Re: to pass a parameter

Sorry, but i made a mistake here !
the function dept or is equivalente coud not solve this problem (pass a
table name as a parameter)

In Oracle exist Dynamic SQL, is there something like that in postgres ?
Is it possible to execute a query built in a plpgsql function or do we
need to use Perl and the Pg module for exemple ?
