Please could someone guide me as to how best to write the regex below. The issue I have with it is that someone could write 'dRop' and the regex would not pick it up. 

if ( $_ =~ /$(--|;|DELETE\s|DROP\s|UPDATE\s|EXEC\s|INSERT\s|CREATE\s|d
+elete\s|drop\s|update\s|exec\s|insert\s|create\s)/ ) {
      
    print "There is a possible injection attack here"; ## Security fun
+ction here
    die;
      }

Update: It appears the answer is: 
  if ( $_ =~ /$(--|;|DELETE\s|DROP\s|UPDATE\s|EXEC\s|INSERT\s|CREATE\s
+)/i ) {
    
    die;
      }

But how do I stop the case insensitivity applying to '--' and ';'?
