SQL Server切換數據以顯示其他內容

Question

我試圖弄清楚我可以隨時更改數據。

這是我當前的查詢：

SELECT [EmployeeTC_No] AS "Employee TC#"
      ,[pye_nlast] AS "Name Last"
      ,[pye_nfirst] AS "Name First"
      ,[Dept] AS "Department"
      ,[pye_status] AS "Active"
      ,[HireDate] AS "Hire Date"
      ,[SeparationDate] AS "Separation Date"
  FROM [testing].[dbo].[testing]

在pye_status列中，數據以“ A”或“ T”形式輸入，我希望它是“ 1”或“ 0”。

我嘗試添加一個case語句以嘗試進行某種切換，但似乎什么也沒有使我接近。

Answer 1

CASE /何時應該做到這一點：

,CASE WHEN [pye_status] = 'A' THEN 1 
WHEN [pye_status] = 'T' THEN 0 
ELSE NULL END AS "Active"

或一個簡單的案例/何時也可以工作：

, CASE [pye_status]
WHEN 'A' THEN 1 
WHEN 'T' THEN 0
ELSE NULL END AS "Active"

Answer 2

使用CASE表達式或IIF()函數作為

CASE WHEN [pye_status] = 'A' THEN 1 ELSE 0 END AS [Active]

要么

IIF([pye_status] = 'A', 1, 0) AS [Active]
