response.CacheControl="no-cache"
%>

cmd = checkstr(request("cmd"),2)
if cmd="loadteacher" then
response.Charset = "gb2312"
set rs=server.CreateObject("adodb.recordset")
sql="select teacher_id,name from Edu_Person"
rs.open sql,conn,1,3
response.write "{""data"":["
i = 0
do until rs.eof
i = i + 1
response.write "{""Id"":"rs("teacher_id")",""Name"":"""rs("name")"""}"
if irs.recordcount then response.write ","
rs.movenext()
loop
response.write "]}"
response.End()
end if
