Question

当我执行此查询时，我收到错误的'关键字'VIEW'附近的语法错误请帮帮我，这个查询有什么问题？

EXECUTE sp_executesql 
N'
CREATE VIEW LastDayOfMonth
AS
SELECT @MAX = MAX(DATEPART(DAY,CurrencyRateDate))AS CurrencyRateDate FROM Sales.CurrencyRate 
WHERE 
DATEPART(YEAR,CurrencyRateDate)=@YEAR
AND
DATEPART(MONTH,CurrencyRateDate)= @MONTH',
N' @YEAR CHAR(4),@MONTH CHAR(2)',
@YEAR = '2004',
@MONTH = '02';

Answer 1

使用视图或使用sp_executesql，没有明显的理由去做你在这里做的事情。

以下内容应该有效：

DECLARE @MAX INT
DECLARE @YEAR INT
DECLARE @MONTH INT

SET @YEAR = 2004
SET @MONTH = 02

SELECT @MAX = MAX(DATEPART(DAY,CurrencyRateDate))AS CurrencyRateDate FROM Sales.CurrencyRate 
WHERE 
DATEPART(YEAR,CurrencyRateDate)=@YEAR
AND
DATEPART(MONTH,CurrencyRateDate)= @MONTH

并显示结果：

SELECT @MAX

如果这不是你想要做的，也许你可以编辑问题并澄清一下？

Answer 2

我认为问题在于使用未声明的变量@MAX。当你想要返回这个值时，你不需要变量，只需这样做：

EXECUTE sp_executesql 
N'
CREATE VIEW LastDayOfMonth
AS
SELECT 
   MAX(DATEPART(DAY,CurrencyRateDate))AS CurrencyRateDate AS Maximum
FROM Sales.CurrencyRate 
WHERE 
DATEPART(YEAR,CurrencyRateDate)=@YEAR
AND
DATEPART(MONTH,CurrencyRateDate)= @MONTH',
N' @YEAR CHAR(4),@MONTH CHAR(2)',
@YEAR = '2004',
@MONTH = '02';

Answer 3

你可以尝试一下吗？：

EXECUTE DATABASENAME..sp_executesql 
N'
CREATE VIEW LastDayOfMonth
AS
SELECT @MAX = MAX(DATEPART(DAY,CurrencyRateDate))AS CurrencyRateDate FROM Sales.CurrencyRate 
WHERE 
DATEPART(YEAR,CurrencyRateDate)=@YEAR
AND
DATEPART(MONTH,CurrencyRateDate)= @MONTH',
N' @YEAR CHAR(4),@MONTH CHAR(2)',
@YEAR = '2004',
@MONTH = '02';

如果您仍然遇到问题，那么可能是因为您无法使用parameters工作views ..

Answer 4

我有类似的问题。看来你不能在视图中使用参数。而是处理SQL以包含参数：

set @sql = N'create view as select * from table where year = ' + cast(@year as varchar(4));
EXECUTE sp_executesql @sql;

EXECUTE sp_executesql中的错误
