我有一個表列「工作時間」,我想總結的所有行是這樣的:總和小時總行
08:00
02:00
03:30
Total: 13:30
這是我的SQL SELECT代碼
$sql=mysql_query("SELECT * FROM sohy_works WHERE data_raport = '$data' AND codangajat = '$codangajat' ");

你可以計算出這個樣子,
SELECT SEC_TO_TIME(SUM(your_time_field)) FROM sohy_works WHERE .....
我可以做這個「SELECT *(ALL)SEC_TO_TIME(SUM(your_time_field))從sohy_works WHERE .....? –
的從數據庫中獲取秒之和將其轉換成小時和分鐘:
$q = "SELECT SUM(TIME_TO_SEC(worked_hours)) FROM sohy_works WHERE data_raport = '$data' AND codangajat = '$codangajat'";
$result = mysql_query($q);
$sec = mysql_fetch_array($result);
$hours = floor($sec[0]/3600);
$minutes = str_pad(floor($sec[0] % 3600/60), 2, '0', STR_PAD_LEFT);
echo $hours.':'.$minutes;
編輯:
小時和分鐘可直接與SQL查詢等計算:
SELECT SEC_TO_TIME(SUM(TIME_TO_SEC(`worked_hours`))) FROM ...
是所選答案真的解決問題嗎? – Danijel
