有个SQL Union 的问题
tblCredit
Credit_desc(varchar 50) Credit_amount(numeric) Credit_date(smalldatetime)
Credit 01 1000.00 13/01/2005
Credit 02 55.69 10/02/2005
Credit 03 50.00 16/12/2004
tblDebit
Debit_desc(varchar 100) Debit_amount(numeric) Debit_date(smalldatetime)
Debit 01 60.00 14/01/2005
Debit 02 55.69 11/02/2005
Debit 03 20.00 31/12/2004
如何用union 把 tblCredit 和 tblDebit 弄成下面的result呢?
tblStatement(sort by date)
All_desc Credit_amount Debit_amount All_date
Credit 03 50.00 null 16/12/2004
Debit 03 null 20.00 31/12/2004
Credit 01 1000.00 null 13/01/2005
Debit 01 null 60.00 14/01/2005
Credit 02 55.69 null 10/02/2005
Debit 02 null 55.69 11/02/2005
请各位大大帮忙, 感激不尽。谢谢。 |

试试看:
select credit_desc as All_desc, credit_amount, 0, credit_date as all_date
union
select debit_desc as All_desc, 0, debit_amount, debit_date as all_date
sort by All_desc |

這裡的人比較不會說謝謝,人家幫了你的忙,說聲謝謝,總是應該的吧!? |
