SQL - 獲取一列比某個列大一定百分比的行

Question

我需要得到一列，其中一列比另一列高一定百分比。

所以說我有2列：

• InventoryLevel int
• InventoryAlert int

我需要獲得InventoryLevel比InventoryAlert大25％的所有行。

這可以在一個查詢中完成所有操作嗎？ 任何幫助將不勝感激！

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 >= ?
