Hello,
I need to extract DDL statement create table from a database (reverse engeneer) and for this I need to get default value of a column .
This piece of information I get from field data_default (Long datatype) from all_tab_columns .
I need to read this field .
Please tell me , how I do this? (read a Long datatype and convert it to varchar2)
Many thanks,
Aurel
