定义对象类型:

create or replace type type_row as object

(

id int,

name varchar2(50)

)

修改表对象类型的定义语句如下:

create or replace type type_table is table of type_row;

1)、管道化表函数方式:

create or replace function f_pipe(s number)

return type_table pipelined

as

v_type_row type_row;

begin

for i in 1..s loop

v_type_row := type_row(i,to_char(i*i));

pipe row(v_type_row);

end loop;

return;

end f_pipe;

测试:select * from table(f_pipe(5));

2)、 普通的方式:

create or replace function f_normal(s number)

return type_table

as

rs type_table:= type_table();

begin

for i in 1..s loop

rs.extend;

rs(rs.count) := type_row(rs.count,’name’||to_char(rs.count));

–Result(Result.count) :=
