Hi!
Using Union and Order By gives strange behaviour in the following test-case:
drop table if exists gallery;
drop table if exists gallery_categ;
# create test tables
create table gallery (d_image_small char(100), d_image_big char(100));
create table gallery_categ (d_image char(100));
# insert test data

int *ip = &u.i;
U *up = static_cast<U *>(ip); // error
I have to change the cast to reinterpret_cast for the code

I previously posted about a problem where it seemed that changing the
case of the word "BY" in a SELECT query was causing it to run much much
faster.
Now I've hit the same thing again, where basically almost any change I
make to how the query is executed (so that it still performs the same
function) causes the performance to jump from a...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...
