Oracle Hello world from table

Create a simple table


CREATE TABLE MY_table (
 what VARCHAR2(10),
 who VARCHAR2(10),
mark VARCHAR2(10)
);

Insert values (you can omit target columns if you provide values for all columns)


INSERT INTO my_table (what, who, mark) VALUES ('Hello', 'world', '!' );
INSERT INTO my_table VALUES ('Bye bye', 'ponies', '?' );
INSERT INTO my_table (what) VALUES('Hey');

Remember to commit, because Oracle uses transactions


COMMIT;

Select your data:


SELECT what, who, mark FROM my_table WHERE what='Hello';
