sql - 有没有其他方法可以缩短这个 SQL 函数，尤其是 MOD 函数？

Question

我有这个查询

SELECT Calendar."Production Week" FROM Opex 
WHERE 
(
Calendar."Production Week" BETWEEN  VALUEOF("LAST_WEEK")-200 
AND  
VALUEOF("LAST_WEEK")
) 
OR 
(
(
(MOD(Calendar."Production Week", 100) = 1) 
OR 
(MOD(Calendar."Production Week", 100) = 13) 
OR 
(MOD(Calendar."Production Week", 100) = 26) 
OR 
(MOD(Calendar."Production Week", 100) = 39) 
OR 
(MOD(Calendar."Production Week", 100) = 52)   
)  
AND 
(Calendar."Production Week" <=
VALUEOF("LAST_WEEK"))
) 
ORDER BY Calendar."Production Week" DESC

那么我的问题是，是否有任何其他方法可以使此查询比它更短，尤其是 MOD 函数，因为它具有相同的结果 200639、200652、200713、2007 26、200739 等？提前致谢。

Answer 1

MOD(Calendar."Production Week", 100) IN (1,13,26,39,52) 

够了吗？

Answer 2

您可以将 OR 链更改为 IN 子句

MOD(Calendar."Production Week", 100) in (1,13,26,39,52)

Answer 3

SELECT Calendar."Production Week" FROM Opex
WHERE (
     Calendar."Production Week" BETWEEN VALUEOF("LAST_WEEK")-200 AND VALUEOF("LAST_WEEK")
)
OR
(
     (
        (MOD(Calendar."Production Week", 100) in (1, 13, 26, 39, 52)
     )
     AND  (Calendar."Production Week" <= VALUEOF("LAST_WEEK"))
)
ORDER BY Calendar."Production Week" DESC
