set Parameter default using SQL

HSMorales

Is there a way I can I set my parameter default using SQL ??

I have 2 input date parameters (Start_Date and End_Date) that are binded to a Dataset. The dataset is then displayed on my report.

I would like to set the default date to a date selected from a table such as:

"Select Max(PERIOD_END_DATE) from PERIOD_DATES where PERIOD_END_DATE < sysdate"

These parameters have a date picker so the user can also select a different date.


I am running BIRT 3.7.0
