更新campaign需要修改的地方

SELECT *
FROM voucher_campaign_issue_request
WHERE request_id IN (11591)
SELECT * FROM voucher_request_approve WHERE request_id IN (11591) SELECT * FROM voucher_receipt_numbers where voucher_ids like 'B176,42177%'
select e.prefix, e.suffix, length(f.voucher_text) AS len, e.start_no, e.end_no, f.voucher_value , e.total_vouchers, e.total_value, d.type_desc, h.user_name, a.request_time, a.`request_remarks`, d.type_name from jurongpoint.voucher_request_approve a, jurongpoint.voucher_campaign_issue_request b, jurongpoint.voucher_campaign c ,jurongpoint.voucher_lkup_type d, jurongpoint.voucher_batch_no_section e, jurongpoint.voucher f, evo_central_config.customer_user h where `request_time` between '2014-08-01 00:00:00' and '2014-12-05 23:59:59' and a.`from_stock` = '35' and a.`to_stock` = '50' and a.request_id = b.request_id and b.campaign_id = c.campaign_id and c.type_id = d.type_id and e.batch_id = a.batch_id and e.prefix = f.prefix and e.suffix = f.suffix and e.start_no = f.voucher_no and a.request_user = h.user_id and d.type_name = 'partner' order by a.request_time desc
mysql update使用要update的字段查询
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”

Extend Voucher’s SQL

Mysql Concat使用
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】
1. http://www.blogjava.net/rox/archive/2006/09/01/67008.html
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。
b.子查询 not exists c.左连接判断右表is null 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, |
