I would first try refactoring your SQL to use INNER JOIN statements
instead of the comma separated lists you are currently using. I would also
not use any subqueries. Test this and see if it works for you:

In MS Access, linked tables (not imported tables) are live with the
backend. If you change something in a linked table, that change
automatically propogates to the origin of the link and changes the source
of the data. Try setting up your tables as linked tables and see if it
helps.

Yes, it is a client-side behavior to the extent that the MySQL server does
not page through data. It gets the complete results unless you ask for a
LIMIT, then it stops building results after it meets the criteria of your

You can reproduce that error by writing ...
SELECT ...
FROM a, b INNER JOIN c ON a.x=c.y
The error goes away if you instead write

The Windows DLL is thread safe. You do not have to call my_init()
and my_thread_init() because Windows DLLs receive events when they
are attached to a new process and when they are attached to a new
thread in a process.
The sock file is not a permanent file. It is a socket descriptor that
should only exist if the MySQL server is running and if the server is
configured to supports socket-type connections. Most of the default
installations DO NOT start the server as part of the installation process.

Will you have name collisions with the same temporary table names used
from different connections? Nope.
Temporary tables and user-defined (@-variables) are connection-specific.
Even if the same username/password combination is used to create several
connections, each connection will have its
The CREATE TABLE ... SELECT ... command is all one command. You weren't
supposed to break it up. Sorry if I didn't make that very clear (my

You should probably be on a SCRIPT tab not a QUERY tab if you are running
this through QueryBrowser in order to execute more than one statement

You might try doing exactly what you ask to speed things up. Create a
temporary table to hold the results of an intermediate query from
locations then use the temp table as the source data for the greater
circle calculation. By limiting the distance combinations that need to be

Hi there,
I am wondering if there is a possiblity to delete rows in more than one
table with one query.
At the moment I am doing this:
I do have at the moment 3 querys!:
# get table1_id
SELECT table1_id

You could re-write your query so that you get the lat and lon for each
location as you run the query. Since each location has a zip code, this
just means only one extra join per query. That also means you won't need
the triggers as you are looking up each locations lat and lon on the fly.

So far (check today's archives) not at all. We will have to wait to see
what develops.
Unless you are on a severely underpowered machine, MySQL will handle 3
million rows without any problems. If you are on such an underpowered
machine, then your current process must absolutely CRAWL!!! Don't worry
numbers in the millionsl when you are working with enterprise-quality

Hello.
In my opinion you have two choices (hope someone has better :).
First - you can generate dynamically your query (the IN part
of your query). See definition of the IN operator at:
