing between Yes and No at runtime one should have the option of returning query results based on the same table but having different columns selected via the SELECT statement.
Thanks in advance

I just re-read your question and realized that you were talking about changing the actual columns selected. In that case, the first option I listed would not work but the second option would.
One more option is to use a Lexical reference. Here is an example from Reports Help:
SELECT &P_ENAME NAME, &P_EMPNO ENO, &P_JOB ROLE FROM EMP
P_ENAME, P_EMPNO, and P_JOB can be used to change the columns selected at runtime. For example, you could enter DEPTNO as the value for P_EMPNO on the Runtime Parameter Form. Note that in this case, you should use aliases for your columns. Otherwise, if you change the columns selected at runtime, the column names in the SELECT list will not match the Report Builder columns and the report will not run.

There are a few ways to do this.
One way is to code it into your select like:
select *
from my_table
where id = ....
AND
( (p_my_parameter = '1'
AND join1 = ...
)
OR
(p_my_parameter = '2'
AND join2 = ...
)
)
Another way is to simply create both select statements, create 2 separate layouts, then put a trigger on each of the layouts. One trigger (based on what the parameter is) will return TRUE and the other will return FALSE so only one layout/select will actually be visible.
