I have a ASP file, select data from SQL Server and display it in excel. But it has two problems.

1. Some data is missing (I want to display a table in the following:)

Group    Subtotal
Textbook  1
book      1
Total:    2

2. Chinese data can't display

1st, I wrote this in Notepad since i am witout my usual developement PC - so this might have some bugs (hell it might not even work!)
2nd, there is minimal error checking - but if it works,  you can add that!

Since not a lot of detail was supplied, i assumed a few things to give you an example.

Assumptions
> DB is set up with a DSN called My_DSN
> Table that holds data is called Table1
> the Group field in Table1 is called 'Group'
> the SubTotal field in Table1 is called 'SubTotal'


Look out for items marked *** - these should be edited to suit

Here goes...

<%
''Consts
Const sDSN="My_DSN" '***Set this to required DSN***

''Dim variables
Dim objCn
Dim objRst
Dim sSql
Dim sErr

'Set up SQL to retrieve records *** Set this as required ***
sSql = "SELECT Group, Subtotal FROM Table1"

'Create connection
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.Open "DSN" & sDSN & ";"

GetRS objCon, objRst, sErr

'******************* Functions **********************
Function GetRS(byref objCon, byref rs, Byval sQuery, ByRef ErrString, Byval iItemsPerPage)
on error resume next
'Create RS and Get the data Values***************************************
     'Create recordset object
Set rs = Server.CreateObject("ADODB.Recordset")
With rs
     .ActiveConnection = objCon
     .CursorLocation = adUseClient
     .CursorType = adOpenForwardOnly
     .LockType = adLockReadOnly
     .Source = sQuery
     .PageSize = iItemsPerPage
     .Open
     Set .ActiveConnection = Nothing     'Disconnect the recordset
End With
if Err <> 0 then ErrString = "Error retrieving data for: " & sQuery & "<BR>" & Err.Description & " (" & Err.Number & ")"
     
End Function


Function CleanUp
If IsObject(objRst) Then
    If Not objRst Is Nothing Then
         If objRst.State = 1 Then objRst.Close
         Set objRst = Nothing
    End If
End If

If IsObject(objConn) Then
    If Not objConn Is Nothing Then
         If objConn.State = 1 Then objConn.Close
         Set objConn = Nothing
    End If
End If
End Function

theres the 1st bug, spotted it when i read it back!!!

... i called the connection objCn then i try to use objCon then i attempt to clean up objConn - whats going on!

These will need to be made all the same name!

A good argument for option explicit!!!

ivychan, add this at the very top of the asp file

<%@ LANGUAGE="VBSCRIPT" %>
<% Option Explicit %>

to catch those inevitable bugs!  (well i did do it in note pad (not realy an excuse i suppose!))

I'll keep taking the happy pils ;)

let me talk about the chinese data not displaying...
first, are you data in unicode format? if they are then u should use the charset "utf-8".
if youre not using unicode format then you should find the appopriate charset for the language you are using...
as i understand there are few types of chinese language...
tradtional and simplified...

heres an example of setting a charset...

=simplified chinese=
<META HTTP-EQUIV="Content-type" CONTENT="text/html; charset=gb2312">

use "big5" for traditional
use "utf-8" for unicode encoding...

cheers...

Commented:
can u check the table in ur db where your data is coming from is its storing the unicode format data properly...
it should look like "&#3649;&#3621;&#3604;&#3610;&#3619;&#3641;&#3658;&#3588;"

if they are "????" then ur data is not stored correctly...

are your fields in nvarchar data type?

check out in your code if ur setting the codepage property... that overwrites the charset when it is set.

or better yet post a sample of ur code...
cheers

1. The field Type is nvarchar
2. It can store chinese e.g.&#35430;&#39511;
3. my program set code page and charset

<%@codepage 950 %>
<META HTTP-EQUIV="Content-type" CONTENT="text/html; charset=big-5">

But export to excel that display " Ç¼½»PªÀ·|µo®i¡v¾Ç³N¬ã°Q·|½×¤ "

Please help!

Commented:
if u display it in a web page... are the chinese character correctly displayed?

Author

Commented:
Yes.
In Office 97, you need to run the following first...
Traditional Chinese       Chtsupp.exe
Simplified Chinese       Chssupp.exe

These are on the CD (see the ValuPack)

Commented:
ive tried exporting my chinese unicode data to excel using ASP and the characters are displayed properly...
im not sure whats wrong with your situation...
im using windows 2000 prof, and office 2000 prof ed. if that helps...
jerome

 
ivychan, did you get this sorted?
Did the Chtsupp.exe/Chssupp.exe off the CD do the job?
