MySQL 存储过程语法错误

Question

我的 mysql 版本是 5.5，当运行这个 mysql 存储过程是 return 这个错误。

代码：

CREATE DEFINER = CURRENT_USER PROCEDURE `getReceiptNumber`(IN bankcode 
varchar,IN receipttype varchar,OUT seq int)
BEGIN
    update receipt_number 
    set seq_number = (seq_number + 1) 
    where bank_code = bankcode and receipt_type = receipttype;
    select seq_number from receipt_number where bank_code = bankcode and 
receipt_type = receipttype into seq; 
END;

Table结构：

CREATE TABLE `receipt_number` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `bank_code` varchar(255) DEFAULT NULL,
  `cur_date` varchar(255) DEFAULT NULL,
  `cur_year` int(11) DEFAULT NULL,
  `receipt_type` varchar(255) DEFAULT NULL,
  `seq_number` int(5) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=latin1;

错误：

[Err] 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'IN receipttype varchar,OUT seq int) BEGIN update receipt_number set seq_nu' at line 1

Answer 1

您没有提到参数 varchar 的大小，

试试下面的代码。

DELIMITER $$
CREATE DEFINER = CURRENT_USER PROCEDURE getReceiptNumber(IN bankcode VARCHAR(10),IN receipttype VARCHAR(10),OUT seq INT)
BEGIN
    UPDATE receipt_number 
    SET seq_number = (seq_number + 1) 
    WHERE bank_code = bankcode AND receipt_type = receipttype;
    SELECT seq_number FROM receipt_number WHERE bank_code = bankcode AND 
receipt_type = receipttype INTO seq; 
END$$

DELIMITER ;
