在给出的代码中，你想要查询待结算商家的待结算货款和已结算货款，并将结果存储到结构体`BusinessOrderRecharge`中。为了实现这个目标，你需要对代码进行以下修改：

func AppOperateRecharge(a *decorator.ApiBase) error {
	logger.AccessLogger.Info("AppOperateRecharge...")
	resp := adminStruct.BusinessOrderRecharge{}
	err := a.Ts.Table("business_base as a").
		Select("a.bid, a.bname, a.acct_bal, a.buy_Sum_Amt, sum(CASE WHEN b.stmt_status = 1 THEN a.stmt_amt ELSE 0 END) as unpaid_amt, sum(CASE WHEN b.stmt_status = 0 THEN a.stmt_amt ELSE 0 END) as stmt_amt, a.admin_uid, a.user_name, a.status").
		Joins("left join business_bal as s on s.bid=a.bid").
		Joins("left join user_base as u on u.uid=a.admin_uid").
		Joins("left join business_settlement as b on b.uid=a.bid").
		Where("a.bid=?", a.Token.LinkId).
		Group("a.bid").
		Scan(&resp)
	if err != nil {
		return err
	}
	return a.ReturnSuccessCustomResponse(resp)
}

在修改后的代码中，我更正了`Select`函数的参数，将单引号改为双引号，以正确表示字符串。同时，我还在`Scan`函数的参数中添加了取地址符`&`，以便将查询结果存储到结构体`resp`中。

请注意，这只是一个修改的示例，具体根据你的业务逻辑和数据结构来进行调整。
