mysql update使用要update的字段查询

leokim / / 未分类 
CREATE TABLE tmp_voucher
SELECT a.voucher_id
FROM voucher a, voucher_action b
WHERE a.stock_id = 50 AND a.status_id != 40 AND a.voucher_id = b.voucher_id AND b.action_id = 60
GROUP BY a.voucher_id

UPDATE voucher a, tmp_voucher b SET a.stock_id = 60
WHERE a.voucher_id = b.voucher_id

drop table tmp_voucher;

 

使用以上方法解决，

因为mysql不能直接update查询子句内的字段否则会报错“you can't specify target table 'xxxx' for update in from CLAUSE”

Mysql Concat使用

leokim / / 未分类

CONCAT用的已经很多了 今天用到的时候是需要连接多次payment的log，每一次payment一次就记录到同一个field里。而开始的时候我用concat发现没有效果，然后查了一下concat函数才了解到如果concat中间的参数如果有null那么concat出来的结果就是null，解决方法如下：

CONCAT(ifnull($tmp_key,''), '|', '$tmp_val')

MySQL 中集合的差的运算方法【记录待参考】

leokim / / 未分类

1. http://www.blogjava.net/rox/archive/2006/09/01/67008.html

MySql中集合运算非常规实现

MySql只支持Union(并集)集合运算，好像也是4.0以后才有的；
但是对于交集Intersect、差集Except，就没有实现了。
一般的解决方案用in和not in来解决，小量数据还可以，但数据量大了效率就很低了。
其实，可以使用Union来实现另外两种的运算，当然是没有办法的办法。

差集Except:
SELECT ID FROM (
SELECT DISTINCT A.AID AS ID FROM TABLE_A A
UNION ALL
SELECT DISTINCT B.BID AS ID FROM TABLE_B B
)TEMP GROUP BY ID HAVING COUNT(ID) = 1

交集Intersect:
SELECT ID FROM (
SELECT DISTINCT A.AID AS ID FROM TABLE_A A
UNION ALL
SELECT DISTINCT B.BID AS ID FROM TABLE_B B
)TEMP GROUP BY ID HAVING COUNT(ID) = 2

不过，上述方法的功能也有限，
只能用来检查某个id是不是A、B表中都存在，
或者只存在于A、B表其中之一，
并不能对id在某表中多次出现做出检查。
而且，差集是有先后之分，这里没有。

1。求两表差集, ewb_t_books 是图书表，ewb_t_title是图书分类表,通过bt_titleid（not null）连接。
找出分类不存在的图书
a.子查询使用not in
#explain extended 
SELECT book_id,bt_titleid
FROM ewb_t_books b
WHERE bt_titleid NOT IN (SELECT bt_titleid FROM ewb_t_title)
#show warnings;

b.子查询 not exists
#explain extended 
SELECT book_id,bt_titleid
FROM ewb_t_books b
WHERE NOT EXISTS (SELECT * FROM ewb_t_title a WHERE b.bt_titleid= a.bt_titleid )
#show warnings;

c.左连接判断右表is null
#explain extended 
SELECT book_id,bt_titleid
FROM ewb_t_books LEFT JOIN ewb_t_title b USING (bt_titleid) 
WHERE ISNULL(b.bt_titleid)
#show warnings;

总结：简单测试了一下，not in最慢，其他两个平分秋色，有待考证。

select * from employee where salary<>3000;

　　对这个查询，可以改写为不使用NOT：

select * from employee where salary<3000 or salary>3000;

　　虽然这两种查询的结果一样，
