Problem
A MySQL error occurs when the function "Extract all rows" is used.
Solution
Allow the MySQL user "xcall" to export data into a file in your mysql instance.
Open the SSH console to xCally server and connect to mysql console:
mysql -u root -p(root password) GRANT FILE ON *.* TO 'xcall'@'localhost' identified by 'xcall1234'; GRANT FILE ON *.* TO 'xcall'@'%' identified by 'xcall1234'; FLUSH PRIVILEGES;
end restart the httpd service
service httpd restart
