no reply because u can get these information in documentation easily. but i think u don't want to try hard. any way -
this information comes from dba_tab_columns. it is for backward compatibality with orace7.
low_value - low value in that particular column
high_value - high value in that particular column
you have missed out the column name in your output. the information stored is in raw format . hence 'C102' . you can check this by -
select min(column_name) from table_name
select rawtohex(yourvalue) from dual;
you will get C102 .
