/*第七章 7.2九大算法实例*/

/*第一算法 查记账凭证的算法

知识点:查的是记账凭证而不是明细账。一张凭证是多条记录的集合,而记录只是一条 解题规则:一个条件二张表,二个条件三张表,三个条件四张表。*/

--分析:从题意看只有一个决定条件,即科目为主营业务收入,所以要用二张表相连,a表是查询结果凭证,用b表设条件。

--例:检索出所有现金支出为整千元的记账记录。

Select * from gl_accvouch where ccode='101' and abs(mc00)=0 and mc<>0

--例:检索出所有现金收支大于1000元的记账凭证。 Select b.* from gl_accvouch a join gl_accvouch b

on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id where a.ccode='101' and (a.md>1000 or a.mc>1000)

--例:检索出所有凭证的现金科目的对应科目的科目代码、科目名称、借方发生额、贷方发生额。(????) select a.iperiod,a.csign ,a.ino_id,a.ccode,b.ccode_name,a.md,a.mc

from GL_accvouch a join code b on a.ccode=b.ccode where a.ccode_equal like '%,101%' or a.ccode_equal like '101%' order by a.iperiod,a.csign ,a.ino_id,a.ccode

select a.ccode 科目代码,ccode_name 科目名称,SUM(md) 借方发生额,SUM(mc) 贷方发生额 from GL_accvouch a join code b on a.ccode=b.ccode

where ccode_equal like '%,101%' or ccode_equal like '101%' group by a.ccode,ccode_name

/*第二算法 赊销算法,借方一个科目,贷方一个科目。如借 应收账款/票据 贷:主营业务收入/产品销售收入 查凭证比查记录多张表。*/

--分析:从题意看有二个条件,即凭证中要有应收科目和主营业务收入科目,所以要三张表,a 表是查询结果凭证,

--------b表设应收条件,c表设主营业务收入条件。

--例:检索出所有赊销收入明细账记录。赊销:已销售,没收到钱。 --第一种方式 可以利用产品销售收入的对应科目code_equal来完成 select * from GL_accvouch

where ccode='501' and ccode_equal like '3%' and mc<>0 order by iperiod,csign,ino_id

--第二种方式 内连接方式,求两个集合的交集运算,检查两个表中的共有内容。显示的是记录而不是凭证。 Select a.* from gl_accvouch a join gl_accvouch b

on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id

where a.ccode='501' and b.ccode='113' and a.mc<>0 order by a.iperiod,a.csign,a.ino_id

--例:检索出所有赊销收入明细账凭证。或查找各月赊销凭证 --第一种方式 两表连接

select a.* from GL_accvouch a join GL_accvouch b

on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id where b.ccode='501' and b.ccode_equal like '3%' and b.mc<>0

- 1 -

order by a.iperiod,a.csign,a.ino_id

--第二种方式 三表连接 select a.* from GL_accvouch a

join GL_accvouch b on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id join GL_accvouch c on c.iperiod=b.iperiod and c.csign=b.csign and c.ino_id=b.ino_id where b.ccode like '501%' and c.ccode like '113%' and C.md<>0 and b.mc<>0 order by a.iperiod,a.csign,a.ino_id

--例:查找各月赊销收入总额

select a.iperiod 期间,SUM(a.mc) 收入总额 from GL_accvouch a

join GL_accvouch b on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id where a.ccode like '501%' and b.ccode like '113%' and b.md<>0 and a.mc<>0 group by a.iperiod

select iperiod ,SUM(mc) 收入总额 from GL_accvouch where ccode ='501' and ccode_equal like '3%' group by iperiod

--例:查找各月现销记录 select a.* from GL_accvouch a

join GL_accvouch b on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id where a.ccode like '101%' and b.ccode like '501%' and a.md<>0

select * from GL_accvouch a

where a.ccode ='101' and a.ccode_equal like 'P1%' and md<>0

--例:查找各月现销凭证 select a.* from GL_accvouch a

join GL_accvouch b on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id join GL_accvouch c on c.iperiod=b.iperiod and c.csign=b.csign and c.ino_id=b.ino_id

where b.ccode like '501%' and (c.ccode like '101%' or c.ccode like '102%') and C.md<>0 and b.mc<>0

--例:查找各月现销收入,分析:统计各月通过现结方式的现金收入。 select a.iperiod 期间,SUM(a.md) 收入 from GL_accvouch a

join GL_accvouch b on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id

where (a.ccode like '101%' or a.ccode like '102%') and b.ccode like '501%' and a.md<>0 and b.mc<>0 group by a.iperiod

--例:计算各月收回的销售欠款(应收账款)累计发生额。分析:应收账款是113,何谓收回,即113在贷方,借方应为101、102

select a.iperiod 期间,a.ccode,sum(a.mc) mc,SUM(a.md) md from GL_accvouch a

- 2 -

join GL_accvouch b on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id where (a.ccode like '101%' or a.ccode like '102%') and b.ccode like '113%' and a.md<>0 group by a.iperiod,a.ccode

