select * from table where age>= 35;
(b)
Update:
It allows you to update a new value to records.

Update table set color= green where fruit=apple;
(c)
Insert:

(d) Alter:
It allows you to create alternations on the table.
ALter table loopies add origin varchar(50);
(e) Delete:
It allows you to delete a value from a record.
Delete from Loopies where fruit=apple;
