RedSQL
, (*1)
RedSQL is a database agnostic helper for RedBean delivered as a plugin.
It's a tiny, fun and predictable DSL to create SQL queries in a programmatic way., (*2)
Features
- Express syntax
- Dynamic API: available methods are just a mirror of your table (bean) structure.
- Programmatic: avoid nasty string manipulations to achieve dynamic SQL construction.
- Database agnostic: SQL inconsistencies across databases (aka Oracle) like LIMIT and OFFSET are gracefully normalized.
- Lazy field loading: restrict wich fields you want to select.
- Still looks like SQL
Installation
With Composer
{
"require": {
"redsql/redsql": "~1.0"
}
}
Or just use your terminal: composer require redsql/redsql:~1.0
:8ball:, (*3)
Phar (single file)
For the folks that are not using composer yet (why u no?) you can download
redsql.phar
single distribution file and include it on your project:, (*4)
include 'path/to/redsql.phar';
Usage
RedSQL public API is ~~awsome~~ fluid and completely achieved with PHP ~~wizardry~~ magic.
So, given the following table structure:, (*5)
, (*6)
Express syntax:, (*7)
$projects =
R::redsql('project')
->name('like', '%project x')
->priority('>', 5)
->created_at('between', [$time1, $time2])
->find($limit, $offset);
// parses to:
SELECT * FROM `project`
WHERE `name` LIKE ?
AND `priority` > ?
AND `created_at` BETWEEN ? AND ?
LIMIT ? OFFSET ?
+ Syntatic sugar:, (*8)
$projects =
R::redsql('project')
->name('like', '%secret%')->AND->priority('>', 9)
->OR
->OPEN
->code('in', [007, 51])
->AND->NOT->created_at('between', [$time1, $time2])
->CLOSE
->find($limit, $offset)
// parses to:
SELECT * FROM `project`
WHERE `name` LIKE ?
AND `priority` > ?
OR (
`code` IN (?,?)
AND NOT `created_at` BETWEEN ? AND ?
)
LIMIT ? OFFSET ?
Select specific fields:, (*9)
$projects = R::redsql('project', ['name', 'description'])->find($limit, $offset);
// parses to:
SELECT `name`, `description` FROM `project` LIMIT ? OFFSET ?
- Houston, we got Oracle! - No problem., (*10)
$projects = R::redsql('project', ['name', 'description'])->find($limit, $offset);
// parses to:
SELECT * FROM (
SELECT VIRTUAL.*, ROWNUM ROWOFFSET FROM (
SELECT `name`, `description` FROM `project`
) VIRTUAL
) WHERE ROWNUM <= ? AND ROWOFFSET >= ?
Public API
R::redsql($table, array $fields = [])
Returns a configured RedBeanPHP\Plugins\RedSql\Finder
instance restricted to a given entity:, (*11)
$project_query = R::redsql('project');
New conditions can be queued lazily:, (*12)
$project_query->created_at('>', '2014-04-03 00:00:00');
$projects = $project_query->find(); // finally reach database
Finder can restrict what fields should be queried:, (*13)
$project_query = R::redsql('project', ['name', 'priority']);
//
SELECT `id`, `name`, `priority` FROM `project`
find($limit = null, $offset = null)
Fetches an array of RedBean_OODBBean
instances from database:, (*14)
$projects = R::redsql('project')->NOT->priority(3)->find();
//
SELECT * FROM `project` WHERE NOT `priority` = ?
findFirst()
Applies LIMIT
and ORDER BY ASC
statements and fetches a single RedBean_OODBBean
instance from database:, (*15)
$project = R::redsql('project')->NOT->priority(3)->findFirst();
//
SELECT * FROM `project` WHERE NOT `priority` = ? ORDER BY `id` ASC LIMIT 1 OFFSET ?
findLast()
Applies LIMIT
and ORDER BY DESC
statements and fetches a single RedBean_OODBBean
instance from database:, (*16)
$project = R::redsql('project')->NOT->priority(3)->findLast();
//
SELECT * FROM `project` WHERE NOT `priority` = ? ORDER BY `id` DESC LIMIT 1 OFFSET ?
findAlike(array $conditions, $limit = null, $offset = null)
Applies a batch of conditions and fetches an array of RedBean_OODBBean
instances from database:, (*17)
$projects = R::redsql('project')->findAlike([
'name' => 'X Project',
'description' => '%secret%',
'priority' => [1, 2, 3]
], $limit, $offset
);
//
SELECT *
FROM `project`
WHERE `name` = ?
AND `description` LIKE ?
AND `priority` IN (?,?,?)
LIMIT ? OFFSET ?
toString()
Finders RedBeanPHP\Plugins\RedSql\Finder
can be converted to plain SQL using (string)
casting or toString
method:, (*18)
$project_finder = R::redsql('project');
echo (string) $project_finder;
$project_finder->NOT->priority(3);
echo $project_finder->toString();
// >
SELECT * FROM `project`
SELECT * FROM `project` WHERE NOT `priority` = ?
Database Support
If build badge is green it means RedSql latest version is working on:, (*19)
- Oracle
- Postgre
- MySQL
- SQLite
- CUBRID
- ~~MSSQL Server~~ (as soon as RedBean supports it)
Roadmap
- [ ] RedBean ~4.0 support
- [ ] Beans collection
- [ ] Relationships
- [x] Single file release (phar)
