@ -593,6 +593,14 @@ Oracle imposes a name length limit of 30 characters. To accommodate this, the
backend truncates database identifiers to fit, replacing the final four
characters of the truncated name with a repeatable MD5 hash value.
When running syncdb, an ``ORA-06552`` error may be encountered if
certain Oracle keywords are used as the name of a model field or the
value of a ``db_column`` option. Django quotes all identifiers used
in queries to prevent most such problems, but this error can still
occur when an Oracle datatype is used as a column name. In
particular, take care to avoid using the names ``date``,
``timestamp``, ``number`` or ``float`` as a field name.
