每运行5,10,60,3600分钟的crons， 当我检查errorlog时，我看到非常多的死锁异常，几乎每5分钟cron就会发送死锁，超时和序列化错误来记录。
如果我理解使用同一个表的两个或多个查询时发生了很好的死锁，那么我的代码中很有可能。
我在每个cron中使用表MAP 2次，因为我需要映射每个团队，
例如：
切尔西在映射后回归切尔西足球俱乐部 映射后的埃弗顿回归埃弗顿足球俱乐部
我从大型xml文件中获取团队，当我杀死所有进程时cron5在2分钟内运行即可，但是当其他进程启动时，它需要这样的时间......
当我通过SHOW OPEN TABLES WHERE in_use>0查看时，我明白了
map表in_use主要是2，有时是1。
function getMap($country,$data){
//echo $data . '<br>';
$fdata = $data;
$query = $this->PDO->prepare("CALL GetMap(:data)");
$query->bindParam(':data', $fdata);
$query->execute();
//echo 'DATA: ' . $data. ' RES: '.$res . '<br>';
$res = $query->fetchColumn();
if($res!=''){
$query->closeCursor();
$sql = "UPDATE map SET Country = :country WHERE Base = :base";
$q2 = $this->PDO->prepare($sql);
$q2->bindParam(':country', $country);
$q2->bindParam(':base', $res);
$q2->execute();
//echo $res;
return $res;
}
else
{
$query->closeCursor();
$this->fillMap($country,$fdata);
return $fdata;
}
}
这是GetMap的程序
DELIMITER //
CREATE PROCEDURE GetMap(p_team VARCHAR(100))
BEGIN
SELECT Base FROM map WHERE
map.Base = p_team OR
Ver1 = p_team OR
Ver2 = p_team OR
Ver3 = p_team OR
Ver4 = p_team OR
Ver5 = p_team OR
Ver6 = p_team OR
Ver7 = p_team OR
Ver8 = p_team OR
Ver9 = p_team OR
Ver10 = p_team OR
Ver11 = p_team OR
Ver12 = p_team;
end //
DELIMITER ;
现在我的问题是当使用php锁定该表时如何解锁表映射？ 另外我需要说的是我在xml读取之前启动事务，并在一切都完成时提交，因此事务等待大约2分钟时可能没有锁定映射。这可能是我得到超时错误的原因，我可以将其移动到循环内或更改mysql超时。
编辑详细代码： 检查$ this-＆gt; getMap（）;什么是最常用的表。
