View with parameter

Question

Is there any way to set parameter in view.

Answer 1

Depending on the goal of passing parameters to a view, you can potentially use a context, as I discussed earlier...
SCOTT @ nx102 Local> create package ctx_package
  2  as
  3    procedure set_parameter( p_param IN VARCHAR2 );
  4  end;
  5  /
Package created.
Elapsed: 00:00:01.92
SCOTT @ nx102 Local> create package body ctx_package
  2  as
  3    procedure set_parameter( p_param IN VARCHAR2 )
  4    as
  5    begin
  6      dbms_session.set_context( 'MY_CONTEXT', 'PARAMETER', p_param );
  7    end;
  8  end;
  9  /
Package body created.
Elapsed: 00:00:00.11
SCOTT @ nx102 Local> create context my_context using ctx_package;
