DBeaver and Nettezza - netezza

I am trying to use DBeaver for Netezza. My driver is the same as the one I am using for DBvisualizer.
When I run a query, I get NullPointerException for all Timestamp and Date columns. The same query runs in DBvisualizer perfectly.
Does anyone know why?
(my machine is a Mac OS)

Pass Through Query Generates "Invalid Cursor State" Error When Computer Upgraded To Windows 10

Users in my office who have been upgraded to Windows 10 (build 1909) are suddenly getting the message "[Microsoft][ODBC Drive Manager] Invalid cursor state (#0)" whenever they run a pass through query in Microsoft Access. It doesn't matter how complicated the Pass Through query is, they all crash. We use SQL Server on our back-end. I have tried updating the ODBC drivers on our users' machines to the most recent version, but this doesn't solve the problem.
It is very frustrating because I can open tables linked to our SQL Server with no problem. I can write an equivalent query in Access and it will run. I even installed SQL Management Studio on one user's machine, and I could run the query fine there, I just cannot get the Pass Through to run. We are using 32 bit Access from Office 365 with the most recent updates.
Any help would be appreciated.

SQL Server Remote Connection on Centos 7 Increddibly slow

I have an instance of SQL Server running on a Centos 7 VPS together with an application running on .net core 2.2.
I tried running the application on a separate VPS instance remotely connecting to the SQL Server VPS. But the queries where running really really slow. Like 100-500 times as slow to be precise.
I've also noticed that as of recently (it didn't use to) MSSMS also hangs for a bit each time I right click anything in the Object Explorer.
The connection string looks like the following:
Server=(IP of the VPS running SQL Server);Database=master;User Id=(username); Password=(password);
Any suggestions on what to do?
I figured out that the issue was resolved by using servers geographically closer to each other.

SQL Server (2012, 2014, 2017) query to figure out host OS

I'm trying to figure out what query will get the host OS, whether if it's a Linux or Windows OS.
Querying sys.dm_os_host_info seems to get the results I need but that table doesn't seem to exist on SQL Server < 2017.

Trying to connect to an Oracle server v9.2.0.8 with the pycharm database tool

I'm trying to use the PyCharm database tool to look at a couple of Oracle databases. The first database is an Oracle 11 database and connects with no problems. The second database, however, is an Oracle 9i database and is giving me issues. When i try to connect to it I get an error message that says
Unsupported combination of server/driver versions: found Oracle server version 9.2.0.8 with JDBC driver version 12.1.0.2 that is not compatible. Oracle server version 9.x must be connected by JDBC driver versions 9.x to 11.x..
I've tried finding where pycharm keeps the JDBC drivers but have had no luck. If someone could point me in the right direction I would be very grateful. I would also appreciate it if someone could point me towards where I can download drivers that will work with the Oracle 9i and 11(g i think?) databases.
I'm on windows 10 64 bit and using PyCharm 2016.2.3.
I have been using Oracle Server 9i- 9.2.0.4.
To query on this server I am using Jet Brains DataGrip.
It showed me the same error and then I changed driver jar of ojdbc6-x.x.x with
ojdbc14-9.2.0.1.jar and then It started working fine on DataGrip.
Hope this will be helpful.
Download ojdbc14-9.2.01 and configure it on your local Database management tool.

developing Microsoft Sql locally on mac

I've got a project where I have to work with Microsoft SQL which is new for me.
I already made a lot with MySQL server and database. Is there a way to developpe on a Mac OSX with a local MS SQL database and XAMPP or something like that?
SQL Server's database engine only runs on Windows. You can find a spare Windows box to run it, or host the machine with VMWare Fusion / Parallels.
Oracle SQL Developer can serve as a replacement for SSMS on Mac.
