如何根據條件從重複集中顯示單行？

Question

acquisitionID Logno.    FundName 
1    2     Allocated 
1    2     Potential 
2    34     Allocated 
3    37     Potential 
4    40     Allocated 
4    40     Potential 
5    39     Potential 

我想只顯示那些FundName爲已分配的行，如果有兩個基金給它（即分配/潛在），否則我想顯示它原樣。即

acquisitionID Logno.    FundName 
1    2     Allocated 
2    34     Allocated 
3    37     Potential 
4    40     Allocated 
5    39     Potential 

Answer 1

SELECT AcquisitionID, [LogNo.], min(FundName) 
FROM myTable 
GROUP BY AcquisitionID, [LogNo.]
