How do I send a database query to a text file?

SQL Server 
You can use bcp and xp_cmdshell, assuming the user who needs to run this query has sufficient privileges. Here is a way to send the results of a stored procedure to a file: 
SET @cmd = 'bcp "EXEC pubs..reptq1" queryout' 
    +' "c:\query.txt" -c -Usa -Ppassword' 
    +' -SLOCALHOST"' 
EXEC master..xp_cmdshell @cmd, NO_OUTPUT
Another option is to send the contents of a table to a file, e.g. 
SET @cmd = 'bcp pubs.dbo.authors out' 
    + ' c:\authors.txt -c -t' 
    + ' -SLOCALHOST -Usa -Ppassword' 
EXEC master..xp_cmdshell @cmd, NO_OUTPUT
If you are using Windows Authentication, and not SQL Server Authentication, there would be one minor change: 
SET @cmd = 'bcp pubs.dbo.authors out' 
    + ' c:\authors.txt -c -t ' 
    + ' -SLOCALHOST -E
EXEC master..xp_cmdshell @cmd, NO_OUTPUT
Alternatively, you can use OSQL to achieve the same kind of things, though the syntax is slightly different: 
SET @cmd = 'OSQL -SLOCALHOST -dPubs ' 
    + ' -Usa -Ppassword' 
    + ' -Q"SELECT * FROM Authors"' 
    + ' -oc:\authors.txt' 
EXEC master..xp_cmdshell @cmd, NO_OUTPUT
And again, if you are using Windows Authentication, there is a slight change: 
SET @cmd = 'OSQL -SLOCALHOST -dPubs -E
    + ' -Q"SELECT * FROM Authors"' 
    + ' -oc:\authors.txt' 
EXEC master..xp_cmdshell @cmd, NO_OUTPUT
If this is something I need automated, I usually create the stored procedure in master, and create a job (owned by SA) — and either schedule it using SQL Server Agent, or start the job manually. This eliminates the need to worry about who is calling it manually and to make sure to set up permissions correctly for everyone who might ever want to call it... 
See Books Online for more information and command line switches for the bcp and osql utilities. 
SQL Server or Microsoft Access 
You can also handle saving a query to a file using ASP and FileSystemObject, though I strongly recommend avoiding this approach if possible. If your result set is going to be more than a few thousand lines, this will cause serious memory issues on the server running the ASP page. (You could experiment with looping through the resultset and calling writeline() for every iteration of the loop, as it may represent less of a burden than drawing the entire set into GetString() — string concatenation is not a strength of VBScript, and GetString() is just a fancy way of saying, "loop through all the rows, and concatenate them as you go." It's more efficient than that, but you get the gist.) 
This example creates a CSV file and links to it. So, we start with this table: 
CREATE TABLE blat(foo INT, bar VARCHAR(32)) 
INSERT blat(foo, bar) VALUES(1, 'foo') 
INSERT blat(foo, bar) VALUES(2, 'bar') 
INSERT blat(foo, bar) VALUES(3, 'foobar') 
Now, ignoring the other enhancements we would make to this script (e.g. creating a stored procedure in SQL Server), we can see that the following will generate a CSV string and place it in a file. 
    set conn = CreateObject("ADODB.Connection") 
    conn.open "<connection string>" 
    set rs = conn.execute("SELECT foo, bar FROM blat") 
    csvText = rs.getString(2,,",",VBCrLf) 
    rs.close: set rs = nothing 
    conn.close: set conn = nothing 
    set fso = CreateObject("Scripting.FileSystemObject") 
    set fs = fso.CreateTextFile(Server.MapPath("csv.csv"), true) 
    fs.close: set fs = nothing 
    set fso = nothing 
    response.write "Right-click to download: " & _ 
        "<a href=csv.csv>csv.csv</a>" 
You would probably want to use timestamp, random numbers, GUIDs, etc. to name new files as they are created, if you need to avoid overwriting previous versions.
