Oracle Table Function在Oracle9i时引入，完美的兼容了view和存储过程的优点：
应用举例：
1.Table()函数:
set feedback offcreate or replace type type_int_date_varchar2 as object (i integer, d date, v varchar2(99))/create or replace type table_int_date_varchar2 as table of type_int_doracle账号ate_varchar2/create or replace function f_int_date_varchar2 return table_int_date_varchar2 as a_type_int_date_varchar2 table_int_date_varchar2 := table_int_date_varchar2();begin a_type_int_date_varchar2.extend; a_type_int_date_varchar2(a_type_int_date_varchar2.count) := type_int_date_varchar2(1,to_date('08.01.1947','dd.mm.yyyy'), 'David Bowie'); a_type_int_date_varchar2.extend; a_type_int_date_varchar2(a_type_int_date_varchar2.count) := type_int_date_varchar2(2,to_date('27.01.1756','dd.mm.yyyy'), 'Mozart'); return a_type_int_date_varchar2;end;/select * from table (cast (f_int_date_varchar2() as table_int_date_varchar2));drop function f_int_date_varchar2;drop type table_int_date_varchar2;drop type type_int_date_varchar2;
2.A Function that returns a table of dates in a Range
create or replace type date_obj as object (dt date)/create or replace type date_table as table of date_obj/create or replace function date_range(from_dt in date, to_dt in date) return date_table as a_date_table date_table := date_table(); cur_dt date:=from_dt; begin while cur_dt <= to_dt loop a_date_table.extend; a_date_table(a_date_table.count) := date_obj(cur_dt); cur_dt := cur_dt + 1; end loop; return a_date_table;end date_range;/
select * from table (cast ( date_range( to_date('01.01.2002','dd.mm.yyyy'), to_date('31.01.2002','dd.mm.yyyy') ) as date_table));
