Yes, the sql_yacc.y is used to generate the sql parser. The
parser is used more to run the sql rather than to break it into its
tokens. Using the lex files would be closer to your stated goals. The
file lex.h in the same directory as sql_yacc.y contains all the tokens
mysql uses to break

I have one question. MySQL is better than Oracle or not?
Thank you.

Hello,
I've got a table with articles and a table with categories. Using a

Did we already talk about the log flush method you're using with
InnoDB? I don't recall...
Log flush method? As described by Mysql documentation:

If you can afford the loss of some latest committed transactions, you
can set the `my.cnf' parameter |innodb_flush_log_at_trx_commit| to

Hello all,
We recently upgraded to 4.0, it went
very well and the performance gains have been great.
But now the server has started to act strangely. Every few days, the
server starts to refuse connections, saying
that there is already more than max_user_connections, but there is really

On the other hand one could use intervals for key assignment.
Every time a server runs out of keys it throws a warning at the admin
and rejects further inserts until it gets a new key interval.
It's a way to go at least with a low number of servers.
Maybe even give a warning
Hi Jeremy,
Sorry, it seems like I'm saying this a lot lately. Is it not true that
if the whole table will fit in [free] RAM, that the OS will cache the
file data and there is no need for a RAM disk. I don't really see how
performance would be any different than using a RAM disk. Either way,
you
* Roger
Maybe even give a warning some time _before_ you run out of keys...? ;)
You should never run out of keys. Every time you sync, you also check if
there are many keys left to use... if you sync once a day, as soon as you
have less than 10 times the expected daily usage of keys left to use,

I am hoping someone here might have an idea how to set up a complex query I
have been trying to figure out.
Basically I have a table that contains 3 types of records. Property
managers, buildings and tenants. They are related upon insert by an ID and a
PID (parent id). For example :
ID PID
have you try left join?
select
mgr.company,
building.bldgname,
tenant.id
from
customers mgr
left join customers building on building.pid=mgr.id
left join costumers tenant on tenant.pid=building.id
group by mgr.id, building.id, tenant.id
order by mgr.company, building.bldgname, tenant.company
