我创建了这个函数，它接受三个参数。我有几个关于执行此功能的问题。

从字符串转换日期和/或时间时转换失败

这是我尝试以下列方式执行此功能时收到的错误

select * from [dbo].[fn_InventoryPositionSet] (GETDATE(), 1, null)

即使我通过2012-03-10而不是getdate()

我也想学习如何以列表的形式传递参数。作为参数之一是列表的形式。如果您想了解有关该功能的更多信息，请告诉我。

这是在上面编写的函数中使用的函数：

CREATE FUNCTION [dbo].[COBTimestamp]
(
    @COBDate DATETIME
)
RETURNS DATETIME
AS
BEGIN

    RETURN DATEADD(day, DATEDIFF(day, 0, @COBDate), '23:59:59')             

END
GO

查看您的表定义：

1. Account            VARCHAR(10),
2. PositionId         VARCHAR(150),
*** 3. VersionDate        DATETIME, ***
4. ProductType        VARCHAR(50),
5. XRef               VARCHAR(50),
6. XRefType           VARCHAR(20),
7. Desk               VARCHAR(50)

你的选择：

            SELECT      
                1. P.Account,
                2. P.UniquePositionId AS [PositionId],
                *** 3. P.Desk, ***
                4. P.VersionEffective AS [VersionDate],
                5. P.ProductType,
                6. P.XRef,
                7. P.XRefType

不在其中的问题[dbo].[fn_InventoryPositionSet]在[dbo].[COBTimestamp].

RETURN DATEADD(day, DATEDIFF(day, 0, @COBDate), '23:59:59')
                                                    ^__________ Must be converted to `DATETIME`

日期添加 (Transact-SQL)
