restore not working when path contains folder starting with a dot

Hi, i'm facing an issue with sql server 2017 express. 

when restoring a database from a path that contains a folder starting with a dot, sql server states that it cannot find the file.


this path works: 

E:\Gitlab\Runner\builds\484fdf65\0\ci\db.bak

but this path could not find the file: 

E:\Gitlab\Runner\builds\484fdf65\0\.ci\db.bak


it's not a permission issue, the folder it's the same (renamed).

the exact message is: 

 Operating system error 3(The system cannot find the path specified.)

Microsoft SQL Server 2017 (RTM) - 14.0.1000.169 (X64) express on windows server 2012 R2

is this a bug/limitation?

hi,

   is it by default off on 2012?

and I could not understand the following lines meaning.

because the article says.

QO changes that are made to previous releases of SQL Server are enabled by default under the latest database compatibility level in a given product release, without trace flag 4199 enabled.

and the following table says that both are disabled.

https://docs.microsoft.com/en-us/sql/t-sql/database-console-commands/dbcc-traceon-trace-flags-transact-sql?view=sql-server-2017#4199

Index fragmentation - regular indexes vs. columnstore

Hi!

We have several nonclustered columnstore indexes in the database.

When we're checking index fragmentation in SSMS, clicking  on index -> rebuild, it shows high fragmentation - about 50% or even more.

However, query based on sys.dm_db_column_store_row_group_physical_stats, shows 0 fragmentation.

Which one should we believe?

Thanks,

Alex

*** Query for reference ****

SELECT i.object_id,   
    object_name(i.object_id) AS TableName,   
    i.name AS IndexName,   
    i.index_id,   
    i.type_desc,   
    CSRowGroups.*,  
    100*(ISNULL(deleted_rows,0))/total_rows AS 'Fragmentation'  
FROM sys.indexes AS i  
JOIN sys.dm_db_column_store_row_group_physical_stats AS CSRowGroups  
    ON i.object_id = CSRowGroups.object_id AND i.index_id = CSRowGroups.index_id   
WHERE object_name(i.object_id) in ( 'Fact_Invoice_lines')   
ORDER BY object_name(i.object_id), i.name, row_group_id;

Hi Experts,

Unable to connect from (A -Domain1) to other server with different domain(B-Domain2). I was using the SQL Authentication, however connection is successful from other server(C - Domain3) to server(B-Domain2).

Getting below error.

A connection was successfully established with the server, but then an error occurred during the pre-login handshake.(provider:TCP Provider, error: 0 - An existing connection was forcibly closed by remote host.)(Microsoft SQL Server. Error:10054).

TCP/IP and Named pipes are enabled.

Please let me know how to troubleshoot.

Executing SQL files through command line.

Good morning,

I would like to use a SQL Agent job step to execute sql files from a local directory. The service account that owns the job has sysadmin rights and has full rights to the directory. When I execute the following commands from a query window in SQLCMD mode, I get good results: 

:ON Error EXIT
:r "C:\Path\filename.sql"
GO
:r "C:\Path\filename.sql"
GO
:r "C:\Path\filename.sql"
GO

However, when I place the same code into a job step and run it under type Operating system (CmdExec), I get this error:

The process could not be created for step 1 of job  (reason: The system cannot find the file specified).  The step failed.

What am I missing here?

SQL server 2016 SP2 :

 The client was unable to reuse a session with SPID 215, which had been reset for connection pooling. The failure ID is 50. This error may have been caused by an earlier operation failing. Check the error logs for failed operations immediately before this error message

is this for connection exceeds? or authentication failure ?

what is the workaround?

Hello,

We are seeing errors in the SQL Server Error Log like the following:

Date  10/17/2010 11:12:10 PM
Log  SQL Server (Current - 10/18/2010 8:01:00 AM)

Message
Error: 18056, Severity: 20, State: 29.

Date  10/17/2010 11:12:10 PM
Log  SQL Server (Current - 10/18/2010 8:01:00 AM)

Source  spid401

Message
The client was unable to reuse a session with SPID 401, which had been reset for connection pooling. The failure ID is 29. This error may have been caused by an earlier operation failing. Check the error logs for failed operations immediately before this error message.

During this time our applications are unable to connect to SQL server and are systems expericnce a significant slow down.  Our applications report the following error in the Windows Event log during the same time the error messages are logged in SQL:

"System.Data.SqlClient.SqlException: A network-related or instance-specific error occurred while establishing a connection to SQL Server.  The server was not found or was not accessible. Verify that the instance name is correct ant that SQL Server is configured to allow remote connections.  (provider: TCP Provider, err: 0 - The wait operation timed out.)"

Resources on the SQL server do not seem to be constrained at all.  This is running on a Quad 6 core 64-bit server with 128GB of RAM.  There does not seem to be a patteren to when this occurs and things seem to correct themselves automatically until the next blip.  Other posts I've seen say to look and other errors right before this, but unfortunately there are not any other errors prior to this, it is the first error we see preceeding the problem.  Any help would be greatly appreciated.

Thanks,

Henry

sleeping processes and blocks.

hi all,

What are the circumstances a sleeping process can create a block. We had a scenario in Prod environment where i saw one process blocking the other process. I saw parent process was running some INSERT statements and last_batch column in sp_who2 was changing every second and status is still SLEEPING. I assume this means that session was INSERTING individual rows one after another. 

Is my analysis correct? question i still have is, if session is doing INSERT each second why status is "SLEEPING" i was expecting it to be either suspended or running.
