That list of words makes me suspect you are writing code which is vulnerable to SQL Injection[^].

NEVER use string concatenation to build a SQL query. ALWAYS use a parameterized query.

Actually I think he's trying to cobble together his own version of protection against SQL Injection.

Well, that's bound to end well! 🤣

If only we could work out the company or service name, so we could keep an eye out for the inevitable massive fine they're bound to be hit with when this home-brew "protection" doesn't work.
