Well I have had a bit of an overwhelming SQL introduction in one of my recent deployments of a clients server. In the past we have never had to deal with it because the support staff for the product using it always maintained it. Well it went south with them and I had to figure it out as I went but it left me with the wild notion that I cannot depend on the support group to help. I need to learn SQL quite simply. I know its a vast amount of knowledge, best practices etc and there are a ton of paid options for training on this. What I need is a tool set or site or DIY learning method of learning the basics of SQL, how to administer it and maintain it from a introduction standpoint. Does anyone have any suggestions for learning this or a good path to follow in picking it up?
I have used sites like Codeacademy in the past etc but even they have went to paid versions now. Looking for some get started info.
Thanks in advance!
