計算並顯示SQL中的數據次數

Question

我有一個像表這樣的表，計數並顯示多少次數據

SQL> select * from COUNT_TEST;

NAME                 ID
-------------------- ---------
A                    4
B                    3
C                    2
D                    1

我想要這樣的輸出：

name     id
A        4
A        4
A        4
A        4
B        3
B        3
B        3
C        2
C        2
D        1

提前致謝。

Answer 1

with COUNT_TEST(NAME, ID) as(
 select 'A',4 from DUAL union all
 select 'B',3 from DUAL union all
 select 'C',2 from DUAL union all
 select 'D',1 from DUAL
)
  select NAME, ID
    from COUNT_TEST
 connect by NAME=prior NAME and level<=ID
     and prior DBMS_RANDOM.value is not null;

這是一個Rextester 。
