Get details from System Catalog in Oracle 11G - oracle

Question

I need to find the following information on all user defined tables in a SINGLE query in Oracle11g:
Table name
Column name
Constraint name
Constraint type - Use 'PK', 'FK', 'CK' and 'NN' instead of 1 letter codes
Search Condition for any Check (CK) constraints
Table and Column that each FK references
So far, I have managed this:
SELECT table_name FROM user_tables ORDER BY table_name;
TABLE_NAME
---------------
CLIENT
EMPLOYEE
FAULTREPORT
OUTLET
RAGREEMENT
VEHICLE
SELECT table_name, constraint_name, constraint_type
FROM user_constraints
WHERE table_name IN ('CLIENT','EMPLOYEE','FAULTREPORT','OUTLET','RAGREEMENT','VEHICLE')
ORDER BY table_name;
TABLE_NAME CONSTRAINT_NAME C SEARCH_CONDITION

Can someone help me out? Thanks!

Well, you could simply use
SELECT table_name, constraint_name, constraint_type
FROM user_constraints
WHERE table_name IN (SELECT table_name FROM user_tables)
ORDER BY table_name;
or
SELECT UT.table_name, UC.constraint_name, UC.constraint_type
FROM user_tables UT
INNER JOIN user_constraints UC ON UT.table_name = UC. table_name
ORDER BY UT.table_name;
This will give you details about all the tables you own.
Now, if you want the details about all tables your account has access to, you can use
SELECT table_name, constraint_name, constraint_type
FROM user_constraints
WHERE table_name IN (SELECT table_name FROM all_tables)
ORDER BY table_name;
or
SELECT AT.table_name, UC.constraint_name, UC.constraint_type
FROM all_tables AT
INNER JOIN user_constraints UC ON AT.table_name = UC. table_name
ORDER BY AT.table_name;
EDITED : If you want to see all column names and the constraint details if any, use the below (untested)
SELECT UTC.table_name
, UTC.column_name
, UC.constraint_name
, UC.constraint_type
FROM USER_TAB_COLUMNS UTC
LEFT JOIN user_constraints UC ON UTC.table_name = UC. table_name
ORDER BY UTC.table_name;
