so how can i know that Record Save or error occurs
do ii have to use Linq or SubString and How??

推荐答案

您认为LINQ是什么？你是什​​么意思''substring''？您应该调用数据层，然后检查它返回的值，并编写代码以按预期呈现结果。我认为你正在抛出流行语，不知道它们的意思。

What do you think LINQ is ? What do you mean by ''substring'' ? You should call your data layer, and then check what values it returns, and write code to render the result as you expect. I think you''re throwing around buzzwords with no clue what they mean.

所以我的查询是如何找到意味着我将保存结果字符串_result变量

所以我怎么知道Record Save或错误发生

我必须使用Linq或SubString和How ??



当您调用存储过程来保存日期并且您的存储过程不包含任何错误处理技术时，您将收到必须在应用程序级别处理的错误。





和



让我们考虑一下我正在使用1商店程序，如果记录保存则返回消息

然后

使用Grn No 1和Sr No 3成功记录保存



在您的交易成功完成后从您的存储过程返回1，然后在您的应用程序中返回

"so my is query how to find means i am going to save result in String _result Variable
so how can i know that Record Save or error occurs
do ii have to use Linq or SubString and How??"

when you will call stored procedure to save date and your stored procedure does not contain any error handling technique, you will gotten error which you have to handled in application level.


and

"Let''s Consider I am using 1 store procedure that return message if record save
then
Record Save Successfully with Grn No 1 and Sr No 3
"
return 1 from your stored procedure when your transaction is completed successfully, then in your application

bool _result = Convert.ToBoolean(YourSqlCommand.ExecuteScalar());

之后，查看_result中是否有真值或错误

and after that, see if you have true value or false in _result

if(_result)
{
   // data saved, so show message
   HttpContext.Current.Response.Write("<script> alert('data saved'); </script>");
}
else
{
   // data is not saved, show error or any proper message you want here
}
