Some go further and URLEncode *every* character (so DECLARE becomes
%44%45%43%4C%41%52%45) to get around people checking for "SELECT",
"EXEC", etc

However if you use the 300 using a parameter that's configured as an Int
- it should never hit the database anyway (so if you are using
parameterised queries, you probably need to look elsewhere)
