Top Tutor I have 15 years of IT industry experience and work as a Deputy Manager at a reputed MNC. My professional experience includes working with MS SQL Server, and I hold certifications in MS SQL Server and DevOps. I have a strong passion for SQL programming and enjoy sharing my technical knowledge with students and aspiring IT professionals. My approach to teaching SQL is focused on building a strong foundation, explaining concepts clearly, and helping learners understand the logic behind SQL queries. My SQL training covers fundamental concepts such as SELECT statements, filtering, sorting, aggregate functions, joins, subqueries, and common table expressions (CTEs). I also cover database objects and advanced SQL programming topics, including stored procedures, user-defined functions, triggers, transactions, and error handling. I emphasize understanding concepts rather than simply memorizing queries. I explain how SQL statements work, demonstrate their usage through examples, and encourage learners to practise writing queries independently. I also provide SQL interview questions and answers as assignments to help students revise important concepts, strengthen their problem-solving skills, and prepare for technical interviews. My training is suitable for beginners, students, freshers, and working professionals who want to learn MS SQL Server or improve their existing SQL programming knowledge. I aim to adapt my explanations to each learner's understanding and learning objectives. My goal is to make SQL programming easier to understand and help learners develop the confidence to write queries and solve SQL-related problems independently. Keep Coding... Keep Learning!
A very nice experience , teaching methodology is easy to understand. I thank Mr Rupesh Vaingankar for value of my money.
