In SQL Server 2005/2008, how can I tell if Snapshot Isolation is turned on? I know how to turn it on, but I can't find the incantation to get google to tell me how to query the state of the Snapshot Isolation option.

right click on the databases directory in the object explorer and start powershell. type:
get-childitem|select name, snapshotisolationstate
and press return

    wow, is the PS really necessary? – Nick Kavadias Feb 26 '10 at 14:27

Powershell, really? what's wrong with good ol' fashioned T-SQL?

sys.databases is what you want. It has human readable description columns like snapshot_isolation_state_desc

SELECT snapshot_isolation_state_desc from sys.databases 
where name='adventureworks'

    No, not wholly necessary but I'm just starting to learn PS so took a look to see how it could be done and thought I'd share .. ! – Fatherjack Feb 26 '10 at 15:14
  • as much as i hate to admit it, it is cool – Nick Kavadias Feb 26 '10 at 15:22
  • to be honest, I'm struggling to see its going to be a lot of use to me, we only have 30ish servers. If I wanted the snapshot isolation from every database on every server then I guess PS might be better than T-SQL.. for now I'm seeing it just as an alternative, I'll use it here and there I expect. – Fatherjack Feb 26 '10 at 18:05
  • I can't edit because it's less than a six-character change, but for other confused souls who copy and paste the query, note that it should be sys.databases and not sys.database. – Mark Sowul Jul 14 '11 at 16:39

Expanding on nicks response from above..

The following will return information about all of your databases

    select name
        , s.snapshot_isolation_state
        , snapshot_isolation_state_desc
        , is_read_committed_snapshot_on
        , recovery_model
        , recovery_model_desc
        , collation_name
    from sys.databases s

Or using T-SQL code:

SELECT
'Current Isolation State:' [ ],
CASE is_read_committed_snapshot_on
        WHEN 1 THEN 'ON' ELSE 'OFF'
    END AS [Read Committed Snapsot State]

FROM sys.databases WHERE name = 'MyDatabaseName'

    This answer is for read_committed_snapshot, not for Snapshot Isolation Level like the OP requested. They are two different things. – Kevin Kalitowski Jul 9 '16 at 13:02
