Question

I have column in mysql DB which contains serialized data (used PHP JSON encode to serialize them).

Here is an example:

{“name”:”Group ltd”,”email”:”[e-mail]”,”auth”:”Andrey Ucholnik”}

Is there a built in function in mysql to extract these values without PHP ?
I mean to build query that will unserialize data.

Of course its possible to use combination of LOCATE and SUBSTR function to do that but I prefer something built in if possible.

There is no build in function in MySQL but by using small code in PHP you can easily do it as under:

<?php
    $json = '{{"generated": "2010-02-26T22:26:03.156866   blahblahblah   ": null, "thumbnail_url": "http://thumbs.mochiads.com/c/g/tetword-pro/_thumb_100x100.jpg", "screen4_url": "http://thumbs.mochiads.com/c/g/tetword-pro/screen4.png", "leaderboard_enabled": true, "resolution": "600x550", "width": 600}]}}';
    $out = json_decode($json, true);
    foreach($out["games"] as $game) {
        $name = addslashes($game[name]);
        $description = addslashes($game[description]);
        //Here you can use your mysql_insert code
        mysql_query("INSERT INTO games (name, description) VALUES('$name', '$description')") or die (mysql_error());
    } 
?>
