假设我有一个下面给出的范围

400001 - 400104
400601 - 400614
400701 - 400710
401101
401104
401105
401107
401201
401202
401203
401207
401209
401301
401303
421001 - 421005
421201
421202
421203
421204
421301
421304
421306

而且我必须在下面给定的范围内找到数据，而不是告诉我最简单的方法。我在函数中使用并解决它，但如果有更多的范围会变得更加乏味

除了乏味之外，in还有 1000 个值的限制，如果您的范围很大，您可能会达到这个值。

如果您可以将 Excel 数据转换为可以生成文本以形成 CTE 的格式，您可能可以使用公式执行此操作，您可以执行以下操作：

with tmp_tab as (
    select 400001 as range_from, 400104 as range_to from dual
    union all select 400601, 400614 from dual
    union all select 400701, 400710 from dual
    union all select 401101, null from dual
    union all select 401104, null from dual
    union all select 401105, null from dual
    union all select 401107, null from dual
    union all select 401201, null from dual
    union all select 401202, null from dual
    union all select 401203, null from dual
    union all select 401207, null from dual
    union all select 401209, null from dual
    union all select 401301, null from dual
    union all select 401303, null from dual
    union all select 421001, 421005 from dual
    union all select 421201, null from dual
    union all select 421202, null from dual
    union all select 421203, null from dual
    union all select 421204, null from dual
    union all select 421301, null from dual
    union all select 421304, null from dual
    union all select 421306, null from dual
)
select st.id, st.data
from some_table st
join tmp_tab tt on st.id between tt.range_from
    and nvl(tt.range_to, tt.range_from);

因此，您可以根据 Excel 数据构建一个公用表表达式，其中包含 range-from 和 range-to；如果您只有一个数字，则可以将 range-to 保留为 null 并nvl稍后使用以使其成为虚拟范围；然后在您的表中查找任何范围内的数据。

棘手的一点是生成 CTE，但即使从您拥有的数据手动执行此操作也比手动将每个范围扩展到所有单独的值更容易。

我认为使用 IN 是不可能的，但您可以将数据插入到临时表或表变量中：

DECLARE @table TABLE (value int)
INSERT INTO @table VALUES (400001),(400002),(400003),(400004),(400005),(400006),(400007),(400008),(400009),(400010),(400011),(400012),(400013),(400014),(400015),(400016),(400017),(400018),(400019),(400020),(400021),(400022),(400023),(400024),(400025),(400026),(400027),(400028),(400029),(400030),(400031),(400032),(400033),(400034),(400035),(400036),(400037),(400038),(400039),(400040),(400041),(400042),(400043),(400044),(400045),(400046),(400047),(400048),(400049),(400050),(400051),(400052),(400053),(400054),(400055),(400056),(400057),(400058),(400059),(400060),(400061),(400062),(400063),(400064),(400065),(400066),(400067),(400068),(400069),(400070),(400071),(400072),(400073),(400074),(400075),(400076),(400077),(400078),(400079),(400080),(00081),(400082),(400083),(400084),(400085),(400086),(400087),(400088),(400089),(400090),(400091),(400092),(400093),(400094),(400095),(400096),(400097),(400098),(400099),(400100),(400101),(400102),(400103),(400104),(400601),(400602),(400603),(400604),(400605),(400606),(400607),(400608),(400609),(400610),(400611),(400612),(400613),(400614),(400701),(400702),(400703),(400704),(400705),(400706),(400707),(400708),(400709),(400710),(401101),(401104),(401105),(401107),(401201),(401202),(401203),(401207),(401209),(401301),(401303),(421001),(421002),(421003),(421004),(421005),(421201),(421202),(421203),(421204),(421301),(421304),(421306)

DECLARE @minValue INT
SET @minValue = (SELECT MIN (value) FROM @table)

DECLARE @valueToTest INT
SET @valueToTest = 200

PRINT CASE WHEN @valueToTest < @minValue THEN 'below range'
           ELSE 'NOT below range'
      END
