SQL & PL/SQL

Dear experts,

I want to see table constraint information from sql plus. Is it possible to see.

SQL>desc test   --is showing only Not Null information

e.g.

SQL>create table test(cunique number(2,0) constraint c_unique unique,ccheck number(3,0) constraint ccheck check(ccheck between 500 and 999));

SQL> desc test;

Name                                      Null?    Type

----------------------------------------- -------- ----------------------------

CUNIQUE                                            NUMBER(2)

CCHECK                                             NUMBER(3)

I want to see all the constraints (like check - 500 and 999))) applied on table.

regards,

Pardeep
