If you are using the Microsoft SQL Server for your error log then you should re-create
the ELMAH_Error
table, its indicies and related stored procedures
using the supplied SQL script (see Database.sql
in your distribution).
The script does not contain DDL DROP
statements so you will have to drop
the table and stored procedures manually before applying the script. If you wish to
preserve the logged error data, you should consider archiving it in a backup.
