Question

我有一个带有字段的表（A，B，C，D，E，F，G，H，I）。

所有这些（A，B，C，D，E，F，G，H，I）字段均为2010-02-24至2020-01-18的日期字段。

现在我想选择2014年和2015年的所有（A，B，C，D，E，F，G，H，I）字段。

Answer 1

您可以使用and添加另一个where子句，然后使用between

检查某个值是否在某个范围内

...
where A between '20140101' and '20153112'
  and B between '20140101' and '20153112'
  and C between '20140101' and '20153112'
  and ...

Answer 2

这不是很干净的代码，但是这会找到并记录任何一个f ... A ...我的值在@DATESTART和@DATEEND

的范围内

DECLARE @T TABLE (A DATE,B DATE, C DATE, D DATE, E DATE , F DATE, G DATE, H DATE, I DATE)
DECLARE @DATESTART DATE = '2010-02-24'
DECLARE @DATEEND DATE = '2020-01-18'

INSERT INTO @T VALUES ('2010-02-24','1986-06-27','1968-09-01','1968-01-15','1968-01-18','1986-06-27','1986-06-27','2010-02-24','1986-06-27'),

SELECT  A,B,C,D,E,F,G,H,I FROM @T
WHERE
    A BETWEEN @DATESTART AND @DATEEND
    OR
    B BETWEEN @DATESTART AND @DATEEND
    OR
    C BETWEEN @DATESTART AND @DATEEND
    OR
    D BETWEEN @DATESTART AND @DATEEND
    OR
    E BETWEEN @DATESTART AND @DATEEND
    OR
    F BETWEEN @DATESTART AND @DATEEND
    OR
    G BETWEEN @DATESTART AND @DATEEND
    OR
    H BETWEEN @DATESTART AND @DATEEND
    OR
    I BETWEEN @DATESTART AND @DATEEND
