所以我想在我的數據庫中使用一個表來填充一個html表格。讓我們稱之爲「商業」，其中一列稱爲「id」。 我想使用WHERE。我 例如類似..在MySQL中使用PHP的DataTables：如何修改mysql查詢？
SELECT * all FROM business WHERE id=4.
我需要修改$ sWhere嗎？
這是我用於服務器端處理的代碼。

歡迎堆棧溢出！請不要使用'mysql_ *'函數來編寫新的代碼。他們不再被維護，社區已經開始[棄用流程]（http://news.php.net/php.internals/53799）。看到[紅色框]（http://uk.php.net/manual/en/function.mysql-connect.php）？相反，您應該瞭解[準備好的陳述]（http://en.wikipedia.org/wiki/Prepared_statement）並使用[PDO]（http://php.net/pdo）或[MySQLi]（http：// php.net/mysqli）。如果你選擇PDO [這裏是一個很好的教程]（http://wiki.hashphp.org/PDO_Tutorial_for_MySQL_Developers）。 – War10ck 2013-03-06 14:32:42

沒問題的朋友。快樂的編碼！ – War10ck 2013-03-06 14:37:15
