我想查看关于红移的补助金。
我发现this view for postgres:
CREATE OR REPLACE VIEW view_all_grants AS
SELECT
use.usename as subject,
nsp.nspname as namespace,
c.relname as item,
c.relkind as type,
use2.usename as owner,
c.relacl,
(use2.usename != use.usename and c.relacl::text !~ ('({|,)' || use.usename || '=')) as public
FROM
pg_user use
cross join pg_class c
left join pg_namespace nsp on (c.relnamespace = nsp.oid)
left join pg_user use2 on (c.relowner = use2.usesysid)
WHERE
c.relowner = use.usesysid or
c.relacl::text ~ ('({|,)(|' || use.usename || ')=')
ORDER BY
subject,
namespace,
item
这不起作用,因为
::text
的relacl
强制转换失败并显示以下内容:ERROR: cannot cast type aclitem[] to character varying [SQL State=42846]
将查询修改为
CREATE OR REPLACE VIEW view_all_grants AS
SELECT
use.usename as subject,
nsp.nspname as namespace,
c.relname as item,
c.relkind as type,
use2.usename as owner,
c.relacl
-- , (use2.usename != use.usename and c.relacl::text !~ ('({|,)' || use.usename || '=')) as public
FROM
pg_user use
cross join pg_class c
left join pg_namespace nsp on (c.relnamespace = nsp.oid)
left join pg_user use2 on (c.relowner = use2.usesysid)
WHERE
c.relowner = use.usesysid
-- or c.relacl::text ~ ('({|,)(|' || use.usename || ')=')
ORDER BY
subject,
namespace,
item
允许创建 View ,但是我担心这不会显示所有相关数据。
如何修改 View 以在redshift上工作,或者是否有更好的/替代方法来查看redshift上的授权?
更新: Redshift具有HAS_TABLE_PRIVILEGE函数来检查授予。 (请参阅here)
最佳答案
另一个变化是:
SELECT *
FROM
(
SELECT
schemaname
,objectname
,usename
,HAS_TABLE_PRIVILEGE(usrs.usename, fullobj, 'select') AND has_schema_privilege(usrs.usename, schemaname, 'usage') AS sel
,HAS_TABLE_PRIVILEGE(usrs.usename, fullobj, 'insert') AND has_schema_privilege(usrs.usename, schemaname, 'usage') AS ins
,HAS_TABLE_PRIVILEGE(usrs.usename, fullobj, 'update') AND has_schema_privilege(usrs.usename, schemaname, 'usage') AS upd
,HAS_TABLE_PRIVILEGE(usrs.usename, fullobj, 'delete') AND has_schema_privilege(usrs.usename, schemaname, 'usage') AS del
,HAS_TABLE_PRIVILEGE(usrs.usename, fullobj, 'references') AND has_schema_privilege(usrs.usename, schemaname, 'usage') AS ref
FROM
(
SELECT schemaname, 't' AS obj_type, tablename AS objectname, schemaname + '.' + tablename AS fullobj FROM pg_tables
WHERE schemaname not in ('pg_internal')
UNION
SELECT schemaname, 'v' AS obj_type, viewname AS objectname, schemaname + '.' + viewname AS fullobj FROM pg_views
WHERE schemaname not in ('pg_internal')
) AS objs
,(SELECT * FROM pg_user) AS usrs
ORDER BY fullobj
)
WHERE (sel = true or ins = true or upd = true or del = true or ref = true)
and schemaname='<opt schema>'
and usename = '<opt username>';
