Re: Security for web site accessing i via IWS

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.
