Mysql报错[Err] 1054 - Unknown column 'b.borrow_id' in 'on clause'

SELECT
	br.product_id,
	d.date,
	round(sum(b.repayment_amount) / 100, 2)
FROM
	s_repayment_detail b,
	s_date d
LEFT JOIN s_borrow_repayment_detail br ON br.borrow_id = b.borrow_id
WHERE
br.product_id is not null and
	date(b.repayment_time) <= d.date 
AND d.date BETWEEN '2016-11-22'
AND '2016-11-22'
GROUP BY
	br.product_id,
	d.date

运行以上sql报错：

[Err] 1054 - Unknown column 'b.borrow_id' in 'on clause'

Mysql版本（select version();）：5.6.23-log

解决：
MySQL5.0 Bug, 要把联合的表用括号包含起来才行。

修改后的sql：

SELECT
	br.product_id,
	d.date,
	round(sum(b.repayment_amount) / 100, 2)
FROM
	(s_repayment_detail b,
	s_date d)
LEFT JOIN s_borrow_repayment_detail br ON br.borrow_id = b.borrow_id
WHERE
br.product_id is not null and
	date(b.repayment_time) <= d.date 
AND d.date BETWEEN '2016-11-22'
AND '2016-11-22'
GROUP BY
	br.product_id,
	d.date
