Need to Grant an access to only the view of XYZ schema, View internally call the Table from dbo Schema. need to restrict access to dbo table.
as i am only giving access to XYZ schema when i try to slect XYZ.VIEW. it gives and error:
Msg 229, Level 14, State 5, Line 2
The SELECT permission was denied on the object 'Table1', database 'servername', schema 'dbo'.
Query to Grant access to user
GRANT SELECT ON XYZ.VIEW TO user1
XYZ.VIEW Definition is below
SELECT NAME, Adress
FROM dbo.Table1
If you don't want the user to access the table and all of its contents and only access what you have in view, then create a Materialized view. This will isolate the user to what you give them and will remove the need to give them access to the table.

We have a azure based SQL Server instance that we are wanting to create a user who would only have SELECT access to two tables on a database that has many more tables. Is this possible? If so is there a guide I can follow to accomplish this?
Restrict user to certain tables in SQL
You can use the SQL GRANT statement to grant SQL SELECT, and other privileges on tables.
CREATE USER demouser
WITH PASSWORD = 'demopa#ssword1234';
GRANT SELECT ON dbo.student TO demouser
GRANT SELECT ON dbo.Airlines TO demouser
execute as user = 'demouser'
select * from student
select * from Airlines
REVERT;
Execution
Granted SELECT permission to user demouser on Airlines and student table.
demouser user has no access to mydata table
As you can see in picture I am connecting to my database as SYS with the SYSDBA below
The filtered tables shown in the picture 2 seems are system tables, right, as all tables names are ended with $?
I am wondering why SYS does not have permission to view the tables we created e.g filetable (as shown in the picture above). Is it because this ID does not have permission to select all tables? If yes, how can I allow the ID have permission to view all tables, including filetable?
Does this SYS account have FULL privileges in the database or not? I tried to use the below command to grant privileges to user but that didn't work, getting the error shown:
SQL> grant SELECT on filetable to user
grant SELECT on filetable to user
*
ERROR at line 1:
ORA-00942: table or view does not exist
What I need to do is create a user and grant select permission on all tables to this user.
What I need to do ?
Simple run
select owner, table_name from dba_tables where table_name= 'FILETABLE';
or fallback to query below if it is not a table, but a view or a materialized view
select owner, object_name, object_type from dba_objects where object_name= 'FILETABLE';
than take what you see in the column owner and query with (substitue [owner] with the owner you see) - if the query above return no rows the object does not exists.
select * from [owner].FILETABLE
I have created a table 'T' under user 'SYS'. Now I want to view the contents of the same table 'T' under another user 'JACH'. I have granted the select privileges' on table 'T' to user 'JACH'. But when I try to view the table under 'JACH', it says table doesn't exist. How do I view the table data under user 'JACH'?[Logged in as user 'SYS']
[Logged in as user 'JACH']
You need to schema qualify your select statement.
If a table is created under SCHEMA1 and you wish to query it while connected to SCHEMA2, assuming that SCHEMA2 has been granted SELECT/READ privileges properly, you should be able to query the table while connected to SCHEMA2 like this:
SELECT * FROM SCHEMA1.TABLE_NAME;
I have restricted select access at table level for 1 single table 'A'in sql server(2016).
But users are able to access views which are created top of that table 'A'.
when users run select statement on table 'A'(select * from table 'A')users are getting 'select permission is denied on object table 'A' ' message.
when users run select statement on view (select * from view 'A') users are able to access all data.
Users are able to create new views by writing select statement on table 'A'.
How can i restrict users to access table 'A' from views as well.
This is expected behavior due to ownership chaining. Permissions on tables referenced by the view are not checked as long as the view and tables have the same owner (AUTHORIZATION).
To break the ownership chain, you could either move the table to a different schema (owned by a different user than the view schema) or change to owner of the table. Examples below.
--move table to different schema
CREATE USER RestricedTablesOwner WITHOUT LOGIN;
GO
CREATE SCHEMA RestricedTables AUTHORIZATION RestricedTablesOwner;
GO
ALTER SCHEMA RestricedTables TRANSFER dbo.A;
GO
--change table to different owner, retaining same schema
ALTER AUTHORIZATION ON OBJECT::dbo.A TO RestricedTablesOwner;
I'm new to SQL and programming so I apologize if this isn't clearly worded.
I have the following code to create a user and role. I want user1 to be able to select and view table1.
When I run this code user1 isn't able to select table1 and I get the error that the table does not exist.
When prompted with the Database Entry screen I input user and password.
When prompted with the statement "Enter TNS_ADMIN entry or blank for Current Worksheet Database:" I don't input anything.
USER1 is able to connect, but not view the table. Under "other users" in the connection I see USER1 but none of the tables I've established are listed.
Thanks!
CREATE USER user1
IDENTIFIED BY user1
DEFAULT TABLESPACE users
TEMPORARY TABLESPACE temp
ACCOUNT UNLOCK;
CREATE ROLE ReadOnly;
GRANT SELECT ON table1 to ReadOnly;
--GRANT SELECT ON table2 to ReadOnly;
--GRANT SELECT ON table3 to ReadOnly;
GRANT CONNECT to user1;
GRANT ReadOnly to user1;
grant create session to user1;
connect user1
show user
select * from table1
Assuming that table1 is not owned by user1, you have three options
You can use the full name of the table in your query
SELECT * FROM <<schema name>>.table1
You can create a synonym for table1. A private synonym in the user1 schema would generally be preferred but a public synonym would also work. As user1
CREATE SYNONYM table1 FOR <<schema name>>.table1
SELECT * FROM table1;
Or you can change the default schema (for name resolution purposes, this has no impact on privileges)
ALTER SESSION SET current_schema=<<schema that owns table1>>
SELECT * FROM table1;
