java - Postgres : syntax error at or near "as"

Question

我正在使用 JOOQ for java 到 postgresql 数据库连接。它正在尝试运行此查询。

insert into "public"."mission_batches" as "MB" 
  ("micro_task_id", "is_active", "created_at", "updated_at") 
values 
  ('7e1cc9e8-fc11-409b-865e-3bf08e6ca924', false, timestamp '2016-10-05 21:47:13.061', timestamp '2016-10-05 21:47:13.061') returning "MB"."id", "MB"."micro_task_id", "MB"."is_active", "MB"."created_at", "MB"."updated_at"

但是我从数据库收到错误

org.jooq.exception.DataAccessException: SQL [insert into "public"."mission_batches" as "MB" ("micro_task_id", "is_active", "created_at", "updated_at") values (?, ?, cast(? as timestamp), cast(? as timestamp)) returning "MB"."id", "MB"."micro_task_id", "MB"."is_active", "MB"."created_at", "MB"."updated_at"];
ERROR: syntax error at or near "as"
  Position: 40

它正在与我的本地数据库[9.5]一起使用。在测试服务器 [9.4] 上，它抛出此错误。我应该去哪里寻找修复？ Java端还是PG端？

为要插入的表设置别名仅在 Postgres 9.5 中添加(将 Postgres 9.5's documentation 与 9.4's documentation 进行比较。由于 returning 子句中的列无论如何都引用插入的表，因此您可以没有它也同样容易:

insert into "public"."mission_batches"
  ("micro_task_id", "is_active", "created_at", "updated_at") 
values 
  ('7e1cc9e8-fc11-409b-865e-3bf08e6ca924', false,
   timestamp '2016-10-05 21:47:13.061', timestamp '2016-10-05 21:47:13.061') 
returning 
  "id", "micro_task_id", "is_active", "created_at", "updated_at"
