The statements you use to add, change, or delete data are called data modification statements, also referred to as the data modification language (DML) part of SQL. The three main DML statements are:
INSERT statement adds new rows to a table
UPDATE statement changes existing rows in a table
DELETE statement removes specific rows from a table
Any single INSERT, UPDATE, or DELETE statement changes the data in only one table or view.
In addition to the statements above, the LOAD TABLE and TRUNCATE TABLE statements are especially useful for bulk loading and deleting of data.
