LISTAGG在Oracle Cloud中不起作用

Question

我正在尝试运行下面的查询

select organization_id
  , listagg(secondary_inventory_name, ',') within group(order by secondary_inventory_name) as the_list
from inv_secondary_inventories
group by organization_id

，但它一直给出这个错误：

oracle.xdo.servlet.data.DataException: oracle.xdo.XDOException: java.sql.SQLSyntaxErrorException: ORA-00923: FROM keyword not found where expected

我做错了什么？

Answer 1

select organization_id
  , listagg(secondary_inventory_name, ',') within group(order by secondary_inventory_name) as the_list
from inv_secondary_inventories
group by organization_id

以上是您的查询。只需将listagg语句放在方括号中，这将起到神奇的作用。

select organization_id
  ,( listagg(secondary_inventory_name, ',') within group(order by secondary_inventory_name) )as the_list
from inv_secondary_inventories
group by organization_id
