In
this article I will explain how to maintain Error log table in SQL server in
AS.NET application.
Description:
In
previous articles I have explained
SQL: Copy full data of one
table to another using SQL command in SQL Database And SQL:
How to Create table in SQL Database.? And SQL:
How to create Database in SQL server and SQL:
How to generate script of database in SQL Server and Asp.Net:
Bind or Populate Gridview control using Dataset and stored procedure .
Implementation:
1.
Create Table
in SQL Server i.e. Error_log:
CREATE TABLE [dbo].[Error_log](
[Error_id] [int] IDENTITY(1,1) NOT NULL,
[page_Name] [varchar](200) NULL,
[method_name] [varchar](200) NULL,
[line_No] [int] NULL,
[error_Message] [varchar](max) NULL,
[error_date] [datetime] NULL
)
|
2.
Now Create Stored procedure to Insert data:
Create proc Sp_Error_Log
@page varchar(200),
@method varchar(200),
@lineno int ,
@error varchar(max)
as begin
Insert into Error_log(page_Name,method_name,line_No,[error_Message])
values (@page,@method,@lineno,@error)
end
|
3.
Now Create
following method in Class ex. Error.cs:
public static void Create_Error_Log(Exception excep)
{
string ErrorMessgage =
excep.Message;
System.Diagnostics.StackTrace trace = new
System.Diagnostics.StackTrace(excep, true);
string pagename =
trace.GetFrame((trace.FrameCount - 1)).GetFileName();
string method =
trace.GetFrame((trace.FrameCount - 1)).GetMethod().ToString();
Int32 lineNumber =
trace.GetFrame((trace.FrameCount - 1)).GetFileLineNumber();
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["con"].ConnectionString);
con.Open();
SqlCommand cmd = new SqlCommand("Sp_Error_Log", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@page", pagename);
cmd.Parameters.AddWithValue("@method", method);
cmd.Parameters.AddWithValue("@lineno", lineNumber);
cmd.Parameters.AddWithValue("@error", ErrorMessgage);
cmd.ExecuteNonQuery();
con.Close();
}
|
4.
Now Call
this method in catch(ex):
try
{
}
catch (Exception ex)
{
ErrorLog.Create_Error_Log(ex);
}
|
In this
application I will write following information to database table:
Page_Name : Page Name where error occurs
Method_name : Method name in which error occurs.
Line_No : Line number of error .
Error_Message: Error message to save in SQL server Table.
Method_name : Method name in which error occurs.
Line_No : Line number of error .
Error_Message: Error message to save in SQL server Table.
This is good practice
to maintain error log in database. This will help us to record error list.
