Question

我只是在mysql中创建一些复杂的（是的，在我的pov中作为mysql中的新玩家）查询，包括子选择添加自定义字段。 Okey，我们只需查看查询：

SELECT DISTINCT `cm_reg__`.`TGL`, `cm_reg__`.`JAM`, `cm_reg__`.`ASR`, `cm_reg__`.`CM`, `c_pst`.`NAMA`, `c_pst`.`SEX`, `c_pst`.`AGAMA`, `c_pst`.`EDU`, `c_pst`.`PKJ`, `c_pst`.`ALAMAT`, `c_pst`.`WILAYAH`, `cm_reg__`.`UMUR`, `cm_reg__`.`ASAL`, `cm_reg__`.`NO`, `cm_reg__`.`DR`, `rm_dgs`.`UT`, `cm_reg__`.`DOUT`, `c_pst`.`C_KELUARGA`, `TINDAKAN`, `PENUNJANG`, `IGD`, `TERAPI`, IFNULL(TINDAKAN, `0)` + IFNULL(PENUNJANG, `0)` + IFNULL(IGD, `0)` + IFNULL(TERAPI, `0)` AS TOTAL 
FROM (`cm_reg__`, (SELECT g_sr1301.*, `cm_reg__`.`ASR` AS `ASU`, 
        SUM(CASE WHEN UT LIKE '1%' OR UT LIKE '2%' OR UT LIKE '5%' OR UT LIKE '6%' OR UT LIKE '8%' OR (UT BETWEEN '02' AND '09') OR (UT BETWEEN '36' AND '37') THEN `CHG` END) AS `TINDAKAN`, 
        SUM(CASE WHEN UT BETWEEN 31 AND 34 THEN `CHG` END) AS `PENUNJANG`, 
        SUM(CASE WHEN UT = 01 THEN `CHG` END) AS `IGD`, 
        SUM(CASE WHEN UT = 30 THEN `CHG` END) AS `TERAPI` 
    FROM g_sr1301 
    JOIN cm_reg__ ON g_sr1301.CREG = cm_reg__.`NO` 
    GROUP BY CREG ) AS tabelbiaya) 
JOIN `c_pst` ON `cm_reg__`.`CM` = `c_pst`.`CM` 
JOIN `rm_dgs` ON `cm_reg__`.`NO` = `rm_dgs`.`REGISTER` 
WHERE `cm_reg__`.`TGL` BETWEEN '2013-01-02' AND '2013-01-02' AND `cm_reg__`.`ASR` = 'ak' AND `cm_reg__`.`DOUT` > cm_reg__.TGL 
GROUP BY `NO` ORDER BY `TGL` ASC

我想要的只是一张这样的表：

 ------- --------        --------------- --------------- --------- ------------ -----------
!CREG   !  TGL   ! ...  !CF1 (TINDAKAN) !CF2(PENUNJANG) !CF3(IGD) !CF4(TERAPI) !CF5(TOTAL) !
!-------!--------!      !---------------!---------------!---------!------------!-----------!
! ..    !  ..    ! ...  ! ..            ! ..            !  ..     ! ..         ! ..        !
!-------!--------!      !---------------!---------------!---------!------------!-----------!

请注意，CF是由SUM生成的自定义字段。

不，在我运行查询后会产生一些警告：

Error Code: 1064
You have an error in your SQL syntax; check the manual that corresponds to 
your MySQL server version for the right syntax to use near 
'FROM (`cm_reg__`, (SELECT g_sr1301.*, `cm_reg__`.`ASR` AS `ASU`, 
        SUM(CASE W' at line 2

任何人都可以帮助我吗？因为我是MySQL的新手。谢谢你。：）

更新实际上我使这个查询在Codeigniter模型上工作。我只是意识到问题来自突然出现在IFNULL行中的反引号：

IFNULL(TINDAKAN, `0)` + IFNULL(PENUNJANG, `0)` + IFNULL(IGD, `0)` + IFNULL(TERAPI, `0)`

然后我只是把CI上的活跃记录欺骗到了“甩掉”。那个反叛。当然，来自@ PM77的解决方案可能适用于......

工作查询与@NoDisplayName一样。我试过了，那就好了。但这个过程太长了......也许它来自加入表。

如果没有错，这就是你需要的。

删除

中cm_reg__之前的空心括号

...'FROM (cm_reg__, (SELECT g_sr1301.*, cm_reg__.ASR AS ASU,

并删除tabelbiaya中... AS tabelbiaya)后的近距离括号。将逗号更改为cross join。试试这个

                cm_reg__.JAM,
