USEFULL FUNCTION WITH WEB APPLICATIONS

Hi guys again
reading my old mysql feature requests i read about a interesting and very very used function
BASE64_ENCODE and BASE64_DECODE
this is very usefull with files to store than using a text free of sql injection and a very bad compression but usefull
check here http://bugs.mysql.com/bug.php?id=18861
the function is used in mysql client code, but not appended to mysql server, it can be done at client side but use a lot of network (when using BASE64_DECODE function, for BASE64_ENCODE is just needed when update/insert)
there´s a sql implementation and a pluging available at google and dev team, but they aren´t fast, and the plugin is a bit old
well if it´s still nice to implement....
