我有一些數據與用戶名和日期。SQL插入或更新超時循環中的大日期
有時候會有大量數據需要循環並更新sql數據庫,但數據庫超時。
有沒有更好的方法可以做到這一點,請在下面的示例代碼。
foreach($time[$re->userid][$today] as $t){
if(($re->time >= $t->in_from) && ($re->time < $t->in_to)
&& md5($t->WorkDay."_in".$re->date) != $in){//in
$tble = tools::sd("{$t->WorkDay} in");
}
if(($re->time >= $t->out_from) && ($re->time < $t->out_to)
&& md5($t->WorkDay."_out".$re->date) != $out){//out
$tble = tools::sd("{$t->WorkDay} out");
if($tble =='nout'){
$re->date2 = tools::ndate($re->date . "- 1");
}
}
if(!empty($tble)){
$q = array(
"id" => $re->userid
, "dt" => $re->date2
, "{$tble}" => $re->time
);
dump($q); // insert into sql
}
}
轉儲功能:::
function dump($d ='')
{
if(!empty($d)){
end($d);
$tble = key($d);
$d['ld'] = "{$d['dt']} {$d[$tble]}";
$r = $GLOBALS['mssqldb']->get_results("
IF NOT EXISTS (select id,ld,dt,{$tble} from clockL
WHERE id = '{$d['id']}'
AND dt ='{$d['dt']}')
INSERT INTO clockL (id,ld,dt,{$tble})
VALUES ('{$d['id']}','{$d['ld']}','{$d['dt']}'
,'{$d[$tble]}')
ELSE IF EXISTS (select id,{$tble} from clockL
WHERE id = '{$d['id']}'
AND dt ='{$d['dt']}'
AND {$tble} = 'NOC'
)
update clockL SET {$tble} ='{$d[$tble]}', ld ='{$d['ld']}' WHERE id = '{$d['id']}'
AND dt ='{$d['dt']}' AND {$tble} ='NOC'
");
//print_r($GLOBALS['mssqldb']);
}
}
謝謝。
這是在循環內部執行的很多條件邏輯。另一種方法是將所有內容放入臨時表中並從臨時表寫入主表。 –
