重写 OUTER APPLY to Join 或除申请测试 Blazing SQL（基于 GPU）以外的任何内容

Question

除了我的加速查询外，还要感谢 a_horse_with_no_name 将我的函数重写为外部应用，这使我的查询运行已经快了 10 倍。但是，速度还是不够快，不能做我想做的事情。

现在，我正在尝试使用 GPU 来进一步加速，方法是使用 blazing SQL。不幸的是，它 returns “在当前 SQL 一致性级别下不允许使用 APPLY 运算符” ... 任何人都知道如何重写以下代码以加入或除应用之外的任何其他代码，所以我可以给出一个试炼到炽热SQL？我会 post 试用后的速度差异。

SELECT IIF (TargetTime.MinTime <= CLTime.MinTime , [Target] ,[CL])  
FROM [defaultDB].[dbo].[Table1] AS M
JOIN(VALUES(0.003), (0.0035), (0.004), (0.0045), (0.005), (0.0055), (0.006), (0.0065), (0.007), (0.0075), (0.008)) AS T([target])
    ON 1 = 1
JOIN(VALUES(-0.003), (-0.0035), (-0.004), (-0.0045), (-0.005), (-0.0055), (-0.006), (-0.0065), (-0.007), (-0.0075), (-0.008), (-0.0085), (-0.009), (-0.0095), (-0.01), (-0.0105), (-0.011), (-0.0115)) AS C([CL])
    ON 1 = 1
OUTER APPLY
            (
             SELECT MIN([time]) AS MinTime
             FROM [defaultDB].[dbo].[Table2]
             WHERE [date] = M.[DATE]
                   AND [Start] >= M.Stime
                   AND [Time] <= M.etime
                   AND [H] > T.target
            ) as TargetTime
OUTER APPLY
            (
             SELECT MIN([time]) AS MinTime
             FROM [defaultDB].[dbo].[Table2]
             WHERE [date] = M.[DATE]
                   AND [Start] >= M.Stime
                   AND [Time] <= M.etime
                   AND L < C.CL
            ) as CLTime
WHERE [M].[date] IN(20120307, 20120601, 20121109, 20130826, 20131002, 20140117, 20140122, 20140311, 20140529, 20140718, 20150619, 20151014, 20151022, 20160411, 20160516, 20160721, 20160818, 20160909, 20170127, 20170213, 20170921, 20171025, 20171229, 20180116, 20180315, 20180926, 20181022, 20181128, 20181211, 20190104, 20190329, 20190502, 20190521, 20190528, 20190611, 20190627, 20190823, 20190930, 20191104, 20191211, 20200214, 20200318, 20200529, 20200706, 20200828, 20201230, 20210112, 20210305, 20210318, 20210408, 20210525, 20210617, 20210625)
  AND [Stime] >= 133000;

有一个参数可以禁用此类连接.... 将 allow-loop-joins 设置为 true 然后你可以做所有 reference
