    Hi to all,

    I am using below query to find last executed queries. but  I want to filter only the records from a particular Database. How do I do it? 

    SELECT deqs.last_execution_time AS [Time], dest.text AS [Query]

    FROM sys.dm_exec_query_stats AS deqs

    CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest

    CROSS APPLY sys.tables as tab

    where tab.type like 'u'

    ORDER BY deqs.last_execution_time DESC

    Thanks

    Thanks for reply, I want to filter only the records from a particular Database. How do I do it? 

    Hey! My post did give you answer. You only had to check out Books Online and play around.

    Oh well, now I had the time to test it, and it turns out that you need to use two alternate filters:

    SELECT deqs.last_execution_time AS [Time], dest.text AS [Query] FROM sys.dm_exec_query_stats AS deqs CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest CROSS APPLY sys.dm_exec_plan_attributes(deqs.plan_handle) depa WHERE (depa.attribute = 'dbid'AND depa.value = db_id('yourdb')) OR dest.dbid = db_id('yourdb')

    The filter on dm_exec_plan_attributes works for ad-hoc queries, but not stored procedures. In this case dbid in dm_exec_sql_text works, but this column is not set for ad-hoc batches.

    And note that this is still a little restrictive. Say that someone is in the database otherdb and runs the query:

    SELECT yadayada FROM yourdb.dbo.tbl

    The query above will not list this table, because dbid in plan_attributes is the database that was the current database when the query was submitted.

    One way to cover this situations is to add the condition:

    OR dest.text LIKE'%yourdb.%'

    Thanks a lot i got last executed query From your query. But  i want database name and only user_table querys  in that query please tell me how can i get that ?

    How do you mean, you want the database displayed in the result set? But you are already filtering on it.

    Naomi's expression can be corrected to:

    coalesce(db_name(dest.dbID), db_name(cast(depa.value asint)))

    And what do you mean with "only user_table querys". You don't want to see queries that retrieve metadata from sys.objects and other tables? I guess you could "NOT LIKE '%sys.%'" but I will have to admit that I would be wary of this, as it may not be reliable.

    I don't think "CROSS APPLY sys.tables" will do you any good, as it will explode the result set.

    As for your question, there is a dbid column in sys.dm_exec_sql_text, but as I recall it is only set for stored procedures, not ad-hoc batches.

    Instead you have to go sys.dm_exec_plan_attributes and filter by the dbid attribute.

    I don't have the time to write a query for you right now, but Books Online can take you a long way.

    As I said in my original reply:

    SELECT deqs.last_execution_time AS [Time], dest.text AS [Query] FROM sys.dm_exec_query_stats AS deqs CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest CROSS APPLY sys.tables as tab where tab.type like'u'and dest.dbID = db_id('MyDBName') ORDERBY deqs.last_execution_time DESC

    However, this may restrict too much info as for add-hoc queries dbID may be NULL.

    Hi Naomi,

      Thanks for reply. When i had that in query i am geting this error

    Msg 260, Level 16, State 3, Line 1

    Disallowed implicit conversion from data type sql_variant to data type int, table 'sys.dm_exec_plan_attributes', column 'value'. Use the CONVERT function to run this query.

     

    Thanks

    Well, here is what I have - most of the queries are Ad-hoc, so we can not find the Db Name reliably:

    SELECT * FROM(SELECTCOALESCE(OBJECT_NAME(s2.objectid,s2.dbid),'Ad-Hoc') AS ProcName,execution_count, (SELECTTOP 1 SUBSTRING(s2.TEXT,statement_start_offset / 2+1 , ( (CASEWHEN statement_end_offset = -1 THEN (LEN(CONVERT(NVARCHAR(MAX),s2.TEXT)) * 2) ELSE statement_end_offset END) - statement_start_offset) / 2+1)) AS sql_statement, last_execution_time, db_name(s2.dbid) as DbName FROM sys.dm_exec_query_stats AS s1 CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS s2 ) x ORDERBY last_execution_time DESC

    Yes, it's a known fact that DMV queries are resource expensive. Ted Kruger has a blog on this topic

    and also Jonathan K mentioned in his session that Extended Events are not as resource extensive as DMVs.

