> Oracle translator seems to support translation of patterns from SimpleDateFormat to oracle's patterns [1], but not for all of them [2]. If Teiid is not able to translate format then it retrieves date/time/timestamp field and format it [2]. However, if pattern ends with non-pattern/non-letter character, pattern is translated only partially and passed to Oracle DB [3] - I have tried number, *, /, \, etc. Similar behavior with postgresql translator
