Hello James,
Basically the problem I am having is how best to handle multiple values for
a specific column, in this case the values in question are coming from an
HTML SELECT MULTI box processed by PHP.
The way I have been doing this so far is to have a delimited value stored
in a varchar

Hi
It would be great if anyone could help me with a problem in mySQL.
I have 3 tables to describe attributes for a product database.
e.g.

Martin,
there is a bug in 4.0.1 which can make a foreign key definition to fail in
an assertion failure in dict0crea.c, if you have set default-character-set
to something else than latin1 in my.cnf.
Harald Fuchs reported the bug on this mailing list a couple of days ago, and

The above is actually expected behaviour, as you are not doing a join

InnoDB is a MySQL table type which adds transactions, row level locking, and
foreign key constraints to MySQL.
InnoDB is included in the MySQL-Max-3.23.48, MySQL-4.0, and MySQL-Max-4.0
distributions of MySQL. These can be downloaded from http://www.mysql.com.

How does one go about removing one of two identical records in a MySQL
database? My mistake in an earlier database was not applying a unique
number to each record (1, 2, 3, ---). I know it's possible to use the
DISTINCT operator to show only one of the identical records in a result,

If I use a REGEXP query on an indexed column using something like:

Will MySQL use the index like it would if I used Field LIKE 'A%' or Field LIKE

Consultant:
You can do the following to remove duplicates:
- create table foo as select distinct cols from
table_name_containing_duplicates;
- drop table_name_containing_duplicates;
- alter table foo rename to table_name_containing_duplicates;
Done.
Now, make a primay key for the new table!! -- this will
