metadata

问题 I have a directory in all_directories, but I need to find out what permissions are associated with it, i.e. what has been granted on it? 回答1: This should give you the roles, users and permissions granted on a directory: SELECT * FROM all_tab_privs WHERE table_name = 'your_directory'; --> needs to be upper case And yes, it IS in the all_TAB_privs view ;-) A better name for that view would be something like "ALL_OBJECT_PRIVS", since it also includes PL/SQL objects and their execute permissions

问题 Where does the convention of using private metadata variables like __author__ within a module come from? This Python mailinglist thread seems to hint at some discussion about it in 2001, but by the sound of it the convention was already out in the wild. Other than that, I can only find this PEP on package metadata, which seems influential but tangental at best. I'd like to try and find some explicit material on the subject so my documentation tool can parse these metadata variables

问题 Is there a good way to tell who created a stored procedure in SQL Server 2005 (that also works in 2008)? In SQL Management Studio I can right mouse/properties on a proc to get the created date/time but how do I discover the creator? 回答1: It may be too late for you now, but you can keep track of DDL activity. We have a table in our administrative database that gets all the activity put in it. It uses a DDL trigger, new to 2005. These scripts create a table in your admin DB (SQL_DBA for me),

I then read here that I need to query the metadata server for this data, but that just returns a 403 unauthorized when run from the instance itself. Is there a way to access metadata as environment variables? 回答1: It may be worth studying Metadata querying a bit more, but my guess is that you

问题 I can get a list of unique constraints fairly easily with the following query: select * from INFORMATION_SCHEMA.TABLE_CONSTRAINTS where CONSTRAINT_TYPE='UNIQUE' But how do I get a list of the columns that each unique constraint applies to? 回答1: See INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE 回答2: Ed is correct, the columns are exposed on the constraint column usage view, here is the SQL for it. select TC.Constraint_Name, CC.Column_Name from information_schema.table_constraints TC inner join

问题 I would like to me able to set (and get) a custom metadata attribute for any file. What is the best way to do this? Thanks 回答1: The OpenMeta framework is a de-facto third-party standard for adding metadata to OS X files using extended attributes.
