When I join to the Dates table, I am now successful in creating placeholders for those dates missing. The values for all the columns from the CannedBackupJobs table are NULL, wherever there is no data for a specific date.....

..............which would be fine if there were ever only one servername.

My fault for not providing/ or thinking about the additional layer of the problem. The DDL I provided should have contained rows with dates for backups that were done for more than one server eg Peaches & Pears.

New DDL INSERT statement

insert into [dbo].[CannedBackupJobs]

values

Each server has it's own unique history of backups, against a continuum of time, sometimes sharing dates with other servers, on which no backups occurred, sometimes not. On those days where neither server was backed up, I need the same date placeholder specifically for Peaches and another for Pears.

Do I do this with a bunch of seperate select statements (with WHERE ServerName = Peaches and with WHERE ServerName = Pears) run against the _Dates table with a UNION ALL to recombine them? Or is there a better way?

Thanks much in advance!
