原因：违反了PRIMARY KEY 约束'PK__仓库__530C599C7F60ED59'。不能在对象'yaojinhong仓库' 中插入重复键。语句已终止。

insert into yaojinhong职工 values('ZG000011','QW0009',3000)

原因：仓库号列参照仓库表的仓库号，此时在仓库表中找不到仓库号为QW0009的仓库。INSERT 语句与FOREIGN KEY 约束"FK__职工__仓库号__0AD2A005"冲突。该冲突发生于数据库"实验"，表"yaojinhong仓库", column '仓库号'。

insert into yaojinhong仓库 values('QW0006','天津',30)

原因：在定义时，面积要大于等于50，这里面积为30，明显违反了用户定义完整性

删除 *** 作失败。因为有职工参照了干记录

delete yaojinhong供应商 where 供应商号='S002'

实验5

一

(1) 基于单个表按投影 *** 作定义视图。

create view yaojinhong仓库视图 as select from yaojinhong仓库

(2) 基于单个表按选择 *** 作定义视图。

create view yaojinhong仓库视图1 as select from yaojinhong仓库 where 城市='广州'

(3) 基于单个表按选择和投影 *** 作定义视图。

create view yaojinhong仓库视图2 as select 仓库号,面积 from yaojinhong仓库 where 城市='广州'

(4) 基于多个表根据连接 *** 作定义视图。

create view yaojinhong视图3 as select 职工号,城市,工资 from yaojinhong职工 join yaojinhong仓库 on 职工仓库号=仓库仓库号

(5) 基于多个表根据嵌套查询定义视图。

create view yaojinhong视图4 as select from yaojinhong仓库 where 仓库号 in

(select 仓库号 from yaojinhong职工 where 工资>4000)

(6) 定义含有虚字段的视图。

create view yaojinhong虚字段视图(仓库号,城市,面积) as select 仓库号,城市,面积2 from yaojinhong仓库

2、分别在定义的视图上设计一些查询（包括基于视图和基本表的连接或嵌套查询）。

select from yaojinhong仓库视图

select from yaojinhong仓库视图1 where 城市='广州'

select 仓库号,面积 from yaojinhong仓库视图2

select 职工号,城市,工资 from yaojinhong职工 join yaojinhong仓库视图 on 职工仓库号=仓库视图 仓库号

select from yaojinhong仓库视图 where 仓库号 in

(select 仓库号 from yaojinhong职工 where 工资>4000)

3、在不同的视图上分别设计一些插入、更新和删除 *** 作，分情况讨论哪些 *** 作可以成功完成，哪些 *** 作不能完成，并分析原因。

insert into yaojinhong仓库视图(仓库号,城市) values('QW0008','长沙')

update yaojinhong仓库视图 set 面积=650 where 仓库号='QW0008'

insert into yaojinhong仓库视图 values('QW0008','长沙',500)

update yaojinhong仓库视图 set 面积=700 where 仓库号='QW0001'

delete yaojinhong仓库视图 where 仓库号='QW0008'

delete yaojinhong仓库视图 where 仓库号='QW0008'
