Advanced SQL tutorial In my last post,I introduced SQL basic and intermediate topics.We walked through the topics with simple explanation based and syntax highlight lessons. It really is a great way to quickly introduce and talk out a concept.But if we are to really appreciate the SQL syntax and it's application in real world projects,we need to put all the topics first into a working environment and test out the code. We are coders right😏😏!!? It really won't make sense to Cruse a topic minus coding. All the advanced SQL topics will be practice based sequence.On finishing,we will build at least 2 web applications based on all SQL topics to create dynamic and data driven applications. Enjoy our first set. #sql #sqlsyntax #sqlunion #databasedevelooment (at Area 23 Lilongwe) https://www.instagram.com/p/B_qYL7Dh7Ox/?utm_medium=tumblr
