Question

我在Sql Server中编写了这样的程序：

CREATE PROCEDURE p_SelectDatesFromRange
(
    @startDate DATETIME,
    @endDate DATETIME
)
AS
(
    ;WITH dates AS
    (
        SELECT @startDate AS [Date]
        UNION ALL
        SELECT DATEADD(day, 1, [Date])
        FROM dates
        WHERE [Date] <= @endDate - 1
    )
    SELECT *
    FROM dates
);

它应返回两个给定参数之间的所有日期。但是我无法运行它，它给了我一个错误。

Incorrect syntax near ';'
Incorrect syntax near ')'

此错误位于“with”的开头，位于程序代码的末尾。

我正在学习CTE，很抱歉，如果这是明显的错误。

请帮助，谢谢，迈克。

Answer 1

我不确定您的错误与CTE本身有什么关系，而是您尝试使用括号来表示存储过程的主体。要么删除括号，要么使用BEGIN和END块：

CREATE PROCEDURE p_SelectDatesFromRange
(
    @startDate DATETIME,
    @endDate DATETIME
)
AS

BEGIN

    ;WITH dates AS
    (
        SELECT @startDate AS [Date]
        UNION ALL
        SELECT DATEADD(day, 1, [Date])
        FROM dates
        WHERE [Date] <= @endDate - 1
    )

    SELECT *
    FROM dates
END;

Answer 2

这有效

CREATE PROCEDURE DBO.DateRange  
    @start datetime,   
    @end datetime  
AS  
    with cte as 
    ( SELECT @start as strtDt, @end as endDt
      union all 
      select strtDt + 1, endDt 
      from cte 
      where strtDt < endDt
    )
select * from cte

CTE，';'附近的语法不正确SQL SERVER
