Question

我编写了mysql存储过程的代码，它显示了语法错误我不知道我做了什么错误。有人帮我请。

DELIMITER $$

DROP PROCEDURE IF EXISTS `aad_adr`.` PROCEDURE MonthlySalesReport(fromdate DATE,todate DATE)` $$
CREATE PROCEDURE `aad_adr`.` PROCEDURE MonthlySalesReport(fromdate DATE,todate DATE)` ()
BEGIN
Declare fd DATE;
Declare ed DATE;
SET fd=fromdate;
SET ed=todate;
WHILE DATE(fd)<=DATE(ed)DO
select bill_master.bill_no,DATE_FORMAT(bill_master.bill_date, '%y/%m/%d') AS 'formatted_date',transaction.product_id,transaction.tax_amount,transaction.amount,transaction.amount-transaction.tax_amount as 'without_tax ',product_master.Product_name,product_master.vat from bill_master inner join transaction on bill_master.bill_no=transaction.bill_no inner join product_master on transaction.product_id=product_master.product_id where vat='14.50' and DATE_FORMAT(bill_master.bill_date, '%y/%m/%d') fd;
SET fd=DATE_ADD(fd,INTERVAL 1 DAY);
END WHILE;
END $$

DELIMITER;

错误：

Script line: 4  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 'fd;
SET fd=DATE_ADD(fd,INTERVAL 1 DAY);
END WHILE;
END' at line 8

Answer 1

首先你有两个错误：第一个是PROCEDURE的名称

CREATE PROCEDURE `aad_adr`.` PROCEDURE MonthlySalesReport(fromdate DATE,todate DATE)` ()

---＆gt;

CREATE PROCEDURE `aad_adr`.`MonthlySalesReport`(fromdate DATE,todate DATE)

所以你的程序应该是这样的：

DELIMITER $$
DROP PROCEDURE IF EXISTS `aad_adr`.`MonthlySalesReport`$$
CREATE PROCEDURE `aad_adr`.`MonthlySalesReport`(fromdate DATE,todate DATE)
BEGIN
Declare fd DATE;
Declare ed DATE;
SET fd=fromdate;
SET ed=todate;
WHILE DATE(fd)<=DATE(ed)DO
select 
bill_master.bill_no,
DATE_FORMAT(bill_master.bill_date,'%y/%m/%d') AS 'formatted_date',
transaction.product_id,
transaction.tax_amount,
transaction.amount,
transaction.amount-transaction.tax_amount as 'without_tax ',
product_master.Product_name,
product_master.vat 
from 
bill_master inner join transaction on bill_master.bill_no=transaction.bill_no 
inner join product_master on transaction.product_id=product_master.product_id 
where
vat='14.50' and vat='14.50' and DATE_FORMAT(bill_master.bill_date, '%y/%m/%d');
SET fd=DATE_ADD(fd,INTERVAL 1 DAY);
END WHILE;
END $$
DELIMITER ;

Answer 2

您在选择查询中出错，您在条件中调用错误。因此，只需删除where子句中的DATE_FORMAT，然后再需要进行一次修改，只需将DELIMITER;替换为DELIMITER$$。

更新1：修改了SP的有效名称。

所以更新的代码是：

DELIMITER $$

DROP PROCEDURE IF EXISTS `aad_adr`.`MonthlySalesReport` $$
CREATE PROCEDURE `aad_adr`.`MonthlySalesReport`(IN fromdate DATE,IN todate DATE)
     BEGIN
       DECLARE fd DATE;
       DECLARE ed DATE;
       SET fd=fromdate;
       SET ed=todate;
       WHILE DATE(fd)<=DATE(ed)DO
             SELECT bill_master.bill_no,DATE_FORMAT(bill_master.bill_date, '%y/%m/%d') AS 'formatted_date',transaction.product_id,transaction.tax_amount,transaction.amount,transaction.amount-transaction.tax_amount AS 'without_tax ',product_master.Product_name,product_master.vat FROM bill_master INNER JOIN TRANSACTION ON bill_master.bill_no=transaction.bill_no INNER JOIN product_master ON transaction.product_id=product_master.product_id WHERE vat='14.50' AND bill_master.bill_date=fd;
          SET fd=DATE_ADD(fd,INTERVAL 1 DAY);
       END WHILE;
    END $$
DELIMITER$$
