调用Mysql存储过程输入输出参数

来源: 作者: 时间:2016-01-30 09:02 【

存储过程如下:DELIMITER $$USE `gface_taisau`$$DROP PROCEDURE IF EXISTS `p_InsertFace`$$CREATE DEFINER=`root`@`localhost` PROCEDURE `p_InsertFace`( IN Id BIGINT

存储过程如下:

DELIMITER $$

USE `gface_taisau`$$

DROP PROCEDURE IF EXISTS `p_InsertFace`$$

CREATE DEFINER=`root`@`localhost` PROCEDURE `p_InsertFace`(
IN Id BIGINT(8),
IN UserID BIGINT(8),
IN FeaLen SMALLINT(2),
IN Fea BLOB,
IN ImgUrl CHAR(64),
IN Type1 INT(4),
IN Type2 INT(4),
IN Type3 INT(4),
IN Type4 CHAR(32),
IN Remarks CHAR(64),
OUT OID BIGINT(8))
BEGIN

DECLARE l_Id BIGINT(8);
SET l_Id= 0;
IF (Id>0) THEN
SET l_Id=Id;
END IF;


INSERT INTO t_face
(ID,
UserID,
FeaLen,
Fea,
ImgUrl,
Type1,
Type2,
Type3,
Type4,
Stamp,
IsDel,
UpdateTime,
Remarks
)
VALUES
(l_Id,
UserID,
FeaLen,
Fea,
ImgUrl,
Type1,
Type2,
Type3,
Type4,
NOW(),
0,
NOW(),
Remarks
);


IF(l_Id=0) THEN
SET OID=LAST_INSERT_ID();
END IF;

END$$

DELIMITER ;

用到的结构体如下

#define MAX_FEA_LEN 10240 //定义10k
#define MAX_URL_LEN 200
//图片信息
typedef struct _FACE_INFO
{
//ULONGLONG nID;
ULONGLONG nID;

DWORD nFeaLen;
TCHAR szFea[MAX_FEA_LEN];
TCHAR szUrl[MAX_URL_LEN];
DWORD nType1;
DWORD nType2;
DWORD nType3;
TCHAR szType4[32];
TCHAR szStamp[20];//2012-08-08 08:08:08
TCHAR szRemarks[64];
