从java运行postgresql函数时出错

我们最近改用postgresql enterpriseDB，我将一个函数移到了另一个位置，但当我运行它时，我得到了：

com.edb.util.PSQLException: ERROR: bind message has 2 result formats but query has 1 columns

功能是：

CREATE OR REPLACE FUNCTION receive_item(qtyexpected integer, qtyrcvd integer, reasoncd character varying, commenttext character varying, whs character varying, rcvrnbr character varying, ponbr character varying, itemid character varying) RETURNS integer AS
$BODY$
  rcvrDtlId integer;  
begin
  rcvrDtlId := 0;

  begin
    update rcvr_dtl set 
    qty_expected = qtyExpected, qty_received = qty_received + qtyRcvd, reason_cd = reasonCd, comments = commentText 
    where warehouse = whs and rcvr_nbr = rcvrNbr and po_nbr = poNbr and item_nbr = itemId
    returning rcvr_dtl_id into rcvrDtlId;                             
  exception
     when no_data_found then
        null;
  end;                              

  return rcvrDtlId;
end$BODY$
LANGUAGE edbspl VOLATILE NOT LEAKPROOF
COST 100;

它被称为：

sql= "{? = CALL receive_item(?,?,?,?,?,?,?,?)}";
m_ReceiveItem = m_Conn.prepareCall(sql);
m_ReceiveItem.registerOutParameter(1, Types.INTEGER);
m_ReceiveItem.setInt(2, msg.getQtyExpected());
m_ReceiveItem.setInt(3, msg.getQtyReceived());
m_ReceiveItem.setString(4, msg.getReasonCode());
m_ReceiveItem.setString(5, msg.getComments());
m_ReceiveItem.setString(6, msg.getFacilityNbr());
m_ReceiveItem.setString(7, msg.getRcvrNbr());
m_ReceiveItem.setString(8, msg.getPoNbr());
m_ReceiveItem.setString(9, msg.getSku());
m_ReceiveItem.execute();
rcvrDtlId = m_ReceiveItem.getInt(1);

我似乎找不到任何与此错误相关的信息。为什么上面的代码会出现此错误？

我可以通过将语法从？=呼叫选择*from receive_item…

的语法实际上错误似乎特定于edb驱动程序，该字符串在普通postgres java驱动程序源中不存在。如果您将edb驱动程序替换为香草postgres JDBC驱动程序，它是否工作？EnterpriseDB没有发布他们的源代码，我不认为是为了驱动程序，所以很难看到发生了什么。PostgreSQL没有区分存储过程和用户定义函数。它们都被认为是相同的，并且都是通过SELECT访问的。
