No, I didn't shut down mysqld or read lock. Would you please elaborate it a
little more on why? Thanks a lot!

Hi,
I am running MySQL 4.1.8-Max-log on two Linux
But while I copied all the table files from A (testing machine) to machine
B (real server), no data was writing into A's tables.Are you saying
that I have to shut down the mysqld on machine A or activate WRITE lock to
A before copying over to machine B?

Warnings: 2
However, if I put the same command into a file and run mysql command-line,
no warning or any message was given. I have no idea if there is anything
wrong or how many records got changed.
$ mysql -p DB test.sql
Is there any way I can show the warning and message?
Thanks!
Qunfeng
Paul,
Thanks for your reply. I tried
mysql -p -w DB test.sql
still no warning.
I tried -vw
it simply echo the sql statement, no warning.

Hi,
I am running 4.1.0-alpha on a linux machine. When I use mysqlimport to load
a big data file (~7 Gb), I get an error mysqlimport: Error: The table
'mytable' is full, when using table: mytable.
I guess the table is too big. Is there any solution for this problem?
Thanks a million!

Hi,
MySQL seems to be able to JOIN columns with different types, e.g., one
column type is int; the other type is varchar. My question is: how badly
does that affect the join performance even though both columns are indexed.
Thanks!

full text search is different than pattern match. If
you want to return stef, you have to use pattern
match.

Am I missing something on mysql full text search?
I was using a simple statement like
select firstname from contacts where
It can perform pattern match on text field. The only
draw back is the speed (especially if you are using
%pattern% to do the search) when you tables are
getting huge, since there is no index to help.

you can still use fulltext search for general cases;
and use pattern match ONLY when you are searching for
3-char-term. You should be able to make such Switch

Do you
Isn't NULL value in MySQL stored as '\N'? If so, you
can check that in your perl script.
