README

This library generates type-safe PHP classes from your database tables and thus allows you to interact with your database in a complete type-safe way.

About

In traditional ORMs you write a class add specific metadata and generate based on this class your tables, this means our source code defines how a table should look. This library thinks the other way around (database first), this means you first build your database schema i.e. through a tool like doctrine migrations and then you can use this library to automatically generate all repository and model classes based on the table schema. This has the great advantage that we can generate completely typed repositories. We automatically generate a class for each row (entity) and a repository which accepts this row. This concept is not new and the Java world has i.e. jOOQ which also follows this idea. It of course means also that you need to regenerate your classes if you change your schema.

Generate

To generate the table and row classes you can either integrate the PSX\Command\GenerateCommand into your Symfony console app or you can also do this programmatically through the PSX\Sql\Generator class s.

<?php

use PSX\Sql\Generator\Generator;

$connection   = null; // a doctrine DBAL connection
$target = __DIR__;

$generator = new Generator($connection, 'Acme\\Table');
foreach ($generator->generate() as $className => $source) {
    file_put_contents($target . '/' . $className . '.php', '<?php' . "\n\n" . $source);
}

Basic usage

The following are basic examples how you can work with a generated table class.

<?php

use PSX\Sql\Condition;
use PSX\Sql\OrderBy;
use PSX\Sql\TableManager;

$connection   = null; // a doctrine DBAL connection
$tableManager = new TableManager($connection);

/** @var \PSX\Sql\Tests\Generator\SqlTableTestTable $table */
$table = $tableManager->getTable(\PSX\Sql\Tests\Generator\SqlTableTestTable::class);

// returns by default 16 entries from the table ordered by the primary column descending
$table->findAll();

// returns 12 entries starting at index 0
$table->findAll(startIndex: 0, count: 12);

// orders the entries after the column "id" descending
$table->findAll(startIndex: 0, count: 12, sortBy: 'id', sortOrder: OrderBy::DESC);

// returns all rows which match the specified title
$table->findByTitle('foo%');

// returns a row by the primary key
$table->find(1);

// returns the count of entries in the table. It is also possible to provide a condition
$table->getCount();

// creates a new row
$row = new \PSX\Sql\Tests\Generator\SqlTableTestRow();
$row->setTitle('foo');
$table->create($row);

// updates a row
$row = $table->find(1);
$row->setTitle('bar');
$table->update($row);

// deletes a row
$row = $table->find(1);
$table->delete($row);

Table

The following is an example of a generated table class.

Row

The following is an example of a generated table row.

    }
}
