SQL - 获取一列比某个列大一定百分比的行

Question

我需要获取一列比某个列大一定百分比的行。

所以说我有两列：

• InventoryLevel int
• InventoryAlert int

我需要获取InventoryLevel比InventoryAlert大25％的所有行。

这可以在一个查询中完成所有操作吗？任何帮助将不胜感激！

Answer 1

SELECT InventoryLevel,
       InventoryAlert  
FROM YourTable
WHERE InventoryLevel > 1.25 * InventoryAlert 
/*Incorrect for stated question but meets clarification in comment 
  "InventoryLevel is any value greater than 25%, doesn't have to be exact. "*/

Answer 2

SELECT *
FROM YourTable
WHERE InventoryLevel = 1.25*InventoryAlert -- Or Maybe >= ?
