摘要:asp实现读取数据库输出json代码
[u]复制代码[/u] 代码如下:
Function GetTable(Table,Where,Order,OrderSort,curpage, pagesize,MiniJson) 'Author : nigou '使用方法 : Response.Write GetTable(Table表名,Where条件,Order主键(必须),OrderSort(asc,desc),curpage当前页, pagesize每页条数,MiniJson是否输出为miniUI格式) '     dim i, j ,rs     if OrderSort="" Then OrderSort="asc"     if Where="" Then Where="asc"     Set Rs=Server.CreateObject("adodb.recordset")     if curpage>1 then         TmpSql="select a.* from ( select top  " & (curpage) * pagesize & " * from " & Table & " where " & where  & " order by " & Order & " " & OrderSort & ") a left join ( select top " & (curpage-1) * pagesize  & " * from " & Table & "  where " & where  & " order by " & Order & " " & OrderSort & ") b on a." & Order & "=b." & Order & " where iif(b." & Order & ",'0','1')='1'"     else         TmpSql="select a.* from ( select top  " & (curpage) * pagesize & " * from " & Table & " where " & where  & " order by " & Order & " " & OrderSort & ") a "     end if     if pagesize=0 Then TmpSql = "select * from " & Table         Rs.open TmpSql,conn,1,1         RealSize=Rs.recordcount         for i=0 to Rs.recordcount-1             TmpJson= TmpJson & "{"             for j=0 to Rs.fields.count-1                 TmpJson= TmpJson & """" &(Rs.fields(j).name) & """ : "                             TmpJson= TmpJson & """" & Rs(j) & """"                 if j<Rs.fields.count-1 then TmpJson= TmpJson & " , "             next             TmpJson= TmpJson & " }"             if i<Rs.recordcount-1 then TmpJson= TmpJson & ","             TmpJson= TmpJson & vbcrlf             rs.movenext         next         Rs.close     if MiniJson=1 Then         CountSql="select count("& order &") from " & Table & " where " & where         Rs.open CountSql,Conn,1,1         Counts=Rs(0)         Rs.Close         GetTable=ToMiniUi(TmpJson,Counts)     Else         GetTable=toJson(TmpJson)     end if     Set Rs=nothing End Function function toJson(JsonStr)     toJson="[" & vbcrlf & JsonStr & vbcrlf & "]" end function Function ToMiniUi(JsonStr,total)     ToMiniUI="{"     ToMiniUI=ToMiniUI & """total"":"" " & total & """," & vbcrlf     ToMiniUI=ToMiniUI & """data"": [" & JsonStr     ToMiniUI=ToMiniUI & "]}" End Function
PS:最后的参数是针对miniUI开发的,可以无视 以上就是本文的全部内容了,希望大家能够喜欢。
