Purpose:To import the SQL Server error log into a table, so that it can be queried

Written by:Anand Mahendra

Tested on: SQL Server 2000

Limitation: With error messages spanning more than one line only the first line is included in the table

Email: anandbox@sify.com

Example 1: To import the current error log to table myerrorlog
EXEC sp_import_errorlog 'myerrorlog'

Example 2: To import the current error log to table myerrorlog, and overwrite the table
'myerrorlog' if it already exists
EXEC sp_import_errorlog 'myerrorlog', @overwrite = 1

Example 3: To import the previous error log to table myerrorlog
EXEC sp_import_errorlog 'myerrorlog', 1

Example 4: To import the second previous error log to table myerrorlog
EXEC sp_import_errorlog 'myerrorlog', 2
