I can use Profiler to see database usage activity. However, in addition to it, is there a good query I can use to see whether user databases are being used (last select, last update, last alter or last delete etc., with date/time stamp)?I am looking for both SQL2000 and SQL2005 as we need to decommission some of the older servers.
View 6 RepliesI am using SQL 2012 and I am trying to find buffer cache usage by DB objects within a particular DB.
I am running the following query
select
name as DB,
objname as db_object_name,
COUNT(name) as cache_page_count,
COUNT('x')*8.0/1024 as size_mb
[Code] ....
Following are the results:-
DB db_object_name cache_page_countsize_mb
TEST_DBNULL 428 3.34375
TEST_DBsysobjvalues 369 2.882812
TEST_DBsyscolpars 44 0.34375
TEST_DBsysssislog 38 0.296875
....
.....
Question- Why am I getting 428 pages for which there is no corresponding DB object? Why are so many pages present in sys.dm_os_buffer_descriptors but are missing from sys.allocation_units.

I have looked around quite a bit, but mostly what I have found is looking to see if a table is used or if a column is in a stored procedure and honestly most of what I have seen does not work.
I want to reduce our nightly import by removing any columns that are not being used. We insert into our staging tables, Stage1 for example. And say Stage1 has column1 and column2. If those columns are not being used, then I want to remove them from Stage1. The only catch is that every Stage1 table has a v_Stage1. v_Stage1 should have all the columns from Stage1, but doesn't always. So I need to know what columns from Stage1 are used somewhere other than v_Stage1 and what columns from v_Stage1 are not used.

I want to create a lot of index for my database for performance.
But I need find memory usage by indexes.
How to find memory usage by index in sql server?
Suppose we have the following table in our database;
CREATE TABLE [dbo].[PERMISSION](
[ID] [int] IDENTITY(1,1) NOT NULL,
[USERID] [int] NOT NULL,
[STARTTIME] [smalldatetime] NOT NULL,
[ENDTIME] [smalldatetime] NOT NULL,
[REASON] [nvarchar](250) NULL,
[PERMISSIONTYPEID] [int] NOT NULL,
[code]....
This code works pretty well. But I don't want to do this with "select" since there is OUTPUT clause in T-SQL. So the CommandText property will be changed into this;
command.CommandText = @"insert PERMISSION
output INSERTED.ID, INSERTED.CREATETIME into @outID, @outCREATETIME
values(2, getdate(), getdate(), 'sdfg', 1, DEFAULT);";
well, not only this statement gives an error while executing; but also, no such usage defined in the
documentation of OUTPUT Clause. Actually the documentation tell us to use Temporary Tables for that. So I have to change CommandText into this;
command.CommandText = @"DECLARE @MyTableVar table(ID int, CREATETIME smalldatetime);
insert PERMISSION
output INSERTED.ID, INSERTED.CREATETIME into @MyTableVar
code]....
No temporary tables required; thus, no "type spesific" things required. This way is easier to create dynamic queries though. Only,the RETURNING INTO clause.So, I was wondering; why MS-SQL (T-SQL) forces users to "declare a temporary table (type specific)" and "execute select on the temporary table in order to assign values to output parameters" while using "the OUTPUT Clause". Comparing to the Oracle's sample I'm just using "the RETURNING INTO Clause in order to assign values to output parameters" and that's it; very easy and dynamic. To Summarize, Oracle's RETURNING INTO Clause is better than MS-SQL's OUTPUT Clause, but in fact they're doing the same job.
My group is trying to ensure that there is a sufficient amount of cushion between the space allocated and the current size of a database. I know that I can check this using the Enterprise Manager. Is there a stored procedure or a systems table that holds this information. I know that sp_spaceused will give me the unallocated space, but i want the allocated space. Any suggestions?

Hi,
I was wondering if there was a SQL query I could run that would list all the current jobs in a SQL 2005 database? I would like to check to ensure a job exists before I call it, but was having trouble finding a way to determine if it existed.
Thanks for any advice!

I am trying to run a SQL query from a Different Datawarehouse DB on the same server but getting error:

In my procedure I need to pull data from a database which is on other server and domain.
As usual I have used the below query but having troubles with mode of authentication.
SELECT * FROM OPENROWSET('SQLNCLI', 'Server=x.x.x.xsyz;Trusted_Connection=yes;','SELECT top 10 * FROM pcm.stats.visits') AS a
I get the below error:
"Login failed. The login is from an untrusted domain and cannot be used with Windows authentication"
I understand from the error that the domain and mode of authentication is different.
I use windows auth and we are given sql auth on the remote server which is on different domain.
I was suggested to use 'sp_addlinkserver' to link the remote server and query the data.
I am just curious to know if we can succeed through link server, is there any script to use sql authentication of remote server in my procedure and pull the data.

Hello, When I am seeing SQL Server 2005 Management studio Server Dashboard> I am seeing my(USERS) databases and msdb database usage is very small % of in CPU Usage(%), Logical IO Performed (%) Usage pie chart.
90% of Total cpu usage is showing for Adhoc Queries. what excatly this means in Dashboard? if application uses more than it would have shown in Database level or not?
sicerely this dashboard is good, if any one is watching daily, please advice their experiences here.
Thanks in advance. Hail SQL Server!
I have a table that has Serial numbers and MSDSID numbers and many other fields in the table.
What I need to figure out is if the table contains a distinct Serial number with different MSDSIDs.
So If I have in the table
Serial MSDSID Date Size...
001 20 1/1/2015 5
002 21 1/1/2015 3
001 22 2/1/2015 1
003 21 3/1/2015 1
004 23 1/15/2015 5
003 22 1/20/2015 6
004 23 2/21/2015 5
002 21 4/25/2015 4
I would like the results to show:
Serial Count
001 2 the count is 2 because Serial 001 has an MSDSID of 20 and 22
002 1 the count is 1 because Serial 002 only has MSDSID 21
003 2 the count is 2 because Serial 003 has an MSDSID of 21 and 22
004 1 the count is 1 because Serial 002 only has MSDSID 23
It would be even better if the results just showed where the count is greater than 1.
