Another option is to place these files in /etc/ssl/private and create a soft link to them in /var/lib/postgresql/<version>/main/ like so: ln -s /etc/ssl/private/your_cert.key /var/lib/postgresql/<version>/main/server.key ln -s /etc/ssl/private/your_cert.crt /var/lib/postgresql...
Now, by using theorder()function you can sort the data frame first by ascending order on thepricecolumn and then descending order on theidcolumn. To sort the column in descending order, prefix the sorting variable with a minus sign.
The range symbol “`-`” is the only “minus” character normally available on keyboard. Its ASCII code is~45. It must not be any special character that somehow resembles a horizontal dash. The order of printed notes on the same verse corresponds to the order of the phrases on which ...
