错误，同时创建jpa表时创建新条目

即时通讯使用以下代码插入数据到JPA和我得到错误，当我试图做提交时，对象是与完整的数据，所以我不明白我失去了什么这里有什么想法？错误，同时创建jpa表时创建新条目

entityManager.getTransaction().begin(); 
    entityManager.persist(object); 
    entityManager.getTransaction().commit();

实体这个样子的所有的getter和setter

@Entity 
public class LeaveRequest { 

@Id 
@GeneratedValue(strategy = GenerationType.TABLE) 
private int id; 
private String type; 
private String from; 
private String to; 
private String length; 
private String state; 

public int getId() { 

    return id; 
}

错误是：

Internal Exception: java.sql.SQLSyntaxErrorException: Syntax error: Encountered "FROM" at line 1, column 31. 
Error Code: 20000 
Call: INSERT INTO LEAVEREQUEST (ID, FROM, LENGTH, STATE, TO, TYPE) VALUES (?, ?, ?, ?, ?, ?) 
    bind => [6 parameters bound] 
Query: InsertObjectQuery(LeaveRequest [id=1, type=VACATION, from=2012-12-27, to=2012-12-27, length=1 day, state=Rejected])
