在存储过程中想传入一个二进制数组,保存到Oracle中的blob字段中

程序出现下面错误:

我的存储过程是这样写的,请大侠们指点一下

PROCEDURE UP_BINARYOBJECTADD(OBJECTID NUMBER,OBJECTTYPE VARCHAR2,OBJECTVALUE LONG RAW,OBJECTLENGTH NUMBER)

IS

B_OBJECTVALUE BLOB;

BEGIN

INSERT INTO TBLBINARYOBJECT(OBJECTID,OBJECTTYPE,OBJECTVALUE)

VALUES(OBJECTID,OBJECTTYPE,EMPTY_BLOB())

RETURNING OBJECTVALUE INTO B_OBJECTVALUE;

DBMS_LOB.WRITE(B_OBJECTVALUE,OBJECTLENGTH,0,OBJECTVALUE);

END UP_BINARYOBJECTADD;
