A quick-n-dirty SQL tuturial
Recently there was a request from IDSK – they wanted the accession register SQL report for their Rabindranath Tagore Grant collection books to be listed in a natural sort. Documents of this collection carry the prefix “RT” which is fine and dandy. The “problem” started after that. In their earlier legacy system (SOUL v1) when these books had been accessioned, they did not use an fixed uniform length accession no for this collection. For example, instead of RT00001, it was entered RT1, RT2 and so on. Further, their problem was compounded by another glitch. In several of these accession nos, there were spaces inserted between “RT” and the actual numerical part. When they migrated to Koha with L2C2 Technologies, these problems were carried over to the new system as data curation and correction was not part of the deliverables. Now, three years later, when reports were being asked for, these issues had come back to haunt them.
The RT collection has over 4000+ books and a manual fix was not feasible at this time. So using the
ORDER BY keyword in the report’s SQL like this:
ORDER BY LPAD(REPLACE(REPLACE(TRIM(items.barcode)," ",""),"RT",""), 10, ' ') ASC we at least managed to hide the problem and also got natural sorting to work. The first
REPLACE() took out any space in the accession no, and the second REPLACE() stripped off the “RT” prefix, leaving us with only the number. Finally using
LPAD() we zero prefixed the number so that each one was exactly 10 characters long. And we had our naturally sorted list of accession numbers in the report as we can see below.

Steps to set up public-key based login into a vagrant managed kohadevbox VM
What is kohadevbox?
As the README.md at https://gitlab.com/koha-community/kohadevbox says – “Create a development environment for the Koha ILS project. It uses Vagrant and Ansible to set up a VirtualBox.” Basically it automates the long and somewhat complex process of manually setting up a development system for #kohails.
From the website – PuTTY is an SSH and telnet client, developed originally by Simon Tatham for the Windows platform. PuTTY is open source software that is available with source code and is developed and supported by a group of volunteers. It is our go-to tool on Windows for accessing physical Koha boxes or VMs via SSH.
Vagrant sets up SSH service on the VM to use public-key authentication. Therefore our PuTTY instance needs to know the private key that Vagrant had setup inside the VM, in order to login into it. As many posts in Stackoverflow indicates, this is a point where many people get stuck. Usually they try with
%USERPROFILE%\.vagrant.d\insecure_private_key and that typically fails.
Steps for kohadevbox
Using git-bash go to the directory where you had cloned kohadevbox. Be default it will be
%USERPROFILE%/git/kohadevbox if you have simply followed the instructions from kohadevbox README.md file. In our case, it was
%USERPROFILE%/gitdev/kohadevbox as we had changed it.
Run the command
You should see something like this:
The line to note in the output is IdentityFile. That’s the private key you need to grab and feed to PuTTYGen for it to convert it into a PuTTY compatible .ppk format private key.
NOTE: This path to the key is going to be different for different users, so do not attempt to copy-paste what you see here, instead use your own IdentityFile value.
Now we convert the
vagrant_private_key from IdentityFile and save it as a .ppk file.
And lastly we import it into PuTTY like this and we are good to go!
Finally we are logged in into the VM
NOTES: The versions of software used – (a) PuTTY.exe – 0.71 (b) Vagrant – 2.2.7 (c) Git Bash – 2.25.0 (d) VirtualBox – 6.1.2
