your function MySpecialFunction() will recieve the following string:
"SELECT * FROM tblname WHERE 4=Yo AND WHERE 3=Man"
which apart from being (probably) incorrect SQL, is just a string -
how is your special function supposed to tell which chars are part of
the previously injected variables' values - and even more impossible:
how would the function find out what those variables we're called to
begin with (it can't).
what is it you would like to achieve?
