请教group by的语法
"select distinct total,ename,wid,cname from words where cc='"&cc&"' and cname like '%"&ecname&"%' and dclassid in (select dclassid from dclass where dclassid ='"&dclassid&"' or fdclassid = '"&dclassid&"') order by total,cname "
"select distinct total,ename,wid,cname from words where cc='"&cc&"' and cname like '%"&ecname&"%' and dclassid in (select dclassid from dclass where dclassid ='"&dclassid&"' or fdclassid = '"&dclassid&"') order by total,cname "

table
col1,col2,col3
111,111,111
111,111,222
111,222,222
如果你用distinct,是没法取col1的单条记录的
用group by 吧
col1,col2,col3
111,111,111
111,111,222
111,222,222
如果你用distinct,是没法取col1的单条记录的
用group by 吧

是不是空格问题
加distinct ltrim(rtrim(column))
加distinct ltrim(rtrim(column))
