Your data should be escaped in the DB. Your MySQL driver should be handling the escape/un-escape when setting/retrieving the data. A friend pointed out to me today: In the earlier versions of PHP there was a setting called 'magic_quotes_gpc'. When enabled slashes were added by default. This setting has since been depreciated as of PHP 5.3 and was removed completely in PHP 5.4. I am using PHP 5.6. Thank you for the suggestion of running 3 separate commands. Individually these execute successfully. Is it even possible to do a REPLACE in the fashion I have noted? Ron
