將特定表格列導出到Excel

Question

我想從我的SQL數據庫表格導出Excel（.xls）的特定列數據（即Ticket＃，Company/Customer Name，Issue Subject，Date Closed）代碼編寫，但它導出我的整個數據庫表。 （見代碼下面）

需要被導出的特定列數據：

• ticketID
• 名稱
• 公司
• 受試者
• 關閉

也就是有任何方式來添加一個功能，只能導出一個特定的範圍（即。，日期範圍從2012年10月1日至2012年10月31日）？

更改SQL：

//DEFINE SQL QUERY: 
//edit this to suit your needs 
$sql = "Select ticketID, name, company, subject, closed from $DB_TBLName";
