这有什么问题吗？ ： [英] What is wrong with this please? :
问题描述
我看了这个，只是不知道为什么错误是未处理的
类型''System.Runtime.InteropServices.COMException''
发生在db2sql.exe中
附加信息：无法将值NULL插入列
''CitatedDateTime''，表''tsNess .dbo.tblTravelDetail '';列没有
允许空值。 INSERT失败。
除了@@身份之外，这个语法与我工作的其他
程序完全相同：
对象记录受影响;
string strSQL2 =" INSERT INTO tblTravelDetail（MemberID）" +
" VALUES（''" + TxtMLV.Text.Trim（）+"''）" +
" SELECT @@ IDENTITY" ;
cnn2.Execute（strSQL2，out recordsEffected，0）;
谢谢，
Trint
I''ve looked this over and just don''t get why the error is "An unhandled
exception of type ''System.Runtime.InteropServices.COMException''
occurred in db2sql.exe
Additional information: Cannot insert the value NULL into column
''CreatedDateTime'', table ''tsNess.dbo.tblTravelDetail''; column does not
allow nulls. INSERT fails."
This syntax, except for the @@identity, is exactly the same in my other
programs that work:
Object recordsEffected;
string strSQL2 = "INSERT INTO tblTravelDetail(MemberID) " +
"VALUES (''" + TxtMLV.Text.Trim() + "'')" +
"SELECT @@IDENTITY " ;
cnn2.Execute(strSQL2, out recordsEffected, 0);
Thanks,

推荐答案
看起来你有一个必填字段，那个表没有填充。

It looks like you have a required field for that table that hasn''t been
populated.

好的，
这次我包含了createddatetime字段，错误继续发生在
另一个字段：
不能将值NULL插入列''TravelEventId''，表格
''tsNess.dbo.tblTravelDetail'';列不允许空值。 INSERT
失败。
谢谢，

Ok,
I included the createddatetime field this time and the error went on to
another field:
"Cannot insert the value NULL into column ''TravelEventId'', table
''tsNess.dbo.tblTravelDetail''; column does not allow nulls. INSERT
fails."

您需要为不支持NULL值的所有列赋值
查看表格定义，你会知道哪些字段是
那些。

You need to give values to ALL columns that do not support NULL values
take a look at the table definition and you will know which fields are
those.
