hsqldb 中的间隔格式异常无效，但查询在 Postgres 中有效

Question

我正在 postgresql 中运行查询。它在 psql 中运行良好，但出于单元测试的目的，我创建了一个内存 HSQLDB 并在其中执行了相同的查询。但是会抛出“Invalid interval format”异常。由于我是 hsqldb 新手，所以我无法找出问题的根本原因。

查询：

INSERT INTO microbatch_redrive
SELECT mii.*,(to_char(CURRENT_TIMESTAMP ,'yyyy-mm-ddThh:mi:ss.msZ')) FROM
(SELECT * FROM
  ( SELECT mi.*,me.extractid FROM
    (SELECT * FROM microbatch_info WHERE
        ((numattempts<= ${maxNumOfAttempts})
        AND (starttime>= '${starttime}') 
        AND (starttime<= '${endtime}')))
    AS mi LEFT OUTER JOIN microbatch_extract_info AS me ON mi.microbatchid = me.microbatchid) 
    AS mime WHERE((mime.raverunstatus='SUCCEEDED' AND mime.extractid is null)
    OR (mime.starttime < to_char(CURRENT_TIMESTAMP,'yyyy-mm-ddThh:mi:ss.msZ') AND mime.raverunstatus='NOT_STARTED')
    OR (mime.raverunstatus = 'FAILED')
    OR (mime.raverunstatus='STARTED' AND mime.starttime< (to_char(CURRENT_TIMESTAMP - INTERVAL '1 hour' * ${extractTimeIntervalInHour},'yyyy-mm-ddThh:mi:ss.msZ')))
    )
) AS mii LEFT OUTER JOIN
(SELECT microbatchid FROM microbatch_redrive WHERE raverunstatus='REDRIVE_SUCCEEDED') AS mr ON mii.microbatchid=mr.microbatchid WHERE mr.microbatchid IS NULL;

错误：

INTERVAL '1 hour' 是 Postgres 特定的区间语法。

在标准 SQL 中，您需要：INTERVAL '1' hour，它也受 HSQLDB 支持（如果您需要适用于这两种产品的语句，则还支持 Postgres）。

所以完整的表达式应该是：

CURRENT_TIMESTAMP - INTERVAL '1' hour * ${extractTimeIntervalInHour}
