Overview
----
> ### 1. Introduction
The `orm` package allows you to simplify SQL requests through php objects. You will never have to use SQL code anymore.
> ### 2. Setup
In order for the orm to work, you will ne to configure the `database` driver according to your database credentials and information.
> ### 3. Features
Query types
- Manage `SELECT` queries
- Manage `UPDATE` queries
- Manage `INSERT INTO` queries
- Manage `DELETE` queries
Specification
- Fetches the whole schema specification (foreign keys, primary keys, etc)
- Manage `SELECT *`
- Manage composite `PRIMARY KEY`
- Manage `WHERE` conditions (_=_, _<>_, _<_, _>_, _>=_, _<=_, _LIKE_, _IN_)
- Manage aggregation functions (_AVG()_, _SUM()_, _MAX()_, _MIN()_, _COUNT()_, *GROUP_CONCAT()*)
- Manage `ORDER BY` ordering
- Manage `SELECT DISTINCT` specification (_ASC_, _DESC_)
- Inserting multiple rows at once
- Automatically select the **PRIMARY KEY(S)**
- Manage joined tables
- Manage `fetch` and `fetchAll`
- Manage `NULL` keyword
- Manage booleans
- Manage inserting the `DEFAULT` value
- Manage format beautifying (numbers as numbers, same for booleans, null)
Usage
----
> ### (1) Loader
```php
<?php
require_once __ROOT__.'/autoloader.php';
use \orm\core\Table;
use \orm\core\Rows;
```
> ### (2) SELECT queries
> #### (2.1) Single Table
```php
<?php
// All matching rows
Table::get('table_name')
->select('*')
->fetch();
// First row only
Table::get('table_name')
->select('*')
->unique()
->fetch();
```
> #### (2.3) Select
```php
<?php
Table::get('table_name')
->select('field_1')
->select('field_2')
/// ...
->select('field_N')
->fetch();
```
> #### (2.4) Order by
```php
<?php
// Ascending order of the field `field_name`
Table::get('table_name')
->orderby('field_name', Rows::ORDER_ASC)
->fetch();
// Descending order of the field `field_name`
Table::get('table_name')
->orderby('field_name', Rows::ORDER_DESC)
->fetch();
```
> #### (2.5) WhereId
It will match the corresponding `PRIMARY KEY` of the table, if it is a composed key (multiple fields) instead of giving an argument, give an array for each in the order displayed in _phpmyadmin_ or you mysql viewer.
```php
<?php
// PRIMARY KEY => `id_user`
Table::get('user')
->select('*') // select all fields
->whereId(12) // if id_user is equal to 12
->fetch(); // fetch matching rows
// PRIMARY KEYS => `username` + `mail`
Table::get('user')
->select('*') // select all fields
->whereId([12, 'sample@mail.com'])
// if `id_user` is equal to 12
// AND `mail` is equal to 'sample@mail.com'
->fetch(); // fetch matching rows
```
The available condition operators are listed in the [constants](todo) section.
Note: `Rows::COND_EQUAL` is set by default if missing
> #### (2.6) Where clause
The where clause uses one of php's magic functions (__call). So the name of the method you call will contain the field of the condition. But you must use the correct case, removing '_' and setting the next character to upper case. The rest will be forced to lower case.
You can refer to the following examples:
|Field|condition|
|---|---|
|username|`whereUsername`|
|id_user|`whereIdUser`|
|aaa_bb_c_ddd|`aaaBbCDdd`|
```php
<?php
Table::get('user')
->select('*')
->whereUsername('someusername') // if username is equal to 'someusername'
->whereMail(['somemail', Rows::COND_EQUAL]) // same as previous line (explicit here)
->fetch();
```
