如何根据特定列更新行的子集

Question

我有以下查询返回基于con CBU和DATE（Fecha）的数据订单集

SELECT 
    cta.CODIGO, cta.cbu, cta.fecha
FROM
    CUENTA_BANCARIA as CTA
WHERE
    (CTA.ESTADO = 1) and (CTA.HABILITADA = 1)
    AND EXISTS (SELECT C.* 
                FROM CUENTA_BANCARIA as C 
                WHERE (C.CODIGO != CTA.CODIGO) 
                  AND (C.NRO_CTA =  CTA.NRO_CTA) 
                  AND (C.CBU = CTA.CBU) 
                  AND (C.ESTADO = 1) 
                  AND (C.HABILITADA = 1))
ORDER BY
    CTA.CBU, CTA.FECHA DESC

我需要使用没有最新DATE（FECHA）的相同CBU更新任何CUENTA_BANCARIA

例如，对于给定的结果，我需要使用以橙色突出显示的codigo更新CUENTA_BANCARIA，因为它们都具有相同的CBU但是较旧的DATE（FECHA）

如何创建此类查询？

关于RowNumber及Partition By @pmbAustin消息，这是解决方案

update cb
set cb.HABILITADA = 0
from CUENTA_BANCARIA cb
where cb.codigo in (
select SubQuery.codigo
(SELECT cta.CODIGO, cta.NRO_CTA, cta.cbu, cta.fecha, ROW_NUMBER() over (PARTITION BY CTA.cbu order by CTA.fecha desc) as numRepetido
from CUENTA_BANCARIA as CTA
where 
(CTA.ESTADO = 1) and (CTA.HABILITADA = 1)
and 
exists (SELECT C.* FROM CUENTA_BANCARIA as C where (C.CODIGO != CTA.CODIGO) and (C.NRO_CTA =  CTA.NRO_CTA) and (C.CBU = CTA.CBU) and (C.ESTADO = 1) and (C.HABILITADA = 1))) as SubQuery
where SubQuery.numRepetido != 1)
