“If I have seen further, it is by standing on the shoulders of giants.” Those words are attributed to Issac Newton and they are fitting for the way I was feeling recently as I thought back to those who have helped me in my career. While we might always want things to be better, as technologies we have it pretty good. There are unnumbered people who have dedicated untold amounts of time so we can have the tech available to us. We take a moment to think about those who have paved the way for us to be where we are now.
Whose shoulders are you standing on? Let us know in the comments below.
“This idea that the way he was able to look at the world is based on all the previous work that has been done”
“I guess “gratitude” is the right word of those who have gone before us and enable us to have those who are in technology we have a pretty nice career.”
“There are just a lot of people out there who just want to help and just want to better things with what they do every day.”

Transcription: How do you start consulting?
Carlos: Companeros, welcome to Episode 113. It’s good to have you on the SQL trail again.
Steve: Yes, it’s good to have everyone who’s listening. Good to see too, Carlos.
Carlos: Yes, always good to connect back with you, Steve. Today, we’re going to be talking about, kind of changing the subject up a little bit, and the idea is standing on the shoulders of giants. We’ll get it to more what we mean about that in a bit later but that’s the idea of our topic for today.
Steve: Ok, sounds good.
Carlos: So we do have a companero shout out. I want to give a shout out to David Stokes. Now as we record this we actually have not had the Companero Conference just yet. That will happen, actually as soon as I hang up I’m going head down there and have the conference. But I want to give a shout out to David. David is the leader of the Norfolk user group. He was actually the first person to buy a companero ticket and has been a great supporter of the podcast and of the conference. I want to give a shout out to him and thank him for what he’s done.
Steve: Yup, you know the interesting thing about David is that he is the very first user of Database Health Monitor that I have ever met in person.
Carlos: Oh ok, interesting
Steve: I met him at Charlotte, North Carolina for PASS Summit, was that 3 or 4 years ago?
Carlos: That’s right, 2013 I believe
Steve: 2013, ok, so 4 years ago. Yeah, it was really kind of cool to meet him and listen to what he had to say about Database Health Monitor back then and he’s been using it ever since. David is a friend of Database Health Monitor.
Carlos: Yes, very nice. Ok, as mentioned, I’m sure the conference went great. You already have that and we’re looking back to some feedback. We will probably have some kind of post mortem about that. But now I think it’s time for a little SQL Server in the News. We’ve been going back and forth a little bit about this and one of the things I wanted to talk with, of course we know that SQL Server 2017 is out and should be up, right? I’m sure you spent your weekend installing that. But one of the things that I wanted to discuss a little bit here which has been mentioned I think it’s expanded a little bit here and that is the interleaved execution for multi-statement table valued functions.
Steve: Oh yeah, this sounds pretty cool because there’s been so many concerns over the behavior of multi-statement table valued functions over time.
Carlos: That’s right. Yeah, so ultimately the bad news is that in previous versions of SQL Server, and I guess in 2017 as well. I mean, there is a fix for it but the optimizer can’t always determine how many rows the table valued function is going to affect. As a hard time just in for that fact, right, and so in previous versions basically it would guess a hundred and then it would really be 5,000 and so we have a bad plan, and that was kind of the issue. So what they are going to do here with 2017, they are adding some analytics and some machine learning basically into the optimizer, so that when the first time the plan comes in with the table valued function it’s going to guess again a hundred rows when it executes it’s going to have 5,000 rows. The difference now is that the second time it runs it’s going to take a peek at that previous plan and say, “Hey, how did I do?” And it says, “Oh, I did horrible. Let me adjust my numbers and take in the previous execution into account to see if I can come up with something better.”
Steve: You know, I wonder as I hear that if that is actually going to help or hurt because. I mean, if you table valued functions commonly have the same number of rows they are processing it might help you. But what happens if you’ve got such a wide variety of data in your database that every time that gets called the table valued function has a very different set of data that it’s processing depending on a client or customer or whatever it may be.
