Hi folks,
I'm new with MySQL and I'm really impressed by this database engine.
While waiting for Stored Procedures :) (ver 5: anyone can say when
will be, approximately, released?), due to the fact that I'm coming
from MSSQL world, can anyone tell me if there's a way to perform join
without the classic SQL statement (inner join on, right join on, etc)
but using the WHERE clause, with equal =(inner join), star-equal *=
(left join) and equal-star =* (right join)?
Example follows:
SELECT
A.FIELD_1, B.FIELD_2, C.FIELD_3
FROM
TABLE_1 A, TABLE_2 B, TABLE_3 C
/* Here i go with joins using equals */
WHERE
A.KEYFIELD = B.A_KEYFIELD
AND A.KEYFIELD = C.A_KEYFIELD
I found this way on MSSQL very powerful and I'd like to produce the
same clean-code here with MySQL..
TIA, tK

Hi!
I identified a bottleneck in my programs.
I just want to "encrypt" data by easy xoring. Ok - that's no
encryption at all - I know. But it's hardly readable - and that's
enough :-) Just some quick obscurity.
It turns out not to be quick at all. I really didn't expect this to be
a bottleneck, but it takes quite some time.

I've done some Googling around on this and it seems like creating a here
document is a bit tricky with Python. Trivial via triple-quoted strings
if there's no need for variable interpolation but requiring a long, long
formatted arglist via (%s,%s,%s,ad infinitum) if there is. So my
question is:
Is there a way to produce a very long multiline string of output with
variables' values inserted without having to resort to this wacky

Should be easy, but I've been trying to figure this out for about half

column.
On with the problem. If i do SELECT * FROM Cybex, it lists the 1000 or

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.
