All,

I need to query a db table and then write the recordset to an excel spreadsheet.
Can someone provide a query example of what the syntax is for writing to an excel spreadsheet.  I have set an ODBC connection up for the excel already.

Thanks

there is no specific query model to write to an excel file.
in fact, you can't 'write to an excel file' at all - all you can do is save the query output as a comma- or tab-delimited file (.csv), then open in in excel.

there is also a POIUtility, which will allow you to create more complicated xls files (i.e. with proper cell formatting, multiple worksheets, etc etc): http://www.bennadel.com/projects/poi-utility.htm

you could also output your query as plain html table, saving this output in a variable, then serve up this variable using a combination of cfheader and cfcontent tags with proper mime-type to 'pretend' the file is an .xls file - this way users will be prompted to download the file and it will be saved as .xls - but there are various pitfalls with this approach, depending on user's system, browser and which excel version they have installed...

"can't 'write to an excel file' at all"

Azadi... I'm not sure that's entirely true...

can you not use an excel spreadsheet as a datasource for cfgrid and modify the live data ?? Pretty sure I've seen this done (tho not done it myself)

All,

I found this snippet of code on the web.  
It is working for me just fine.

Thanks for your time.

<cfset dsn="mytable">
<cfquery name="daily" datasource="#dsn#" dbtype="ODBC" >
    SELECT *
    FROM mytable
    </cfquery>
    <!--- make some variables to store the dirctory and file name. --->
    <cfset f_dir = "c:\reports\">
    <!--- I like to use the date and time for a file name, but you can name it anything you like by changing the value below. --->
    <cfset f_name = "report.csv">
    <!--- Lets make the file, and put the first row of Column headings in --->
    <cffile action="WRITE" file="#f_dir##f_name#"
    output="myfields" addnewline="Yes">
    <!--- Now lets loop over the RecordSet and fill in the data --->
    <cfloop query="daily">
    <cffile action="APPEND" file="#f_dir##f_name#"
    output="#myfields#"
    addnewline="Yes">
    <!--- End the loop here --->
    </cfloop>
    <br><br><br>
   <cfoutput> <a href="/reports/#f_name#">Here is the excel file</a></cfoutput>
