Question

我试图弄清楚我可以随时更改数据。

这是我当前的查询：

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，数据以“ A”或“ T”形式输入，我希望它是“ 1”或“ 0”。

我试图添加一个case语句以尝试进行某种切换，但似乎什么也没有使我关闭。

Answer 1

案例/何时应该完成：

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

或者一个简单的案例/什么时候也可以工作：

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

Answer 2

使用 CASE 表达式或 IIF() 函数作为

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

OR

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

SQL Server切换数据以显示其他内容
