Re: Views inside views, execution plan & external WHERE clause

You want to:

1. Filter complex data
2. Join single results

and it does:    

1. Join complex data [Quoted]
2. Filter complex result

You can create a package with some global variable, e.g.:

 gv_employee_id NUMBER

and Function  

 Get_Employee_ID
  Return gv_employe_id;

and a procedure

 Set_Employee_ID (p_value IN NUMBER)

In your query, view, you could have a filter in the "deepest" WHERE:

...
[Quoted]  WHERE employe_id=(SELECT My_Package.Get_Employee_ID FROM DUAL)

Before you execute the query you just set employee id via

Set_Employee_ID

so it does what you want:

1. Filter complex data
2. Join single results
