| If your learning the basics of SQL, there comes a point in everyone's experience of SQL where the learning curve suddenly jumps a notch. For me this topic made me reminise back to when I was a kid and my dad was letting go of your saddle for the first time on your bike without stabilisers! Joins were my nemesis at the start, I was looking for all sorts of clever ways of how they worked and being very suspicious of them as when your back was turned they could stab you! The reality of joins is far from the nasty scarey point I made above, the point I am making is that doing joins for the first time will feel very artificial and will make you fear them as you have not done anything like this before. The video being presented to you here will explain the basic concepts of what joins are, what they are for and why we need them. With the basics covered I really want you to understand the power of them and in reality they are a cute pussy cat of an option not something to be scared of. So follow this video and hopefully you will be in charge of the joins not the other way round. This is one of many videos which can be seen at PCTeach.me. Come join the gang! |
