Considering the query uses '?', i assume it is a placeholder. It seems that he is executing the query with a single value a number of times, and after each run he does something with the returned values.

Afterward, he has an array of IDs @queryIDs. He wants to execute the the same query (and gather the results in order) for the values in the array.

This is actually a SQL question, and the answer is, it depends. The quick and dirty (and insecure) method is to join the array with commas and build a dynamic SQL statement with IN().

To do the same securely, would require splitting the list in SQL, which depends on the RDBMS and version. For example, Oracle 11r2 has a good tokenization method via XMLDB which can be found with a simple search.

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 How to display code and escape characters are good places to start.
