我需要将@sampleTrans中idno的记录与@sampleReceipt中最近的日期（标尺）相匹配。我有查询，但它给了我不同的结果。很感谢任何形式的帮助。请参见下面的示例DDL和预期结果。谢谢。

DEclare @sampleReceipt table
(
csno varchar(50), idno varchar(50), rdt datetime, descript varchar(35))

insert @sampleReceipt values ('ABCDE5B12AG123383814.0611','ABCDE5B12AG12338','2018-04-18 07:34:34.000','receive')
insert @sampleReceipt values ('ABCDE5B12AG123383064.3556','ABCDE5B12AG12338','2018-01-02 10:59:11.000','receive')

尝试这个

select t1.id, t1.idno, t1.recover, t1.dt, t1.roid, t1.opdesc, t1.lineid ,
csno=(select top 1 csno from @sampleReceipt t2 order by ABS(DATEDIFF(second,t1.dt,t2.rdt))),
rdt=(select top 1 rdt from @sampleReceipt t2 order by ABS(DATEDIFF(second,t1.dt,t2.rdt)))
from @sampleTrans t1
order by t1.idno, t1.dt

到目前为止，该代码是否可以正常工作，但我担心如果我有数百万条记录还是可以简化此代码，是否可以使用？ 

  SELECT r.*, p.id, p.idno as idnum, p.recover , p.dt, p.lineid, p.opdesc,
     DENSE_RANK() OVER(PARTITION BY r.idno,rdt ORDER BY roid DESC) 
     AS Seq
     FROM (SELECT *,LEAD(rdt,1,'20491231') OVER (PARTITION BY idno 
    ORDER BY rdt) AS NxtDate
    FROM @sampleReceipt) r
    JOIN @sampleTrans p
    ON p.idno = r.idno
   AND p.dt BETWEEN r.rdt AND NxtDate

尝试执行此查询，它使用CROSS JOIN从两个表中获取所有可能的行组合，然后获取日期之间差异最小的行（使用ROW_NUMBER函数）：

select * from (
    select st.*,
           sr.csno,
           row_number() over (partition by st.id, st.dt order by abs(datediff(minute, st.dt, sr.rdt)) desc) rn
    from @sampleTrans st
    cross join @sampleReceipt sr
) a where rn = 1
