I have table named dailysalesReport which contains Thousand of data on daily basis.
I need when I execute the select statement then result automatically saved in a excel sheet.
Kindly someone help me out.

We are trying to figure out root cause of slow running sql server queries hitting/fetching data from one of the database , size 300 GB, hosted on server with below configuration:
Windows server 2003 R2, SP2, Enterprise Edition, 16 GB RAM , 12 CPU'S 32 Bit
SQL server 2005, SP4, Enterprise Edition, 32 Bit.
We have already informed business on the upgrade to 64 bit which would take over a month.
But for the current issue, we are trying to gather the data if we can resolve the memory pressure or finally come to a conclusion to increase RAM.
Action Completed: Re-indexing and update stats are proper for this DB.
As shown below, we have been noticing the semaphore waittype for past 5 days, ran during the load hours:
Few info after below queries: size of buffer= 137272
SELECT SUM(virtual_memory_committed_kb)FROM sys.dm_os_memory_clerksWHERE type='MEMORYCLERK_SQLBUFFERPOOL'and semaphore memory= 644024 per below query
SELECT SUM(total_memory_kb)FROM sys.dm_exec_query_resource_semaphores
Below is some more info gathered from dm_exec_query_resource_semaphores and sys.dm_exec_query_memory_grants dmv's
So from above info gathered and per SP_Blitz data Resource semaphore seems to be the problem.
Is memory 'target_memory_kb' assigned for resource semaphore id's too low, as compared to 16 GB RAM available.
Note* per analysis on 8 hours run 'target_memory_kb' is always under 1 GB, compared to 16 GB available?
what could be the issue here and how to resolve, please suggest
Thanks
Hello!
All started when Sql server error log shows:
The transaction log for database 'databasename' is full due to 'XTP_CHECKPOINT'.
On database which uses as usually 30GB log file.
The LOG file now is 400GB
After searching during 2 days I found too little information(((
It seems, that I have the same problem like in this link, log is growing.
https://connect.microsoft.com/SQLServer/feedback/details/1021865
Microsoft SQL Server 2014 - 12.0.2456.0
Database in SIMPLE recovery,
DBCC LOGINFO shows many rows with State=2
DBCC OPENTRAN show 0 transactions
SYS.DATABASES.log_reuse_wait_desc = XTP_CHECKPOINT
No replications
In-Memory enabled and used
Manual CHECKPOINT shows the error:
Error: 41315, Severity: 16, Checkpoint operation failed.
Is anybody catches the same errors before?
PS. I have restored Database and can run CHECKPOINT command and shrink database. But in several minutes I can't repeat this again because of the sameCHECKPOINT error.

Hi,
We are having a Sql Clustered instance of SqlServer 2008 R2 running
on windows server 2008 R2 with 2 nodes. We have about 88 databases in the instance.
Our servers run on Intel Xeon(R) CPU X5670 @2.94 GHz with 6 cores(12 logical processor).
The servers are having 12GB of RAM.Our network storage is in EMC and for data we are having
a shared voume of 2 TB for the data(for both mdf and ldf files). I would like to know
whether there would be any problem in enabling file streaming through GUI in the clustered
instance. I understand that by creating a table with a file stream coloumn would create a
subfolder in the file stream data container. Once we created a shared folder in the shared
volume(lun) and there was a server reboot in the active node. Should be anticipate any such eventuality.
Are the steps of enabling file stream capability in the clustered instance same as that of enabling it
in a noram instance?
Thanking you in anticipation,
Binny Mathew
Hi,
I've been sent a new version of a database by our data vendor, which is a .mdf file to attach. The vendor has a service that downloads data and inserts it into this database, which we then query.
I detatched the old database and then attached the files they had supplied. This all works fine.
But the new database does not have performance counters. How can I create performance counters for a single database?
To be clear, I've tried unloading and reloading the counters and it doesn't solve the problem. The counters for all the other databases on the server show just fine. It's just this one database that is missing. Subsequent detatch and re-attach
do not recreate the counters.
Thanks,

Hi,
Was wondering if there's a tool for monitoring database file growth. I've been reading up on a number of user created solutions to collect data on a daily basis but wondered if there was any professional software solution for this. I've a number of RedGate tools but none seem to cover this.
Thanks
Hope it Helps!!
Hi ,
I am using a stored procedure to check the availability of a record in a table and deleting the record if exists ,
actually if the user have multiple record i need to delete and store it in removed table , so i used insert with select command to insert into the table , do i need to use a temp table to insert multiple record in removed table .
Thank You

