Question

I have a stored procedure in an Oracle 11g database like f(a IN, b IN, c OUT).
I want to call it from JDBC in batch mode and then read all the OUT variables.
Is this possible?
I have this so far

  CallableStatement statement = connection.prepareCall("f(?, ?, ?)");
  for(Item i : items) {
     int i = 0;
     statement.setString(++i, item.getA());
     statement.setString(++i, item.getB());
     statement.registerOutParameter(++i, Types.NUMERIC);
     statement.addBatch();
  }
  statement.executeBatch();
  int[] answers =  ?

Thanks

Sadly, no.

The ability to make batch updates is the same for CallableStatement
objects as it is for PreparedStatement objects. In fact, a
CallableStatement object is restricted to the same functionality that
a PreparedStatement object has. More precisely, when using the batch
update facility, a CallableStatement object can call only stored
procedures that take input parameters or no parameters at all.
