当前表格如下：
Acct|Date|Rate Center_01|Charge_01|UOS_01|Rate Center_02|Charge 02|UOS_02|..out to set10
a |1/1/1|01 |100 | 3 | 15 | 75 |6 |........
a |1/2/1|04 |70 | 6 | 12 | 35 |12
b |2/2/2|03 |50 | 8 | 07 | 30 |15 |.........
我希望它看起来像：
Acct|Date|Rate Center|Charge|Units|
a |1/1/1|01 |100 |3
a |1/1/1|15 |75 |6
a |1/2/1|04 |70 |6
a |1/2/1|12 |35 |12
b |2/2/2|03 |50 |8
b |2/2/2|07 |30 |15
我想确保帐户和日期仅显示当天分配的费率中心和单位。目前，我的查询是将同一帐户中不同日期发生的费率重复。有没有办法限制重复的东西？
