golang gorm 計算字段和 獲取sum()值

計算表lb_ytt_user_money_log 中，字段money的和

代碼如下：

var total_money []int
sqlstr := `select 
					SUM(money) as total_money 
				from 
					lb_ytt_user_money_log 
				where 
					user_id = ? and l_type = 1 and status=1 and (create_time> ? and create_time <= ?)`
Db.Raw(sqlstr, userID, beginTimeNum, endTimeNum).Pluck("SUM(money) as total_money", &total_money)

關鍵在於：Pluck

Db.Raw(sqlstr, userID, beginTimeNum, endTimeNum).Pluck("SUM(money) as total_money", &total_money)

如果把Db.Pluck換成Db.scan得出的就是0
