Question

我有一些代码：

        $done_tasks = R::getCol('SELECT count(*) FROM tasks WHERE `status` = "done" AND id IN
        (SELECT task_id FROM tasksemployess WHERE employee_id = ?)', array($_SESSION['employee']['id']));

        $failed_tasks = R::getCol('SELECT count(*) FROM tasks WHERE `status` = "failed" AND id IN
        (SELECT task_id FROM tasksemployess WHERE employee_id = ?)', array($_SESSION['employee']['id']));

        $process_tasks = R::getCol('SELECT count(*) FROM tasks WHERE `status` = "in_process" 
        OR `status` = "cheking" OR `status` = "remaking" AND id IN
        (SELECT task_id FROM tasksemployess WHERE employee_id = ?)', array($_SESSION['employee']['id']));

        $avg_mark = R::getCol('SELECT avg(mark) FROM tasks WHERE id IN
        (SELECT task_id FROM tasksemployess WHERE employee_id = ?)', array($_SESSION['employee']['id']));

        R::exec('UPDATE FROM persresults SET done_tasks = ?, failed_tasks = ?, process_tasks = ?, avarage_mark = ?,
        WHERE employee_id = ?',array($done_tasks[0], $failed_tasks[0], $process_tasks[0], $avg_mark[0], $_SESSION['employee']['id']));

除最后一个请求外的所有请求都返回一个数组，因此在上一个请求中，我将它们称为数组，似乎一切正确，但是：

根据结果更新SET done_tasks = 3，failed_tasks = 0， process_tasks = 0，avarage_mark = '67 .0000'，WHERE employee_id = 19 An 发生错误：SQLSTATE [42000]：语法错误或访问冲突： 1064您的SQL语法错误；检查手册对应于您的MySQL服务器版本以使用正确的语法接近'FROM persresults SET done_tasks = 3，failed_tasks = 0， process_tasks = 0，在第1行上显示为“

如您所见，插入的值会根据需要传递，但是由于某种原因会发生此错误。

您不应该使用UPDATE FROM（只是UPDATE table_name），并且在更新之前WHERE之前有一个逗号错误

 R::exec('UPDATE persresults 
    SET done_tasks = ?
    , failed_tasks = ?
    , process_tasks = ?
    , avarage_mark = ?
   WHERE employee_id = ?',array($done_tasks[0], 
         $failed_tasks[0],
         $process_tasks[0],
         $avg_mark[0], $_SESSION['employee']['id']));

当我尝试从RedBeanPHP通过R :: exec执行查询时，为什么会发生错误？