We are in a Database Migration Project.
DatabaseA is set to be migrated. It currently resides in ServerA. In DatabaseA lies an SP, which calls XP_CMDSHELL in it. This SP is being called by a messageQueue.
In ServerA, we do have a Local Windows System user as the application login. ( ServerA\LocalLogin). This login does not have any sysadmin privileges and only is a member of db_datareader and a custom executesp roles of the DatabaseA.
This database Needs to be migrated to ServerB. when migrating this to ServerB, the only change is that the LocalSystem user is replaced by a Domain User. The application is supposed to connect to the DatabaseA via the Domain User. (Domain\DomainUserB)
However, Once the database is migrated to ServerB, we get the following error related to the message queue:
The xp_cmdshell proxy account information cannot be retrieved or is invalid. Verify that the '##xp_cmdshell_proxy_account##' credential exists and contains valid information Message Queue Service Broker
This error never happen to come in ServerA and is no proxy_accounts are configured in it. The logins (ServerA\LocalLogin and Domain\DomainUserB) are identical in terms of privileges. What would be the problem ? Why is this error popping only in
ServerB ? How can i overcome this without creating a proxy account ?
Security Context of the MessageQueue is ExecuteAsUser with a principal of dbo.
Both the servers are SQL Server 2008, and Windows Server 2008.
Hello,
I am doing some internal testing to learn how dbcc page reads the data and I find it strange that I can see uncommitted data on the page.
I am not sure why i would see that information. My initial thought was may be check points, wrote the data on the page and I set the recovery intervals high (test system) and started a extended events trace to monitor check points and Check
point were not issued during this period but I still see the uncommitted reads.
I do not think it because of lazy writer either. can someone please explain on this.
you can try the below demo to reproduce the issue.
Create Database SSMS2012
GO
USE SSMS2012
go
Create Table SSMSt(sno int primary key identity(1,1),sname varchar(6))
go
Insert into SSMSt
values('Better')
go 100
select * from sys.dm_db_database_page_allocations(db_ID('SSMS2012'),object_ID('SSMSt'),null,null,'limited')
dbcc traceon(3604,-1)
--use the allocated_page_page_id where is_iam_page=0
dbcc page(5,1,228,2)
--sesssion 2 . see the data is not committed yet.
begin tran
update ssmst set sname='qazxsi'
--session 1
--run the dbcc page again. we can see the new uncommitted data.
dbcc page(5,1,228,2)
clean up
--session 2
Commit
use [Master]
go
--Session 1
use master
go
Drop database SSMS2012
Thank You.Hope it Helps!!
Hi All.. i have had one database was in suspect mode and i have changed the status to Emergency Mode and i have run the DBCC checkdb and command didn't gave any error.. after this i have tried to change database to Single_user mode, but command running successfully, but database status is still showing as Emergency mode only.. i have tried for multi_user mode too..
Also, i have tried to run the command to bring online, but command running for long time with Suspended status..
Could anyone help me on this??
We have a daily job which generally takes around 12 hours. After a couple of weeks the duration starts to creep up and we are able to restore it to its normal duration by restarting the sql server service.
Why does restarting the service seem to speed up the job? seems a little like using a bulldozer to crack a nut. Would like to understand what exactly is happening when we restart to improve the duration. Any ideas?
Hi All,
SQL Server 2008R2 (10.50.4279) I've noticed a process that hungs, the wait type was "PREEMPTIVE_OS_PIPEOS" and the process itself was a SQL Server Agent job.
First thing is that in Job Activity monitor I could not see any job running.
I've tried to kill the spid from Activity monitor but now the SPID is stuck in "KILLED/ROLLBACK" state, and the wait is always "PREEMPTIVE_OS_PIPEOS".
I've checked that the job executes a stored procedure that invokes sp_send_dbmail with an attachment, I've tried to restart the SQL Server Agent, but the spid is always there.
How can I kill the process?
Hi,
In my infra i have an instance with 10 Databases. And i am going to migrate 4 of them to new hardware.
I am planning to use Backup/Restore method to move the DBs to new hardware.
I will put the DBs in old server to SINGLE_USER mode.
Can you please tell me how to check the complete data is migrated to new server ?
I dont want to miss any transactions (data) from application.
And also how to compare the data between the old and new DBs ?

