Question
Which of the following statements will execute successfully?INSERT INTO Student VALUES(1, 'Alice', 'Female', '20-JAN-15');INSERT INTO Student VALUES(1, "Alice", 'F', SYSDATE);INSERT INTO Student VALUES(1, 'Alice', 'F', '2015-JAN-20');INSERT INTO Student VALUES(1, 'Alice', 'F', NULL);
Solution
The successful execution of these statements depends on the structure of the "Student" table in your database. However, assuming a generic structure, here's a step-by-step analysis:
-
INSERT INTO Student VALUES(1, 'Alice', 'Female', '20-JAN-15');This statement will execute successfully if the "Student" table has exactly four columns and the data types match. The date format '20-JAN-15' is a valid Oracle date format. -
INSERT INTO Student VALUES(1, "Alice", 'F', SYSDATE);This statement will not execute successfully because double quotes are not used for string literals in SQL. Single quotes should be used instead. -
INSERT INTO Student VALUES(1, 'Alice', 'F', '2015-JAN-20');This statement will execute successfully if the "Student" table has exactly four columns and the data types match. The date format '2015-JAN-20' is a valid Oracle date format. -
INSERT INTO Student VALUES(1, 'Alice', 'F', NULL);This statement will execute successfully if the "Student" table has exactly four columns, the data types match, and the fourth column allows NULL values.
