in thread DBI Parameter Security
As long as you're using placeholders (and the DBI layer doesn't shortcut them), tehre is no way that data will leak through as commands to the database.
Turning on DBI tracing you can see exactly what is happening
You can from the trace see how the commands are passed to the database seprately from the data (using mySQL in this example). The DB is smart enough to not treat data as executable sql code.<- prepare('select * from foo where bar=?' CODE)= DBI::st=HASH(0x81a25 +74) at testph.pl line 11. <- execute('plugh' CODE)= 1 at testph.pl line 12.
