SqlExceptionHelper-列名..在此结果集中找不到

Question

这是查询：

UPDATE einvoice_message AS e1 
SET message = null 
FROM (
SELECT * 
FROM einvoice_message 
where created < :created 
ORDER BY :created LIMIT :limit 
FOR UPDATE SKIP LOCKED
) AS e2 
WHERE e1.einvoice_message_id = e2.einvoice_message_id 
RETURNING e1.einvoice_message_id

我得了SqlExceptionHelper - The column name created was not found in this ResultSet.不明白为什么在哪里？需要帮助。

Java代码：

@Query(value = "UPDATE einvoice_message AS e1 SET message = null FROM (SELECT * FROM einvoice_message 
where created < :created ORDER BY :created LIMIT :limit FOR UPDATE SKIP LOCKED) AS e2 WHERE 
e1.einvoice_message_id = e2.einvoice_message_id RETURNING e1.einvoice_message_id", nativeQuery = true)
List<EinvoiceMessage> deleteEinvoiceMessageContent(@Param("created") OffsetDateTime created, 
@Param("limit") int limit);

这是我的桌子ddl:

create table einvoice_message
(
einvoice_message_id bigserial not null
constraint einvoice_message_pk
primary key,
message bytea not null,
created timestamp default now() not null
);

将:created变量更改为列created并不能解决问题。

问题出在this的返回值上。RETURNING e1.einvoice_message_id将返回一个数字，而不是我提到的列表。正确的答案是：

@Query(value = "UPDATE einvoice_message AS e1 SET message = null FROM (SELECT * FROM einvoice_message 
where created < :created ORDER BY :created LIMIT :limit FOR UPDATE SKIP LOCKED) AS e2 WHERE 
e1.einvoice_message_id = e2.einvoice_message_id RETURNING e1.einvoice_message_id", nativeQuery = true)
int deleteEinvoiceMessageContent(@Param("created") OffsetDateTime created, 
@Param("limit") int limit);
