Bill_date Total 
28/10/13 10000 
27/10/13 5000 

付款表

Answer 1

SELECT t1.bill_date as `date`, t1.Total as Credit, t2.amount as debit FROM Bills t1 
LEFT JOIN Payments t2 ON t1.bill_date= t2.Paid_on 
UNION 
SELECT t2.Paid_on as `date`, t1.Total as Credit, t2.amount as debit FROM Bills t1 
Right JOIN Payments t2 ON t1.bill_date <> t2.Paid_on 
UNION 
SELECT t1.bill_date as `date`, t1.Total as Credit, t2.amount as debit FROM Bills t1 
LEFT JOIN Payments t2 ON t1.bill_date <> t2.Paid_on 

Answer 2

你可以試試這個代碼。

SELECT concat(`Bill_date`,' ',`Total`) FROM `tblname` 

Answer 3

select b.bill_date, sum(b.total), sum(p.amount) 
from bills b full outer join payments p on b.bill_date=p.paid_on 
group by b.bill_date 
order by b.bill_date 

您需要完整的外部聯接來獲得行具有票據天，但沒有支付和天有付款，但沒有票據。

Answer 4

試試這個

SELECT t1.bill_date, t1.total as Credit, t2.total as debit FROM Bills t1 
LEFT JOIN Payments t2 ON t1.bill_date= t2.bill_date 
UNION 
SELECT t2.bill_date, t1.total as Credit, t2.total as debit FROM Bills t1 
RIGHT JOIN Payments t2 ON t1.bill_date= t2.bill_date 

Answer 5

查詢應該是這樣的，

SELECT t1.bill_date, t1.total AS Credit, t2.amount AS debit 
FROM Bills t1 
LEFT JOIN Payments t2 ON t1.bill_date = t2.paid_on 
UNION 
SELECT t2.paid_on, t1.total AS Credit, t2.amount AS debit 
FROM Bills t1 
RIGHT JOIN Payments t2 ON t1.bill_date = t2.paid_on
