I don't have any idea about your second question but I have a thought on the
first one.
In DB2, which I use most of the time, you don't need to qualify a column
name like list_ID or acct_ID unless it is ambiguous. In this case, neither
one is ambiguous because both get used in single-table SELECT

You did not show us your actual insert statement, but
You can not insert into a table listed anywhere in the select.

somewhere on mysql.com is said:

Take a look at:
http://www.mysql.com/doc/T/O/TODO.html and
http://www.mysql.com/doc/A/N/ANSI_diff_Sub-selects.html
You can do what you want to do easily by using an API (PHP, Perl, etc.) Is
it possible for you to use an external program, or does it have to be SQL
only?

i have to use a statement like:
SELECT CODICE FROM TABSIC WHERE COM=1 AND SEN=1 AND PRI=1
AND CODICEALL(SELECT CODICE_TABSIC FROM ARCHIVIO_SICU_MIN WHERE
(CODICE_ARCHIVIO=342))
but mysql doesn't support
Try the following:
SELECT leads.* FROM leads
LEFT JOIN blacklist ON leads.refnumberid = blacklist.leadid
WHERE blacklist.leadid IS NULL
AND ...
The LEFT JOIN will give you a row for every row in leads; blacklist columns
will be null if there's no matching blacklist, so the WHERE
no, but you can acheive the same results

This is how I'd like the query to work:
insert into host (host_id, host_IP) values ((select from mail
mail_id where
mail_addr = [EMAIL PROTECTED]), '127.0.0.1')
Try:
insert into host (host_id, host_IP) select mail_id, '127.0.0.1' from mail
where mail_addr = '[EMAIL PROTECTED]';

I?m wondering if there is planned support for Sub-Selects
(e.g. HAVING and so on) in upcoming versions? I think
this is very important to implement.

Hi!
It will come in version 4.1.
Hi Eric,
I'll second Bob Hall's opinion.
One could extend a query so that it checks also your additional condition.
You haven't gotten to the 'group by' and 'having' goodies, that's the hint.
But this would make it over-complicated,
and MySQL could run into problems when attempting to evaluate
