我有一个名为ComplimentTransactAssign_tbl
的表。在此表中有许多重复的条目。表结构如下:
TransactID Cmplid
-
32 16
105 17
105 17
290 12
32 16
290 12
我发现我的重复记录如下:
select TransactID from ComplimentTransactAssign_tbl
group by TransactID having count(*) >1 order by TransactID
我想删除重复记录。删除后我想得到这样的输出:
TransactID Cmplid
-
32 16
105 17
290 12