Carlos: Right. Yeah, and so obviously we have skewed data it makes it difficult to solve for the outliers. There still probably an outlier case. I think here what they are trying to get at basically is do I use a hash or do I use nested loops? Which way that I’m going to go about that? I think, again, after you execute it a hundred times you’re going to have some data there to then be able to say, “Ok, well, 80/20 rule. This is the way I’m going to go with.” I guess the implications here are not suggesting all of a sudden that everyone start using table valued functions and this is going to solve everyone’s problems there. I guess what was curious, or what was interesting to me is that I thought this was a very interesting way because we hear a lot about artificial intelligence, analytics, machine learning even. This is now a problem that we deal with all the time and now Microsoft is putting that analytics, that machine learning into the product that we love. And I thought, you know what, I meant that’s kind of a very specific scenario. I wonder if we couldn’t start taking some of the same thought and then applying it to other areas of our business so that our users or our customers might also benefit, so that was kind of my thinking there
Steve: Right, so it will really be interesting to see if somebody comes out with like an AI package for tuning SQL.
Carlos: Yeah, something like that, right. Or even that idea of, “Ok, I have this data. My customers keep asking me for whatever use cases. Can I apply some analytics here to give that better information? So it will be interesting to see how this continues to evolve. I think this idea is going to affect those of us who continue to be administrators or gatekeepers of data. These are going to be problems that we’re going to have to start solving, so it will be interesting to see how other tools crop up and try to address other problems.
Steve: Yup. Yeah, and I think it’s been easier with just sort of fix rule sets previously to be able to definitively say this is how something behaves. But with AI built in on how those things are being handled and how it’s tuning itself almost, it may be harder or maybe more work to figure out exactly what’s going on when there is a problem
Carlos: Sure, and I think that’s goes back to you are still going to have to know your system for those outlier cases. What’s going on? Why are you doing what you’re doing and is there a different way to potentially go about it?
Steve: Yup, interesting.
Carlos: Ok, so today’s episode, the show notes are available at sqldatapartners.com/giant
Steve: Or at sqldatapartners.com/113 for our episode number.
Carlos: Yeah, so ultimately this idea, and maybe a became a bit nostalgic which we can get into in a second but Sir Isaac Newton is quoted in 1675 as saying, “If I have seen further it is by standing on the shoulders of giants.” And ultimately this idea that the way he was able to look at the world is based on all the previous work that has been done, right? Helping him to arrive to where he is now. I got a bit, as I mentioned, nostalgic about this idea where I ran into to somebody who work with a former co-worker of mine. We started talking, and so this former co-worker is actually the person who convinced me to apply for my first database job.
Steve: Oh, I remember that story from one of our previous podcast.
Carlos: Yes, and I wasn’t actually completely qualified for it. But he convinced me and he coached me and said, “Hey, I think you do great.” And I think back to that, obviously, you know, there are thousand different I could have gone but I think about where I am now and ultimately kind of that first step of making that decision. And so I think about it, I guess “gratitude” is the right word of those who have gone before us and enable us to have those who are in technology we have a pretty nice career. Yes, it’s not all roses and sunshine all the time but the fact that those giants have gone before us, many of whom we’ll probably never know. We have to look up in Wikipedia, and the fact, even the first people who put together the rules for the transactional database. I know he was brought up in a keynote, unfortunately I can’t remember his name, obviously on top of my head. But, I mean, they put in place what we have today. And I think it’s easy, and not to discount. I don’t mean to discount them at all but it’s easy to look at the Bill Gates, and the Steve Jobs, and the, what is it? Oh gosh, Linux is going to kill me now
Steve: Linus Trovalds.
Carlos: There you go, thank you.
Steve: I don’t know if I pronounced that right
Carlos: If not, I’m sure you’ll get corrected. Again, not to discount their contributions but they are not the only ones. You think about all the teams behind them that helped them do what they wanted to do.
