Two days in, and I still can't find the cause of this 1064 error.

I have some DB experience, new to MariaDB. Writing a procedure, but always getting error 1064 iff I use a begin/end block. What am I missing? This code, no problem:

delimiter //
create procedure do_easy ()
select category, leaf_match from reportDef
      where ignore_me = false and leaf_match is not null //
delimiter ;

But, this always gives the 1064 error, always saying "............. for the right syntax to use near '' at line 5"

delimiter //
create procedure do_notEasy ()
begin
select category, leaf_match from reportDef
      where ignore_me = false and leaf_match is not null;
end //
delimeter ;

All I did above was add the begin/end block.

Here's the actual code I'm having the problem with...

delimiter //

create procedure do_leafs ()
modifies sql data
begin 
  declare done boolean;
  declare cur_leafs cursor for
    select category, leaf_match from reportDef
      where ignore_me = false and leaf_match is not null;
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;
  open cur_leafs;
  done = false;

leafs: loop
  fetch cur_leafs into category, leaf_match;
  -- if done then
    -- leave leafs;
  end if;
  insert into report values (false, category,
    select sum(amount) from WFChkData where regexp_instr(description, leaf_regexp));
-- future: tag the matched wfchkdata rows
end loop;

close cur_leafs;

end //

delimeter ;

Thanks!
