Sending e-mail attachments with utl_mail.

Question

Hello guys i would like to add an attachment to an e-mail using utl_mail
I have gotten this part done without a problem.
My problem now is that i have to loop a table and make the contents of the table an attachment to the e-mail.
So here is what i have so far.
DECLARE
   b64   VARCHAR2 (512) := 'WELL THIS IS A WHOLE LOT OF DATA!';         -- etc., as above
   txt   VARCHAR2 (512) := 'Dear Scott: ...';                -- etc., as above
BEGIN
   UTL_MAIL.send_attach_varchar2 (sender => 'xxxx'
                                , recipients => [email protected].'
                                , MESSAGE => txt
                                , subject => 'Attachment demo'
                                , att_mime_type => 'application/x-gzip'
                                , attachment => b64
                                , att_inline => TRUE
                                , att_filename => 'hugo.txt'
END;
/and i have a loop like this.
for rec in
   (SELECT
    FWTMP_REGPO_INV_NUM,
    FWTMP_REGPO_ERR_BAD_FUND,
    FWTMP_REGPO_ERR_BAD_ORGN,
    FWTMP_REGPO_ERR_BAD_PROG,
    FWTMP_REGPO_ERR_BAD_ACCT,
    FWTMP_REGPO_ERR_AMT_MORE,
    FWTMP_REGPO_ERR_NOPIDM_MATCH,
    FWTMP_REGPO_ERR_QTY_MORE,
    FWTMP_REGPO_ERR_ENC_LESS,
    FWTMP_REGPO_ERR_NOFP_MATCH,
    FWTMP_REGPO_ERR_NOFY_MATCH,
    FWTMP_REGPO_FTVFSYR_FSYR,
    FWTMP_REGPO_VEND_NUM,
    FWTMP_REGPO_ERR_INV_FOUND,
    FWTMP_REGPO_INV_AMT,
    FWTMP_REGPO_PO,
    fwtmp_regpo_credit_memo
FROM FWTMP_REGPO_INTRFACE
WHERE FWTMP_REGPO_ERR_IND = 'Y')
loop
           utl_file.put_line(f,rpad(NVL('Invoice Number: '||rec.fwtmp_regpo_inv_num,'0'||' '),200)||CHR(13)
           ||rpad(NVL('Fund Error: '||rec.FWTMP_REGPO_ERR_BAD_FUND,'0'||' '),200)||CHR(13)

           ||rpad(('Quantity Error: '||rec.FWTMP_REGPO_ERR_QTY_MORE||'0'),200)||CHR(13)

           ||rpad(NVL('Invoice Error :'||rec.FWTMP_REGPO_ERR_INV_FOUND,'0'||' '),200)||CHR(13)
           ||rpad(NVL('Amount: '||rec.FWTMP_REGPO_INV_AMT,'0'||' '),200)||CHR(13)
           ||rpad(NVL('Po: '||rec.FWTMP_REGPO_PO,'0'||' '),200)||CHR(13)
           ||rpad(NVL('Credit memo: '||rec.fwtmp_regpo_credit_memo,'0'||' '),200)
           ||CHR(13)||'-------------------------------------------------------------------------------------------'||CHR(13));
    end loop;My challenge is simplly how to get the contents of the loop to the b64 variable. Any help would be greatly appreciated.
Thanks

I guess you have never been confused or frustuated. :-). That is why drinking copious amounts of coffee is important.
A simple example of code goes a long way.
SEND_ATTACH_VARCHAR2() call is explained in the documentation. Numerous source code examples can be easily found. Thus my criticism.
The basic concept is - the attachment parameter contains the contents (e.g. file content, text content, image contents) and the filename parameter names that contents.
Keep in mind that the document clearly states that the attachment data types are varchar2 and raw - both which are limited to 32KB. This means that larger attachment sizes will fail and that you need to use UTL_SMTP instead. Which is also documented in the same reference guide. And for which there are also a lot of examples.
