Provides a convenient object syntax to build SQL queries. Compiles the queries to an SQL text with values for binding.
Doesn't perform queries to database.
```php
$query = (new Query)
->from('posts')
->where('level', '>', 3)
->whereIn('category_id', function ($query) {
$query
->addSelect('id')
->from('categories')
->where('categories.name', 'Interesting');
})
->where(new Raw('MONTH(date)'), 4)
->orderBy('date', 'desc')
->limit(10);
$prefixer = new TablePrefixer('demo_');
$grammar = new MySQLGrammar();
$compiled = $grammar->compile($query->apply($prefixer));
echo $compiled->getSQL();
/*
SELECT *
FROM `demo_posts`
WHERE
`level` > ? AND
`category_id` IN (
SELECT `id`
FROM `demo_categories`
WHERE `demo_categories`.`name` = ?
) AND
(MONTH(date)) = ?
ORDER BY `date` DESC
LIMIT ?
*/
echo $compiled->getBindings();
/*
[3, 'Interesting', 4, 10]
*/
```
To perform compiled queries to a database, use a database connector like [PDO](http://php.net/manual/en/book.pdo.php),
[MicroDB](https://github.com/Finesse/MicroDB) or [DBAL](http://www.doctrine-project.org/projects/dbal.html) or use
a ready database abstraction like [MiniDB](https://github.com/Finesse/MiniDB) or
[Wired](https://github.com/Finesse/Wired).
Key features:
* The builder has a single responsibility: build SQL.
* Designed for further extension. You may build a database tool or an ORM on top of it without major problems.
Examples will come soon.
* Very flexible. You can pass a [raw SQL or a subquery](#raw-sql-and-subqueries) almost everywhere (see the PHPDoc
comments in the code to know where you can pass them).
* Smart table prefixes which consider table aliases (don't work in raw expressions).
* All the values go to bindings, even from subqueries.
* No dependencies. Requires only PHP ≥ 7.
Supported SQL dialects:
* MySQL
* SQLite
* ~~SQL Server~~ (not fully supported)
* Maybe any other, didn't test it
If you need a dialect support please extend the `CommonGrammar` class and make a pull request.
