Question

我知道这个问题出现在很多网站上，但仍然存在。

这是在Code中调用的Query：

$exec = $dbh->prepare($query); //query as shown below
                pr($exec); // output for me
                $exec->execute();

我从pdo或任何事情中都没有错误。如果我以1：1复制查询，我会得到正确的值。

错误的价值是＆＃39;总和＆＃39;和＆＃39; sum_bank＆＃39;，所以计算也是错误的。

INSERT INTO `db`.`inserttable` 

                    SELECT null as `id`, `state`,`company`.`rid`,
                    8 as `month`,
                    19 as `day`,
                    (
                    SELECT count(company2.cid)
                        FROM `company` as `company2`
                        LEFT JOIN `db`.`gid` ON `company2`.`cid` = `db`.`gid`.`cid`
                        WHERE `company2`.`state` = `company`.`state` AND gid.`gid` = `company`.`rid`
                    ) as `sum`,
                    SUM(IF(`ctype` = 'company', 1, 0)) as `sum_company`,
                    (
                    SELECT count(company2.cid)
                        FROM `company` as `company2`
                        LEFT JOIN `db`.`gid` ON `company2`.`cid` = `db`.`gid`.`cid`
                        WHERE `company2`.`state` = `company`.`state` AND `gid`.`gid` = `company`.`rid` AND `ctype` = 'bank'
                    ) as `sum_bank`,
                    (SUM(IF(`ctype` = 'company', 1, 0)) / (SELECT `sum`)) * 100 as `prc_company`,
                    (SUM(IF(`ctype` = 'bank', 1, 0)) / (SELECT `sum`)) * 100 as `prc_bank`,
                    SUM(`isBir`) as `sum_isBir`,
                    SUM(`isCgr`) as `sum_isCgr`,
                    SUM(`isBar`) as `sum_isBar`,
                    (SUM(`isBir`) / (SELECT `sum`)) * 100 as `prc_isBir`,
                    (SUM(`isCgr`) / (SELECT `sum`)) * 100 as `prc_isCgr`,
                    (SUM(`isBar`) / (SELECT `sum`)) * 100 as `prc_isBar`
                    FROM `db`.`company`
                    GROUP BY `db`.`company`.`state`, `db`.`company`.`rid`

用于错误检查：

$dbh  = Database::getInstance();

            try {
                $dbh->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
                $dbh->setAttribute( PDO::ATTR_EMULATE_PREPARES, false );
                $exec = $dbh->prepare($query);
                pr($exec);
                $exec->execute();
                pr($dbh->errorInfo());

            } catch(PDOException $e) {
                return array('Exception' => array('code' => $e->getCode(), 'message' => $e->getMessage()));
            }

答案是：

 array(1) {
 [0]=>
  string(5) "00000"
}

如此认真......我没有错误

我可以自己解决：

错误是：来自company company2 转为：FROM db。company为company2

在php我的管理员中我选择了正确的数据库，因为它在那里工作。

遗憾的是，它没有以任何形式犯错误，这会让我节省很多时间

SQL语句适用于PhpMyAdmin，但不适用于Php脚本
