SQL injection attacks


Also has to be said that if you must generate programming-language statements on the fly, then you need to convert strings in to string literals anyway. For SQL this means doubling up all the apostrophes (in case someone's log-in name is o'reilly), and then SQL injection should not be possible...

My preference has always been for the application to do all its work via stored procedures; you can then give the database user the applciation connects as no INSERT or UPDATE privileges at all.
