`````` select a from ((select distinct 第一列 as a, 第一列 as b, 0 as c from table)
union
(select distinct 第二列 as a, 第一列 as b, 1 as c from table))
orderby b
orderby a
orderby c
``````
rocklee00 排序以b，c解决了

rocklee00 排序以b，c解决了

rocklee00 select a from ( (select distinct a1 as a, a1 as b, 0 as c from t ) union (select distinct b1 as a, a1 as b, 1 as c from t) ) as tt order by b,c

rocklee00 table t 字段 a1 ， b2 执行sql select a from ( (select distinct a1 as a, a1 as b, 0 as c from t) union (select distinct b1 as a, a1 as b, 1 as c from t) ) order by b order by a order by c 提示关键字 'order' 附近有语法错误。 怎么改啊，谢谢
