I just added a user variable @fdata to get visabilility outside of the procedure and this is what I get.

I noticed that if I have binary data and I: select data>>1; I get 0 (not what I'm expecting). Here is a test procedure I wrote: create procedure test20 () BEGIN DECLARE fdata BLOB; DECLARE foffset INT UNSIGNED; DECLARE flength INT UNSIGNED; DECLARE tmp_int BIGINT UNSIGNED; SELECT 0xABCDEF0123456789 INTO fdata; SELECT 14 INTO foffset; SELECT 7 INTO flength; SELECT SUBSTR(BINARY(fdata), FLOOR(foffset/8)+1, CEIL((flength + (foffset %8 ))%8)) INTO fdata; SELECT HEX(fdata); SELECT CONVERT(fdata,BIGINT) INTO tmp_int; SELECT HEX(tmp_int); END The last two selects are added to show what I would like to do, but have not been able to get it to work. Any help would be great. Thanks in advance. Accomplishing the impossible means only that the boss will add it to your regular duties.
