SQL Job keeps running (no error)
Hello,
I hope all of you are well and safe
I have a SQL JOB with 10 steps (the step #4 is an update for zero or some rows (one column), the step #5 is a SSIS package to export some rows to a CSV). Since last week the step #4 stays running forever and more or less on the same times (8AM & 4PM). I restart the SQL Server Agent, gives an error and start working again until the next time (7:00 or 16:00hrs). I verified if there is a lock and there isn't and checkdb and is all ok. What can be happening? Need some advise because I don't know what else could be the reason. Many thanks in advance.

when there are no updates occurring, is it impossible for nolock to deadlock or return incorrect info?
hi we are migrating to 2019 enterprise. i am a big fan of rcsi.
im anticipating a debate from my peers that goes like this..."our users do reads only during the window of time that updates to the db aren't occurring. so whats the problem with continuing to use nolock and forgetting about rcsi?"
in such a scenario is it possible to get incorrect data while reading in the window?
I think deadlocks and blocking would still be possible.

Manually updating statistics fixing the slowness
I have a table around 8 Million rows and daily night it has a scheduled maintainence plan which takes care of Index & statistics update ( by Index optimize script by ola hallengren) . From past few days slowness is observed for a SP which has this table and if i execute update statistics manually on this table then the SP will run fast.
Note :
There will be around 20K insert/updates on table daily.
The table has only 3 columns with Int data type's and a primary key clustered index on a column.
The instance is hosted on SQL Server 2016 version .
My question : Eventhough running index maintainence and only 20K insert/updates happening daily why updating statistics manually will fix the slowness issue.

Link Server to PostgreSQL from SSMS throwing an Error
Hi All,
I am trying to connect a link server from SQL Server DB to PostgreSQL DB. I have SQL Server 2012 Version.
I have configured ODBC Driver and it is working fine. I tested this using SSIS and I am able to connect to PostgreSQL from my Local Computer and can see tables in SSIS ODBC Source.
But when I try to create a link Server getting error message:
On Prod server Getting error Message:"
Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "POSTGRESQL".OLE DB provider "MSDASQL" for linked server "POSTGRESQL" returned message "[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified". (Microsoft SQL Server, Error: 7303)

Using FOR SYSTEM_TIME clause with views over temporal tables in stored procedure creation
Hi,
I'm getting the following error message when creating a stored procedure that contains a query that references a view that references a temporal table:
Message 13544... Temporal FOR SYSTEM_TIME clause can only be used with system-versioned tables. 'db.schema.table' is not a system-versioned table.
If I run the query outside the scope of the procedure creation, the error does not occur.
The table is for sure a temporal table, and there is usually no problems including a FOR SYSTEM_TIME when querying views that reference temporal tables.
What do I have to do to get around the error?

are order by ordinalss really illegal in 2019 procs, funcs, views and triggers?
hi im seeing this from a tool run run by our dba regarding a warehouse upgrade from 2014 to 2019.
Is this just a warning having to do with coding style or a real "showstopper"?
If it is a "showstopper", how will embedded t-sql in pkgs and perhaps reports be impacted?
I believe our dba will be making the new server "2015 compatible".
This rule checks stored procedures, functions, views and triggers for use of ORDER BY clause specifying ordinal column numbers as sort columns. A sort column can be specified as a nonnegative integer representing the position
of the name or alias in the select list, but this is not recommended. An integer cannot be specified when the order_by_expression appears in a ranking function. A sort column can include an expression, but when the database is in SQL 90 compatibility mode
or higher, the expression cannot resolve to a constant.

Unable to kill a session with MSQL_XP wait type in SQL Server
I had a sql query provided by App Team that was ran 3 days ago which included a mail to be sent using sp_send_dbmail. However, i see that the sessions are still present and unable to kill the session as it still shows "killed/rollback" state.
The SPID's are in MSQL_XP wait type. I digged into it further and found the extended stored procedure "xp_sysmail_format_query" being used. However, since i do not have access to process explorer to be ran on production server, could you please help me in getting these sessions killed. Please note i cannot restart SQL server or agent services as its production server..

