I am using Oracle 11.1 I have this plsql block which sends perfectly fine email with .csv attachment.
But I want to zip it and send. When I change the file extension as .zip, email comes fine as Report.zip ,but I cannot open the zip file, it says corrupted. How do I compress?
DECLARE

crlf VARCHAR2(2) := chr(13)||chr(10);
v_date VARCHAR2(15) := TO_CHAR(TRUNC(SYSDATE) -1,'MM_DD_YYYY');
