A query longer than 65535; this will be truncated when saved.
The field saved_sql.savedsql is type 'text', which is 65535 characters long.
mysql> select table_name, column_name, data_type from
information_schema.columns where column_name = 'savedsql';
+------------+-------------+-----------+
| table_name | column_name | data_type |
+------------+-------------+-----------+
| saved_sql | savedsql | text |
+------------+-------------+-----------+
The query editor in guided_reports.pl does not check the size of the report
being saved, causing the report to be truncated if its more than 65535
characters long.
I would suggest changing the data type of savedsql to LONGTEXT, then limiting
the query length to something fairly large, but less than 4,294,967,295
characters, with a warning (to avoid denial of service by filling the hard
drive).
