# 删除
SmartMarket 公司的业务数据库中，有一个 orders 表，其结构主要是以下形态：
```postgresql
create table orders
(
id serial primary key,
meta jsonb default '{}'::jsonb,
content jsonb default '{}'::jsonb,
created_at timestamp default now(),
deal boolean
)
```
有一个业务系统会实时的将已经成交（deal 字段为 true）的订单数据转储，现在我们仅需要一个清理 程序，将已经成 交的数据从 orders 表删除并记录被删除的数据id。下面哪个操作是对的？
## 答案
在一个独立的定时任务中执行
```postgresql
delete
from orders
where deal
returning id;
```
并记录id
## 选项
### A
在一个独立的定时任务中执行
```postgresql
truncate orders;
```
### B
在一个独立的定时任务中执行
```postgresql
delete
from orders;
```
### C
在一个独立的定时任务中执行
```postgresql
drop table orders;
create table orders
(
id serial primary key,
meta jsonb default '{}'::jsonb,
content jsonb default '{}'::jsonb,
created_at timestamp default now(),
deal boolean
);
```
### D
建立视图
```postgresql
create view order_view as
select id, meta, content, created_at
from orders
where not deal;
```
并要求业务系统只能访问这个视图。
### E
在一个独立的定时任务中执行
```postgresql
delete
from orders
where deal;
```
并记录操作前后表中的最大 id

# 插入
现有一个表：
```postgresql
create table book(
id serial primary key ,
title text not null ,
meta jsonb default '{}'::jsonb,
price money,
isbn text not null ,
publish_at date not null
);
create unique index on book(isbn);
create index on book using gin(meta);
```
那么下列哪个选项的代码可以执行成功？
## 答案
```postgresql
insert into book(title, price, isbn, publish_at) select 'a book title', 25.4, 'xx-xxxx-xxxx', '2019-12-1'::date;
insert into book(title, price, isbn, publish_at) select 'a other book title', 25.4, 'yy-yyyy-xxxx', '2019-12-1'::date;
```
## 选项
### 唯一键冲突
```postgresql
insert into book(title, price, isbn, publish_at) select 'a book title', 25.4, 'xx-xxxx-xxxx', '2019-12-1'::date;
insert into book(title, price, isbn, publish_at) select 'a other book title', 35.4, 'xx-xxxx-xxxx', '2019-12-1'::date;
```
### 缺少必要的列
```postgresql
insert into book(price, isbn, publish_at) select 25.4, 'xx-xxxx-xxxx', '2019-12-1'::date;
insert into book(price, isbn, publish_at) select 35.4, 'yy-yyyy-xxxx', '2019-12-1'::date;
```
### 类型错误
```postgresql
insert into book(title, price, isbn, publish_at) select 'a book title', 'unknown', 'xx-xxxx-xxxx', '2019-12-1'::date;
insert into book(title, price, isbn, publish_at) select 'a other book title', 'unknown', 'xx-xxxx-xxxx', '2019-12-1'::date;
```
### 违反非空约束
```postgresql
insert into book(title, price, isbn, publish_at) select null, 'unknown', 'xx-xxxx-xxxx', '2019-12-1'::date;
insert into book(title, price, isbn, publish_at) select null, 'unknown', 'xx-xxxx-xxxx', '2019-12-1'::date;

# 更新数据
现有 employee 表如下：
```postgresql
create table employee
(
id serial primary key,
name text,
dept text,
salary money
);
```
我们希望修改销售部(dept 字段为 sale)员工 Dora Muk 的工资，将其增加 1000，返回她的工号。正确的修改语句是：
## 答案
```postgresql
update employee set salary = salary + 1000 where dept = 'sale' and name = 'Dora Muk' returning id;
```
## 选项
### 过滤条件不严谨
```postgresql
update employee set salary = salary + 1000 where name = 'Dora Muk' returning id;
```
### 没有返回员工id
```postgresql
update employee set salary = salary + 1000 where dept = 'sale' and name = 'Dora Muk';
```
### 缺少过滤条件
```postgresql
update employee set salary = salary + 1000 returning id;
```
### 错误的赋值语句
```postgresql
update employee set salary += 1000 returning id;
```
