It doesn't necessarily require a semi-colon. For example, if concatenating column names into a select statement, someone could potentially inject a sub-select so they could view information that they otherwise wouldn't have access to.

As has already been said here... making sure variables are only inserted via host vars for static statements, or parameter markers for dynamic statements is an easy way to protect against injection attacks.

the end to make any of the original SQL a comment.
