Reread the 'dynamic' SQL above. Note that the dynamic component is the number of placeholders, and so there is no attack surface exposed. There are safe and robust ways to do dynamic SQL; it's just always important to understand how to fundamentally limit what could possibly be included. I expect your proposal would bypass the Perl escaping layer entirely, thus increasing the number of attack vectors.

<pedantic>Technically, there is additional attack surface, since you could create some kind of denial of service based upon a really long query, but that's really getting into the weeds.</pedantic>


#11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
