如何在Oracle 11g中查询主键 [英] How to query for a primary key in oracle 11g

问题描述

有人知道如何在Oracle 11g中查询表的主键吗?我对于SQL Server看到了类似的问题，但是尝试在该线程上回答问题并没有运气.

Does anybody know how to query for a primary key of a table in Oracle 11g? I saw a similar question for SQL Server, but I've had no luck from trying the answers on that thread.

谢谢！

推荐答案

作为拥有表的用户，您可以执行以下操作:

As the user that owns the table you can do:

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.

Update: I think this gets you what you need.

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
