Question

我需要在Oracle11g的SINGLE查询中找到有关所有用户定义表的以下信息：

表名
列名
约束名称
约束类型 - 使用＆＃39; PK＆＃39;，＆＃39; FK＆＃39;＆＃39; CK＆＃39;和＆＃39; NN＆＃39;而不是1个字母代码
检查任何检查（CK）约束的条件
每个FK引用的表和列

到目前为止，我已经设法了：

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;

有人可以帮帮我吗？谢谢！

好吧，你可以简单地使用

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

或

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;

这将为您提供有关所有表you own的详细信息。

现在，如果您想了解您的帐户有权访问的所有表格的详细信息，可以使用

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

或

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;

已编辑：如果您想查看所有列名称和约束详细信息（如果有），请使用以下（未经测试的）

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;

从Oracle 11G中的系统目录中获取详细信息
