This join is
SELECT
s.id,
s.sector_abbr,
s.sector_desc,
l.id,
l.sector_id,
l.vendor_address_id
FROM sectors s
LEFT JOIN sector_vendor_address_link l
ON s.id = l.sector_id
is giving me this error
ERROR: ERROR: permission denied for relation sector_vendor_address_link
Using this id and password through razorSQL, I was able to do updates to these same tables, so I can't imagine it is a permissions problem. Perhaps I am wrong. Is my join just malformed?
Thanks!
EDIT:
It seems that I must manually set All privileges for each table. Is there any way using phpPgAdmin to globally set a users permission for the entire database?
Yes, you can set privs for newly created tables using ALTER DEFAULT PRIVILEGES.
For existing tables you must use GRANT to assign the desired rights. The ALL TABLES clause will be useful for that job.

I'm trying to figure out why a particular SQL Server database user that has db_datareader and db_datawriter membership, can't run a select statement that gets some check constraints on a particular table.
I run the select statement in my code, but it doesn't return any data. I thought maybe that in order to get constraint information, you might need different permissions. I've tried going out to look at some of the roles, and what they mean, but it's not clear what exactly the db_reader role can do.
string constraintCommand = #"SELECT tc.CONSTRAINT_NAME, CC.CHECK_CLAUSE
FROM[INFORMATION_SCHEMA].[CHECK_CONSTRAINTS as cc
INNER JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS as tc ON cc.CONSTRAINT_NAME = tc.CONSTRAINT_NAME AND cc.CONSTRAINT_SCHEMA = tc.TABLE_SCHEMA
WHERE tc.TABLE_NAME = 'VideoSources'";
This is in C#. I run the SQL statement in SSMS as me (db_owner), and the SQL statement returns the data I need. I'm wondering if it's a permission problem of some sort.
To run a stored procedure the role needs Execute permissions.
I believe that permission Grant or Deny overrides the role membership. You may have to specifically Grant Select permission in the table.
I had a schema in one oracle DB as ui_prod. I asked my DBA team guys to create exactly same schema like ui_prod but as read only and name it ui_prod_readonly. Usually I will use Oracle SQL developer to connect a DB and query directly with table name like below.
--Connect to ui_prod
select * from table
but why I requested to put owner name infront when query for readonly schema they created for me, as without putting it, I get error table not exist.
--Connect to ui_prod_readonly
select * from ui_prod.table
I have project files which hardcode the sql query with only table names and adding owner name in front will cause many changes and effort. Can anyone explain me on this? or provide me any document/link to read. Thanks
You should look into synonyms, apparently the user you are connecting to the database as is not the owner of the objects. So to view the object you have to prepend the names with the schema name (the owner of the object themselves).
http://www.techonthenet.com/oracle/synonyms.php
CREATE OR REPLACE SYNONYM ui_prod_readonly.synonym_name
FOR ui_prod.object_name
It seems to me that your dbas have not created another set of tables but just granted the existing tables to the user ui_prod_readonly.
When you log in to Oracle, the current schema is the name of the user you used to log in. So if you log in with ui_prod_readonly Oracle checks that schema for the table if you do not qualify it with the owner (=schema).
If you want to change the current schema so that you don't need to fully qualify the tables, you can do that with ALTER SESSION
alter session set current_schema = ui_prod;
Once you have done that, you don't need to fully qualify the table with the owner (=schema).
if you need a user to read the data only
its simple to create new user and grant it only select privilege
you can create user and grant select privilege using
CREATE USER [user] IDENTIFIED BY [your_password];
grant select on table to [user]
If I have two databases 'dbA' and 'dbB' using a normal account I know I can run a query such as
SELECT *
FROM dbA.dbo.TableA a
JOIN dbB.dbo.TableB b ON a.columnA=b.columnB
But I can not figure out how to grant permissions to a loginless account
USE dbA;
CREATE USER [test_user] WITHOUT LOGIN WITH DEFAULT_SCHEMA=[dbo]
GRANT SELECT ON DATABASE::dbA TO [test_user];
I receive an error when trying to give select permission to the loginless user 'test_user' on the other database.
