“If the challenge exists, so must the solution.”
– Rona Mlnarik
I like to use things in the way they weren’t intended. It leads to behaviors you weren’t expecting… and that’s pretty fun.
Often though, when you work for a software company, people want your solutions to do things they just were not designed to do, or have no capabilities to do at that exact point in time. The answer then that will often come back to you is a resounding: “I’m sorry, that’s not available at this time.” of course that is if you’re lucky enough to get an answer at all.
It’s no secret though, none of us who answer those questions like saying that. There is nothing worse than not being able to help people with what they’re trying to do.
Now don’t get me wrong – some people’s questions should be challenged. You cannot immediately assume that the person you’re talking to has all of the available variables, or has thought of any alternative means of achieving their end goal – which is why it is always important to ask ‘the why behind the why’. Every question has at least one immediate answer:
“I am going to buy a car.”
“Because I want to drive to work.”
This seems like a perfectly reasonable response. But what if we haven’t thought about every available option here? I can take this at face value and sell you a car, but i haven’t asked where you live and work; perhaps you live within the congestion zone in London where driving is impractical. Do you actually have off-street parking available? Will you need the car for other trips or just for work? With a little additional questioning and thinking we might establish that you live right near a London Underground station and it would be more cost effective and slightly faster to instead commute by Tube.
This is not just a sales tactic, rather one that should be used to better understand ever requirement, personal or professional – there is no substitute for good understanding.
But there are times when a perfectly reasonable request is made with good justification and unfortunately you’re still unable to help. But sometimes there are still ways to help, even if it doesn’t natively fall within the remit of the solution you’re working with. I had one such question recently:
“I would like to receive a list of Clones per image that have been created, which are older than 2 weeks and who created them, so I know which developers to nudge to refresh their Cloned environments and so we can create new images.”
Again this is a perfectly reasonable request, and the obvious answer was, well, “check the dashboard”, there’s a full list there with all of that information. When you have a good many developers all using SQL Clone though, it can get a little difficult to scroll through everything and identify the culprits. SQL Clone has no native alerting or reporting (as of writing) so it was assumed that was the best we could do.
Like I said though, I like to use things as they weren’t intended. Tee-hee.
When you install SQL Clone it creates a back-end SQLClone_Config database on an instance of your choosing (normally where you’ve installed the solution) for recording operations carried out within the software. This database is structured really, really logically that anyone can understand it and leverage it to meet their requirements.
By thinking a little more about their requirement we realized that it would actually be possible to leverage the database by running a very small snippet of T-SQL which could show us:
- The name of the Clone
- Who created it
- Which Image it belongs to
- When it was created and,
- How old it is
This was as straightforward as:
SELECT C.Name AS CloneName , C.CreatedBy AS CloneOwner , I.FriendlyName AS BelongsToImage , O.Timestamp AS CreatedOn , DATEDIFF(DAY, O.Timestamp, GETDATE()) AS AgeOfCloneInDays FROM dbo.Clones C LEFT JOIN dbo.Images I ON I.Id = C.ParentImageId LEFT JOIN dbo.Operations O ON I.Id = O.ImageId WHERE O.Type = 1 AND O.Timestamp < DATEADD(DAY, -14, GETDATE()) AND C.DeletedOn IS NULL;
This gave us exactly what we needed:
It was just that simple. But we didn’t want to leave it there! So we set up an email to be sent to the heads of each development team from a SQL Server Agent Job with the output of this query each Monday morning so they could raise it with the relevant members just after stand up. Now I had never done this before so of course who would come to my rescue but the wonderful, knowledgeable (and just all round awesome-sauce-person) Jes Schultz with this post from 2014!
And with that – we used something that isn’t exactly supposed to be used in this way, but got something valuable up and running for their teams. It’s a simple answer, but it was quick, and it worked.
What’s a quick win you’ve had recently?
