I've also been painfully made aware that my search terms (@q_names) are being quoted, irrespective of SQL's datatype for this field, or of the data in my field. As an example:

SELECT `status`, `rma_num`, `auth_id`, `vendor`, `part_num` FROM rma_l
+ist WHERE ('status') = ('0');

is now being generated, which returns 0 rows, as status is an integer. My code for $query has been extrapolated from your elegant example as:

my $query = "SELECT "
    . join(", ", map { $dbh->quote_identifier($_) } @q_return)
    . " FROM rma_list WHERE ("
    . join(', ', ('?') x (keys %q_search))
    . ") = ("
    . join(', ', ('?') x @q_names)
    . ");";

It seems obvious to me that my code isn't placing these quotes on the search items, so I guess DBI's substitution is. Is there a way to force this off for integer only variables? Or a different substitution character?

• 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).
