How can I add SQL to my resume after an MCA?

SQL is used to retrieve and manage relational data. A strong MCA learner should practise SELECT queries, joins, grouping, subqueries, transactions and basic database design. When preparing for an IT role, be ready to explain how SQL works and where you would use it in a real application. This point is specifically relevant to the SQL aspect of MCA study. For this specific question about SQL, the practical takeaway is to relate the concept to your own MCA learning goal.
