title: Crystal reports and MySQL - unable to use left outer join
body: <p>I have recently installed Crystal reports 2011 version 14.0.2.364 RTM.  I am connecting to a MySQL database having created a DSN using the MySQL ODBC 3.51 driver.  I am able to create reports using individual tables or right joins, however, when I try creating a report using a left join Crystal freezes and I have to force the program to quit.  </p>
  
  <p>The timeout settings on MySQL server are set to 30 minutes so this does not appear to be the issue.  Using Microsoft SQL Server Management Studio and accessing the same database as a linked server the query takes 1 minutes 18 seconds to return 1,380,993 rows.</p>
  
  <p>I cannot work out why Crystal is unable to perform the query/return results when the SQL query executes fine.  Please let me know if you need any further information.</p>
  
  <p>query in crystal</p>
  
  <pre><code> SELECT `applications1`.`id`, `application_statuses1`.`status`
   FROM   `js_reporting`.`applications` `applications1`
    LEFT OUTER JOIN `js_reporting`.`application_statuses` `application_statuses1` ON `applications1`.`id`=`application_statuses1`.`application_id`
  </code></pre>
  
  <p>same query in SQL server</p>
  
  <pre><code>select applications.id, application_statuses.status
  from mysql_js...applications
   left join mysql_js...application_statuses on applications.id=application_statuses.application_id
  </code></pre>
