You use the FOR ... IN ... LOOP statement to loop through data rows in the implicit cursor as the following syntax:
FOR row IN dml_statement LOOP
(statement block with row.field)
END LOOP;
Here "row" is a local RECORD type variable with fields automatically defined to match the fields in the data rows resulted from the DML statement. Here is a good tutorial exercise on loop through data rows with the implicit cursor:
BEGIN
FOR row IN (SELECT * FROM employees
WHERE manager_id = 101) LOOP
DBMS_OUTPUT.PUT_LINE('Name = ' || row.last_name);
END LOOP;
END;
