I need to write some code which will allow a client to query a database and then write the results of the query into a text file (csv) to be placed in the same folder as the database on the server.

The query is easy, but how do I write the text file.

Thanks for the help.

Use CFFILE to write to the text file.

<CFFILE ACTION=WRITE FILE="filename" OUTPUT="output text">

You first need to create the output text, best done in a variable. Let's say you query a database as follows:

<cfquery name="myquery" ...>
SELECT field1, field2
FROM mydbf
</cfquery>

Then create the variable with your CSV text:

<cfoutput query="myquery">
<cfset myoutput=myquery.field1 & "," & myquery.field2>
</cfoutput>

Finally, add the CSV file to your text file:

<cffile action="write" file="c:\myfile.csv" output=#myoutput#>

That should do it! Note that if you want to APPEND to a text file rather than overwriting it, use action="append" in the CFFILE tag.

basically do this:

<cfset filename = "/pathtodb/text.csv">
<cfloop query="queryname">
<cfset Result= "#queryname.field1#" & "," "#queryname.field2#" & "," "#queryname.field3#">
<cffile action="APPEND" file="#filename#" output="#Result#" addnewline="Yes">
</cfloop>

If you don't know the column names or field names then do this:
<cfloop index="i" list="queryname.columnlist" delimiters=",">
<cfset Result = "#Result#" & "#queryname[index]#" & ","
</cfloop>
chop of the last ","

I am not sure if the queryname[index]
is right but I can find out the exact syntax if you need it.
