      Hi Petr, yet another issue with SELECT DISTINCT combined with TEXT fields under Oracle/MSSQL was reported by fweiss in MDL-22910

      I have tracked it down to the code in enrol/meta/locallib.php in user_unenrolled() function:

              $sql = "SELECT DISTINCT e.*
      		 
                        FROM {enrol} e

      The table

      {enrol}

      contains customtext1 and customtext2 TEXT fields that can not be used in this query.
