what is dynamic sql?
and what is difference between sql and dynamic sql?

Dynamic sql is code that is not compiled until run time whereas normal sql is compiled at compile time.

suppose you want to attach an external table definition to file that has not shown up yet. well you cant create the external table until you know what the filename is (suppose it has a datetime stamp in the name or something) and you cant compile a select statement against a table that doesnt exist yet... there for you need to do it at run time.