Steve: Yeah, I guess with that, I mean you look at a product like SQL Server, it’s really been like a Microsoft product since 1989/1990 but it was being worked on for years before that and then before anybody even started working on what became SQL Server, there were people in the 70’s that were theorizing on how these databases would work and the rules around it. I mean, 50 years worth of work, and foundation that has gone into what we have today in SQL Server 2017
Carlos: Right, and how amazing it is. It was interesting to kind of [term unclear – 11:26] here slightly. I was watching a documentary on bitcoin, and so bitcoin is the digital currency that they are trying to advance and I didn’t realize but, oh gosh, this Swedish guy who started Wikileaks. Whatever his name was, he was part of the original group of this eight people who put together sort of theorizing about digital currency, and they came up with a block chain idea and methodology. It was because of his situation and what Wikileaks was doing that really kind of put bitcoin on the map because when PayPal took their services away and said, “Hey we’re not going to let you use PayPal services.” That’s when he was like, “Ok, well, bitcoin, Internet can you help me,” and kind of launch that whole idea. In a way it was very interesting. But anyway, in the documentary they go and they talk about and they say, “The person through the door with a new idea get shot.” Anytime you have something revolutionary, the first person through get shot but somebody has to go through the door. So they talked about some of these first people like the first companies that started in New York City trying to exchange currency. For example, dollars to bitcoin and things like that. Well, he’s going to jail. Long story, but you can watch the documentary. Anyway, but I thought it was interesting. I guess going back to this idea that all of the ground work that was put in to enable us to enjoy what it is that we enjoyed today.
Steve: Right. But what was interesting, I mean, he was going to jail for Wikileaks side of things not for bitcoin side of it.
Carlos: Yeah, I’m sorry, so Julian Assange. That’s his name, the Wikileaks guy, and he is going to jail for something else. I don’t know it. But the guy in New York City who was doing the bitcoin exchange, so he was actually trying to get people on the bitcoin and basically sell them, bitcoins this idea. He is going to jail because one of the guys, unfortunately, illegal activity tends to push a lot of innovation. And so when you have something that is not monitored there was some illegal activity going on. He knew about it, and he was basically selling bitcoin to people who were doing illegal things and so that’s why he’s going into jail.
Steve: Oh, interesting. Ok
Carlos: It wasn’t that he was doing anything illegal but he was kind of aiding, and abetting if you will in a sense.
Steve: Wow! I hope I’m not considered aiding and abetting by investing in bitcoin. Or maybe the word is “gambling” not “investing”
Carlos: Yeah, that’s right. It is still a bit shaky, again to progress for a minute, the value of how that gone up it was pretty impressive but obviously it has come down I think in 2011 or 2013 something like that. And so where I was going a bit with this as well is this idea of it kind of grits on my nerves a bit, and we all like to complain. We all find ourselves in situations we don’t want to be. When people will say, “Gosh, I they had only done this right. Why they have to do it this way?” Basically, I’m inconvenience and I don’t really appreciate all the things that I have
Steve: Right, and sometimes that inconvenience comes from just not understanding what the people did before you and just complaining about it. I mean, I’ve done that but I’ve seen that happen plenty of times.
Carlos: Yeah, that’s right. You have that “Aha” moment where you’re like, “Oh, so that’s how it works.” Sure, you may have developed it differently; you may have architected it differently all of that jazz, great. But, you know, you work there, right? And now you’re now kind of taking advantage or taking over in some case. No I’m not saying it’s all always great but the decisions that were made there before you have you put you in a position where you can now either take over or ride that bus if you will. Yeah, it’s kind of interesting.
Steve: Yup, and you may look at something and say, “Wow, that’s stupid. Why would they have ever done that?” But then you look back 10 years ago at what was being done, or 15 years ago, and that was cutting edge technology and the fact that it even worked at all was completely brilliant.
Carlos: Exactly, exactly. Yeah, you know it is funny particularly as database people, like yourself Steve, there are developers among us or recovering developers or whatever you want to call them. But we like to complain quite a bit about you know, and the stupid developer if you’d only done that. Well, I can kind of find that we’re being a bit of a hypocrite because we use software all the time, on our phones and on our computers. I mean, we wouldn’t be able to do anything that we do now if it weren’t for software. We need to be mindful of where we are, what has been invested and give people a little bit of break when they are not upgrading to the latest thing. I guess in our last episode even was about patching. You know, just staying up and keeping with the latest and can kind of get a little tiring sometimes, and so you’ll forgive people a little bit if they are not quite there to where you are.
