SQL/MX 3.2 Management Manual (H06.25+, J06.14+)

Displaying Information About Privileges
Topics in this subsection:
• “Displaying all Privileges for a Table” (page 144)
• “Displaying all Privileges for a View” (page 145)
• “Displaying all Privileges for a Column” (page 146)
The TBL_PRIVILEGES table, located in the schema
DEFINITION_SCHEMA_VERSION_version-number of each catalog, describes the privileges
for all tables and views in that catalog. The COL_PRIVILEGES table, located in the schema
DEFINITION_SCHEMA_VERSION_version-number of each catalog, describes the privileges
for all columns in that catalog. For more information about all metadata tables, see Figure 3
(page 108) in this manual or the SQL/MX Reference Manual.
All queries for information about privileges must access information from the CATSYS, SCHEMATA,
and OBJECTS tables, and from other appropriate tables, such as the TBL_PRIVILEGES table.
The SHOWDDL command does not display information about privileges.
Displaying all Privileges for a Table
This example displays all privileges for the table SAMDBCAT.SALES.ORDERS:
>>set schema samdbcat.definition_schema_version_<schema version>;
--- SQL operation complete.
>> select grantor as grantor_id,
case (grantor_type)
when 'S' then 'System'
when 'U' then 'User'
else 'Unknown'
end as grantor_t,
grantee as grantee_id,
case (grantee_type)
when 'P' then 'Public'
when 'U' then 'User'
else 'Unknown'
end as grantee_t,
case (privilege_type)
when 'S' then 'Select'
when 'I' then 'Insert'
when 'D' then 'Delete'
when 'U' then 'Update'
when 'R' then 'Refer'
else 'Unknown'
end as prvtype,
is_grantable as grantable
from tbl_privileges t, objects o
where t.table_uid = o.object_uid
and o.object_name = 'ORDERS'
and o.object_type = 'BT'
and o.schema_uid =
(select schema_uid
from nonstop_sqlmx_<sys name>.system_schema.schemata
where
schema_name = 'SALES' and
cat_uid =
(select cat_uid
from nonstop_sqlmx_<sys name>.system_schema.catsys
where cat_name = 'SAMDBCAT'
)
