Question

我在oracle数据库中有以下存储过程

    create or replace procedure cust_details(idValue    Custdetails.id_value%type,
                                                     idUser    Custdetails.id_user%type,
                                                     idType    Custdetails.id_type%type,
                                                     nickName  Custdetails.nickname%type,
                                                     imageData Custdetails.IMAGE%type) IS
  bene_id     number(10);
  current_seq number(10);
  isExist     number(2);
BEGIN

  select count(*)
    into isExist
    from iddetails
   where id_value = idValue;

  if isExist = 0 then
    select beneficiary_seq.nextval into current_seq from dual;
    insert into details
      (beneficiary_id, date_added)
    values
      (current_seq, sysdate);
    insert into Custdetails
      (beneficiary_id, id_user, nickname,image)
    valuesnumber 
      (current_seq, idUser, nickName,imageData);
    insert into iddetails
      (beneficiary_id, id_type, id_value)
    values
      (current_seq, idType, idValue);
  else
    select beneficiary_id
      into bene_id
      from iddetails
     where id_value = idValue;
    insert into Custdetails
      (beneficiary_id, id_user, nickname,image)
    values
      (bene_id, idUser, nickName,imageData);
  end if;
END;

--Custdetails.idValue is varchar2(40)
--Custdetails.IMAGE is Blob

我从java类中调用它，如下所示：

 CallableStatement callableStatement = con.prepareCall("{CALL cust_details(?,?,?,?,?)}");
    callableStatement.setString(1, "9855154");
callableStatement.setString(2, "123");
callableStatement.setString(3, "sdsd");
callableStatement.setString(4, "ssdsd");
    byte [] imageData = l_rs.getBlob  (0); // setting bytes
    if(// if byte array has data){ 
        Blob imgDataBlob = con.createBlob();
        imgDataBlob.setBytes(1, imageData);
        callableStatement.setBlob(5, imgDataBlob);
    }
    else{
        // even this is giving same error i also tried OracleTypes.Blob
        callableStatement.setNull  (2,  java.sql.Types.BLOB); 
    }
        callableStatement.execute();

但调用此过程会在if和else情况下给出以下错误

引起：java.sql.SQLException：ORA-06550：第1行第7列： PLS-00306：调用'CUST_DETAILS'
时参数的数量或类型错误

任何想法我在这里做错了什么

我有以下工作正常，驱动程序我正在使用Ojdbc14.jar

CREATE OR REPLACE PROCEDURE my_proc (idvalue      NUMBER,
    imagedata     tobedeleted.img%TYPE
                                                )
IS
BEGIN
    INSERT INTO tobedeleted
      VALUES   (idvalue, imagedata
                  );
END my_proc;

Java代码

    ResultSet res = sta.executeQuery(
            "SELECT * FROM TOBEDELETED for update "); 
          while (res.next()) {
             myblob = res.getBlob("IMG");

          }       
    callablestatement = 
            conn.prepareCall("{CALL my_proc(?,?)}");
    callablestatement.setInt(1, 100);        
            if(myblob==null){            
        callablestatement.setNull(2,java.sql.Types.BLOB); 

    }
    else {
        byte[] chuck = {(byte)0x00, (byte)0x00, (byte)0x00,
                  (byte)0x00, (byte)0x00, (byte)0x00};
                myblob.setBytes(1,chuck);
    callablestatement.setBlob(2,myblob); 
    }
    int affectedRows = callablestatement.executeUpdate();

在存储过程中插入Blob null时，参数的数量或类型错误
