SQL - 获取一列比某个列大一定百分比的行

Question

I need to get rows where one column is a certain percentage greater than another.

So say I have 2 columns:

• InventoryLevel int
• InventoryAlert int

I need to get all rows where the InventoryLevel is 25% greater than the InventoryAlert .

Is that possible to do all in one query? Any help would be greatly appreciated!

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 >= ?