--例:计算各月收回的销售欠款(应收账款)凭证。分解条件:此凭证借方应为现金或银行存款,贷方为113,要查找凭证

select a.* from GL_accvouch a join gl_accvouch b

on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id

join GL_accvouch c on c.iperiod=b.iperiod and c.csign=b.csign and c.ino_id=b.ino_id

where (b.ccode like '101%' or b.ccode like '102%') and b.md<>0 and c.ccode like '113%' and c.mc<>0 order by a.iperiod,a.csign,a.ino_id

select a.* from GL_accvouch a join GL_accvouch b

on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id where (b.ccode like '101%' or b.ccode like '102%') and b.md<>0

and (b.ccode_equal like '113%' or b.ccode_equal like '%,113%')

/*第三算法 登记一个科目,末登记一个科目的算法。使用外连接left(right) join。

实现两个集合的差集运算。找出一个集合中存在而另一个集合不存在的内容*/ --例:检查所有确认收入时,未同时提取应交税金的销售收入明细账记录。

------分析:先查询凭证中有主营业务收入,再左连接所有提取了应交税金的记录,而右表中为空的即为未提取应交税金的记录。 select a.*

from (select * from GL_accvouch where ccode like '501%' and mc<>0) a

left join (select * from GL_accvouch where ccode like '221%' and mc<>0) b on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id where b.iperiod is null

select a.* from GL_accvouch a left join

GL_accvouch b on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id and b.ccode like '221%' and b.mc<>0 where a.ccode like '501%' and b.iperiod is null and a.mc<>0

--第一个视图,获取所有有501主营业务收入的记录 create view a_1 as

select * from GL_accvouch where ccode like '501%' and mc<>0

--第二个视力,获取所有有221%提取税金的记录 create view a_2

as select * from GL_accvouch where ccode like '221%' and mc<>0

--最后,一视图左连接二视图,检查右边记录为空的所有记录,即为确认收入时未同时提取应交税金。 create view a_3 as

select a.* from a_1 a

- 3 -

left join a_2 b on a.iperiod =b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id where b.iperiod is null order by a.iperiod,a.csign,a.ino_id

drop view a_1,a_2

--例:检查漏缴税款的凭证

------分析用有主营业务收入的a表(子查询)作查询结果凭证,再与有提取税金的B表(子查询)进行左连接,右为空的即为所求。

select a.* from GL_accvouch a join (select a.*

from (select * from GL_accvouch where ccode like '501%' and mc<>0) a

left join (select * from GL_accvouch where ccode like '221%' and mc<>0) b on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id where b.iperiod is null) b

on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id

select a.* from GL_accvouch a join (

select a.* from GL_accvouch a left join GL_accvouch b

on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id and b.ccode like '221%' and b.mc<>0 where a.ccode like '501%' and a.mc<>0 and b.iperiod is null) b on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id

--在上题的基础上,将凭证表与视图a_3用join连接,而视图a_3中的记录的所在凭证即为漏缴税款的凭证 select a.*

from GL_accvouch a

join a_3 b on a.iperiod=b.iperiod and a.csign=b.csign and a.ino_id=b.ino_id order by a.iperiod,a.csign,a.ino_id

drop view a_3

/*第四算法 数据分层算法*/

--利用分组和求和、计数函数实现分层。三种情况:0到最大值分层;正的最小值到最大值分层;按金额范围分层。

--(一)从0到最大值分层。分层:(1)统计业务发生额的最大值、最小值,分别汇总金额和数量。分层的关键是找出层宽

--(2)使用ceiling取整函数进行分层分组汇总,正数“进一法”取整,负数“去尾法”取整。 -----实际上ceiling函数是返回大于或等于所给数值的最小整数。且注:5/2=2,5/2.0=2.5

--例 将主营业务收入明细账(501科目)记录从0开始到最大值分10层,统计每层业务笔数、金额,以及占总业务笔数、金额的比率。

select MAX(mc) 最大值,MAX(mc)/10 层宽,COUNT(*) 数量合计,SUM(mc) 金额合计 from GL_accvouch where ccode like '501%' and mc<>0

select cast(CEILING(mc/40800.00) as int) 层级,COUNT(*) 业务笔数,

- 4 -

cast(COUNT(*)/27.00 as numeric(4,2)) 数量比率,sum(mc) 业务金额合计,cast(sum(mc)/4733700.00 as numeric(4,4)) 金额比率

from GL_accvouch where ccode like '501%' and mc<>0 group by CEILING(mc/40800.00)

--(二)从正的最小值到最大值分层

--例 将主营业务收入明细账(501科目)记录从正的最小值开始到最大值分10层,层数=ceiling(发生额-最小值)/层宽

--统计每层业务笔数、金额,以及占总业务笔数、金额的比率。必须要做最小值的判断,使层数的开始为1。 select MAX(mc) 最大值,Min(mc) 最小值,(MAX(mc)-MIN(mc))/10 层宽,COUNT(*) 数量合计,SUM(mc) 金额合计 from GL_accvouch

where ccode like '501%' and mc<>0

select CEILING(case when mc=6000 then 1 else (mc-6000)/40200.00 end) 层级,COUNT(*) 业务笔数,count(*)/27.00 数量占比,

