Other reply s accurate but it's always a good practice to include the semicolon else you can get

"Bobby tables'ed" look that xkcd comic up

I'm not sure how including a final semicolon can protect against an injection attack. In fact, the "Bobby Tables" attack specifically adds in a semicolon, to be able to start a new command. If inputs are sanitized, or much better, passed as parameters rather than string concatenated, you should be fine - nothing can be injected, regardless of the semicolon. If you concatenate untrusted strings straight into your query, an injection can be crafted to take advantage, with or without a semicolon.

Yep it would only work if you didn't sanitize a user input string in this case 'nice'

They could write ''; drop table blah;

Wouldn't that still apply, if you can inject straight SQL, such as "query' OR 1=1?"
