How to check which views are not read only

Question

Hi, I need to run a script in order to get the views that were not created with the read only option. Where can I get that info? It doesn't seem to be in dba_views.
Thanks and regards

Answer 1

Join it with DBA_CONSTRAINTS (CONTRAINT_TYPE = 'O') :
SYS@db102 SQL> select view_name, text from dba_views where owner = 'U1';
VIEW_NAME                      TEXT
V_EMP_RO                       select empno,ename,job from myemp with read only
V_EMP                          select empno,ename from myemp
SYS@db102 SQL> select view_name, decode(constraint_type,'O','RO','RW')
  2  from dba_views v, dba_constraints c
  3  where v.owner = c.owner(+)
  4  and view_name = table_name(+)
  5  and v.owner = 'U1';
VIEW_NAME                      DE
V_EMP_RO                       RO
V_EMP                          RW
SYS@db102 SQL>
