A Name

我试图使用LISTAGG在Oracle查询中添加一个文本字段a.desc。 谁能帮助解决这个语法错误？

我有3个表 1) 表A

id  |  Name      |   Desc     |  
1   |  Name_A_1  |  Desc_A_1  |  
2   |  Name_A_2  |  Desc_A_2  |  
3   |  Name_A_3  |  Desc_A_3  |  

2) 表B

id  |  Name      |   Desc     |  
11  |  Name_B_11 |  Desc_B_11 |  
12  |  Name_B_12 |  Desc_B_12 |  
13  |  Name_B_13 |  Desc_B_13 |  

3) 表C

id  | Table_A_id  | Table_B_id  |  
1   |    1        |     11      |  
2   |    1        |     12      |  
3   |    1        |     13      |  
4   |    3        |     12      |  
5   |    3        |     13      |  

• 以下是当前输出的工作内容

A id | A Name   |  B id(s)   |  
  1  | Name_A_1 | 11; 12; 13 |  
  3  | Name_A_3 | 12; 13     |

Select A.id AS "A id", A.Name AS "A Name",
       LISTAGG(C.id,'; ') WITHIN GROUP (ORDER BY A.id) AS "B id(s)"
From Table_A A
     INNER JOIN Table_C C ON A.id = C.id
     INNER JOIN Table_B B ON B.id = C.id
GROUP BY A.id, A.Name
ORDER BY A.id

• 这里是通过添加 "A Desc "列来实现的第一个期望输出。A id
