Re: PL/SQL and SQL Navigator

Pavel,

in the SQL*Navigator, can't you just wrap your PL/SQL script below into the begin end:

begin
  if exists (select 1 from user_tables where table_name='C_POLOZ') then   begin

      select 1 from dual;
  else

      select 2 from dual;
  end if;
end;

and then run it? -this is a standard anonymous PL/SQL block of code.

cheers,

Jørgen
