Problem
We've been having a number of issues with our indexes lately which our DBA team has attributed to statistics not having been run recently. This has made me wonder - how can I check if statistics have been recently updated via SQL Management Studio?

I'm using the following but receiving a syntax error:
The error I'm receiving is:
Why is this?

Or you may want to execute the following query:
SELECT t.name TableName, s.[name] StatName, STATS_DATE(t.object_id,s.[stats_id]) LastUpdated
FROM sys.[stats] AS s
JOIN sys.[tables] AS t
ON [s].[object_id] = [t].[object_id]
WHERE t.type = 'u'Code Snippets
