如何在日期和时间之间运行查询？

Question

我有一个查询，我需要从两个不同的日期和时间获取信息。
我想拉上昨天和今天之间以及昨天和晚上18:00:00小时的最后修改时间之间修改的所有内容。

我该如何做到这一点？

SELECT A1.CHCASN, 
     A1.CHTRKN, 
     SUM(A2.CDPAKU) AS UNITS, 
     A1.CHACWT, 
     SUM(A2.CDPRC * A2.CDPAKU) AS COST, 
     SUM(A3.STRPRC * A2.CDPAKU) AS RETAIL, 
     A1.CHDLM, 
     A1.CHTLM 
    FROM CHCART00 A1, 
     CDCART00 A2, 
     STSTYL00 A3 
    WHERE A1.CHCASN = A2.CDCASN 
    AND A2.CDSTYL = A3.STSTYL 
    AND A2.CDCOLR = A3.STCOLR 
    AND A2.CDSDIM = A3.STSDIM 
    AND A1.CHSTAT = '25' 
    AND A1.CHROUT = 'UPSCA' 
    AND A1.CHDLM BETWEEN 20110505 And 20110506 
    AND A1.CHTLM >= '160000' 
    AND A1.CHTLM <= '130000' 
GROUP BY A1.CHCASN, A1.CHTRKN, A1.CHACWT, A1.CHDLM, A1.CHTLM 
ORDER BY A1.CHCASN 

Answer 1

也许这样的：

AND (A1.CHDLM = 20110505 
     AND A1.CHTLM >= '160000' 
    OR 
     A1.CHDLM = 20110506 
     AND A1.CHTLM <= '130000' 
    )

更多通用（捕捉的情况下，当这两个日期是不连续的），它应该是：

AND (A1.CHDLM = 20110505 
     AND A1.CHTLM >= '160000' 
    OR 
     A1.CHDLM BETWEEN 20110505 +1 
        AND 20110506 -1 
    OR 
     A1.CHDLM = 20110506 
     AND A1.CHTLM <= '130000' 
    )
