mysql为select结果集添加序号列

两个函数简单搞定

DELIMITER $$

USE `oso_isp`$$

DROP FUNCTION IF EXISTS `rownum_reset`$$

CREATE FUNCTION `rownum_reset`() RETURNS INT(11)
BEGIN
	SET @rno = 0;   
	RETURN 1; 
END$$

DELIMITER ;

　　

DELIMITER $$

USE `oso_isp`$$

DROP FUNCTION IF EXISTS `rownum`$$

CREATE  FUNCTION `rownum`() RETURNS INT(11)
BEGIN
	/* 用法如： 
 		SELECT 
		`rownum`(
		)      AS `id`,
		t.*
		FROM TABLE t
		WHERE rownum_reset() = 1
	*/
	
	SET @rno = @rno + 1;   
	RETURN @rno;  
    
    
END$$

DELIMITER ;

　　

查询结果测试

测试代码：

SELECT
  `rownum`(
)			AS `row_num`
  ,`a`.`stock_in_date` 	AS `stock_in_date`
  ,`a`.`dinner_type`   	AS `dinner_type`
  ,`a`.`stockroom_id`  	AS `stockroom_id`
  ,SUM(`a`.`dinner_num`)
			AS `dinner_num`
  ,SUM((SELECT SUM(`wh_stock_in_order_item`.`total_price`) FROM `wh_stock_in_order_item` WHERE (`wh_stock_in_order_item`.`stock_in_order_id` = `a`.`id`))) 
			AS `total_price`
  ,COUNT(0)            	
			AS `order_num`
  ,GROUP_CONCAT(DISTINCT (SELECT `staff`.`name` FROM `staff` WHERE (`staff`.`id` = `a`.`buyer_id`)) SEPARATOR ',') -- 行变列
			AS `buyer_name`
FROM `wh_stock_in_order` `a`
WHERE ((`a`.`is_deleted` = 0)
       AND (`a`.`status` = 1)
       AND (`rownum_reset`() = 1)) -- 初始化序号列从1开始
GROUP BY `a`.`stock_in_date`,`a`.`dinner_type`,`a`.`stockroom_id`
ORDER BY `a`.`stock_in_date`,`a`.`dinner_type`
