Edit Question
Title
Body
I tried this: from Table where (:par1 is null or col1 = :par1) but it happens that from Table where :par1 is null always returns all the rows of the table, even if the :par1 is not null. while select * from table where col1 = 'asdf' does not return any row. I can't use native grammars because my application is supposed to run on different database engines
