PL/SQL extends SQL by adding which type of features ?
Answer: C
PL/SQL adds procedural programming features to SQL.
SQL is declarative: each statement says what data to work on, not how. PL/SQL, Oracle's procedural extension, wraps SQL in a block-structured language with variables, conditions (IF), loops, cursors, exception handling, procedures, functions, packages and triggers.
It provides no graphical interface and is not a networking extension. Because one option is correct, 'None of these' is wrong.
