Your IN clause placeholder will only work if there's one value. You either have to dynamically create the query so the number of IN placeholders matches the number of IN bind parameters; or you have to dynamically create the IN clause to expand to what you want.

There's a decent thread on this here that has examples.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
