trying include "[all]" option list of dynamic field values in dynamic parameter. read should try using database commands this. implemented command saw on internet:

select sea_epps_main. "org_unit" emsdba.sea_epps_main union select '[all]' emsdba.sea_epps_main

however, when run (i have 3 commands since want [all] included on 3 parameters report uses), massively duplicated records.

i know off sql command, can't find clear example of needs to behave properly.
