show table dbc source - forum topic by rcef350

what DBC table(s) does the  partition infomation come from when I do a show table?  ex:
PRIMARY INDEX NUPI_mytable_15 ( col1,col2,START_DT)
PARTITION BY ( RANGE_N(START_DT BETWEEN DATE - 15 AND DATE + 140 EACH INTERVAL '1' DAY ),
RANGE_N(START_H BETWEEN 0 AND 23 EACH 1 ) );
