好难的问题呀~~高手们看看呀(0分)

q_sql:='select a.ip ,b.intime from b,a where a.ip=sb and b.intime>=:xd and b.intime<=:yd group by b.intime';

query2.parambyname('xd').asdatetime:= datetime1;
query2.parambyname('yd').asdatetime:=datetime2;

这样谢老是说我的group 有错误~~

general sql error
ora-00979:不是group by 表达式

select a.ip ip,b.intime intime from b,a where a.ip=sb and b.intime>=:xd and b.intime<=:yd group by ip,intime;
你这家伙太小气了

我不是已经在另外一贴中回答了你的问题了
另： 你这家伙太小气了

用group by 后select 的字段必须是聚合函数,或group by 字段.
