Yorch Ponce

This package can execute queries on MySQL, SQLServer, PostgreSQL and ODBC.

There is a factory class that can instantiate driver classes that can access different database types.

The same class can also execute prepared queries and return results in arrays by calling the driver classes.

Abstract Class to manage RDBMS (MySQL, MSSQLServer, ODBC, PostgreSQL) connections

Example

<?php
require 'vendor/autoload.php';

require_once('MyDb.class.php');

// Mysql Example
$provider = 'MySQLDb';
$hostname = '';
$username = '';
$password = '';
$dbname = '';

$dbMySQL = MyDb::getInstance($provider, $hostname, $username, $password, $dbname, 3306);

$query = sprintf("SELECT 1 AS %s", $dbMySQL->escape($provider));

// Associate
print_r($dbMySQL->executeCommand($query));

// Enumerate
print_r($dbMySQL->executeCommand($query, null, MyDb::ENUM));

$dbMySQL = null;

// SQL Server Example
$provider = 'SQLServerDb';
$hostname = '';
$username = '';
$password = '';
$dbname = '';

$dbSQLServer = MyDb::getInstance($provider, $hostname, $username, $password, $dbname, 1433);

$query = sprintf("SELECT 1 AS %s", $dbSQLServer->escape($provider));

// Associate
print_r($dbSQLServer->executeCommand($query));

// Enumerate
print_r($dbSQLServer->executeCommand($query, null, MyDb::ENUM));

$dbSQLServer = null;

// ODBC Example
$provider = 'ODBCDb';
$hostname = 'localhost';
$username = '';
$password = '';
$dbname = 'ODBCDSN'; // ODBC Data Source Name

$dbODBC = MyDb::getInstance($provider, $hostname, $username, $password, $dbname, 1);

$query = sprintf("SELECT 1 AS %s", $dbODBC->escape($provider));

// Associate
print_r($dbODBC->executeCommand($query));

// Enumerate
print_r($dbODBC->executeCommand($query, null, MyDb::ENUM));

$dbODBC = null;

// PostgreSQL Example
$provider = 'PostgreSQLDb';
$hostname = '';
$username = '';
$password = '';
$dbname = '';

$dbPgSQL = MyDb::getInstance($provider, $hostname, $username, $password, $dbname, 5432);

$query = sprintf("SELECT 1 AS %s", $dbPgSQL->escape($provider));

// Associate
print_r($dbPgSQL->executeCommand($query));

// Enumerate
print_r($dbPgSQL->executeCommand($query, null, MyDb::ENUM));

$dbPgSQL = null;

// Mysql Singleton Example
$provider = 'MySQLDb';
$hostname = '';
$username = '';
$password = '';
$dbname = '';

$db = MyDb::getConnection($provider, $hostname, $username, $password, $dbname, 3306);

$query = sprintf("SELECT 1 AS %s", $dbMySQL->escape($provider));

// Associate
print_r($dbMySQL->executeCommand($query));

// Clone in not permitted

Example

// Mysql Example
$provider = 'MySQLDb';
$hostname = '';
$username = '';
$password = '';
$dbname   = '';

$dbMySQL = MyDb::getInstance($provider, $hostname, $username, $password, $dbname, 3306);  

$query = sprintf("SELECT 1 AS %s", $dbMySQL->escape($provider));

// Associate
print_r($dbMySQL->executeCommand($query));  

// Enumerate
print_r($dbMySQL->executeCommand($query, null, MyDb::ENUM));  

$dbMySQL = null;

Notes

The SQL Server connection only works in MS Windows.

For PostgreSQL the parameters in SQL Query must be $#. example: 'SELECT * FROM MYTABLE WHERE ID = $1 AND DESCRIPTION = $2'

For ODBC connection, if the query insert uses ? parameters throw this error (COUNT field incorrect or syntax error).

Sorry, my english is bad :(.