Steve: I think some of that comes back to what I learned in a class. It was called the Dale Carnegie class that I took several years ago. It was based on “How to Win Friends and Influence People” book as well as some other books, and it was a simple statement that said, “Don’t criticize, condemn, or complain.” It’s just that one of those things that just comes up and if I find myself criticizing, condemning or complaining, I try and stop myself. I try, so it doesn’t always happen but I try.
Carlos: Yeah, it’s one of those things, the reality in today’s world with social media everybody has a voice box or a [term unclear – 18:11] and they want to get up. It’s not to say that reform is not needed, that we can’t make progress. There are times when change needs to happen. There’s no question on my mind. I think it is just more about the way that we go about it and then recognizing what we have and how do we go from there.
Steve: Yup, and you know, no matter how bad the day may be we’ve got things pretty good right now. I think that’s so often overlooked in, well you mentioned social media, I mean, if you’re on social media and it’s almost like everyone is out there just to complain
Carlos: They are either having the best day of their life at the beach with the vacation photos or the world is against me. I think those for you companeros, those who are listening, going to be in technology, yes, you may not be where you want to be. And I’m not saying that you should settle. That’s not what we are saying either but I do thing that you if you take a minute to use the phrase from our culture if you will, is to capture many blessings and just to kind of appreciate where you are and know that there is a path ahead. If you will continue to work there, like we talk about in the beginning, all these artificial intelligence and analytics; yes, is it going to affect you, is it going to change what you do? Absolutely, but hopefully that will be to your advantage and not to your decrement.
Steve: Right, yup
Carlos: Anyway, we thought we change us up just a little bit and share some of our thoughts on that topic. I guess we’d like to, again, thanks to all those shoulders we stand on, so Robert Pollard, he was the guy who commits me to get to that job interview. I even think about Matan Yungman and Guy Glanster. The other guy is the SQL Server Radio. They are out there doing the podcast. Listening to them made me think, yeah, let me try this. Right, let me do this as well. And then of course all those in the community who have give freely of their time. I guess especially thinking about that to all of the speakers who came to the Companero Conference. They put a lot of time and energy and I’m super appreciative to them and what they’ve given.
Steve: And you know, it’s just interesting because one of the reasons that I enjoy what I do so much I think a big part of that is because of the SQL Community. You don’t see, at least I have never seen a tech community similar to what we have with the SQL Community. There are just a lot of people out there who just want to help and just want to better things with what they do every day. And I think that’s awesome
Carlos: Yeah, that’s one of those things. I think standing on the shoulders, again, I’m sure there will be a lot of people out but I kind of, if there’s one person I would point to, Steve Jones. So Steve Jones, probably one of the most humble guys you’ll ever know. He has done quite a bit in the community, kind of a very public figure but he is always looking to help and do so in a way that he’s not boastful. He is just trying to help you along and he has taken his breathe of experience and freely gives of that and all things to do this.
Steve: Yup, and what’s interesting with Steve Jones is that when he presents and gives back and shares with people. He does a great job in the tech side but he also does a great job on like the personal improvement side. Like, how do you get out there and improve the position you’re in – how do you improve your social media footprint, how do you improve your value, all those kind of things. I’ve seen him present a few times and definitely another giant to call out there.
Carlos: Yeah, it was funny, so we have him on the podcast that was one of those first ten episodes and looking to expand your game. And one of the things that I really liked about Steve, because again, he is one of these internet famous folks and he is also one of the few of that genre that will come up to you and say, “Hey, I’m Steve, what’s your name?” You’re like, “Ahhh. I forgot, I know who you are.” Of course he is in a Hawaiian shirt. He has a great brand but part of that brand I feel like is his contribution, and because of that he has made it the norm or almost the expectation of this is what the community does.
Steve: Right, yup.
Carlos: So awesome, so that’s our episode for today. Companeros, thanks as always for tuning in. Our music for SQL Server in the News is by Mansardian used under creative comments. If there is other topics you would like for us to talk about or ideas, you can hit us up on social media. I am carloslchacon.
Steve: You can connect with me on LinkedIn stevestedman, and we’ll see you on the SQL trail.
