We are getting the error as below:
Message
Executed as user: domain\DBAdmin. sqlmaint.exe failed. [SQLSTATE 42000] (Error 22029). The step failed.
The transactional logs are not deleting since Sept 2019. What is the best process of deleting the transactional logs? Can I create full backup, change the database recovery mode to simple, delete all transactional logs and run the job again.
All,
In PolyBase, can t we append data into the External Table (csv file as the source) with rows from T-SQL?
The below example seems to indicate so:
https://docs.microsoft.com/en-us/sql/relational-databases/polybase/polybase-configure-azure-blob-storage?view=sql-server-ver15#exporting-data
If this is true, then for every source that we need to append to should we also create another EXTERNAL table? The INSERT seems to be work on the newly created table.
Thanks,

Environment: SQL Server 2014 on Windows Server 2012 R2.
Our application uses hibernate and the jTDS JDBC driver, so we are (by default) getting generated SQL statements coming through as sp_prepare and sp_execute. Sometimes, I am able to find the prepared queries in the cache, but sometimes I'm not. By cache, I mean sys.dm_exec_query_stats and sys._dm_exec_cached_plans. What's strange is that even if they seem to be gone from the cache, the prepared statements execute successfully. I'm wondering if there is some other location where I could consistently see/find the prepared statements, hopefully by their integer handle?
Thank you,

When I query an External Table which has a datetime column why is it giving me an error even though I was able to enter data into it successfully? This table is pointing to Azure Blob Storage.
Msg 7320, Level 16, State 110, Line 28CREATE EXTERNAL TABLE dbo.wasbs_Claim
(
ID int,
Claim VARCHAR(128),
Claimdate datetime
)
WITH
(
LOCATION = '/claim/', -- see below comment
DATA_SOURCE = csvsource,
FILE_FORMAT = csvformat
)
GO
insert into dbo.wasbs_Claim(ID,Claim,Claimdate) Values (1,'Automobile','01/06/2010') -- Will fail
GO
select * from dbo.wasbs_ClaimThe below T-SQL query goes through though:
DECLARE @stringdate nvarchar(100) SET @stringdate = '2020-01-06 00:00:00.000' DECLARE @datetime datetime SET @datetime = @stringdate PRINT @datetime PRINT @stringdate
Hi,
I am new to the SQL coding. Need help in configuring the mirroring alert when the db will go to suspect mode.
I configured dbmailprofile and succesfully i am able to send the mail through sql server .
now for alert i given the below step in job.
exec msdb.dbo.sp_send_dbmail
@profile_name='newprofile1',
@recipients='abc@xyz.com',
@query='select name,state_desc from sys.databases where state in (0,1,2,3,4,5,6)'
@subject='db status alert',
@body='status of the db'
I required the code in such a way that alert should generate when ever the database will go to suspect mode.
As of now i configured in such a way that its throwing mail with current db status.
But need mail only when db will go to suspect mode.
i configured the job schedule for every 15 min. instead of giving mail for every 15 min , i should get mail only database will go to suspect mode.
Please help me to modify the code. Its little urgent.
Thanks,
Jo

I have a scenarios whereby a checkdb on an 800GB database was cancelled and 3 days later, there is sessions stuck in "killed/rollback" state.
I ran
select blocking_session_id, wait_time,wait_type, last_wait_type, open_transaction_count, percent_complete,estimated_completion_time, cpu_time,total_elapsed_time, reads, writes, granted_query_memory, parallel_worker_count
FROM SYS.DM_EXEC_REQUESTS
where session_id in (66)
and i see the wait type is EXECSYNC, percent complete 10,05694 and doesnt change, estimated completion time is rising, cpu_time is not changing, reads and writes are not changing either.
I dont want to restart the Instance as i am afraid the database will go into recovery and it will take the same time to recover and users will not be able to access, for now, at least users can access but it is extremely slow.
Will it eventually complete? or its hung ?
Any advice ?

Dear,
We want to restore a ms sql database from full database backup and differential backup.
Please help to tell me how to confirm the time of restored database. Thanks!
I am having a requirement to send mail alerts when there is a blocking. And I am planning to use SQL alerts.
We have a counter called 'Processes Blocked'. Can it be used to capture blocking details? If so, what all information will it gather.
Also, I see an option alert is counter rises\equals to 'value'. What is the value here?
Is it the time a blocking remains or the count of blockings?
Please suggest if there are any better options.
We are almost running all our production systems in VM and almost all servers are 64 bit , currently we have an Windows Server 2012 R2 VM Server that runs with SQL2016 SP2 ENT Core based edition.
OLTP system with 32 virtual processor and 4 sockets we have 128GB RAM, now we are with vendor isolating performance issues and vendor is keen to know why we have set our SQL service account with lock pages in memory which is not an VM ware recommendation .
Since we have max server memory defined on the instance ( we use as an standard to allocate 75% to DB and 25% to OS) and on all 64 bit boxes regardless of Physical or VM we have this lock pages in memory set.
I am stressed to know if really on VM SQL Servers Lock pages in memory option should not have been set or since we have already set max server memory to 75% of servers memory we are good on this memory part or is there really an trade off so my application vendor compels to go with VM recommendation not to set LPIM
Thanks and Reagrds

All,
I tried to create an External Data Source against another SQLServer (2016) from a SQLServer 2019 server but I get the below error:
<<External access operation failed because the location URI is invalid. Revise the URI and try again.>>
NYCSQL10.nydomain.net is a SQLServer 2016 server
Configure PolyBase to access external data in SQL Server
What am I missing?
Thanks,
CREATE EXTERNAL DATA SOURCE PolyBaseSQLHi,
Is my understanding correct that in SQL Server on Linux we will always get UTC time when running SELECT GetDate()?
Can't find any documentation related to this at all.
Thanks
I often see somebody use the Total Server Memory compare to Target Server Memory to decide whether the SQL Server under memory pressure. a book say:”Total and Target should be almost the same on a server with no memory pressure that has been running
for a while. If Total is significantly less than Target, then it’s likely that SQL Server cannot grow the buffer pool due to memory pressure”;
that is to say: if Total Server Memory <Target Server Memory ,it Represents Memory Pressure .
but I also see a article say:”
If the SQLServer:Memory Manager: Total Server Memory (KB) counter is more or equal than the SQLServer:Memory Manager: Target Server Memory (KB) counter, this indicates that SQL Server may be under memory pressure and could use access to more physical memory.”
that is to say: if Total Server Memory >= Target Server Memory ,it Represents Memory Pressure
So from those twomaterial:
if Total Server Memory <Target Server Memory ,it Represents Memory Pressure.
if Total Server Memor>=Target Server Memory ,it still Represents Memory Pressure.
That made me crazy,
So what's your opinion? thank you.
All,
The link shows how to create a format file using BCP. This assumes that the data is always extracted from a SQLServer table.
We receive lot of csv files from our business partners for which we cannot generate the format file and we plan to use them using OPENROWSET with the csv files being placed in Azure Blob Storage. Does anyone know how to generate the format file for a given csv file other than creating one manually?
In the below script, I manually created the format file currency.fmt for the csv data file currency.csv
Thanks,
