I was asked this question today...what's the command to check the date of the last time a stored proc was recompiled. I thought it was sp_recompile. It's not..

Is there a command?

dbcc freeproccache
will clear the cache so that everything is recompiled again. unless you are using many complicated queries, the performance hit is not noticeable.

sp's are recompiled if they are not in the proc cache, so if you like, the last compile time is when it entered the cache

the proc cache is clean on a sql server restart. other than   dbcc proccache   telling you some stats about it, I don't think there are other ways of getting exactly what's in there, not to mention whether a specific sp is in there and when.

just ran dbcc proccache. Doesnt say much.

I guess our client needs to clear the cache.

There may be better ways, but on SQL 2005 you can run

select top 10 *
from sys.dm_exec_query_stats

creation_time will contain when the query plan was created (i.e. first executed since restart/cache clear)

That won't show you what the query was though.  You can adapt this for that. If you are all SQL 2005 I'll script it out if you like. (I don't have it written up but I'll do it if you need it)

create table #t (id int identity(1,1), sqlcmd text)

-- Top 10 highest logical IO. Remove TOP to get all queries on the system
select top 10 sql_handle
into #x
from sys.dm_exec_query_stats
order by total_logical_reads , total_logical_writes

select 'insert #t select text from sys.dm_exec_sql_text(', t.sql_handle, ')'
FROM #x t
order by id

Execute output from command above to see highest 10 IO queries.

In sql server 2005,  this will do
SELECT  DB_NAME(dbid) AS DatabaseName
       ,OBJECT_NAME(ObjectID) AS ObjectName
       ,der.creation_time
       ,der.Last_execution_time
       ,Text
FROM    sys.dm_exec_query_stats as der
CROSS APPLY sys.dm_exec_sql_text(der.sql_handle) as dest

Open in new window

Cool. I had tried CROSS APPLY and was getting some error. Forget what it was now. Thought it was a limit of sys.dm_exec_sql_text()

it's sql 2000 but they use sql2005 management to look at sql2000. They dont use enterprise manager.
