Получить подробную информацию из системного каталога в Oracle 11G

Question

Мне нужно найти следующую информацию о всех определяемых пользователем таблиц в одном запросе в Oracle11g:

1. Имя таблицы
2. Имя столбца
3. Constraint имя
4. Constraint Тип - используйте 'ПК', 'ФК', 'СК' и 'NN' вместо 1 буквенные коды
5. Поиск Условия для любого Check (CK) ограничения
6. Таблица и колонки, что каждый FK ссылается

До сих пор мне удалось это:

SELECT table_name FROM user_tables ORDER BY table_name; 

TABLE_NAME

CLIENT 
EMPLOYEE 
FAULTREPORT 
OUTLET 
RAGREEMENT 
VEHICLE

Может кто-нибудь помочь мне? Благодаря!

Ну, вы могли бы просто использовать

SELECT table_name, constraint_name, constraint_type 
    FROM user_constraints 
WHERE table_name IN (SELECT table_name FROM user_tables) 
ORDER BY table_name; 

или

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; 

Это даст вам подробную информацию обо всех таблицах you own.

Теперь, если вы хотите, чтобы сведения обо всех таблицах ваша учетная запись имеет доступ, вы можете использовать

SELECT table_name, constraint_name, constraint_type 
    FROM user_constraints 
WHERE table_name IN (SELECT table_name FROM all_tables) 
ORDER BY table_name; 

или

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: Если вы хотите увидеть все имена столбцов и детали ограничения, если таковые имеются, используйте ниже (непроверенные)

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;
