Get Fields In Table Dynamically

Question

I am trying to create a dynamic query that will allow me to
query a table, pull all of the fields and dump all of the data into
a text file: I have been able to make the dynamic query, but I am
unable to display all of the data on the page when I loop through
my fields... Does anyone know how to do this... Here is my query to
get the fields dynamically... How would I go about actually
querying the datasource and grabbing all of the data from the
fields?
<cfquery name="getfields" datasource="#db#">
select *
from billing
</cfquery>
<cfset thecolumnlist = getfields.columnlist>
<cfloop list="#thecolumnlist#" index="i">
<cfoutput>
#i#
</cfoutput>
</cfloop>
Thanks to anyone who can help me!!!

There are pros/cons to using SELECT *. Its easier typing, but
more db work. Its also easier
to accidentally include columns like "Password" or "Salary".
You can output the query values using array syntax:
#QueryName[ColumnName][rowNumber]# .
<cfoutput query="getFields">
<cfloop list="#getfields.ColumnList#"
index="columnName">
#getFields[columnName][currentRow]#
</cfloop>
<br/>
</cfoutput>
There are a few functions at cflib.org for converting a query
to a CSV file

Or you could do it yourself. Loop through the query and
append the values to a string variable, adding a newline after each
record. Use cffile if you want to save the output to disk. Use
cfcontent/cfheader if you want the output to be downloaded. This is
a popular question so there are many examples. Google for
