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:
So what are the information we need to log into the table, let's create the table:
CREATE TABLE [ErrorLog]( [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 ) ON [PRIMARY]
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 AS Insert Into ErrorLog( [ErrorNumber], [ErrorMessage], [Severity], [State], [LineNo], [Procedure], [UserName], [Errortime]) 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 AS 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
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