FILESTREAM: failed to connect to kernel driver RsFx0502
Environment is SQL Server 2017. The problem occurs on different installations.
I describe one of the cases that im investigating:
On a Windows Server are 5 SQL Server Instances installed. All 5 SQL Server instances are configured to use SQL Server Filestreams. The Startup of all 5 Services for the SQL Server Instances are configured on "Automatic"
Usually, when the Windows Server is restarted, for example after Servicepack Installation, all 5 SQL Server Instances start without any problem. SQL Server Log Message: "FILESTREAM: connected to kernel driver RsFx0502. This is an informational message. No user action is required." Everything is alright.
But in some cases, after a restart ob the Windows Server, 2 of the SQL Server Instances can initialize the FileStreams. But the other 3 SQL Server Instances fail to initialize the Filestream Features:
Error Message:
FILESTREAM: failed to connect to kernel driver RsFx0502.
<{1038F43D-3391-45F7-B1B3-BADF26459429}>Failed to initialize CFsaShareFilter: Error 0x80070015 (-2147024875)
I can manually restart the 3 SQL Server Instances, and the FileStream Features get initialized.
Just my guess, is there a timing Problem with the Filestream Feature an the SQL Server Instance Start?
Is it possible to configure a dependency on the Service Start of the SQL Server Instance to wait for the Filestream Services?
My other thought was to configure all SQL Server Instance Services to manual and start the SQL Server Services with the Windows Scheduler using a PowerShell script to delay/time the start of the 5 SQL Server instances and their related Services.
Any advice, suggestion or fix for the problem?
Best regards
Paolo

signing clr assemblies for 2019 migration
Hi, i'm showing the clr warnings from the migration assistant regarding our migration from 2014 to 2019.
can someone explain at a high level what mitigating this entails and why? is it safe to say that at the time the warning was issued the target 2019 "instance" didnt have one or both of the 2 more vulnerable alternatives set? is there an easy way to see what those settings are on the source right now?
basically we have 2 assemblies, 3 if you count one that seems to have no dependencies. clrroutines ->fn_splitstringsclr-> 23 procs. clrutilities->fn_splitlongstringclr->15 procs. microsoft.sqlserver.types->no dependencies.
Assembly '[CLRRoutines]' with PERMISSION_SET = 'Safe' cannot be migrated. For more details, please see: Line 1, Column 1.<p>When CLR Strict Security is enabled, attempting to create an unsigned assembly will cause an error. Use the following steps to create a signed assembly: </p><ol><li>Create a key pair file. For more information, see How to: Create a Public-Private Key Pair.</li><li>Compile the module and sign it using the key file. For more information, see How to: Sign an Assembly with a Strong Name.</li><li>Create an asymmetric key in the master database from the key file CREATE ASYMMETRIC KEY MyStrongNameKey FROM FILE = 'C:\MyStrongNameKey.snk'</li><li>Create a login from the asymmetric key CREATE LOGIN MyStrongNameKeyLogin FROM ASYMMETRIC KEY MyStrongNameKey</li><li>Grant UNSAFE ASSEMBLY permission to the login GRANT UNSAFE ASSEMBLY TO MyStrongNameKeyLogin</li><li>Now users with CREATE ASSEMBLY permissions can create assemblies signed by the key</li></ol> We recommend signing assemblies by following the steps outlined above. However, you can alternatively do one of the following: <ul><li>Set the Trustworthy Property of the database to ON and grant UNSAFE ASSEMBLY permission to the login that owns the database. This is not recommended because marking a database as Trustworthy can allow malicious assemblies to impact resources outside the database. For more information, see Guidelines for using the TRUSTWORTHY database setting in SQL Server. </li><li>Disable CLR Strict Security by using sp_configure. This is not recommended because assemblies marked SAFE or EXTERNAL_ACCESS may enable elevation of privilege from a database user to a sysadmin. sp_configure 'show advanced options', 1 GO sp_configure 'clr strict security', 0 GO RECONFIGURE GO</li></ol></p>
