从2006年09月--2009年1月,我的大学生活走近了毕业。从2009年03月--2014年12月,我作为一名IC卡初始化的员工结束了工作间隙性结束;从2015年01月--现在,处于待业培训间段。
IC 卡初始化虽然程序化,枯燥烦味。可其中的数据库也是耐人寻味。现摘录出来,让那段时间尘封。
IC卡的初始程序为:一个VB程序(录入程序);两个数据库(一个SQL2005,作为初始化库、检查库;一个Mysql,作为基准库)。
现将一些常用的语句,COPY下来:
SELECT
a.kahao,a.kahao1,‘1‘
FROM [zk].[dbo].[zgsku] a,
(select kahao1,max(lrrq) lr from [zk].[dbo].[zgsku] group by kahao1) b
where a.kahao1=b.kahao1 and a.lrrq=b.lr
and (a.kahao1 >=‘00664401‘and a.kahao1 <=‘00666400‘)
order by lrrq asc
1.kahao为内码,kaohao1为外码头;
2.[ZK]为总库的汉语拼音的首字母;
3.[zgsku]为总公司库的汉语拼音缩写;
4.order by 为排序;
5. desc 为降序的英文缩写;
6. lrrq 为录入日期的汉语拼音的缩写;)
其中的a\ b 是什么意思????
SELECT
a.kahao, a.kahao1,‘1‘
FROM [zk].[dbo].[zgsku] a,
(SELECT
kahao1, max(lrrq) lr
FROM [ZK].[DBO].[zgsku]
group by kahao1) b
where a.kahao1=b.kahao1 and a.lrrq=b.lr
and (a.kahao1>=‘00664401‘ and a.kahao1<=‘00666400‘)
order by Lrrq asc
删除坏卡:
delete from [zk].[dbo].[zgsku] where kahao=‘12f4b372‘
select from [zk].[dbo].[zgsku]
where kahao = ‘6d942891‘
SELECT
a.kahao,a.kahao1,‘1‘
FROM [zk].[dbo].[zgsku] a,
(select kahao1,max(lrrq) lr from [zk].[dbo].[zgsku] group by kahao1) b
where a.kahao1=b.kahao1 and a.lrrq=b.lr
and (a.kahao1 in
(‘00523831‘,‘00523862‘
))
order by lrrq desc
SELECT
a.kahao,a.kahao1,‘1‘
FROM [zk].[dbo].[zgsku] a,
(select kahao1,max(lrrq) lr from [zk].[dbo].[zgsku] group by kahao1) b
where a.kahao1=b.kahao1 and a.lrrq=b.lr
and (a.kahao in
(‘00964608‘,‘00841429‘))
--and lrrq>=‘2010-08-11‘
order by lrrq desc
delete from [zk].[dbo].[zgsku] where kahao in (‘0bd56771‘)
--(内卡号和外卡号的顺序不能颠倒,内码在前,外码在后)
select kahao1,kahao from [zk].[dbo].[zgsku] where kahao1 in (
‘00985289‘,‘00981928‘,‘00985211‘,‘00982295‘,‘00985319‘)order by kahao1 desc
--机打票
--查询录卡记录
--select count(*) FROM [zk].[dbo].[zgsku] where lrrq between‘2013-01-01‘and ‘2013-09-09‘
整盒卡倒入倒出:
select ‘insert into ic_basic_info_jm values (‘‘‘+a.kahao1+‘‘‘,‘‘‘+a.kahao+‘‘‘,NULL,‘‘正常‘‘,‘‘收回‘‘,‘‘程序员‘‘,‘‘‘+a.lrrq+‘‘‘,null,null);‘ as s
from [zk].[dbo].[zgsku] a where a.kahao1 >=‘01302001‘and a.kahao1 <=‘01303000‘ order by lrrq desc
(注释:
1.select 插入;
2.‘insert into ic_basic_info_jm values
( ‘‘‘+a.kahao1+‘‘‘, ‘‘‘+a.kahao+‘‘‘, NULL, ‘‘正常‘‘, ‘‘收回‘‘, ‘‘程序员‘‘, ‘‘‘+a.lrrq+‘‘‘, null, null);‘
嵌入式内容
3.insert into ic_card_infor_jm 插入表ic_card_jm(mysql数据库中的张表);
4.( ‘‘‘+a.kahao1+‘‘‘, ‘‘‘+a.kahao+‘‘‘, NULL, ‘‘正常‘‘, ‘‘收回‘‘, ‘‘程序员‘‘, ‘‘‘+a.lrrq+‘‘‘, null, null)
‘‘‘+a.kahao1+‘‘‘对应mydql中的ic_Card_no;‘‘‘+a.kahao+‘‘‘对应mysql中的ic_Card_inner_no;
null对应business_station; ‘‘正常‘‘对应status;‘‘收回‘‘对应dispath_status; ‘‘程序员‘‘对应operator;
‘‘‘+a.lrrq+‘‘‘对应Update_date;null对应area_code; null对应 dev_id;)
5.aS s 将以上命名为s;
6.from [zk].[dbo].[zgsku] a 来自表[zk].[dbo].[zgsku] a;
7.where (a.kahao1 >=‘01269001‘and a.kahao1 <=‘01270000‘)限制条件;
8.order by lrrq desc lrrq的先后排序;)
零散卡查询:
select ‘insert into ic_basic_info_jm values (‘‘‘+a.kahao1+‘‘‘,‘‘‘+a.kahao+‘‘‘,NULL,‘‘正常‘‘,‘‘收回‘‘,‘‘程序员‘‘,‘‘‘+a.lrrq+‘‘‘,null,null);‘ as s
from [zk].[dbo].[zgsku] a where a.kahao1 in (‘01250100‘,‘01237991‘,‘01194611‘,‘01159788‘,‘01192434‘,
‘01192451‘,‘01192570‘,‘01221468‘,‘01194651‘,‘01168371‘,
‘01178321‘,‘01226527‘,‘01300632‘,‘01300633‘,‘01300634‘) order by lrrq desc
