私のようなユーザーテーブルから1を持っている

Question

データベース列にsmalldatetimeの値を挿入する方法：

Id int Unchecked 
Name varchar(50) Checked 
EmailAddress varchar(200) Unchecked 
Host varchar(250) Unchecked 
Port int Unchecked 
POPHost varchar(250) Checked 
POPPort int Checked 
Password varchar(50) Unchecked 
CreatedDate smalldatetime Unchecked 
user_id int Unchecked 
EnableSSL bit Unchecked 
Count int Unchecked 
SentDateTime smalldatetime Checked 
MaxCount int Checked 

をし、これは次のように選択ごとに特定のフィールドを更新するための保存されたインプロセスである：しかし

USE [EASYMAIL]

    SET NOCOUNT ON; 
    IF @var_name = 'Name'

     UPDATE [EASYMAIL].[dbo].[tbl_From_master] SET [EnableSSL] = CAST(@var_value AS BIT) WHERE (Id = @fromuser_id) 
    ELSE IF @var_name = 'SentDateTime' 
     UPDATE [EASYMAIL].[dbo].[tbl_From_master] SET [SentDateTime] = SUBSTRING(@var_value,4,3) + LEFT(@var_value,3) + RIGHT(@var_value,4) WHERE (Id = @fromuser_id) 
    ELSE IF @var_name = 'Count' 
     UPDATE [EASYMAIL].[dbo].[tbl_From_master] SET [Count] = CAST (@var_value AS INT) WHERE (Id=@fromuser_id) 
    ELSE IF @var_name = 'MaxCount' 
     UPDATE [EASYMAIL].[dbo].[tbl_From_master] SET [MaxCount] = CAST (@var_value AS INT) WHERE (Id=@fromuser_id) 
END 

USE [EASYMAIL] 
GO 

DECLARE @return_value int 

EXEC @return_value = [dbo].[UpdateFromUserField] 
     @fromuser_id = 1, 
     @var_name = N'SentDateTime', 
     @var_value = N'2017-02-20 8:32:12' 

SELECT 'Return Value' = @return_value 

GO 

エラー：

、それは次のように時間を実行する上でエラーを取得しています

Msg 295, Level 16, State 3, Procedure UpdateFromUserField, Line 26 
Conversion failed when converting a character string to smalldatetime data type. 

ここで間違いがありますか？

変更更新私を助けてくださいすることにより

SET [SentDateTime] = SUBSTRING(@var_value,4,3) + LEFT(@var_value,3) + RIGHT(@var_value,4) 

を：

SET [SentDateTime] = CAST(LEFT(@var_value,4) + SUBSTRING(@var_value,6,2) + SUBSTRING(@var_value,9,2)) AS SMALLDATETIME) 

または：

SET [SentDateTime] = CAST(@var_vaule AS SMALLDATETIME)
