Setting a JPA timestamp column to be generated by the database?

Question

In my SQL Server 2000 database, I have a timestamp (in function not in data type) column of type DATETIME named lastTouched set to getdate()<

Answer 1

If you mark your entity with @DynamicInsert e.g.

@Entity
@DynamicInsert
@Table(name = "TABLE_NAME")
public class ClassName implements Serializable  {

Hibernate will generate SQL without null values. Then the database will insert its own default value. This does have performance implications See [Dynamic Insert][1].
