Performance Issue with INSERT..SELECT statement in SQL Server 2017 version 14.0.3048 Express Edition.
Hello Everyone,
I am facing a peculiar performance issue on SQL Server 2017 version 14.0.3048 Express Edition.
I have upload the DB backup, Test Query and Query Results on Onedrive.
DB Backup (1.5 MB): https://1drv.ms/u/s!AuV9gXqFVffxhGdGu57j7sGfV7MQ
Test Query(1 KB): https://1drv.ms/u/s!AuV9gXqFVffxhGk2IBl5xfcWx9is
Query Result (1 KB): https://1drv.ms/t/s!AuV9gXqFVffxhGjP5C7stsKAv9St
In the Test Query there are two commands, COMMAND 1 and COMMAND 2.
In the Query Result we can see that:
COMMAND 1 takes 89968 ms = 89.9 seconds (approx), and COMMAND 2 takes 115296 ms = 115.2 secoconds (approx).
The result of COMMAND 1 is a single value (183).
The only difference between COMMAND 1 and COMMAND 2 is: COMMAND 1 returns the result to the client, where COMMAND 2 stores the result in a table.
Why does SQL Server take and extra (115.2 - 89.9) = 25.3 seconds to store a single value (183) is the perm table called Temp? Any guess?
Thanks!

How to disable default constraint synchronization on sql server publisher article
I have configured a sql server transnational replication. it includes one table A, and when I add a default constraint for one column of table A on publisher, it will sync to subscriber object by default.
Is there any one option to disable this behavior. just because the data on subscriber table should be from publisher database, there is no need to sync all these constraints to subscriber.It does not make sense.

Non-yielding Scheduler first time to happen on a new server
I have been running a stable database for 1 year and recently I moved to a new server that uses NVME drives.
Just after 3 days with the new server, I noticed the database performance is very slow and alot of dumps and event logs are being created
I am using Windows server 2016, MSSQL 2012 SP4 with latest updates.
I already tried DBCC checkdb with no errors and like I said the same configuration was stable for 1 year without a single crash and I just moved the same configuration to a new server that use NVME drives.

Update Statistics in multiple SQL Agent jobs
What is the impact of updating statistics using multiple statistics maintenance jobs? I want to test Ola Hallengren's @UpdateStatistics, but I already have a native SQL Server maintenance task for statistics update. I know, the obvious is disable
one or the other while testing. But just curious what impact multiple jobs might have.

Windows 2016 SQL Server STD after update reverts back to older restore point
Hi All,
I hope you can help, I'm having a real problem with my SQL server 2016 VM (standard), when i do the windows update and restart the VM it somehow reverts the database's back to a version from over a month ago. So i have to quickly restore the backup db before anyone writes anything to the "Old version" of the db. which is mad!
I dont see anything in the event logs to indicate what the issue is and it doesnt happen any other server i have - its a real head scratcher!
Any one got any ideas?
Cheers

Always ON --- SQL authentication user
I noticed that I have to created same username/password as SQL login for a database in Always ON group, but after adding a new database to the AG group, on secondary node, the database is read only and the SQL login cannot be mapped to the sql user inside the database, the question is will the database automatically mapped the the sql login on secondary node in the case of failover? I don't think it will as the user being created on secondary node have different sid despite they have same user/pass.
So question, how to handle the databases in AG group with application access by sql authentication?
my thought would be copy the sql login with same SID on primary node and copy it to secondary, will that work?↧

Publishing Web Services from SQL Server 2014
Hi,
I am currently using SQL Server 2014 and need to publish a view as a web service for consumption by an ETL tool.
I have followed all the steps mentioned under generating and publishing scripts wizard for SQL Server and getting the error below:
Client found response content type of '', but expected 'text/xml'.
The request failed with an empty response. (System.Web.Services)
I’ve reinstalled the Web Deploy using the Recommended MSFT installer tools via the web and tested again locally and it’s still returning the same message as above.
Any help/guidance would be appreciated.
Thanks!

Getting contents of one database into another database with exceptions?
Hello,
we have two databases, productive and development. We need to clone the contents of the productive database into the development database to be able to test stuff on actual cases.
What we want to do is to basically clear all content from the development database, but leave the structure intact, and then fill it with the content of the productive database. So it is changing content without changing the tables and stuff. The tables
are the same in both database, but one - the development database has an additional table. This table and its content must not be changed.
Question is, if I now empty all tables in development (but the exception), can I use the backup and restore function of the management studio to fill the development database's tables with the content of the productive database's table? If not, is there another way to do this without too much effort?

Why have multiple nonclustered indexes.
Hi,
This might be a simple question, but I still need to ask it.
Why is it not sufficient just to have one nonclustered which covers every column instead of having lot of little indexes with different column combinations?
Thanks,

Import of Microsoft Distributed Transaction Coordinator (MS DTC) transaction failed: 0x8004d00e(XACT_E_NOTRANSACTION).
Hi
I have upgraded an SQL 2012 server to SP4 and 24 hours after the upgrade a had a spate of 4 of the following errors in the SQL event log.
Import of Microsoft Distributed Transaction Coordinator (MS DTC) transaction failed: 0x8004d00e(XACT_E_NOTRANSACTION).
Error: 8509, Severity: 16, State: 1.
The server has a second instance of SQL2008 on it, but the error is reporting from the 2012 Server.
The server is not part of a cluster.
SAGECRM is the software using jTDS to talk to a database on the server.
Does anyone have any ideas what may be causing this, as all other links point to it occuring only on clusters and this is not a cluster.
Thanks in advance

In-memory oltp - Checkpoint files not getting recycled
We have in-memory OLTP database with just one table (memory optimized). Since last 2 weeks checkpoint files are not getting flushed unless we restart services.
We have been using this table for last 2 years with no issues till earlier this month. Database just have one table which has 400K records and size of table is 500 MB.
We use this table to store user sessions and on an average we get insert/delete 60K records everyday. Number of selects is much higher but not sure if that would impact size of checkpoint file.
Below are questions we are puzzling with
- What gets recorded in checkpoint files and could number of selects impact size of checkpoint file
- How are checkpoint files managed? How and when they get cleaned up
Below are few other details in regards to environment this is happening on
- SQL server 2016(SP1) 13.0.4001.0
- DB compatibility level 120
- DB recovery model - Full
- Weekly full, Daily diff and every 30 min log backups
- Checkpoint file of 128 MB is generated almost every minute.
Thanks
