Bulk Update

[Bruce Beaumont]

Hi

I have a bean with the following mapping
@Id
@Column(name="s_id", nullable=false)
private long id = 0;
  
@Basic
@Column(name="s_key", length=10, nullable=true)
private String key = null;
  
@Basic
@Column(name="s_desc", length=30, nullable=true)
private String description = null;
  
@Basic
@Column(name="s_decimal", scale=14, precision=2, nullable=true)
public BigDecimal dec = null;
  
@Basic
@Column(name="s_date", nullable=true)
public Calendar date = null;
  
@Basic
@Column(name="s_dt", nullable=true)
public Calendar dt = null;

and am trying to do a bulk update as follows

Query q = em.createQuery("update simple x set x.description = ?1, x.dec
= ?2, x.date = ?3 where x.id = ?4");
q.setParameter(1, "Test 123");
q.setParameter(2, new BigDecimal("1234.56"));
q.setParameter(3, Calendar.getInstance());
q.setParameter(4, 2l);

I get the following error:

The strange thing is that if I remove the where clause it works OK. If I
use a fetch and change the bean values it works as well.

Could anyone please give an indication for this error.

PS: The select indicated in the trace is also a bit odd as it is not in
my small test program and I do not understand why it is there. It is not
there if there is no where clause.
