jdbc 调用 oracle 存储过程 写大字段

表结构

create table T_IMAGE
(
ID NUMBER,
TITLE VARCHAR2(10),
IMAGE BLOB
)

  

存储过程

CREATE OR REPLACE PROCEDURE SAVE_BLOB_IMAGE2(
PC_TITLE IN VARCHAR2,
PB_IMAGE OUT BLOB
) as

BEGIN

INSERT INTO t_image(id,title,image) values(autoid.nextval,PC_TITLE,empty_blob()) //autoid,自增长序列
RETURNING image INTO PB_IMAGE;
END;
