It's highly, highly unlikely that DBI is the culprit. DBI doesn't interpret the SQL you pass through.

Does your query work if you run it directly against the database (using mysql or sqlplus or whatever command-line tool applies to the platform you're using)? If the tables are huge, your query could take a very long time to process.

Just as an aside, it's stylistically nicer to put your search conditions separately from your join criteria, such as:

SELECT COUNT(*) FROM theTable A INNER JOIN theTable B ON A.column_2 = B.column_2 WHERE A.column_1 = ? AND B.column_1 = ?
Also, notice I changed your string interpolations to placeholders. If your driver supports it, placeholders are definitely the way to go.

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.
