## Yonna DB - ORM 库
```
Yonna是一个极其纯净的纯API-PHP框架.
database库是yonna最强大的DB-ORM
```
##
#### 如何安装
##### 可以通过composer安装：`composer require yonna/database`
##### 可以通过git下载：`git clone https://github.com/yonna-framework/database.git`
> Yonna demo：[GOTO yonna](https://github.com/yonna-framework/yonna)
### ORM
> 连贯写法，全解耦，autoload后随意使用
>> DB自带各种分析优化，所以不再需要 Model层进行优化，可专心编写你的service(scope)
```php
DB::connect() // 默认 'default'
->table('system_data')
->field('key,value')
->in('key', $key)
->one();
DB::connect('mysql')
->table('system_data')
->field('key,value')
->in('key', $key）
->one();
DB::connect('pgsql')
->schemas('default')
->table('system_data')
->field('key,value')
->in('key', $key)
->multi();
DB::connect('mssql')
->schemas('default')
->table('system_data')
->field('key,value')
->in('key', $key)
->page();
DB::connect('sqlite')
->table('system_data')
->field('key,value')
->in('key', $key)
->count();
DB::connect('redis')->set('key', 1);
DB::connect('redis')->get('key');
DB::connect('redis')->incr('key');
DB::connect('redis')->decr('key');
DB::connect('redisCo')->set('swoole', 1);
DB::connect('redisCo')->get('swoole');
DB::connect('redisCo')->incr('swoole', 1.5);
DB::connect('redisCo')->decr('swoole', 2);
```
> 终结方法
>> one() multi() page() insert() insertAll() delete() count() sum() avg() min() max()
> schemas() / table() 方法会进行一次clear，所以请放在前面
##### 局部闭包（默认）
##### 等于 ( "a" = 1 or "b" = 1 ) and( "c" = 1 or "d" = 1 or "e" = 1 )
```php
DB::connect('mysql')
->table('demo')
->equalTo('a',1)
->equalTo('b',1)
->closure('or')
->equalTo('c',1)
->equalTo('d',1)
->equalTo('e',1)
->closure('or')
->one();
```
##### 全局闭包
##### 等于 (( "a" = 1 or "b" = 1 ) or "c" = 1 or "d" = 1 or "e" = 1 )
```php
DB::connect('pgsql')
->schemas('default')
->table('demo')
->equalTo('a',1)
->equalTo('b',1)
->closure('or')
->equalTo('c',1)
->equalTo('d',1)
->equalTo('e',1)
->closure('or',true)
->one();
```
##### 插入后可以获取 lastInsertId（在无序列表中自动获取可能会产生严重的错误）
```php
try {
DB::connect('pgsql')->schemas('default')->table('data')->insert(['data' => 1]);
$lastId = DB::lastInsertId();
} catch (\Exception $e) {
return $this->error($e->getMessage());
}
```
##### 如果你只是想获取sql而不请求数据库，请使用 fetchSql()
```php
DB::connect()->table('demo')->equalTo('status',1)->fetchSql()->multi();
```
### JSON（pgsql）
#### 搜索例子1
```sql
select * from "default".system_data where (data#>>'{project_name,name}')::text like '%系统%';
```
#### 搜索例子2
```sql
select * from "default".system_data where ("data"->'server_pre_alert_limit'->'value')::text::int > 5;
```
### 前端json搜索语法
`
{project_name,name} % #TT || (({project_name,name} % #系统 || {project_name,name} != #xxx) && {server_pre_alert_limit,value} > #1 && ({server_pre_alert_limit,value} > #0 || {server_pre_alert_limit,value} < #100000000))
`
```
[ n ] isNull
{?,?,?} n #
[ !n ] isNotNull
{?,?,?} !n #
[ % ] like
{?,?,?} % #???
[ !% ] notLike
{?,?,?} !% #???
[ = ] equalTo
{?,?,?} = #???
[ > ] greaterThan
{?,?,?} > #???
[ < ] lessThan
{?,?,?} < #???
[ >= ] greaterThanOrEqualTo
{?,?,?} >= #???
[ <= ] lessThanOrEqualTo
{?,?,?} <= #???
[ <> , != ] notEqualTo
{?,?,?} <> #???
{?,?,?} != #???
[ >< ] between
{?,?,?} >< #???,???
[ !>< ] notBetween
{?,?,?} !>< #???,???
[ * ] any
{?,?,?} * #???,???,???...
[ ^ ] in
{?,?,?} ^ #???,???,???...
[ !^ ] notIn
{?,?,?} !^ #???,???,???...
```
