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

This also works for me:-

@Temporal(TemporalType.TIMESTAMP)   
@Column(name = "CREATE_DATE_TIME", nullable = false, updatable = false, insertable = false, columnDefinition = "TIMESTAMP DEFAULT CURRENT_TIMESTAMP")
public Date getCreateDateTime() {
    return createDateTime;
}

public void setCreateDateTime(Date createDateTime) {
    this.createDateTime = createDateTime;
}
