Sending e-mails in Oracle 10g

Question

Hello, all
I have a query that returns on average ~150 rows. I want to set up a job to spool the query's results to a .txt or .csv file and then e-mail it as an attachment.
I am using the sys.utl_mail package to send other query results, however when attempting to use it for this particular query it is failing - presumably due to the 32k size restriction.
Has anyone ran a query returning a number of rows then distributed it via an e-mail attachment? What's the best way to go?

Answer 1

I perhaps should have clarified: I am looking for a way to put query results in an attachment and send them via e-mail. Given certain solutions' limitations I was seeking best practices for doing this. My attachments will certainly exceed the 32k limit of some options.
I decided on the mail_demo package available here: http://www.oracle.com/technology/sample_code/tech/pl_sql/htdocs/maildemo_sql.txt.
There was a terrific post regarding its use here: Re: Send Email with Attachement more than 32K I took the code sample from hoek and plugged my own values in where appropriate.
I am able to populate a .csv with my query results and have it e-mailed it successfully in a .csv (Yay!), however there are two problems:
1. whereas the query returns 150 rows on its own the .csv in my Inbox has 11,325 rows.
2. I would like to put a delimiter between the columns, so the output is more legible
If something jumps out at anyone please advise. Thanks in advance for any assistance.
