Easy SQL Select Case When Statement 抛出不正确的语法错误，我找不到它！

Question

感谢所有试图提供帮助的人！

我有 2 个案例选择语句，但我在此语句中收到错误：

Center,
Case Center
When 'Concord Call Center' Then 'CCC'
When 'Livermore Call Center' Then 'LCC'
When 'Morgan Hill Call Center' Then 'MHCC'
When 'Natomas Call Center' Then 'NCC'
When 'Virtual Call Center' Then 'VCC'
Else Center
End,

我得到的错误是： 没有为“ANDREWSTABLE”的第 14 列指定任何列。

请看下面它在完整声明中的位置：

我哪里做错了？它说我的语法不正确，我盯着又盯着，又用谷歌搜索又用谷歌搜索，但我想不出如何纠正这个问题！它一定很简单。

再次感谢您的帮助！

Answer 1

您只需要列名的别名。因为它是一个派生表，所以它需要它。

 Case Center
    When 'Concord Call Center' Then 'CCC'
    When 'Livermore Call Center' Then 'LCC'
    When 'Morgan Hill Call Center' Then 'MHCC'
    When 'Natomas Call Center' Then 'NCC'
    When 'Virtual Call Center' Then 'VCC'
    Else Center
 End as Center

Answer 2

这部分格式不正确：

    ,Center
Case
When 'Concord Call Center' Then 'CCC'
When 'Livermore Call Center' Then 'LCC'
When 'Morgan Hill Call Center' Then 'MHCC'
When 'Natomas Call Center' Then 'NCC'
When 'Virtual Call Center' Then 'VCC'
Else Center
End
    ,q.Queue AS 'Xferfrom'

Case 之前需要一个逗号，或者Mycenter = 之类的东西，而不是第一个Center。
