--不甚清楚楼主想怎么查,BETWEEN 不可以吗? SELECT * FROM TABLE WHERE MONEY BETWEEN 100 AND 200;
其实不是很清楚你要什么样的结果,按照自己的想法写了一下: TEST DATA:如果你的数据库支持wm_concat函数的话就好做很多: select t1.data_rank, wm_concat(t1.id) id from (select id, t.money, case when t.money >= 100 and t.money < 200 then '100—200的数据' when t.money >= 200 and t.money < 400 then '200—400的数据' when t.money >= 400 and t.money < 1000 then '400—1000的数据' else '其他数据' end data_rank from test t) t1 group by t1.data_rank; 如果数据库版本较低不支持: select t2.data_rank, LTRIM(MAX(SYS_CONNECT_BY_PATH(T2.id, ',')), ',') from (select t1.id, t1.data_rank, row_number() over(partition by t1.data_rank order by t1.id) rn from (select id, t.money, case when t.money >= 100 and t.money < 200 then '100—200的数据' when t.money >= 200 and t.money < 400 then '200—400的数据' when t.money >= 400 and t.money < 1000 then '400—1000的数据' else '其他数据' end data_rank from test t) t1) t2 START WITH T2.RN = 1 CONNECT BY PRIOR RN = RN - 1 AND PRIOR T2.data_rank = t2.data_rank GROUP BY T2.data_rank order by data_rank result as below:
Sorry,#3的TEST DATA 和RESULT的图弄反了

中文字符乱码,你数据库字符集有问题,网上找到的答案是: alter database character set internal_use ZHS16GBK; 不过好像有限制,你可以试试,实在不行就显示英文吧