Vinodh Selvaraj
On a database a number of indexes are missing. It is killing the performance of the SQL Server. I want to create a clustered index on the biggest table that has as size of 1TB. How much transaction log space is needed to create the clustered index?
Is it possible to reduce the amount of transaction log space that is needed?
Does the size of the selected fields make a difference?
Hello everybody!
After upgrading from Microsoft SQL Server 2008 to Microsoft SQL Server 2012 we faced with CLR allocations problem. In earlier versions of SQL Server CLR allocations were in virtual address space (also known as "Memory-To-Leave"). In SQL Server 2008 you can configure max_server_memory for SQL server, prevent starting other processes on server and it will guaranty you that your CLR will not unload due memory pressure (use “lock pages in memory”)
In SQL Server 2012 there were big changes in memory management. The key change for us was relocating (or splitting) CLR allocations from "Memory-To-Leave" to "max server memory (MB)". And now you can get “AppDomain 2 (work5nt.dbo[runtime].1) is marked for unload due to memory pressure.” message in server log with future unloading AppDomain when “Query Execution Memory” grows fast.
During our stress tests of SQL server 2012 I had rapid growth of “Granted Workspace Memory (KB)” to more than 50% of max_server_memory (72GB). Top wait on server was RESOURCE_SEMAPHORE and «SQL Memory Manager:Memory Grants Pending» growth up to 154 processes.
Information from log file about unloading:
2015-03-26 19:49:20.15 spid18s AppDomain 13 (work5nt.dbo[runtime].82) is marked for unload due to memory pressure.
2015-03-26 19:49:20.15 spid18s AppDomain 12 (mssqlsystemresource.dbo[runtime].81) is marked for unload due to memory pressure.
2015-03-26 19:49:20.15 spid19s AppDomain 13 (work5nt.dbo[runtime].82) unloaded.
2015-03-26 19:49:20.15 spid18s AppDomain 12 (mssqlsystemresource.dbo[runtime].81) unloaded.
2015-03-26 19:49:20.83 spid419 AppDomain 14 (work5nt.dbo[runtime].94) created.
2015-03-26 19:49:20.86 spid245 Unsafe assembly 'log, version=1.0.5498.27124, culture=neutral, publickeytoken=bb8adbf0186b255f, processorarchitecture=msil' loaded into appdomain 14 (work5nt.dbo[runtime].94).
2015-03-26 19:49:20.86 spid419 Unsafe assembly 'seed, version=1.0.5539.32591, culture=neutral, publickeytoken=4d4e4ff7fd85d31c, processorarchitecture=msil' loaded into appdomain 14 (work5nt.dbo[runtime].94).
2015-03-26 19:49:20.89 spid245 Unsafe assembly 'log, version=1.0.5498.27124, culture=neutral, publickeytoken=bb8adbf0186b255f, processorarchitecture=msil' loaded into appdomain 14 (work5nt.dbo[runtime].94).
2015-03-26 19:49:20.91 spid419 Unsafe assembly 'seed, version=1.0.5539.32591, culture=neutral, publickeytoken=4d4e4ff7fd85d31c, processorarchitecture=msil' loaded into appdomain 14 (work5nt.dbo[runtime].94).
Our product can get critical error after unloading CLR. (We are working on that problem but it’s not SQL server side problem.)
Main memory counters during stress test (perfmon):
Name | Average | Min | Max |
Total Server Memory (KB) | 75 783 960 | 75 774 432 | 75 880 536 |
ReservedServerMemory (KB) | 18 474 365 | 9 028 744 | 35 325 584 |
GrantedWorkspaceMemory (KB): | 27 173 700 | 16 992 392 | 51 791 136 |
Reserved/Granted Ratio | 0.68 | 0.53 | 0.68 |
So we can see, that highest Reserved Server Memory more than 46% of Total Server Memory! And it is strange.
At the end I have several questions:
Here the first one: How can I avoid unloading CLR due memory pressure on SQL server 2012?
Second one: Can I configure “Reserved Server Memory” for query or server?
And the last one: Is there any extended events to reveal which query consumed a lot of memory? I found sort_memory_grant_adjustment but it does not work or I can’t configure it right.
