a primary key is always unique. No need to give it an extra unique index.

Hello mysql,
Resently MYSQL have introduced transaction support, which at least
in INNODB allows to make consistent backup/recovery. The bad thing
about this is - MYSQLDUMP does not support anything about this, so I
had to done the same things buy hands.
The Idea is quite simple - to

Hi there
I am using the same setup as yourself, but developing with MYVBQL.dll which
is a DLL that some kind fella put together for dummies like me. Works well
and very similar to ADO, couple bugs that I have picked up, but there are
workarounds.
Check the MYSQL web site for the download.

where in the manual does it explain how to set up the root password
after an install? i understand that should be the first thing done.
as the admin of mysql on my server, should the only method i use to
login be by root and said password? OR should i make another
username/password for myself

No.
To load a NULL value into a column using LOAD DATA, you must use \N.
NULL, with or without quotes, will insert as the word "NULL".

When you issue a consistent read, that is, an ordinary SELECT
statement, InnoDB will give your transaction a timepoint according
to which your query sees the database. Thus, if transaction B deletes
a row and commits after your timepoint was assigned, the you will
not see the row deleted. Si

I am having trouble with DBI. I wrote a little script that should update

The index will automatically be used if you use it in your WHERE clause in
that order. If you want to do fulltext searching on those columns, repeat
the query with FULLTEXT in place of UNIQUE.
