Is certification in SQL useful 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. If your target role involves SQL, include at least one demonstrable project rather than mentioning the topic only as a skill. 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.
