1.找出重复数据
select count(1),uuid from ts.test group by uuid having count(1)>1 order by 1 desc ;---找出重复数据
select * from ts.test E WHERE E.ROWID > (SELECT MIN(X.ROWID)
FROM ts.test x WHERE X.UUID=E.UUID AND E.TRAN_DT=X.TRAN_DT);---找出重复数据
2.删除重复数据
delete from ts.test E WHERE E.ROWID > (SELECT MIN(X.ROWID) FROM ts.test x WHERE X.UUID=E.UUID AND E.TRAN_DT=X.TRAN_DT);----删除一条
--delete from ts.test where uuid='2f1cfa5b492d45a18c036400e4176e06';----删除2条!!!不建议使用
