我想查找一些數據,有些結果是重複的,但是我想過濾掉重複的數據。Informix防止重複結果
示例數據檢索:
aaa, bbb, ccc, ddd, eee <---Just one copy
aaa, qqq, eee, fff, hhh
bbb, rrr, ggg, lll, mmm
aaa, bbb, ccc, ddd, lll
誰能幫我:我想
aaa, bbb, ccc, ddd, eee <---Duplicate
aaa, qqq, eee, fff, hhh
bbb, rrr, ggg, lll, mmm
aaa, bbb, ccc, ddd, eee <---Duplicate
aaa, bbb, ccc, ddd, eee <---Duplicate
aaa, bbb, ccc, ddd, lll
示例數據!
