SSH connections from TSQL?

February 13, 2019, 4:27 am

Hi there,

I am currenly consuming MySQL remote servers allocated in AWS by using "link servers - odbc" approach from my Middleware SQL Server.

 

This is an example, from my stored procedure I call my link server this way:

 (NEW2 represents a Link Server name that uses an underlying mysql odbc driver) So far so good.

Set @SqlCommand=';WITH SRC AS(

                   SELECT * from OPENQUERY(NEW2,''SELECT s.invoice_no AS purchaseid

      , IFNULL(s.customer_id, ''''JP99999998'''') AS consumerid

                                                          

      , NULL AS membership_id

      , 0 AS isemployeesale

 

Now i would need to connect to other MySQL using Tcp/Ip over SSH

I can connect by using MySql workbench manually from my laptop. I am just wondering how to consume this connection from one of my stored procedures in the server....

Here you have the properties of my connection...

 

 

Any example about that would be greatly appreciated? My assumption is I need to use a SSH client at first.

 

Thanks a lot,

Return table name from DMVs?

Greetings.

I've been using the following query to return problematic queries for a long time now. However, I started a new gig and a coworker asked if there's a way to return the table name in the first column (OBJECT_NAME(st.objectid)).  I see how this would be an issue if multiple tables are returned in the Statement or Query columns, but even if there's only one table it constantly returns NULL. How do I return the table being queried in this column?

--Running processes
select OBJECT_NAME(st.objectid), er.session_id, er.start_time, er.status, er.command, er.database_id, sd.name,
er.wait_type, er.last_wait_type, er.wait_time,
er.wait_resource, er.cpu_time, er.reads, er.writes, er.logical_reads,
[Statement] = SUBSTRING (st.text, er.statement_start_offset/2,
 (CASE WHEN er.statement_end_offset = -1
        THEN LEN(CONVERT(NVARCHAR(MAX), st.text)) * 2
  ELSE er.statement_end_offset END -
                                er.statement_start_offset)/2),
st.text as Query, es.login_time, es.host_name, es.program_name, es.client_interface_name, es.login_name,
es.status, es.total_scheduled_time, es.total_elapsed_time, es.last_request_start_time, es.last_request_end_time--, qp.query_plan
--for backups and rollbacks, not queries
--,er.percent_complete, er.estimated_completion_time
from sys.dm_exec_requests er
join sys.dm_exec_Sessions es on er.session_id=es.session_id
left join sys.databases sd on er.database_id=sd.database_id
right join sys.dm_os_tasks ot on er.session_id=ot.session_id
CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS st 
--CROSS APPLY sys.dm_exec_query_plan(er.plan_handle) qp
order by er.cpu_time desc

Thanks in advance! ChrisRDBA

Suppose I want to design a table that contains many columns. (e.g. six or more)

Some of the columns are "bit" - NOT NULL data types. (could be two or more)

How do I write a check clause to check that if one of the bit data columns is 1 (True) then the others are 0 (False)

I am under this situation.

I have a app server APPSRVA, 2 DB server DBSRVA , DBSRVB

Link server is created at  DBSRVA to link to DBSRVB, and APPSRVA has a script bat to call a store procedure

in DBSRVA to execute query in DBSRVB.

The link server is tested ok by using management Studio install in APPSRVA, connect to DBSRVA , right click the link server and test ok.

The link server is using "be made using the login's current security context"

How ever when the script is execute , there is error Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.

To simulate this issue, I clear the Kerberos tickets in APPSRVA. The issue happen again.

and just after when I test the link server successfully , the script can successfully run.

anyone hit this issue before ?

Got a question regarding syncing up SQL Jobs in all the nodes of the Alwayson cluster. We have a 3-node Alwayson cluster. With 2 nodes in on data center & another node in our DR location. Sometimes new application SQL jobs will be added to the SQL Server. Whenever those SQL jobs gets added, we want to have a sync process in place where the jobs gets copied over from primary active node to the other secondary nodes of the AAG cluster. Can't find much info on that. Any ideas? Thanks

Hi All,

2 Week ago Few of the database are started randomly going to recovery pending state - I will bring it online. This started to happen with all the database and its became very annoying- when started to look what is the issue - on the error logs i can see

The system failed to flush data to the transaction log. Corruption may occur in VolumeId: H:, DeviceName: \Device\HarddiskVolume7. (The I/O device reported an I/O error.)--12:04 The system failed to flush data to the transaction log. Corruption may occur in VolumeId: G:, DeviceName: \Device\HarddiskVolume5. (The I/O device reported an I/O error.)--23:00

 Issue - Randomly the databases are going to recovery pending state on all the 3 disk and logs with issue on SQLServerLogMgr::LogWriter: Operating system error1117(The request could not be performed because of an I/O device error.) encountered. The operating system returned error1117(The request could not be performed because of an I/O device error.) to SQL Server during a read at offset 0x00000000002000 in file 'E:\Microsoft SQL Server\MSSQL12.INST01\MSSQL\Data\XXX_log.ldf'. Additional messages in the SQL Server error log and system event log may provide more detail. This is a severe system-level error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.

I did checkdb - No errors- the we created the 2 new disk and checked again we started to get this issue back.This morning we are getting issue
