Экспорт mySQL в Excel с датами в желаемом формате

Question

Я экспортирую данные из базы данных mySQL в лист Excel. Все работает только для того, чтобы формат даты был в этом формате: m/d/Y. В настоящее время в mySQl есть формат yyyy-mm-dd. Мои столбцы даты - lastvisit, cdate и ddate. Любые примеры и помощь оцениваются.

Это мой рабочий код PHP:

<?PHP 

//EDIT YOUR MySQL Connection Info: 
$DB_Server = "localhost";  //your MySQL Server 
$DB_Username = "root";     //your MySQL User Name 
$DB_Password = "ase";    //your MySQL Password 
$DB_DBName = "fert";    //your MySQL Database Name 
$DB_TBLName = "fert";    //your MySQL Table Name 

//$DB_TBLName, $DB_DBName, may also be commented out & passed to the browser 
//as parameters in a query string, so that this code may be easily reused for 
//any MySQL table or any MySQL database on your server 

//DEFINE SQL QUERY: 
//edit this to suit your needs 


$sql = "Select id, name, id_continent, lastvisit,cdate, ddate,notes from $DB_TBLName ORDER BY ddate ASC"; 
//Optional: print out title to top of Excel or Word file with Timestamp 
//for when file was generated: 
//set $Use_Titel = 1 to generate title, 0 not to use title 
$Use_Title = 0; 
//define date for title: EDIT this to create the time-format you need 
$now_date = DATE('m-d-Y H:i'); 
//define title for .doc or .xls file: EDIT this if you want 
$title = "Dump For Table $DB_TBLName from Database $DB_DBName on $now_date"; 
/* 

Leave the connection info below as it is: 
just edit the above. 

(Editing of code past this point recommended only for advanced users.) 
*/ 
//create MySQL connection 
$Connect = @MYSQL_CONNECT($DB_Server, $DB_Username, $DB_Password) 
    or DIE("Couldn't connect to MySQL:<br>" . MYSQL_ERROR() . "<br>" . MYSQL_ERRNO()); 
//select database 
$Db = @MYSQL_SELECT_DB($DB_DBName, $Connect)

//execute query

Answer 1

Используйте MySQL DATE_FORMAT function в ваш выбор:

select ....DATE_FORMAT(lastvisit, '%m/%d/%Y') as lastvisit, DATE_FORMAT(ddate, '%m/%d/%Y') as ddate .... 

и так далее.

Answer 2

Изменение SQL для:

Select id, name, id_continent, date_format(lastvisit,'%m/%d/%Y'),date_format(cdate,'%m/%d/%Y'), date_format(ddate,'%m/%d/%Y'),notes from $DB_TBLName ORDER BY ddate ASC";
