sql server 2008 dbmail error sp_send_dbmail - cannot insert null value into 'last_mod_user' in table sysmail_mailitems

Our dbmail got hosed and I'm trying to resolve the issue.

I've recently recreated sp_send_dbmail, but am not getting an odd error regarding a null value in last_mod_user column in开发者_如何转开发 table msdb.dbo.sysmail_mailitems (error 515)

last_mod_user in msdb.dbo.sysmail_mailitems should have a default defined on it. Has that gone missing on your install?

ALTER TABLE [dbo].[sysmail_mailitems] ADD  DEFAULT (suser_sname()) FOR [last_mod_user]

Here's my msdb's [sp_send_dbmail] stored proc on PasteBin. Taken from SQL Server 2008 SP1.

The INSERT statement curiously doesn't include a value for last_mod_user! Line 364 on PasteBin.

Your error sounds correct; the field last_mod_user is defined as non nullable.
