The payload blah'; DROP TABLE Creditcard; -- is an example of which SQL action?

• A. Delete a row
• B. Drop a table
• C. Truncate a table
• D. Remove a table

Answer: (B)

This payload tests how SQL injection can alter the database schema by executing a destructive command. The input ends the first statement with a semicolon, then issues DROP TABLE Creditcard;, which tells the database to remove the entire table named Creditcard along with its data and structure. The -- starts a comment, ensuring any remaining input is ignored and the attack isn’t thwarted by syntax issues. This is distinta from deleting a single row (DELETE), which targets specific records; from truncating (TRUNCATE TABLE), which removes all rows but leaves the table itself intact; or from any non-existent command like removing a table via an unsupported action. The explicit operation performed here is dropping a table, making it the correct interpretation.
