我不明白这段代码的错误

Answer 1

更改这些行：

comm.Parameters.AddWithValue("@dob",lb8.Text);
comm.Parameters.AddWithValue("@doj",lb6.Text);

到这些：

comm.Parameters.Add("@dob", SqlDbType.DateTime).Value = Convert.ToDateTime(lb8.Text);
comm.Parameters.Add("@doj", SqlDbType.DateTime).Value = Convert.ToDateTime(lb6.Text);

从文本框接收值时，所有日期时间列都应转换为日期时间，默认情况下返回字符串值。

或者，通过转换dob＆amp; amp;编辑您的SP doj to inserttime in insert query：

CREATE procedure SPInsrailbkgCY (
-- simplified for brevity --     
@doj datetime,          
@dob datetime,
-- simplified for brevity --        
as          
begin
-- simplified for brevity --        
insert into railbkg (  
-- simplified for brevity --
,doj   
,dob 
-- simplified for brevity --         
)          
values           
( 
-- simplified for brevity --
,convert(datetime,@doj)    
,convert(datetime,@dob) 
-- simplified for brevity --
)
