When we restore a course that has calendar events we get the following...

The data types ntext and varchar are incompatible in the equal to operator.
SELECT * FROM mdl_event WHERE courseid=32 AND name='Cert IV Civil Construction Design - Block1' AND description='' AND timestart=1242858600

line 686 of lib\dmllib.php: call to debugging()
line 481 of lib\dmllib.php: call to get_recordset_sql()
line 531 of lib\dmllib.php: call to get_record_sql()
line 3671 of backup\restorelib.php: call to get_record_select()
line 8008 of backup\restorelib.php: call to restore_create_events()
line 51 of backup\restore_execute.html: call to restore_execute()
line 175 of backup\restore.php: call to include_once()

The problem is line 3671 of backup\restorelib.php, the call to get_record_select(), the description field is ntext, and MSSQL doesn't like the equal to operator.

If I change that line to use the LIKE operator it works ....

"courseid={$eve->courseid} AND name='{$eve->name}' AND description like '{$eve->description}' AND timestart=$eve->timestart");

But I know this is not the correct way to have this fixed...
