我想做个户籍表,有成员id1,户口本id2
几个不同的id1有相同的id2,id2是随机固定位数的数字
现在想做个查询,循环输出所有户口信息,不想重复,
sql该怎么写?
举例:
id1  id2   姓名
1    001   a
2    001   b
3    001   c
4    123   d
5    123   e
...
1023 374   x
1024 374   y

结果想输出
001户口信息
a
b
c

123户口信息
d
e
...
374户口信息
x
y


sql语句怎么写?

dim sql,rs,c
c=""
sql="select * from hjb order by id2 asc"
set rs=conn.execute(sql)
do while not rs.eof then
if rs("id2")<>c then
response.write rs("id2")&"户口信息"
end if
response.write rs("姓名")
c=rs("id2")
loop

set rs=conn.execute("select distinct id2 from hjb order by id2 asc")
if not rs.eof then
    do while not rs.eof
        response.write rs(0)&"户口信息:<br>"
        set rs1=conn.execute("select 姓名 from hjb where id2='"&rs(0)&"'")
            do while not rs1.eof
                response.write rs1(0)
                response.write "<br>"
            rs1.movenext
            loop
    rs.movenext
    loop
end if

用group by子句
