Super MySQL is an easy-to-use powerful SQL query builder.
- PHP 5.6+
- MySQL
- PDO MySQL extension
Let’s have a table “users” with 5 columns: uid, username, password, sign_up_time and nickname
<?php
include "smysql.php";
//Connect with new Smysql($host, $user, $password[, $database])
$smysql = new Smysql("localhost", "root", "root", "db");
//To execute raw SQL query use $smysql->q($q[, $a]), FETCH_ALL returns an array of rows, FETCH_OBJECT and FETCH_ARRAY return one row per call
$smysql->q("SELECT * FROM users")->fetch(SMQ::FETCH_ALL);
//You can use wildcards for escaping
$smysql->q("SELECT * FROM users WHERE `username`=%0 OR `nickname`=%1", [$name, $nick])->fetch();
//You can use queries as methods
$smysql->getUser = "SELECT * FROM users WHERE `username`=%0 OR `nickname`=%1";
$user = $smysql->getUser($name, $nick)->fetch();
//For simple requests use $smysql->read($table[, $flags]) or $smysql->read($table, $cond[, $flags])
//Read function uses FETCH_SMART as default (FETCH_OBJECT for one row, FETCH_ALL for more), so you need to use the FETCH_ALL flag to return an array even when there is only one result
$users = $smysql->read("users", SMQ::FETCH_ALL);
$user = $smysql->read("users", ['uid' => $id]);
//You can use more conditions
$user = $smysql->read("users", ['username' => $name, 'password' => $pass]);
//You can use the COND_OR flag for OR operator instead of AND
$user = $smysql->read("users", ['username' => $name, 'nickname' => $nick], SMQ::FETCH_ALL | SMQ::COND_OR)[0];
//You can use custom conditions
$users = $smyslq->read("users", "`sign_up_time` > " . bcsub(time(), 3600));
//You can use more of them
$users = $smyslq->read("users", ["`sign_up_time` > " . bcsub(time(), 3600), "`nickname` IS NOT NULL"], SMQ::FETCH_ALL);
//For more complicated requests use $smysql->select($table[, $order[, $cols[, $limit[, $flags]]]]), you can use array keys for aliases
$users = $smysql->select("users", "sign_up_time", ['id' => "uid", 'name' => "username", "sign_up_time", "nickname"], NULL, SMQ::ORDER_DESC)->fetch(SMQ::FETCH_ALL);
//Or $smysql->selectWhere($table, $cond[, $order[, $cols[, $limit[, $flags]]]])
$user = $smysql->selectWhere("users", ['uid' => $id], "name", ['id' => "uid", 'name' => "username", "sign_up_time", 'nick' => "nickname"])->fetch();
//To quickl
8000
y display tables use ->dump()
$smysql->select("users")->dump();
//Insert with $smysql->insert($table, $values[, $flags])
$smysql->insert("users", [$id, $name, $pass, time(), NULL]);
//You can use array keys as col names
$smysql->insert("users", ['username' => $name, 'password' => $pass, 'sign_up_time' => time()]);
//You can use INSERT_RETURN_ID flag for returning the first auto increment col value (depends on the database type)
$id = $smysql->insert("users", ['username' => $name, 'password' => $pass, 'sign_up_time' => time()], SMQ::INSERT_RETURN_ID);
//Use $smysql->update($table, $cond, $values[, $flags]) to update rows
$smysql->update("users", ['id' => $id], ['nickname' => $nick]);
//You can delete rows with $smysql->delete($table, $cond[, $flags])
$smysql->delete("users", ['id' => $id]);
//Use $smysql->truncate($table[, $flags]) to delete all rows in a table
$smysql->truncate("users");
?>Here is list of all Super-MySQL flags:
- ORDER_ASC
- ORDER_DESC
- JOIN_INNER
- JOIN_LEFT
- JOIN_RIGHT
- JOIN_FULL
- INSERT_RETURN_ID
- COND_AND
- COND_OR
- FETCH_OBJECT
- FETCH_ARRAY
- FETCH_ALL
- FETCH_SMART
- NO_ERROR
<?php
//To use the same database in more projects you can extend the Smysql class
class mySmysql extends Smysql {
protected $host = "localhost";
protected $user = "root";
protected $password = "root";
protected $db = "db"; //Optional
};
//And then create an instance
$smysql = new mySmysql();
//If $db is not set, you can set it afterwards
$smysql->changeDb("newDB");
//Join
//Use $smysql->selectJoin($table, $join, $on[, $order[, $cols[, $limit[, $flags]]]]) to execute a JOIN command
$result = $smysql->selectJoin("users", "messages", ['from_user' => 'uid'], "time", "*", 5, SMQ::ORDER_DESC)->fetch(SMQ::FETCH_ALL);
//Use JOIN_LEFT, JOIN_RIGHT and JOIN_FULL flags to other types of JOIN
//To combine JOIN and WHERE use $smysql->selectJoinWhere($table, $join, $on, $cond[, $order[, $cols[, $limit[, $flags]]]])
$result = $smysql->selectJoinWhere("users", "messages", ['from_user' => 'uid'], ['from_user' => $uid])->fetch(SMQ::FETCH_ALL);
