创建函数SQL-Server语法不正确

Question

我是SQL Sg服务器的新手，我正在尝试使用create函数运行代码将USD的价格转换为十进制。我得到以下旗帜

“语法不正确：'创建函数'必须是批处理中唯一的语句。

谁能指出我做错了什么？谢谢！

CREATE FUNCTION week3.ConvertToEuro ( @priceUSD decimal(5,2))
returns decimal (5,2)

begin
        declare @PriceEuro decimal (5,2)
        set @PriceEuro =(@priceUSD * .89)
        return @PriceEuro

        end 

SELECT TOP (1000) [ProductName]
      ,[price]
      ,week3.ConvertToEuro(price) as PriceEuro
  FROM [AA5100_edmistonml].[Week3].[productprice]

Answer 1

两个语句都不同，你要么单独运行，要么放GO：

CREATE FUNCTION week3.ConvertToEuro ( @priceUSD decimal(5,2))
returns decimal (5,2)
begin
        declare @PriceEuro decimal (5,2)
        set @PriceEuro =(@priceUSD * .89)
        return @PriceEuro
end 

GO

SELECT TOP (1000) [ProductName], [price], week3.ConvertToEuro(price) as PriceEuro
FROM [AA5100_edmistonml].[Week3].[productprice];

Answer 2

尝试如下

CREATE FUNCTION week3.ConvertToEuro ( @priceUSD decimal(5,2))
returns decimal (5,2)
as -- add this 
begin
        declare @PriceEuro decimal (5,2)
        set @PriceEuro =(@priceUSD * .89)
        return @PriceEuro

        end 

go -- add this
SELECT TOP (1000) [ProductName]
      ,[price]
      ,week3.ConvertToEuro(price) as PriceEuro
  FROM [AA5100_edmistonml].[Week3].[productprice]

Answer 3

尝试创建as语句并在语句之间添加go

CREATE FUNCTION week3.ConvertToEuro ( @priceUSD decimal(5,2))
returns decimal (5,2)
as  
begin
        declare @PriceEuro decimal (5,2)
        set @PriceEuro =(@priceUSD * .89)
        return @PriceEuro

        end 

go  
SELECT TOP (1000) [ProductName]
      ,[price]
      ,week3.ConvertToEuro(price) as PriceEuro
  FROM [AA5100_edmistonml].[Week3].[productprice]
