Excel Sheetname

Hi,

I'm uploading files to the server to then put the content into access... but to do so, I need to know the name of the excel sheet for the sql query...

rstExcel.Open "SELECT * FROM [Sheet1$];", cnnExcel, adOpenStatic, adLockPessimistic

THis works, but the data has to be in a sheet called 'Sheet1'... if it has another name, it doesn't work...

How can I get the sheet name?

The trick is the sheet name at the bottom of the Excel file. Excel by default has three sheets (tabs) at the bottom of the .xls document. To find the sheet name, just click on the bottom of it. Whenever I used to upload excel files, I always renamed them something unique and 1 word.

The other thing you can do is use the Access link utility to import the Excel sheet. That will actually allow you to select the individual Excel sheet from the Excel file.

Hopefully this helps, if not, contact me.

I think what DarkHalf was asking was "How do I *FIND* the name of the sheets in a given 'xls' file?"

In some databases, you can ask the DB what tables it contains. If we consider a ".xls" file to be the moral equivalent of a database, when accessed via the JET OLEDB driver, you'd like to be able to find all the names and schemas of all the "tables" (the sheets).

I was hoping somebody else would answer this, but I am *GUESSING* (purely a guess!!) that if it is possible without actually scripting the Excel object (which is a messy-as-all-get-out task!) then the likely answer will lie in ADOX.

Oh, heck...it's actually a piece of cake.

Here's a demo ASP page:

Code:

<%
connstr = "Provider=Microsoft.Jet.OLEDB.4.0;" _
     & "Data Source=" & Server.MapPath ("junk.xls") & ";" _
     & "Extended Properties=""Excel 8.0;HDR=Yes""" 

Set cat = Server.CreateObject("ADOX.Catalog")
cat.ActiveConnection = connstr

Response.Write "Found " & cat.Tables.count & " tables in that XLS file.<p>"
For tnum = 0 To cat.Tables.count - 1
    Set tbl = cat.Tables(tnum)
    Response.Write "Table " & tnum & " is named " & tbl.Name & "<br/>" & vbNewLine
Next
%>

Worked like a charm first time. You could even get the column names of all the columns in each table using ADOX. And more.

Since DarkHalf already *HAS* a connection to the spreadsheet, as demoed by the
rstExcel.Open "SELECT * FROM [Sheet1$];", cnnExcel, adOpenStatic, adLockPessimistic
code line, he/she could just do
<%
Set cat = Server.CreateObject("ADOX.Catalog")
Set cat.ActiveConnection cnnExecl
%>
and be ready to go.

*******************

DarkHalf: How come you open that spreadsheet with adOpenStatic and adLockPessimistic??? Your comments said you were *READING* from that spreadsheet, so why are you locking it for *WRITE*???

And adOpenStatic would only be needed if you were going to do random record positioning within the rows of the sheet. And even then, the Excel driver won't support that, so you'd need to also specify a client-side cursor.

Thank you very much Old Pedant, that's exactly what I was looking for to do... Also, thank you for correcting my syntax for my connection string...
