Hi
I have a problem I need to create recordes with a time stamp that is not
updated when the record is updated. Is this posible or will I have to
manualy create the timestamp using php and insert it when the record is
created ?
Thank you for your time.

Ady,
INSERT into .. SELECT .. would be the largest part of the workload. My
workload is a relatively small number of relatively large operations. Your
reported bug appears to be the other way around.
I am using MyISAM - very large quantities of data - can't afford, and don't
need, transactions.
I dont think it is possible although I have never searched hard for the
ability. It seems unlikely - since you get to name the columns in the table
and the columns in the query (using 'as'). I suggest you use one of those
abilities.

Can you post the failed SQL statement from your altered bin log, and
maybe the preceding commands related to that table?

I have some questions regarding InnoDB indices.

Please explain to me how mysqld's key buffer uses memory under Linux

I'd want to know for sure if every mysqld thread (forked upon an

or key buffer is common for all mysql

If set to 0, no logging is done to the binary log for the client.

I guess I was thinking that if an index with otherwise low selectivity
added a rightmost column that was completely unique that it would
improve key distribution and therefore make

No, unfortunately we have no control over the DELETE queries. The master

Scott,
There were 257 commands related to the table before the error. They all
look the same.
Below are the last two (256th and 257th), followed by the one that
caused the read-only error.

I'm not sure what version of MySQL you're running, but might it be
possible to put a trigger on the tables in the slave DB to insert
deleted records into another table?
I've done such things for large tables that need trimmed from time to
time, but I need to save the old data for archival.
Robert,
actually, InnoDB always internally adds the PRIMARY KEY to every secondary
index record:
http://dev.mysql.com/doc/refman/5.0/en/innodb-table-and-index.html
If a column has just four different values, then in most cases an index on
that column does not help at all. And every index

Mary, you need to know 100% that mysql is actually running
and what port or socket it is listening on for connections,
before you even try and connect to it.
If you call mysqld directly with a script something like:
#! /bin/sh
# start-mysql-5.0.18
#
# start the MySQL database server
Also be careful with this:
http://dev.mysql.com/doc/refman/5.0/en/old-client.html
(after to establish a connection)
Edwin.
