phpmyadmin access problem

All of a sudden I started to get the following error:

#1045 - Access denied for user 'root'@'localhost' (using password: NO)

whenever I tried to access to mysql database through phpmyadmin. I have been using it flawless for very long time.

I modified the following file:

/var/lib/phpmyadmin/config.inc.php

by changing

$cfg['Servers'][$i]['auth_type'] = 'config';

to

$cfg['Servers'][$i]['auth_type'] = 'cookie';

and everything is working fine now.

Perl DBI – Some usefull commands

Return a reference to column names

$name = $sth->{NAME};

Number of affected rows

$sth->rows();

New auto-incremented id

$latestId = $dbh->{‘mysql_insertid’}

Uploading large data. ‘INSERT INTO’ command takes long amount of time. Use ‘LOAD DATA’ command to upload bulk data from a text file.

• Be careful. If the file to be uploaded resides on the server, it still needs to be accessible by the mysql server. E.g. you can place them under /tmp
• You can specify NULL characters by ‘\N’, e.g. “9,\N,276,John…”
