SQL 创建视图，显示视图，关键字“SELECT”附近的语法不正确

Question

sql问题，我创建了一个视图，但是问题来自于什么时候 我尝试使用从视图中选择 * 来显示视图。

CREATE VIEW YearByYearSalesDelta as 
WITH temp 
    as (select SalesPersonID,YEAR(DueDate) as SaleYear, SUM(SubTotal) as Total 
        from Sales.SalesOrderHeader
        group by SalesPersonID, year(DueDate)
        )
    select NewYear.SalesPersonID,
        OldYear.SaleYear AS OldYear, 
        NewYear.SaleYear as NewYear,
        NewYear.Total-OldYear.Total as Delta
    from temp AS OldYear 
        JOIN temp AS NewYear  on   NewYear.SalesPersonID=OldYear.SalesPersonID
                AND NewYear.SaleYear-1=OldYear.SaleYear

SELECT * FROM dbo.YearByYearSalesDelta

消息显示

**Msg 156, Level 15, State 1, Procedure YearYearSalesDelta, Line 15
Incorrect syntax near the keyword 'SELECT'.**

Answer 1

你应该在视图之后使用批处理分隔符 GO

CREATE VIEW YearByYearSalesDelta as 
WITH temp 
    as (select SalesPersonID,YEAR(DueDate) as SaleYear, SUM(SubTotal) as Total 
        from Sales.SalesOrderHeader
        group by SalesPersonID, year(DueDate)
        )
    select NewYear.SalesPersonID,
        OldYear.SaleYear AS OldYear, 
        NewYear.SaleYear as NewYear,
        NewYear.Total-OldYear.Total as Delta
    from temp AS OldYear 
        JOIN temp AS NewYear  on   NewYear.SalesPersonID=OldYear.SalesPersonID
                AND NewYear.SaleYear-1=OldYear.SaleYear

GO

SELECT * FROM dbo.YearByYearSalesDelta
