Dynamic Sql in stored Procedure - forum topic by choppadandi

Hello ALL,
 
Is it possible to give host variables in slection list in dynamic sql in stored procedure.
For ex: select :Col1 , :Col2  from :database.tablename  where source_system = : col3'
 
for our process have to fetch from different cols from same table  based on source_system  and from different databases , table names are same.
