email - Oracle UTL_STMP - no content -

i send emails on oracle database via utl_smtp. daily emails sent automatically.

but on days there no content in email , blank mail sent.

this code:

c := utl_smtp.open_connection(smailserver); utl_smtp.helo(c, smailserver); utl_smtp.mail(c, sfrom); utl_smtp.rcpt(c, srecipients); utl_smtp.open_data(c);  utl_smtp.write_data(c, 'to: ' || srecipients || utl_tcp.crlf); utl_smtp.write_data(c, 'from: ' || sfrom || utl_tcp.crlf); utl_smtp.write_data(c, 'subject: ' || replace(sdescr, '[date]',to_char(sdate,'dd.mm.yyyy')) || utl_tcp.crlf); utl_smtp.write_data(c, 'content-type: text/html;' || utl_tcp.crlf);  -- write data       utl_smtp.write_data(c, sdata);  utl_smtp.close_data(c); utl_smtp.quit(c); 

the answer put line between header-data , body-data:

utl_smtp.write_data(c, 'content-type: text/html;' || utl_tcp.crlf);  -- line between header , body utl_smtp.write_data(c, utl_tcp.crlf);   -- write data utl_smtp.write_data(c, sdata);
