SQL SEVER: How to make an Entry in Event Viewer using SQL SERVER

04/02/2009
Today I came across the situation where I need to following scenario.

I need to make entry in Event Viewer when there is an error in Stored Procedure.

I wondered to do this, but finally I come up with the solution. SQL is much powerful.

SQL provides us to make an entry in Event Viewer by two ways:
1. using XP_LogEvent

2. By Raiserror WITH LOG

Lets first see the way using XP_LogEvent:

Here I have created one SP which will raise an error “Divide by zero error encountered.” as I tried to do “10 / 0”.

CREATE PROCEDURE TestEventViewer
AS
BEGIN TRY
    SELECT  10/0
END TRY
BEGIN CATCH
    PRINT ERROR_Message()
    DECLARE @msg VARCHAR(100)
    SELECT @msg = ERROR_Message()

    EXEC xp_logevent 60000, @msg, informational

END CATCH

Lets Execute this SP:

EXEC TestEventViewer

This will write entry in Event Viewer. Now open Event Viewer. You can find Event Viewer at Control Panel –> Administrative Tools –> Event Viewer.

You will get en entry of Error there.

171

So we can do this by Extended Stored Procedure: “xp_logevent”.

Let see the parameters of this Procedure.

First Parameter: “60000” is the Error Number

Second Parameter: “@msg” is the message to be displayed in Event Viewer.

Third Parameter: “informational” is the Error Level. It could be “informational”, “Error”, “Warning”.

Now, Lets see by another way By Raiserror WITH LOG:

It is the same way as we used Raiserror to Raise an Error.

CREATE PROCEDURE TestEventViewer
AS
BEGIN TRY
    SELECT  10/0
END TRY
BEGIN CATCH
    PRINT ERROR_Message()
    DECLARE @msg VARCHAR(100)
    SELECT @msg = ERROR_Message()

    RAISERROR(@msg, 11, 1) WITH LOG

END CATCH

Lets Execute this SP:

EXEC TestEventViewer.

So By these ways we can make an entry to Event Viewer.

Let me know if it helps you in any way
