golang gorm 怎么得到sum()值？

我感觉是你没有对应好值，SUM(a.fraction) as totalScore,

var totalScore []int db.Table("xy_subject_answer a"). /* Select("SUM(a.fraction) as totalScore"). */ Joins("left join xy_staff_auswer_option b on (a.id = b.subject_answer_id)"). Where("b.staff_answer_id = ?", 282).Pluck("SUM(a.fraction)", &totalScore) 我按你的这么写了，还是不行，最终用的上面的这段，得到了正确的结果

var totalScore []int db.Table("xy_subject_answer a"). / Select("SUM(a.fraction) as totalScore"). / Joins("left join xy_staff_auswer_option b on (a.id = b.subject_answer_id)"). Where("b.staff_answer_id = ?", 282).Pluck("SUM(a.fraction)", &totalScore) 我按你的这么写了，还是不行，最终用的上面的这段，得到了正确的结果
