根据你提供的存储过程代码，我发现问题可能在于将 aDatetime 列转换为了 UPLOAD_TIME。

你可以尝试修改存储过程的代码，使用 CONVERT 函数将 aDatetime 列转换为 datetime 类型，然后将其插入到 B_DAM_WATER_LEVEL 表中。具体代码如下：

CREATE PROCEDURE kushuiwei
AS
BEGIN
    INSERT INTO [tewp].[dbo].[B_DAM_WATER_LEVEL](DAM_ID, SENSOR_ID, WATER_LEVEL, UPLOAD_TIME)
    SELECT 27 as DAM_ID, 65 AS SENSOR_ID, CONVERT(datetime, aDatetime) as UPLOAD_TIME, X as WATER_LEVEL
    FROM [Proj].[dbo].[库水位]
    WHERE aDatetime >= DATEADD(MINUTE, -10, GETDATE())
END

这样应该就能解决你遇到的问题了。如果还有其他问题，请随时问我。

USE [lichangtong] GO /****** Object: Table [dbo].[SC] Script Date: 06/07/2023 15:32:52 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[SC]( [Sno] [char](9) NOT NULL, [Cno] [char](4) NOT NULL, [Grade] [smallint] NULL, PRIMARY KEY CLUSTERED ( [Sno] ASC, [Cno] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO SET ANSI_PADDING OFF GO ALTER TABLE [dbo].[SC] WITH CHECK ADD FOREIGN KEY([Cno]) REFERENCES [dbo].[Course] ([Cno]) GO ALTER TABLE [dbo].[SC] WITH CHECK ADD FOREIGN KEY([Sno]) REFERENCES [dbo].[Student] ([Sno]) GO

这是一个 SQL Server 数据库中的一段代码，用于创建一个名为 SC 的表。该表包含三个列：Sno、Cno 和 Grade。其中Sno和Cno均为字符类型，且都是非空的。Grade列是一个小整数类型，可以为空。表的主键是Sno和Cno的组合。此外，该表还定义了两个外键，分别引用了Course表和Student表中的Cno和Sno列。这样可以确保在插入或更新SC表中的数据时，对应的学生和课程的信息必须存在于Student和Course表中。

GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[GGUser]( [UserID] [varchar](50) NOT NULL, [PasswordMD5] [varchar](100) NOT NULL, [Phone] [varchar](20) NOT NULL, [Name] [nvarchar](50) NOT NULL, [Friends] [nvarchar](4000) NOT NULL, [CommentNames] [nvarchar](max) NOT NULL, [OrgID] [nvarchar](20) NOT NULL, [Signature] [nvarchar](100) NOT NULL, [HeadImageIndex] [int] NOT NULL, [HeadImageData] [image] NULL, [Groups] [varchar](1000) NOT NULL, [UserState] [int] NOT NULL, [PcOfflineTime] [datetime] NOT NULL, [MobileOfflineTime] [datetime] NOT NULL, [CreateTime] [datetime] NOT NULL, [Version] [int] NOT NULL, CONSTRAINT [PK_GGUser] PRIMARY KEY CLUSTERED ( [UserID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY] GO SET ANSI_PADDING OFF GO EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'0正常，1冻结，2禁言，3停用' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'GGUser', @level2type=N'COLUMN',@level2name=N'UserState' GO

这段代码为创建一个名为GGUser的SQL Server表，表中包含了用户的基本信息，如UserID、密码、手机号、姓名等。其中，Friends、Groups和CommentNames列用于存储用户的好友、群组和备注名，Signature和HeadImageIndex用于存储用户的签名和头像。UserState列用于表示用户状态，0表示正常，1表示冻结，2表示禁言，3表示停用。最后，代码还添加了对UserState列的注释说明。
