Getting "invalid identifier" error while inserting dynamic date value in table

Hi,

I am creating a script wherein I am trying to fetch "PASSWORD_CHANGE_DATE" & LAST_LOGIN details of user via dba_users view into an table. This script will run via tool to print the details in csv file.

Now while running this part of script I am getting error:

declare 

  TYPE LoginRecTyp IS RECORD (

   USERNAME VARCHAR2(200),

   last_login DATE,

   password_change_date DATE

);

  TYPE LoginList IS TABLE OF LoginRecTyp;

  logins LoginList;

   begin

EXECUTE IMMEDIATE ('select USERNAME,last_login,password_change_date from dba_users where USERNAME in ( select name from sys.user$ where type# = 1 and EXPTIME is null)')
