Question

我有一些这样的代码：

REPLACE INTO digisob_rekap_peruser(
    user_rk,
    lokasi_lk,
    target_lk,
    pertarget //2. data does not enter this column ,
    vis_lk,
    nsb_lk)
SELECT
    jadwal_userid,
    lokasi_lk,
    target_kunjungan*$x,
    vis_lk/target_lk*100 AS pertarge //1. this line,
    COUNT(jadwal_userid) AS total,
    SUM(SJ_Tsel_3_2) AS jualan
FROM
    jadwal,
    data_kunjungan,
    user,
    digisob_rekap_peruser
WHERE

数字1有结果，但该结果未进入数字2的列。

用于百分比计算的默认数据类型为likley，导致数据丢失。

您需要将值强制转换为小数/浮点数/双精度数等。

select 1/10
-- 0
select 1/10 * 100
-- 0
select cast(1 as decimal)/cast(10 as decimal)
-- 0.1000000000000000000
select cast(1 as decimal)/cast(10 as decimal) * 100
-- 10.0000000000000000
select cast(cast(1 as decimal)/cast(10 as decimal) * 100 as int)
-- 10
select cast(cast(cast(1 as decimal)/cast(10 as decimal) * 100 as int) as varchar(4)) + '%'
-- 10%

选择MySQL查询中的div列不适用于replace into
