Demo

Online demo

Live demo and free usage is available here.

Get Started

Install by a manual download:

Download the repository and install required packages by composer.json.

Packagist

You can also install it from packagist by running the following command:

composer require rexshijaku/sql-to-ci-builder

Usage

Simple example

<?php

use RexShijaku\SQLToCIBuilder\SQLToCIBuilder;

require_once dirname(__FILE__) . './vendor/autoload.php';

$options = array('civ' => 4);
$converter = new SQLToCIBuilder($options);

$sql = "SELECT COUNT(*) FROM members";
echo $converter->convert($sql);

This will produce the following result:

$this->db->countAll('members');

A more complex example :

$sql = "SELECT * FROM members WHERE age > 30 
                            OR (name LIKE 'J%' OR (surname='P' AND name IS NOT NULL)) AND AGE !=30";
$converter->convert($sql);

and this will generate the result below :

$db->table('members')
 ->where('age >',30)
 ->orGroupStart()
     ->like('name','J','after')
     ->orGroupStart()
         ->where('surname','P')
         ->where('name !=',null)
     ->groupEnd()
 ->groupEnd()
 ->where('AGE !=',30)
 ->get();

Notice

In both of these examples Codeigniter 4 was used. If you need to change it, or get more comprehensive understanding of provided options then see the following section of Options. There are dozens of examples for every use case explained in the Query Builder documentation for both version 3 and version 4 located in their respecitve folders inside the examples folder.

Options

Some important options are briefly explained below:

How does it works ?

SQL-To-CI-Builder is built on top of PHP-SQL-Parser. While PHP-SQL-Parser is responsible for parsing the given SQL Query as input. The result of the PHP-SQL-Parser is the input of SQL-To-CI-Builder.

The structure has three main parts :

1. Extractors classes - which help to pull out SQL Query parts in a way which are more understandable and processable by Builders.
2. Builder classes - which help to construct Query Builder methods.
3. Creator - which orchestrates the process between Extractors and Builders in order to produce parts of Query Builder.

Known issues

• It is not tested in all cases. They should be added.
• Poor error handling.

Thank you

All contributors who created and are continuously improving PHP-SQL-Parser, without it, this project would be much harder to be realized.
