This course is designed to introduce advanced techniques of SAS programming using Structured Query Language (SQL). This course will help you to prepare for advanced SAS certification exams (SQL part). SQL stands for Structured Query Language. According to ANSI (American National Standards Institute), it is the standard language for relational database management systems.SQL is one of the many languages built into the SAS System. Using PROC SQL, the SAS communicates with powerful data manipulation and query tool. Topics covered will include selecting, subsetting, sorting and grouping data--all without the use of DATA step code or any procedures other than PROC SQL. THE STRUCTURE OF A SQL QUERY SQL is a language build on a very small number of keywords: • SELECT: columns (variables) that you want • FROM: tables (datasets) that you want • ON: join conditions that must be met • WHERE: row (observation) conditions that must be met • GROUP BY: summarize by these columns • HAVING: summary conditions that must be met • ORDER BY: sort by these columns For the vast majority of queries that you run, the seven keywords listed above are all you’ll need to know. There are also a few functions and operators specific to SQL that can be used in conjunction with the keywords above. SELECT is a statement and is required for a query. All the other keywords are clauses of the SELECT statement. The FROM clause is the only one that is required. The clauses are always ordered as in the list above and each clause can appear, at most, once in a query. The nice thing about SQL is that, because there are so few keywords to learn, you can cover a great deal in a short duration. So, let’s get on with the learning!

SQL is a programming language used to perform tasks on database using SQL you can create update and modify and delete records on a database this course can cover al the topics need to perform queries on database this course will make beginners to learn SQL from beginning and basics and also professionals who want to relearn SQL from basics

Hi With so much data stored in SQL databases, how can we get at it ? You use SQL to get at this data, no matter what the SQL Database product is ( e.g SQL Server, Oracle and many more ). Coding SQL to analyse data can be a daunting and complex task, hence the reason for building this course. In this course I will teach you how code SQL to perform data analysis in order to answer complex questions that you will encounter daily in your job. Ask yourself these simple questions ... Do you know all of the TABLE JOIN types that can be applied in a SQL query ? Have you ever used OUTER APPLY , which is so easy and powerful to use ? Can you write a running total in a single line of SQL ? Where do you use a ROLLUP statement and why would you use it ? What is LAG() ? If you could not answer these simple questions then this course will definitely change all of that for you. You definitely should know all of this to survive the SQL environment you work in ! All course materials are provided e.g. Sample databases (with real data), code scripts, practice exercises and quizzes. Don't forget, there is a 30 Day money back guarantee if this course does not deliver what you expected. Stay safe and well Best Regards Paul Data Analyst and Visualisation Engineer

Many courses teach SQL with complicated tools and methods that make it difficult for beginners to easily grasp the core concepts of database management, especially for beginners and busy professionals. This course, however, aims to simplify the method of learning SQL database management, using the most popular package available - a Python distribution called Anaconda

Are you stuck in a rut of only knowing how to use a GIS GUI? Do you want to learn how to automate tasks, but are afraid of computer programming. If so, SQL is the most powerful tool you can learn to help you perform complex GIS tasks. This course is designed to teach you how to write SQL to replicate many database and GIS tasks. We will start at a very basic overview, and then proceed to more advanced topics related to GIS. Through a series of lectures, I will work side-by-side with you to develop SQL queries that perform advanced GIS tasks, some of which might be impossible to perform in the GUI. Once my students learn GIS, they very rarely want to return back to using the GUI. By writing SQL code alongside me, you will see how solving GIS tasks in SQL is like a second nature. This is a very comprehensive course that should take multiple days to complete - but don't worry about that - you will be having a lot of fun learning how powerful SQL can be, and continually ask yourself "why didn't I start using SQL sooner!"

WHAT SOME OF MY STUDENTS SAY ABOUT THE COURSE: "It was a great course and very easy to follow especially for someone who had no experience in SQL. The examples given were simple and Dr. Cas breaks it down really well so you can understand better. She walks you through all the different queries thoroughly and also writes down some helpful hints if you get stuck. She was also very attentive when I got stuck on one of the challenges and reached out to her one late night. She helped me understand it better by giving me more guidance and helped me think outside the box. Overall, this was a great course to take and now I have another skill under my belt all thanks to Dr. Cas! Thanks for everything!" - Karla Flores , Senior Financial Analyst, Adobe (California, USA) "Excellent course and terrific inputs about every query. Majority of the job interviews that I appeared before this course had questions on SQL and I used to mess it up since I didn't have my basics strong.This course not just helped me with the basics but also with the advanced concepts. It's absolutely brilliant. I just feel completely charged up to attend any DS interview where SQL is a skill set that is asked. My motivation was not to give any chance to the interviewer/recruiter is to not provide any more opportunities to them to reject me and this helped me at least get to that stage. Rest of the outcome depends on the practice that I do. Only need some practice on the Data Cleaning section else I think I am prepared from an interview standpoint. Thanks for all the inputs and support Ava." - R Suraj Kumar "This was my first time taking an online data analysis class outside an academic setting. I worried about how the design would work for me as a working professional and if it would enable me grasp the material, but I must say that everything about the online course was smooth, convenient, and enjoyable. The concise tutorial videos, quizzes with solutions and availability of the instructor, made it easy for me to understand the topics. The method, order, and scheduling were accommodating and in my opinion, makes it convenient for anyone, anywhere to take the course, and of course, the content was very useful to me. I'm glad I took this course and I will strongly recommend it and others to follow, to anyone trying to develop more skills for data analysis. " - Clare Ofodile , Project Manager, Quality Assurance and Research Development Agency Nigeria (Lagos, Nigeria) "I like this course as it is very easy to understand and relevant for a beginner like me. I wish I could have some more courses like this one. I really enjoyed it and I started to like SQL more. A big thank you to my teacher!" - Ana Rotari This instructor is highly effective and efficient in getting the critical knowledge across. Unlike other courses, this one did not drag. Time was well managed with the instructor's teaching approach. In just three and a half hours, this course can be a career changing investment. – Jose Floresca Jr. "This course sparks my most interest in SQL and you MUST take to get strong foundation in SQL. Teacher Ava provides a very organized and informative course which is worth best 5 ***** (stars). And more than that, she always be there to support you to clarify your confusion. Believe me, after this course, your level of confidence improves a lot and exceed your expectation. For me, I'd like to attend more SQL courses from Ava in next levels. I hope she will have some good news." – Dannie Le
