Question

我有一个表格，我必须检查列'Type'是否包含数据值为'V'，然后我必须将其作为'F'插入，否则无需更改

我正在使用以下内容并将错误视为不正确的语法。

INSERT INTO [dbo].[Table]
           ([A] ,[B],
           [C],[D] , CASE [Type] WHEN 'F'THEN 'V' else [Type] as Service type,[E]) select   ([A] ,[B],
           [C],[D] ,[Type],[E]   from   [dbo].[Table2]

Answer 1

您的插入语句错误更正，如case表达式

INSERT INTO [dbo].[Table] ([A], [B], [C], [D], [Type], [E]) 
SELECT [A], [B], [C], [D],
       CASE [Type] WHEN 'V'THEN 'F' else [Type] end [Type],[E]
FROM [dbo].[Table2];

Answer 2

insert [dbo].[Table] (a, type)
    select a, CASE [Type] WHEN 'F'THEN 'V' else [Type]
    from dbo].[Table2]

使用案例条件插入表格
