Question

我正在为@StartFixtureDay检索必须声明的标量变量错误，但不确定我需要做什么或看到我的代码出现问题：

CREATE PROCEDURE [dbo].[Date_Insert]

AS
SET NOCOUNT ON
BEGIN

DECLARE @StartFixtureDay DATE
SET @StartFixtureDay = CAST(GETDATE() AS DATE)

    ;WITH League_Dates AS (
...
 SELECT rn,
           week_number,
           DATEADD(day, week_number - 1, @StartFixtureDay) AS WeekNumber,
...

...下面的执行官是在一个单独的页面上

EXEC [dbo].[Date_Insert] @StartFixtureDay

Answer 1

您必须将@StartFixtureDay声明为存储过程

的参数

CREATE PROCEDURE [dbo].[Date_Insert] (@StartFixtureDay date)
AS
...

Answer 2

该过程未被定义为具有参数但您正在传递过程。

您需要先将参数放入过程定义中，然后才能传递它

Answer 3

您已在存储过程中声明@StartFixtureDay。当您致电EXEC时，您的手术超出了您的范围。而这个OUTside代码确实不知道INside变量。在EXEC之前声明您的变量并在您的过程中声明参数

CREATE PROCEDURE [dbo].[Date_Insert] (@ParamName DATE)
AS
    DECLARE @StartFixtureDay DATE
    SET @StartFixtureDay = @ParamName
...

...

DECLARE @OutsideVriable DATE
SET @OutsideVriable = CAST(GETDATE() AS DATE)
EXEC [dbo].[Date_Insert] @OutsideVariable

Answer 4

如上所述，根据您的执行程序提出建议，您的datatime参数需要定义。

你也写错了，请更正

CREATE PROCEDURE [dbo].[Date_Insert]

AS
SET NOCOUNT ON
BEGIN

DECLARE @StartFixtureDay DATE
SET @StartFixtureDay = ( Select CAST(GETDATE() AS DATE))  --direct cast not work, need to select keyword

GETDATE标量变量
