重传授权验证HAS_TABLE_PRIVILEGE失败

Question

我正在与具有组、架构、默认权限的Redshit授权进行斗争。当我尝试检查是否一切都是正确的使用HAS_TABLE_PRIVILEGE

select tablename, 
   HAS_TABLE_PRIVILEGE('analyst', tablename, 'select') as select,
   HAS_TABLE_PRIVILEGE('analyst', tablename, 'insert') as insert,
   HAS_TABLE_PRIVILEGE('analyst', tablename, 'update') as update,
   HAS_TABLE_PRIVILEGE('analyst', tablename, 'delete') as delete, 
   HAS_TABLE_PRIVILEGE('analyst', tablename, 'references') as references 
from pg_tables
where schemaname='datalab'
order by tablename

我明白了：

An error occurred when executing the SQL command:
select tablename, 
   HAS_TABLE_PRIVILEGE('analyst', tablename, 'select') as select,
   HAS_TABLE_PRIVILEGE('analyst', tablena...

[Amazon](500310) Invalid operation: relation "dss__transaction" does not exist;

Execution time: 0.2s
1 statement failed.

这里到底发生了什么？

Answer 1

我尝试了这一点，pg_tables的第一个结果查询失败了。在我的例子中，这是因为我需要显式地声明每个表在哪个模式中。这对我起了作用：

WITH cte AS 
(
SELECT schemaname+'.'+tablename AS table_name
FROM pg_tables
WHERE schemaname = 'datalab'
)
SELECT table_name, 
   HAS_TABLE_PRIVILEGE('analyst', table_name, 'select') AS select,
   HAS_TABLE_PRIVILEGE('analyst', table_name, 'insert') AS insert,
   HAS_TABLE_PRIVILEGE('analyst', table_name, 'update') AS update,
   HAS_TABLE_PRIVILEGE('analyst', table_name, 'delete') AS delete, 
   HAS_TABLE_PRIVILEGE('analyst', table_name, 'references') AS references 
FROM cte
ORDER BY table_name ASC;
