Question

我试图找出具有MS Sql嵌套查询的正确语法，我希望从另一列中获取值，然后将结果转换为绝对值，然后插入到视图中。我该怎么做呢？

     CREATE VIEW -- select * from 
    [Product_Revenue]
      AS
   SELECT Name,[REV_Accounted_Debit]-[REV_Accounted_Credit] as [diff]
   select abs[diff] as Amount from SalesListing
    FROM [SalesListing]

Answer 1

没有必要对此进行递归。

CREATE VIEW -- select * from 
Product_Revenue
  AS
SELECT Name, 
       REV_Accounted_Debit]-[REV_Accounted_Credit as diff,
       abs(REV_Accounted_Debit-REV_Accounted_Credit) as Amount
FROM SalesListing

嵌套查询进入视图？
