Create a report from 2 forms

Could you export the two forms as two CSV files and then manage/manipulate the data? We don't have a database schema available. The tables that store entry data are the _rg_lead tables. I hope that helps.

Here is what we use in export.php -

$sql = "SELECT d.field_number as field_id, ifnull(l.value, d.value) as value
                    FROM {$wpdb->prefix}rg_lead_detail d
                    LEFT OUTER JOIN {$wpdb->prefix}rg_lead_detail_long l ON d.id = l.lead_detail_id
                    WHERE d.form_id={$form["id"]} AND cast(d.field_number as decimal) IN ({$field_ids})
                    LIMIT {$offset}, {$page_size}";
