Question

我写了这个mysql程序，用于将客户账单详细信息插入电子商务数据库。

如果我在phpmyadmin中运行它，它会抛出任何分号的错误。我删除了分号，但它给出了以下错误

1064 - 您的SQL语法出错;检查与MySQL服务器版本对应的手册，以便在第4行使用“DECLARE addr_id INT UNSIGNED ...”附近的正确语法

我以前从未使用过程序，但我仔细检查了语法，无法弄清楚错误。

DELIMITER //

CREATE PROCEDURE addCustomer(email VARCHAR(60), status VARCHAR(15), bill_pin_id SMALLINT UNSIGNED, bill_addr VARCHAR(175), name VARCHAR(60), tel VARCHAR(15))
BEGIN
DECLARE em_id INT UNSIGNED;
DECLARE addr_id INT UNSIGNED;
DECLARE cust_id INT UNSIGNED;
DECLARE sql_error TINYINT DEFAULT FALSE;

DECLARE CONTINUE HANDLER FOR SQLEXCEPTION SET sql_error = true;


--check if customer email already exists
SELECT id INTO em_id FROM email_list WHERE email = email;

-- not sure of the return value, haven't tested it
IF em_id = 1 THEN

  -- if emails exists check if customer exists
  SELECT id INTO cust_id FROM customer WHERE email_list_id = em_id;
  IF cust_id = 1 THEN

    -- customer must have address information
    SELECT address_id INTO addr_id from customer_addr
        INNER JOIN address on address_id = address.id
        WHERE customer_id = cust_id and address = bill_addr;
  END IF
END IF

START TRANSACTION;

IF (em_id = 0) THEN

  -- if email doesn't exist, no customer no address - simple insert
  INSERT INTO email_list (email, status) VALUES (email, status);
  SELECT LAST_INSERT_ID() INTO em_id;

  INSERT INTO customer (email_list_id, full_name, phone)
      VALUES (em_id, name, tel);
  SELECT LAST_INSERT_ID() INTO cust_id;

  INSERT INTO address (pincode_id, address) VALUES (bill_pin_id, bill_addr);
  SELECT LAST_INSERT_ID() INTO addr_id;

  INSERT INTO customer_addr (address_id, customer_id)
      VALUES (addr_id, cust_id);

ELSE
  UPDATE email_list SET status = status where id = em_id;
  UPDATE customer SET full_name = name, phone = tel WHERE id = cust_id;
  UPDATE address SET pincode_id = bill_pin_id, address = bill_addr;
END IF

IF sql_error = FALSE THEN
  COMMIT;
  SELECT 'SUCCESS';
ELSE
  ROLLBACK;
  SELECT 'FAILED';
END IF

END //

试试这个解决方案，我在一些评论中添加了一些缺少的分号和空格。

CREATE addCustomer(email VARCHAR(60), status VARCHAR(15), bill_pin_id SMALLINT UNSIGNED, bill_addr VARCHAR(175), name VARCHAR(60), tel VARCHAR(15))
BEGIN
DECLARE em_id INT UNSIGNED;
DECLARE addr_id INT UNSIGNED;
DECLARE cust_id INT UNSIGNED;
DECLARE sql_error TINYINT DEFAULT FALSE;

DECLARE CONTINUE HANDLER FOR SQLEXCEPTION SET sql_error = true;


-- check if customer email already exists
SELECT id INTO em_id FROM email_list WHERE email = email;

-- not sure of the return value, haven't tested it
IF em_id = 1 THEN

  -- if emails exists check if customer exists
  SELECT id INTO cust_id FROM customer WHERE email_list_id = em_id;
  IF cust_id = 1 THEN

    -- customer must have address information
    SELECT address_id INTO addr_id from customer_addr
        INNER JOIN address on address_id = address.id
        WHERE customer_id = cust_id and address = bill_addr;
  END IF;
END IF;

START TRANSACTION;

IF (em_id = 0) THEN

  -- if email doesn't exist, no customer no address - simple insert
  INSERT INTO email_list (email, status) VALUES (email, status);
  SELECT LAST_INSERT_ID() INTO em_id;

  INSERT INTO customer (email_list_id, full_name, phone)
      VALUES (em_id, name, tel);
  SELECT LAST_INSERT_ID() INTO cust_id;

  INSERT INTO address (pincode_id, address) VALUES (bill_pin_id, bill_addr);
  SELECT LAST_INSERT_ID() INTO addr_id;

  INSERT INTO customer_addr (address_id, customer_id)
      VALUES (addr_id, cust_id);

ELSE
  UPDATE email_list SET status = status where id = em_id;
  UPDATE customer SET full_name = name, phone = tel WHERE id = cust_id;
  UPDATE address SET pincode_id = bill_pin_id, address = bill_addr;
END IF;

IF sql_error = FALSE THEN
  COMMIT;
  SELECT 'SUCCESS';
ELSE
  ROLLBACK;
  SELECT 'FAILED';
END IF;

END

Answer 2

我通过mysql控制台

执行整个过程来解决这个问题

它毫无错误地接受了它。然后，我从phpmyadmin例程选项卡访问该过程并导出语句。

我能找到的唯一区别是这个

DELIMITER $$
CREATE DEFINER=`root`@`localhost` PROCEDURE `addCustomer`(
    IN `email` VARCHAR(60),
    IN `status` VARCHAR(15),
    IN `bill_pin_id` SMALLINT UNSIGNED,
    IN `bill_addr` VARCHAR(175),
    IN `name` VARCHAR(60),
    IN `tel` VARCHAR(15)
)

-- regular procedure statements

END$$
DELIMITER ;

我在Domingo Sambo所指出的if语句之后没有添加分号时犯了一些错误。

我删除了程序并再次测试它，通过phpmyadmin查询框添加它并且它完美地工作。

无法使用mysql程序 - 语法错误