    What we are looking for is to be able to see what parameters was passed to specific stored procedure call

    That level of detail is not available from the DMVs, which contain aggregated statistics. You need to run a trace (Extended Events or deprecated SQL Trace) to capture RPC completed events of the desired activity. If you are calling the proc as an ad-hoc batch passing literals as parameter values, capture the batch completed event instead.

The Get last query plan command returns the detailed internal description of the query plan for the last query carried out on the data. For more information about query descriptions, please refer to the documentation of the DESCRIBE QUERY EXECUTION command.

This description is returned in Text or XML format depending on the value passed in the descFormat parameter. You can pass one of the following constants, found in the “Queries” theme:

ConstantTypeValue
Description in text formatLongint0
Description in XML formatLongint1


This command returns a significant value if the DESCRIBE QUERY EXECUTIONcommand has been executed during the session.

The description of the last query plan can be compared to the description of the actual path of the last query (obtained using the Get last query path command) for optimization purposes.

Get all the queries executed in the last week in SQL Server [closed]

I don't expect you to be on 2016 yet as it's been released only very recently (at the time of writing) but if you have a 2016 server and you have Query Store enabled for your database, you can review your queries there.

Have a look at the documentation for Query Store which lists the following example use cases:

  • Determine the number of times a query was executed in a given time window, assisting a DBA in troubleshooting performance resource problems.

  • Identify top n queries (by execution time, memory consumption, etc.) in the past x hours.

If you want to have a log of your queries for future review you could look into Extended Events or server side traces, depending on your server version.

If you are running SQL 2005+ you can log queries using this article explaining server side trace.

If you are running a version more recent than 2008 you can use Extended Events which would be recommended over server side traces.

Look at the query posted here by Paul Randal showing you how to log expensive queries using Extended events. You could modify the from that query to log all queries.

That being said I don't think it's a good idea to log ALL of your queries. If you have a fairly active production system that would really slow your system down. Have at least a few filters, and log as few data as possible.

If you don't have any logging set up there is no way you can retroactively and reliably get that information.

The closest you can get is querying the plan cache with something like:

That would list you all queries executed in the last week that still have the plan in cache along with the last execution time and database name (unless it's prepared statement).

But you need to realize this is no guaranteed way to get you ALL of your queries as there are multiple reasons a query could have been executed but never or no longer have a plan in cache.

For example there are ways to drop the entire plan cache or evict a single plan

If optimize for ad hoc workloads is active, a query which has only been executed once will not be retrieved by this query and plans that were once stored in cache can be evicted from the cache by anything that cause a plan recompile such as updated statistics, DDL statements, index rebuilds etc. Read through this whitepaper listing all circumstances that cause plan recompilation.

Query: Opens in Last 30 Days

Write a query to find subscribers who opened emails sent from the Marketing Cloud in the previous 30 days.

This query finds subscribers who opened an email in the last 30 days, regardless of how many sending jobs used that EmailID.

Considerations

  • This query finds unique opens only.
  • This query assumes that your account is not part of an Enterprise 2 account.
  • Extending the date range beyond one month is not recommended.

Modifications

  • To capture all opens, remove line 14, KeyGenSumo.com | Last queries.
  • If the account is part of an Enterprise 2 account, alter line 11 to be:
  • To capture clicks, bounces, complaints, or unsubscribes rather than opens, alter each location that includes to include the item you want to capture. For example, KeyGenSumo.com | Last queries, to capture clicks, name the data extension KeyGenSumo.com | Last queriesname the query and name the data extension field. Change each instance of in the query tosuch as lines 5 and 9.
  • To pull a particular time frame, alter line 15. As an example, this captures activity from 30 to 60 days ago:
  • To capture a larger time frame, alter line 15 to include any time frame that is less than 180 days. Large volumes of data can result in long-running queries and failures due to timeout.
  • To capture sends only, alter every location that says to be. Remove line 14.
