sql - Oracle 计数函数

我有一个像这样的 SQL

SELECT A.HESAP_NO, A.TEKLIF_NO1 || '/' || A.TEKLIF_NO2 AS TEKLIF
MV_K(A.TEKLIF_NO1,A.TEKLIF_NO2, A.DATE) AS KV
FROM S_TEKLIF A

当我想计算 MV_K(A.TEKLIF_NO1,A.TEKLIF_NO2, A.DATE)/COUNT(@TEKLIF) 但它不起作用时。

我使用 Oracle。

我如何在 Oracle 中这样划分?

这是我的完整 aspx 代码;

最佳答案

显然未经测试,但它应该是这样的:

SELECT A.HESAP_NO
, A.TEKLIF_NO1 || '/' || A.TEKLIF_NO2 AS TEKLIF
, MV_K(A.TEKLIF_NO1,A.TEKLIF_NO2, A.DATE) / count(*) over () AS KV
FROM S_TEKLIF A

说明:如果您想使用计数 (*),则必须在查询中进行聚合,但您并没有这样做。因此,您可以使用分析函数 count(*) over (),它为每一行计算相同的数字。

希望这对您有所帮助。

问候,
罗布。
