Hi Peter,
I just tried it on a table with 10 rows and it works fine on 4.0.15.
Have you already tried on a small table?
How many rows is your WHERE clause matching when it's not using the
index? Do you know that MySQL won't use an index if it thinks it will
find more than about 30% of all rows?

if you are using mysql on web (which is the most possible case, as MySQL is
created to be used on web), you can use your scripts to create tamporary
tables and use them as views. else you can write procedures for that
purpose, depending on your need.

Hi Group,
I am wondering whether MySQL is planning to implement Group based privileges.
To make my question clear, consider a database where some users are not allowed to
update data and other are allowed to update. Will it be possible to create a group
that has got some privileges and whenever
-p without the passwd immediately following is not compatible with
input redirection.
Either add the password after the -p with NO space, or better yet,
create a .my.cnf file in the home directory of the user running the script
and have it contain the user and password settings.

Well the issue wasn't so much with my program at runtime, but at design time

Hi Peter,
I don't know what your multiple languages are, but remember that
full-text indexing doesn't currently work with multi-byte character
sets.
Anyway, the built in stopword list is in the myisam/ft_static.c file
of the source code. This is mentioned in the manual for SHOW VARIABLES:
Hi Randy,
Unique keys are not disabled with DISABLE KEYS -- so the unique
constraint isn't violated. From

ALTER TABLE ... DISABLE KEYS makes MySQL to stop updating *non-unique*
indexes for MyISAM table.
