Passing multiple parameters in sql query

Question

Hi All,
This may not be the correct place to post this.
How to pass multiple paramters to a variable in sql developer.
Ex: Select * from Country where state= :statename (Country is table name, state is column name)
If I execute the above query in SQL Developer I can pass only one parameter at a time for :statename ie either KERALA,KARNATAKA,PUNJAB etc.
How can I pass multiple values (all KERALA,KARNATAKA,PUNJAB) or ALL column values at a time in SQL Developer.
Thanks

Array type variables can, as this example using the built in type odcivarchar2list shows
SQL> select
  2      object_name,
  3      object_type
  4  from
  5      all_objects o
  6  where
  7      o.object_name in
  8      (select column_value from
  9      table(sys.odcivarchar2list('DUAL','ALL_OBJECTS')));
OBJECT_NAME                    OBJECT_TYPE
DUAL                           TABLE
DUAL                           SYNONYM
ALL_OBJECTS                    VIEW
ALL_OBJECTS                    SYNONYM
ALL_OBJECTS                    VIEWHere is a full discussion with multiple solutions for various versions including a string parsing

Does SQL Developer support array type variable? I don't know they may know here {forum:id=260}
Otherwise the link above shows how to parse a single character variable into multiple values that will be needed.
