Error....................
Invalid object name 'fbmssms.bmsstudents'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: Invalid object name 'fbmssms.bmsstudents'.
Source Error:
Line 436: cmd.Connection = con;

Connection was there. Even my same coding is running in another page in same style. Here I don't know why it is not working.
解决方案
INSERT INTO [fbmssms.bmsstudents]...无效的对象名称“fbmssms.bmsstudents”。
这里有几种可能性。如所写，该INSERT语句指向一个[fbmssms.bmsstudents]在连接对象指向的任何数据库中命名的表。
如果您实际上是指bmsstudents架构中的表fbmssms，请使用 [fbmssms].[bmsstudents].
如果您的意思是bmsstudents数据库中默认模式中的表fbmssms，请使用[fbmssms]..[bmsstudents]或[fbmssms].[dbo].[bmsstudents]（假设这dbo是数据库的默认模式）。
如果您指的是名为 的表[fbmssms.bmsstudents]，则您可能连接到了不正确的数据库。将数据库名称和模式添加到表名中，例如[MyDatabase].[dbo].[fbmssms.bmsstudents].