SUM(mc) 业务金额合计,SUM(mc)/4733700.00 金额占比 from GL_accvouch

where ccode like '501%' and mc<>0

group by CEILING(case when mc=6000 then 1 else (mc-6000)/40200.00 end)

--(三)按金额范围分层。

--例 将主营业务收入明细账(501科目)记录分为4层,包括2万元以下,2万--3万元,3万--4万元,4万元以上。

--统计每层业务笔数、金额,以及占总业务笔数、金额的比率。

--分析:首先统计每笔业务所属的区间,按区间确定层级增加“层级”列。然后再按要求进行统计。 select COUNT(*) zsl,SUM(mc) zje from GL_accvouch where ccode like '501%' and mc<>0

select 层级,COUNT(*) 业务笔数,count(*)/27.00 数量占比,SUM(mc) 业务金额合计,SUM(mc)/4733700.00 金额占比

from (select 层级=

case when mc<20000 then 1

when mc between 20000 and 30000 then 2 when mc between 30000 and 40000 then 3 when mc>40000 then 4 end,*

from GL_accvouch where ccode like '501%' and mc<>0) a group by 层级

/*第五算法 整理科目的算法*/

--例:从凭证表查询获得以下内容(期间、凭证类型、凭证号、摘要、科目代码、借贷方向、金额),利用CASE语句。

select iperiod 期间,csign 凭证类型,ino_id 凭证号,a.cdigest 摘要,a.ccode 科目代码,b.ccode_name 科目名称, case when md<>0 then '借' when mc<>0 then '贷' end 借贷方向, case when md<>0 then md when mc<>0 then mc end 金额 from GL_accvouch a join code b on a.ccode=b.ccode

- 5 -

--例:已知某单位科目代码级次为322。下列程序可以生成了个新的科目代码表。表中包含两个字段(科目代码、科目全称)

--分析:利用case语句进行判断。第一个表用来展示,第2表为二级科目表,第3表为三级科目表,第4表为四级科目表......

--按级次来确定需要连接几个表,如题,3个级次则要连接4张表。分别自连接,利用left构造各级次的代码表

select a.ccode 科目代码,科目全称=b.ccode_name+

case when LEN(a.ccode)>3 then '\\'+c.ccode_name else '' EnD + case when LEN(a.ccode)>5 then '\\'+d.ccode_name else '' end from code a

join code b on left(a.ccode,3)=b.ccode join code c on left(a.ccode,5)=c.ccode join code d on left(a.ccode,7)=d.ccode

/*第六算法 真实性、完整性、一致性检查的算法

分析:真实性、完整性算法类型比较多,首先看什么是真实性;什么是完整性,从老师已经讲过的内容来看, (注意,查真实性完整性,在凭证表中都指的是收入凭证,也就是在凭证表中要设条件ccode like '501%') 查找真实性就是从:关注业务的真实性,进行逆查.

凭证表->发票表->发货单 即为 gl_accvouch -----> salebillvouch-------> dispatchlist

查找完整性就是从:发货单->发票表->凭证表 即为 dispatchlist---->salebillvouch ------> gl_accvouch

--例:审计人员检查销售发票所列商品的品名、数量、金额与发货单中所列商品的品名、数量、金额是否一致。 分析:全连接full join。在不确定两个集合的关系时,可以使用全连接。包含了两个集合的所有元素。

通常会将同一张发票、发货单的主子表连接起来。按品名等分组。在左连接、右连接、全连接时,如 where 条件需要作比较判断时,需用isnull函数确定数据的准确性、完整性。*/ select * from (

select a.cSBVCode,cInvCode,SUM(b.iQuantity) sl,SUM (iNatSum ) je from SaleBillVouch a join SaleBillVouchs b on a.SBVID=b.SBVID group by a.cSBVCode,cInvCode) a full join

/*第九算法 时间比较的算法(时间间隔函数)*/

--例:检查每笔业务从发货到记账凭证制单之间相差天数,结果按相差天数降序排列。

--分析:据题意,是要比较发货日期与凭证制单日期的间隔,则需要使用凭证表gl_accvouch与发货表dipatchlist, --而两表不能直接连接,需通过销售主表salebillvouch作为中间表才能连接。

--分别使用连接关键字:发货-->销售sbvid(销售发票号) 销售-->凭证 cVouchType-->coutbillSign cSBVCode-->coutId

--如存在重复记录,则使用distinct去重。日期间隔函数datediff()

select distinct c.iperiod 期间,c.csign 凭证类型,c.ino_id 凭证号,a.dDate 发货日期,c.dbill_date 制单日期, DATEDIFF(D,a.dDate,c.dbill_date) 间隔天数
