工作中遇到的SQL

标签：inner   desc   lis   order by   ace   模糊查询   oom   and   like   

1.根据a表中的字段col,修改b表中的col

UPDATE a INNER JOIN b ON a.id = b.id SET b.col = xx WHERE a.col = xx

2.模糊查询 like 的替换为FIND_IN_SET

SELECT
*
FROM
	sku a
LEFT JOIN classroom b ON a.targetId = b.id
WHERE
	FIND_IN_SET(59, REPLACE(a.sn, ‘|‘, ‘,‘))
AND a.targetType = "classroom"
AND b.recommended = 1
AND b.`status` = ‘published‘
GROUP BY
	a.targetId
ORDER BY
	b.recommendedSeq DESC,
	b.recommendedTime DESC;
