Question

这是我下面的代码：

SELECT 
    DV.ERSDataValues_ERSCommodity_ID AS Commodity_ID,

WHERE (CVO.ERSConstructedVariable_DataRowPrivacyID = 1)

我想添加行号功能，以便为每行获取唯一的ID，我在此链接中尝试过这种方式 Row_Number() with union query 但这没有用，对如何执行此操作有任何想法吗？

我建议您不要使用[source]或[date]作为列别名，并且在where子句中，您不需要用括号将每个谓词括起来。

我无法验证的是，所有列数据类型都是兼容的，但查询应如下所示：

SELECT
    commodity_id
  , sector
  , group_description
  , commodityname
  , statistic_type
  , [source]
  , physical_attribute
  , util_practice
  , production_practice
  , time_frequency
  , [date]
  , geography_type
  , geography_dimension
  , unit_description
  , value
  , row_number() over(order by commodity_id) as rn
FROM (
        SELECT
            dv.ERSDataValues_ERSCommodity_ID        AS commodity_id
