When I do desc table, I get back the columns Name, Null? and Type. What I also wish to get back is a column like UNIQUE to tell me if the column is in fact unique. I realize that this is a combination of columns labeled UNIQUE with the column (if present) labeled as the primary key for that table.
As an alternative, I have tried:
SELECT column_name "Name", nullable "Null?", concat(concat(concat(data_type,'('),data_length),')') "Type" FROM user_tab_columns WHERE table_name='TABLE_NAME_TO_DESCRIBE';
which I found somewhere, however I get 0 rows returned when I replace the TABLE_NAME_TO_DESCRIBE with the name of my table.
I am running from sqlplus. Any way to accomplish this? Either specific (returning of UNIQUE constraint) or general (how to alter desc command results) answers appreciated.
