Handle error in your database base by using using a single procedure

How to handle all the error in sql server database, it is very easy, you will say the same after reading this article. If I ask the same question right now many of us start thinking how we can use it, do we need to create a table, procedure and what would be useful values which should be in this table and how to call the procedure from every procedure, how to page the parameter etc. stop thinking for now.

Here is the steps:

  1. Create a single table
  2. Create a procedure to log all the errors in table
  3. Use Try .... Catch to log the error

So what are the information we need to log into the table, let's create the table:

    [ErrorLogID] [int] IDENTITY(1,1) NOT NULL,
    [ErrorNumber]   [int] NOT NULL,
    [ErrorMessage]  [varchar](8000) NULL,
    [Severity]  [int] NULL,
    [State]     [int] NULL,
    [Procedure] [varchar](200) NULL,
    [LineNo]    [int] NULL,
    [UserName]  [varchar](128) NULL,
    [Errortime] [datetime] NULL

If you can see closely we have everything here, now let's create a procedure to insert all these values without passing a single parameter, What? Without passing a any parameter? yes, see this:

Create Proc LogError
  Insert Into ErrorLog(

  SELECT error_number()
   , error_message()
   , error_severity()
   , error_state()
   , error_line()
   , error_procedure()
   , suser_sname()
   , GETDATE()

See the procedure, do you think we need to pass any value for this procedure, no because I took everything from the different different functions.

Time to use what we have created otherwise it's use less, let try to create procedure simply divide any number by zero(0) and check the table.

Create Proc testlog

Begin Try
  select 10/0
End Try

Begin Catch
   EXEC Logerror
End Catch

In this procedure i try to divide 10 by 0, now execute the procedure test log

EXEC testlog

Now let's check our log table now

Select * From ErrorLog

and here is the log detail

ErrorLogID  ErrorNumber ErrorMessage    Severity    State   Procedure   LineNo  UserName    Errortime
1   8134    Divide by zero error encountered.   16  1   spTest  4   sa  2014-02-22 18:51:19.347
