Mysql 将命令SQL总和（大小写）数字替换为字母

光晕先生 我有一个这样的程序。 我想用字母替换数字（红色框中）以及程序显示：

问题是：

当我用字母替换数字时，会发生程序错误

当我删除SUM函数时，下一个命令发生的情况将无法识别

我想用字母替换程序输出

下面是我简要介绍的一个程序

$detail = DB::select('select s.nik, s.nama,
    SUM(CASE
    WHEN date_format(b.tanggal, "%d") = "01" and DAYNAME(b.tanggal)="Monday" and j.masuk_senin > b.berangkat and j.keluar_senin < b.pulang and j.wf1 = "WFO" THEN "10"
    WHEN date_format(b.tanggal, "%d") = "01" and DAYNAME(b.tanggal)="Monday" and  j.masuk_senin < b.berangkat and j.keluar_senin < b.pulang and j.wf1 = "WFO" THEN "9"
    WHEN date_format(b.tanggal, "%d") = "01" and DAYNAME(b.tanggal)="Monday" and
    WHEN date_format(b.tanggal, "%d") = "01" and DAYNAME(b.tanggal)="Tuesday" and j.masuk_selasa > b.berangkat and j.keluar_selasa < b.pulang and j.wf2 = "WFO" THEN "10"
    WHEN date_format(b.tanggal, "%d") = "01" and DAYNAME(b.tanggal)="Tuesday" and  j.masuk_selasa < b.berangkat and j.keluar_selasa < b.pulang and j.wf2 = "WFO" THEN "9"
    WHEN date_format(b.tanggal, "%d") = "01" and DAYNAME(b.tanggal)="Tuesday" and 
    ELSE 0 END ) as h1,

    SUM(CASE
    WHEN date_format(b.tanggal, "%d") = "02" and DAYNAME(b.tanggal)="Monday" and j.masuk_senin > b.berangkat and j.keluar_senin < b.pulang and j.wf1 = "WFO" THEN "10"
    WHEN date_format(b.tanggal, "%d") = "02" and DAYNAME(b.tanggal)="Monday" and  j.masuk_senin < b.berangkat and j.keluar_senin < b.pulang and j.wf1 = "WFO" THEN "9"
    WHEN date_format(b.tanggal, "%d") = "02" and DAYNAME(b.tanggal)="Monday" and
    WHEN date_format(b.tanggal, "%d") = "02" and DAYNAME(b.tanggal)="Tuesday" and j.masuk_selasa > b.berangkat and j.keluar_selasa < b.pulang and j.wf2 = "WFO" THEN "10"
    WHEN date_format(b.tanggal, "%d") = "02" and DAYNAME(b.tanggal)="Tuesday" and  j.masuk_selasa < b.berangkat and j.keluar_selasa < b.pulang and j.wf2 = "WFO" THEN "9"
    WHEN date_format(b.tanggal, "%d") = "02" and DAYNAME(b.tanggal)="Tuesday" and 
    ELSE 0 END ) as h2

    from users s
    join tb_presensi b on s.id = b.id_user
    join tb_jammasuk j on s.id = j.id_user
    where b.tanggal between "'.$dari.'" and "'.$sampai.'"
    group by s.id, b.id_user
    order by s.nik ASC');

$detail=DB:：select（'select s.nik，s.nama，
总数（例）
当date_format（b.tanggal，“%d”）=“01”和DAYNAME（b.tanggal）=“星期一”和j.masuk_senin>b.berangkat和j.keluar_seninb.berangkat和j.keluar_selasab.berangkat和j.keluar_seninb.berangkat和j.keluar_selasa

我相信您遇到了一个程序错误，因为您案例的结果被插入到求和函数中。如果我错了，请有人纠正我，但我认为您不能在字符串上使用SUM。

什么是“程序错误”消息？当date_format（b.tanggal，“%d”）=“01”和DAYNAME（b.tanggal）=“星期一”和j.masuk_senin>b.berangkat和j.keluar_senin，然后“这是10”我想用字母显示每个数字。但是当我删除SUM命令时，下一个“as”是不可读的。但是我如何在不使用SUM的情况下显示字符串呢？因为当我不使用SUM时，我识别的命令只是首字母“as”
