Enter a URL something like this in your browser
http://yourmoodle/mod/scorm/report.php?id=36&mode=interactions&tifirst=A

Where 36 is the id of a scorm package

This generates following errors
Alternatively

1. Goto Scorm > reports > interaction
2. set Show to "all users"
3. set page size in such a way that you get atleast 4-5 pages of results
4. Select an option from the firstname/lastname (Any character A,B,C,D)

   ERROR: Mixed types of sql query parameters!!

   Stack trace:

   line 711 of \lib\dml\moodle_database.php: dml_exception thrown

   line 804 of \lib\dml\mysqli_native_moodle_database.php: call to moodle_database->fix_sql_params()

   line 1297 of \lib\dml\moodle_database.php: call to mysqli_native_moodle_database->get_records_sql()

   line 85 of \mod\scorm\report.php: call to scorm_interactions_report->display()

Reason of this is both "?" and ":varname" type of wildcards are used in the report

Note: the same changes should also be applied to basic report, so that it doesnt break when MDL-28588 will land.
Thanks