GRANT SELECT ON DATABASE::dbB TO [test_user];
Is it possible to do a database join using loginless users? If so what should the grant statement look like for setting correct permissions?
A user without a login can only access other databases that have the guest user enabled. You might consider using a certificate-mapped user instead if you have a cross-database requirement. See http://www.sommarskog.se/grantperm.html for code.
Users exist at the database level. Only logins exist at the server level.
I believe you can create a view in dbA like so:
use dbA;
create view dbB_TableB as
select *
from dbB.dbo.TableB;
And you can then assign SELECT permissions for the user in dbA to the view.
I'm working with a legacy system that attempts to execute schema changes in SQL for specific users by first querying sysobjects as that user to determine if the object exists. If it does it creates an ALTER VIEW statement otherwise it creates a CREATE VIEW statement. In this case the view exists, but the query continues to fail to list the object.
For example:
setuser 'APPLICATION_DEV'
Select * from sysobjects o, sysusers u
where u.uid = o.uid
and u.name = N'APPLICATION_DEV'
The problem is that certain accounts in this database can run this query without error and it returns all of the objects owned by that user. Other accounts however get no records returned by this query. If I setuser to SA and run the query all of that users objects appear. The affected user is the owner of the schema and has create view permissions on the schema. I cannot find any differences in permissions between a working user and a non-working user account.
Is there a permission that I am missing that would restrict a user from querying their own objects in sysobjects?
Yes, I know sysobjects is obsolete, but I have no control over the actual code here and instead have to fix the database so their code will work as expected.
EDIT: Additional findings.
To complicate matters I can run this succesfully:
setuser 'APPLICATION_DEV'
Select * from sysusers
Where name = 'APPLICATION_DEV'
I can also execute this succesfully:
setuser 'APPLICATION_DEV'
Select * from sysobjects
Where uid = 308 --308 is the uid of the APPLICATION_DEV user
However, when I use a join either in the where clause or via INNER JOIN I then get no records. What would restrict my access to records purely based on the join? Index permissions?? I'm baffled.
For the particular user in user mapping check whether you have checked all the checkboxes apart from db_denydatareader and db_denydatawriter.
also check this
The SELECT permission was denied on the object 'sysobjects', database 'mssqlsystemresource', schema 'sys'

I'm trying to execute the following query through classic asp recordset -
SQL = "Select P_Name as P_Name, P_Description as P_Description
from L_PagePermission
inner join A_Permission on p_permissionID = pp_PermissionID
inner join A_Page on P_PageID = PP_PageID
where P_PageID = 85
order by p_Name"
Although I've ran into a problem with permissions. So the error that i am receiving is -
Microsoft OLE DB Provider for ODBC
Drivers error '80040e09'
[Microsoft][ODBC SQL Server
Driver][SQL Server]SELECT permission
denied on object 'A_Permission',
database 'HRWB_3_0', schema 'dbo'.
How would I go about executing this query without changing permission settings. How can I do this with a stored procedure? (Can someone provide an example too)
I can't change the database settings I have to deal with what I got. I've looked through a lot of the websites files and it seems to be mostly dependent on stored procedures.
You're not going to be able to get around that permissions error unless you grant select access on the L_PagePermission and A_Permission tables to the login that you are using to connect to the database, or unless you use a different login that already has select access to those tables.
Another approach would be to write a new stored procedure and grant EXECUTE access to that stored procedure. The SQL to grant permissions in either case is simple:
To grant SELECT access to a table:
GRANT SELECT ON [TableName] TO [loginName]
To grant EXECUTE access to a stored procedure:
GRANT EXECUTE ON [procedureName] TO [loginName]
One more approach that could work but has obvious security implications is to add the login you are using to the db_owner role for that database. That should work, but is NOT recommended unless you are comfortable with the security risks that presents.
If you don't have permission to select from the table, there won't be any way to work around the absence of permission other than connecting to the DBMS as a user who has permission to select from the table. That's the point of the permissions system - to prevent the unauthorized from doing what they are not allowed to do.
