Nothing ever in the clear!

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.

the query is the same as the one u posted and the timestamp data type is datetime type.  i guess it needs to be converted into var char

No, you should not need to convert to varchar.

Did you replace what I had as [YourTable] with the actual name of your table you are querying?

Did you receive any errors?

Also, Timestamp is actually a reserved word so you may have to put it in square brackets so it knows that is your field name.  Such as :

select * FROM [YourTable]  where [TimeStamp]  >= dateadd(m, -3, getdate())

try this.


select top 10  [TimeStamp] ,  [ScriptName] FROM [YourTable] order by [Timestamp] desc

Please change the table name, run it, and post the results.

Boy, you do have a puzzling situation.
I apologize if my questions will seem obvious but I have to ask anyway because the query I gave you works fine for me.

Could you generate the script for your table and post it?
Please post the exact query you ran.

Is it possible your system date got goofed up?
Try this:
Select dateadd(m, -3, getdate()) as MyMinDate
Is it what you'd expect?

Are you sure you're looking at the correct database when you check the data type of your Timestamp field?

this query returns a single cell like this:
2011-05-12 13:10:11.370

i think this has done the trick:
where TimeStamp >=dateadd(month, -3, getdate())

thanks
