如何在使用sql server的子查詢中使用選定的列？

即時通訊使用子查詢返回兩個日期之間的平均金額和總金額，當返回平均金額我必須使用子查詢中選定的列。如何在使用sql server的子查詢中使用選定的列？

以下是我試過的。

tbl_batch_charges 
merchant_id total_transaction_amount settlement_date 
1   33.65      2014-07-01 
1   33.65      2014-07-10 
2   39.36      2014-07-15 


merchant_application_form 
merchant_id active_date 
1    2013-10-20 
2    2014-01-10 

Resulted Table 
merchant_id weekly_transaction total_turnover 
1    xx     67.3 
2    xx     39.36  


select tbl_batch.merchant_id, 
    tbl_merchant.merchant_application_form_active_date, 
    GETDATE() as today_date, 
    (select sum(tbl_batch.total_transactions_amount) from Borgun.dbo.tbl_batch_charges as tbl_batch 
    where tbl_batch.settlement_borgun_date between '2014-07-01' and '2014-10-20' and 
    tbl_batch.merchant_id='9947230') as weekly_total_amount, 
    (select (sum(tbl_batch.total_transactions_amount)/(ceiling(convert(float, abs(datediff(day, active_date, today_date)))/7)))) as total_turn_over 
    from Borgun.dbo.tbl_batch_charges as tbl_batch 
    left join Borgun.dbo.tbl_merchant_application_form as tbl_merchant on tbl_merchant.merchant_application_form_merchant_id=tbl_batch.merchant_id 
    where tbl_batch.merchant_id='9947230' group by tbl_batch.merchant_id;

**我希望商家從他加入當天的日期開始平均每週平均翻倍。 **

你能告訴我我將如何解決在sql服務器。

在此先感謝。

我不明白你的問題是什麼，但重寫你的代碼到下面的語法可能工作

SELECT 
    tbl_batch.merchant_id, 
    tbl_merchant.merchant_application_form_active_date, 
    GETDATE() AS today_date, 
    sum(tbl_batch.total_transactions_amount) as total_amount, 
    avg(tbl_batch.total_transactions_amount) as average_amount 
FROM 
    Borgun.dbo.tbl_batch_charges tbl_batch 
    LEFT JOIN Borgun.dbo.tbl_merchant_application_form tbl_merchant on tbl_batch.merchant_id = tbl_merchant.merchant_application_form_merchant_id 
WHERE 
    Settlement_borgun_date between '2014-07-01' and '2014-10-20' 
    and tbl_batch.merchant_id='9947230' 
GROUP BY 
    tbl_batch.merchant_id, 
    tbl_merchant.merchant_application_form_active_date

請試試這個

SELECT 
    tbl_batch.merchant_id, 
    total_turnover = AVG(tbl_batch.total_transactions_amount), 
    weekly_transaction = SUM(tbl_batch.total_transactions_amount) 
    FROM Borgun.dbo.tbl_batch_charges as tbl_batch 
     LEFT JOIN Borgun.dbo.tbl_merchant_application_form as tbl_merchant 
      ON tbl_merchant.merchant_application_form_merchant_id=tbl_batch.merchant_id 
     WHERE tbl_batch.merchant_id='9947230' 
      AND tbl_batch.settlement_borgun_date between '2014-07-01' and '2014-10-20' 
    GROUP BY tbl_batch.merchant_id, 
       tbl_merchant.merchant_application_form_active_date

不是平均total_transactions_amount – user3668438

所以你想sum_Transaction_Amount的SUM，但AVG的東西或一些不同的值集？ –
