说清楚你的问题。

如果你不知道怎么问,先看看软件的帮助文档。

if alltime = "" then
    st = rf("st")
    et = rf("et")

    y1 = rf("y1")
    m1 = rf("m1")
    d1 = rf("d1")
    h1 = rf("h1")
    mm1 = rf("mm1")

    y2 = rf("y2")
    m2 = rf("m2")
    d2 = rf("d2")
    h2 = rf("h2")
    mm2 = rf("mm2")
    if st="1" then
        ifs = " (datediff(n,'" & dtm1 & "',createtime)>=0 "
    else
        ifs = " (datediff(n,'" & dtm1 & "',createtime)>0 "
    end if
    if et="1" then
        ifs = ifs & " and datediff(n,'" & dtm2 & "',createtime)<=0) "
    else
        ifs = ifs & " and datediff(n,'" & dtm2 & "',createtime)<0) "
    end if
    ifs=" (createtime between '"& dtm1 &"' and '"& dtm2 &"') "
else
    ifs = ""
end if
if ifs<> "" then ifs = " and " & ifs

sql="SELECT mobile FROM paper_chance "&_
"WHERE (mobile IN (SELECT mobile FROM paper_chance "&_
" WHERE (ischance = 1 "&ifs&") "&_
" GROUP BY mobile HAVING (COUNT(*) >= 5))) "&_
" AND (content like '"&key&"%') "&ifs&" order by mobile "

sql="SELECT mobile FROM paper_chance "&_
"WHERE (mobile IN (SELECT mobile FROM paper_chance "&_
" WHERE (ischance = 1 "&ifs&") "&_
" GROUP BY mobile HAVING (COUNT(*) >= 5))) "&_
" AND (content like '"&key&"%') "&ifs&" order by mobile "

这语句的条件就是:
  在PAPER_CHANCE表中,把标识为真,在某一时间范围内且MOBILE值相同的数据出现5次以上而且有一次内容是KEY相关的内容的手机号取出来

sql="select * from "&tb&" where id>0"
if msg<>"" then
sql=sql& " and message='"& msg &"'
end if

if mobile<>"" then
sql=sql& " and mobile='"& mobile &"'"
end if
...

我想你要的是这种吧
