Data Manipulation Language (DML)

INSERT, UPDATE, and DELETE statements define the DML commands. All of these may use joins, subqueries, correlated subqueries, and in-line views. The in-line views must be contained within a subquery or correlated subquery. DML commands can insert, update, or delete one to many rows of data.

INSERT Statements

The INSERT statement acts on rows of data. Inserting data into tables can be done row by row or by groups of rows. You have two potential ways to create insertion anomalies when inserting data.
