MySQL存储过程带in和out参数以及PHP,PB如何调用的小例子

mysql> DELIMITER $$
mysql> USE test $$
Database changed
mysql> DROP PROCEDURE IF EXISTS `sp_add`$$
Query OK, 0 rows affected (0.00 sec)

mysql> CREATE PROCEDURE sp_add(a INT, b INT,OUT c INT)
 -> BEGIN 
 -> SET c=a+ b;
 -> END$$
Query OK, 0 rows affected (0.00 sec)

mysql> DELIMITER ;

mysql> CALL sp_add (1,2,@c);
Query OK, 0 rows affected (0.00 sec)mysql> SELECT @c;
+------+
| @c |
+------+
| 3 |
+------+
1 row in set (0.00 sec)mysql>

一个稍微复杂的例子:

mysql> show create table t_BillNo;
+----------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Table | Create Table |
+----------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| t_BillNo | CREATE TABLE `t_billno` (
 `SaleNo` bigint(20) DEFAULT NULL,
 `bmh` varchar(20) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 CHECKSUM=1 DELAY_KEY_WRITE=1 ROW_FORMAT=DYNAMIC |
+----------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)

mysql> select * from t_BillNo;
+--------+------+
| SaleNo | bmh |
+--------+------+
| 1 | 2 |
| 4 | 3 |
| 4 | 5 |
| 7 | 7 |
| 12 | 8 |
+--------+------+
5 rows in set (0.00 sec)

mysql> 
mysql> DELIMITER $$
mysql> USE test $$
Database changed
mysql> DROP PROCEDURE IF EXISTS `sp_GetMaxNumber`$$
Query OK, 0 rows affected (0.01 sec)

DELIMITER $$

DROP PROCEDURE IF EXISTS `sp_GetMaxNumber`$$
CREATE PROCEDURE sp_GetMaxNumber (IN v_bmh VARCHAR(6), OUT v_MaxNo INT)
BEGIN
	START TRANSACTION;
	UPDATE t_BillNo
	SET SaleNo = IFNULL(SaleNo,0)+1 
	WHERE bmh = v_bmh;
	IF @@error_count = 0 THEN
	BEGIN
	 SELECT Saleno INTO v_MaxNo FROM t_BillNo WHERE bmh = v_bmh;
	COMMIT;
	END;
	ELSE
	BEGIN
	 ROLLBACK;
	 SET v_MaxNo = 0;
	END;
	END IF;
END$$
DELIMITER ;

如何在php中调用MySQL的存储过程?本人没有测试过,从朋友那里借鉴过实例,如下:

$sql = "call test.sp_GetMaxNumber(8,@c);";
mysql_query($sql);//调用sp_GetMaxNumber的存储过程
$result = mysql_query('select @c;');
$array = mysql_fetch_array($result);
echo '<pre>';print_r($array);

但是在PB中调用,报错如下(来自itpub的网友的例子),有类似经历的朋友请分享下经验啊:

在PB W_MAIN窗体的CB_1.CLICK事件中：

string ls_bmh, ls_errtext
int li_maxno
ls_bmh = '0901'
sp_GetMaxNumber(ls_bmh, li_maxno)
ls_errtext = sqca.sqlerrtext
messagebox('Error',string(li_maxno)+' ' +sqlca.sqlerrtext)

但PB显示显示错误：

0 SQLSTATE = 37000
[MYSQL] [ODBC 5.1 DRIVER]YOU HAVE AN ERROR IN YOUR SQL SYNTAX;CHECK THE MANUAL THAT CORRESPONDS TO YOUR MYSQL SERVER VERSION FOR THE RIGHT SYNTAX TO USE
