I am using the sql developer and so far I have a schema class ADMIN with all the tables inside it and another schema which is called TEST. I granted select on all tables for the user TEST in the SCHEMA TEST:
GRANT select on ADMIN.TABLE1 to TEST
The privilege is granted successfully, but when I connect as user TEST, I cannot see the table in the SQL Developer.
What do I have to do so this table shows up for the user TEST?
Both tables are located on the same tablespace but I think that this is irrelevant.
The table still exists in the ADMIN schema. Granting read access to TEST does not make it appear in the TEST schema. While logged in as TEST you will be able to query the table and if you navigate to the ADMIN schema you will see it there. If you really want to see it in the TEST schema you can create a SYNONYM.
If you are talking about the explorer view of the schema in SQL Developer, there should be an item called "Other Users" (maybe "Other Schemas", can't recall for sure), under which you can view objects in other schemas that your schema has access to.

I have two schema "OWNER" and "USER".
I've created job in "OWNER" schema in PROD and we don't have access to login into this schema. Now I want to find a way to access these jobs in "USER" schema.
Below are the methods, I tried and did not work for me:
1)I created view in "OWNER" schema (create view test_view as select * from all_scheduler_jobs) and gave a grant "GRANT SELECT OWNER.test_view to USER". But still I did not find any records in USER schema.
2)Created a view as mentioned above and after that I created synonym in USER schema( create synonym USER.test_view for OWNER.test_view.
Please let me know if there is anything that I'm missing or is there any other way that I can implement.
The ALL_SCHEDULER_JOBS view only lets you see jobs to which you already have access - essentially just your own. To see properties or output from scheduler jobs belonging to other schemas, USER must have the SELECT ANY DICTIONARY privilege, which would allow access to the DBA_SCHEDULER_JOBS view. Check with your DBA to see if you are allowed to have that privilege (it opens up access to a lot of other things, too), or if they would prefer that you have a custom role that just grants access to the various DBA_SCHEDULER_% views. Note that these views would expose all jobs for all users, not just your OWNER schema; there isn't really a way to fine-tune that.
If USER needs to execute the job in another schema, then it will need the EXECUTE ANY JOB privilege, which would allow it to run any job in any schema. There's no way to make that more fine-grained at this time, either.
You can try below SQL.
SCHEMA: OWNER
commit;
SCHEMA: USER
select * from OWNER.test_view;
I was using node.js to work on snowflake datawarehouse as a destination for users. I wanted to check if a user has the required permission level on the schema to create a table and write into it before adding the user to the database otherwise it should give an error saying that the user does not have the appropriate permission level. How can I achieve that programatically?
Thanks,
one way you could do is check if the role has SEELCT privilege on the table by looking into the view TABLE_PRIVILEGES in information_schema schema.
select * from information_schema.TABLE_PRIVILEGES where table_name = 'SALES_RAW'
Due to how permissions can be inherited through the role hierarchy, this isn't easy to do. Permissions aren't assigned to users in Snowflake, they are assigned to roles. You could use the table_privileges in the information schema (as Himanshu said). You'll need to ask your admin for privileges to the information_schema schema in the databsae:
You could probably use some combination of these too:
show grants to user [username]
with
show grants on schema [schema name]
The easiest way would be to have your app / script / service assume the same role as the user and see if you can select from a table in the schema or try to create a temporary table in the schema. If you receive an error code, the user doesn't have permissions!
I have created a view in Database A that looks at tables in Database B that the users in Database A do not have access to (HR Data).
Is there a way I can grant anybody calling the view in Database A permissions to see the results, without giving access to the underlying tables?
Both databases are on the same instance, SQL Server 2019
You can just
GRANT SELECT ON OBJECT::[schema].[theView] TO User1,User2
in your Database A? This way you'd just give SELECT permissions to the view itself, and not the tables.
If you have a lot of cases like this, you can also consider creating a special schema for this and do:
GRANT select ON Schema :: [DBO] TO User1
instead.
I'm using the Oracle Database EX 11.2.0.2.0 and I hava a quite simple database created there.
Now the issue is i would like to have multiple users with different privileges set up. I have found that topic: How to create a user in Oracle 11g and grant permissions
but I cannot find anywhere the basic thing about users accounts:
what are the difference between creating system-leveled and particular database-leveled user?
I've logged in sqlplus as SYSTEM and executed the following commands:
CREATE USER TEST IDENTIFIED BY password;
GRANT CONNECT TO TEST;
and now the problem is that my databse is actually called let's say BASE with one table called PAYMENTS and to give any privileges to a newly created user I cannot execute:
GRANT SELECT ON PAYMENTS TO TEST;
but I have to type in:
GRANT SELECT ON BASE.PAYMENTS TO TEST;
so I suppose I missed something. Is it any way of connecting the created user to a particular database? So that the newly created user will be visible as a database user in Oracle APEX?
When referencing objects in other schemas, you must provide the schema name. An other user might have a table with the same name. Currently you are logged in with the system user, which is not advisable. When creating objects in the BASE schema (another name for user in de Oracle DB), why not give the user some extra rights (like granting privileges)?
The core of your problem is that you want to grant privileges to user A on object owned by B, logged in as user C. You have to be very specific in that case to Oracle what privileges are granted to whom ;)
Users and schemas are synonymous in Oracle - basically. A schema is the collection of objects owned by a user.
To get what you want, you would need to create users lacking the privs to create anything and only have the ability to select from the objects of others.
I use Schema in my database only for grouping tables, views, stored procedure, functions and other object by subject, and I dont realy know where schema must be used, and why schema tab is below security tab in SSMS.
EDIT :
Schemata are a way to logically group objects so that consistent permissions can be applied to all of them through the schema rather than individually. Consider:
create schema [foo] authorization [dbo]
grant select on schema::[foo] to [user1]
create table [foo].[table_1] (...)
create table [foo].[table_2] (...)
create table [foo].[table_3] (...)
By placing all of the tables in one schema, I was able to grant permission at the schema level and that notion of permission trickled down to all of the tables contained therein.
i think this placement is because of mapping between security of users (roles and users) and schemas. not data structure of schema, like tables and columns and so on.
if you go to security tab -> Users-> double click on on of the users. you find that you can edit mapping between that user and owned or role membership of SCHEMAs.
im hopeful to be useful for u.
