By default, MySQL is enabled with strict_mode ON, which will most likely cause problems with older PHP applications written for MySQL 4. For example, strict mode will return an error on insert statements if an empty string is provided where an integer is expected.
You may disable strict mode in one of two ways:

you can run the following in phpMyAdmin

SET @@global.sql_mode="";

or Open your “my.ini” file within the MySQL installation directory, and look for the text “sql-mode”. Find:

# Set the SQL mode to strict
 sql-mode=”STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER, NO_ENGINE_SUBSTITUTION”

and change to

# Set the SQL mode to strict
sql-mode=”NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION”

Linux Chown Command Examples to Change Owner and Group

---

The concept of owner and groups for files is fundamental to Linux. Every file is associated with an owner and a group. You can use chown and chgrp commands to change the owner or the group of a particular file or directory.

In this article, we will discuss the ‘chown’ command as it covers most part of the ‘chgrp’ command also.

1. Change the owner of a file

$ls -l filename
-rw-r--r-- 1 srinu chilukuri 0 2013-10-16 20:03 filename

$ chown root filename

$ls -l filename
-rw-r--r-- 1 root chilukuri 0 2013-10-16 20:05 filename

So we see that the owner of the file was changed from ‘srinu’ to ‘root’.
