sql server – Calculating percentiles of a FROM command

I have a query which generates a table of trials and values from a database (example pic below)

SELECT * FROM (ReMetrica).(ReMetrica_Result).(GetTrialValuesAsDouble) ('BD5E92F3-3A3B-43B4-BC22-409F34CE5980', 'Total', 'Net Loss', 1)

which is an expression we’ve been given with this bit of software.

enter image description here

I can calculate the mean of all these trials by using:

SELECT avg(Value) FROM (ReMetrica).(ReMetrica_Result).(GetTrialValuesAsDouble) ('BD5E92F3-3A3B-43B4-BC22-409F34CE5980', 'Total', 'Net Loss', 1)

However I’m trying to extend this to calculating percentiles as well with

SELECT percentile_cont(Value) OVER (ReMetrica).(ReMetrica_Result).(GetTrialValuesAsDouble) ('BD5E92F3-3A3B-43B4-BC22-409F34CE5980', 'Total', 'Net Loss', 1)

which doesn’t work due to an ‘incorrect’ syntax after OVER. Could someone help me with where I’m going wrong?

centos7 – Server is down after changing machine type in Google Cloud Platform

I changed my machine type(GCP) by stopping the instance, after increasing the machine type I restarted the instance and now server stopped working, the website is down now.
Upgraded from 1 vCPU, 1.7 GB memory to 2 vCPU, 4GB memory.
And if I select other than 1 vCPU, 1.7 GB memory, the webserver doesn’t respond.
Also, I can’t access SSH from a web browser it gives me an error that “Connection Failed. We are unable to connect to the VM on port 22.”

files – How to move a Drupal 8 site to a new server?

I have a Drupal 8 site on an Ubuntu 18.04 server and want to move my site to a new server with Ubuntu 20.04.

With Drupal 7 I did these steps

Create a set of keys (on the new server) :

$ sudo ssh-keygen -t rsa -b 4096 -C root@www-example-com
$ sudo cat /root/.ssh/id_rsa.pub

Add the public key (on the old server) :

$ sudo nano /root/.ssh/authorized_keys

Export the database (on the old server) :

mysqldump -u root -p www_example_com > /var/www/www-example-com/share/www-example-com_$(date +%F).sql

Repatriate the site file (on the new server) :

$ sudo scp -r -p root@xxx.xx.xxx.xx:/var/www/www-example-com/ /var/www/www-example-com/

Import the database (on the new server) :

mysql -u root -p www_example_com < /var/www/www-example-com/share/www-example-com_2020-08-10.sql

That’s all, with these intructions, the Drupal 7 site works.

The problem

Now with Drupal 8 there is Composer with a new folder and file tree present in the var directories and in home.
