子查询中是否支持esper having子句？

Question

我在esper中编写以下查询：

on pattern[every timer:interval(10 sec)] delete from OrderEvent as OE where OE.orderId IN (select orderId from OrderEvent group by orderId having last(orderAction) = CANCEL)

但它给我一个语法错误，如果不支持那么可以替代解决方案

Answer 1

根据文档，它看起来像＆＃34;有＆＃34;子查询中不支持子句。另一种方法是选择并导致删除。

on pattern[..] insert into DELETED_ID select orderId from OrderEvent where orderAction=CANCEL
on DELETED_ID as del delete from OrderEvent as orderEvent where orderEvent.orderId = del.orderId
