如何在oracle 11g中查询主键

Question

有谁知道如何在Oracle 11g中查询表的主键？我在SQL Server上看到了类似的问题,但是我在尝试该线程的答案时没有运气.

谢谢!

作为拥有该表的用户,您可以执行以下操作:

select constraint_name, status, deferrable, deferred, validated, generated 
from user_constraints 
where constraint_type = 'P' and table_name = 'Table Name'

更新:我认为这可以满足您的需求.

SELECT cols.table_name, cols.column_name, cols.position, cons.status, cons.owner
FROM all_constraints cons, all_cons_columns cols
WHERE cols.table_name = 'Table Name'
AND cons.constraint_type = 'P'
AND cons.constraint_name = cols.constraint_name
AND cons.owner = cols.owner
ORDER BY cols.table_name, cols.position
