Thanks in advance!

Hi,
Try this:
UNDEFINE table
UNDEFINE owner
ACCEPT owner CHAR PROMPT 'Enter Owner: '
ACCEPT table CHAR PROMPT 'Enter Table: '
COLUMN y new_value sid NOPRINT
SELECT name||'_'||TO_CHAR(sysdate, 'ddmonyy_hh24miss') y FROM v$database;
SPOOL constraints_&owner..&table..&sid..txt
SELECT a.constraint_name constraint, DECODE(a.constraint_type,
                                                              'C', 'Check',
                                                              'P', 'Primary Key',
                                                              'U', 'Unique Key',
                                                              'R', 'Referential Integrity',
                                                              'V', 'With Check Option',
                                                              'O', 'With Read Only') constraint_type,
       a.index_name, a.owner||'.'||a.table_name table, a.status,
       DECODE(a.r_owner||'.'||a.r_constraint_name,'.',null,a.r_owner||'.'||a.r_constraint_name) rconstraint,
       f.constraint_name fconstraint, DECODE(f.owner||'.'||f.table_name,'.',null,f.owner||'.'||f.table_name) ftable,
       f.status fstatus
FROM dba_constraints a, dba_constraints f
WHERE a.owner = f.r_owner(+) AND
      a.constraint_name = f.r_constraint_name(+) AND
      a.owner LIKE UPPER('&owner') AND
      a.table_name LIKE UPPER('&tabla')
ORDER BY 3,1;
SELECT constraint_name constraint, owner||'.'||table_name||'.'||column_name column, position
FROM dba_cons_columns
WHERE owner LIKE UPPER('&owner') AND
      table_name LIKE UPPER('&tabla')
ORDER BY 1,2;
SPOOL OFF
