How much time should I spend learning SQL during 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. Students can judge their progress in SQL by solving problems independently instead of depending entirely on guided tutorials. 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.
