Privilege applies to all external stored procedures in the specified space.
Privilege applies to the journal table in the specified database. DBC can grant the privilege to any other user or role defined for your system. This privilege is not granted automatically when a user or database is created. Privilege is a total system privilege and is not granted to or revoked from specific tables or databases.
Privilege applies to all tables or views in the specified database. For a grantee to use the granted privileges on a view, the immediate owner of a view must have appropriate privileges on the tables and views referenced by the view.
Privilege applies only to the specified table, view, or columns. This privilege is automatically granted to the creator and owner of the GLOP set. Privilege applies to all UDFs or macros in the specified database. For the grantee to use the privilege on a UDF or macro, the immediate owner of the macro or UDF must have appropriate privileges on the objects referenced by the macro or UDF.
For the grantee to use the privilege on a UDF or macro, the immediate owner of the macro must have appropriate privileges on the objects referenced by the macro. Privilege applies to all UDFs or stored procedures in the specified space.
For the grantee to use the privilege on a procedure, the immediate owner of the stored procedure must have the appropriate privileges on the objects referenced by the stored procedure.
For more information, see Temporal Table Support. Privilege applies at the table level. If a user has the override privilege, the request must specify the values to be assigned to the constraint columns of the target rows. Note: It is not necessary for a database to have a table that contains one or more row-level security constraints.
Privilege does not allow the grantee the ability to perform any operations on the granted database object other than to make a HELP or SHOW request against it. Privilege to collect statistics on a table, hash index, join index, or database. GRANT always applies to the base global temporary table and never to a materialized instance. Just as with permanent tables, a user must have the appropriate privileges before submitting a GRANT request. Teradata Database also verifies that the appropriate privileges exist on the target objects for any user who attempts to access a view, or perform a macro or stored procedure.
This ensures that a change to a target object does not cause a violation of privileges when the view, macro, or stored procedure referencing that object is invoked. The SHOW privilege enables you to have access to database object definitions and create text without having access to the data contained by the objects on which the privilege is granted.
SHOW is an explicit privilege. Teradata Database does not grant the creator of an object this privilege automatically on the created user, database, or database object; SHOW must be granted explicitly. Teradata Database does not grant any of the GLOP privileges automatically when a database or user is created. The following table describes the privileges of different types of users or grantors with respect to stored procedure-specific privileges:. Except for user DBC , owners do not implicitly have this privilege.
If the immediate owner of the procedure is different from its creator, the owner does not receive this privilege automatically. Do not grant this privilege to any user other than a DBA. For more information on the privileges mentioned in this section, see:.
The following rules apply to privileges specific to stored procedures:. If no macro of that name exists, an error or failure is returned. Even then, you should restrict this privilege to only your most trusted programmers.
You must also ensure that the external procedure is thoroughly tested to verify that it does not compromise the system in any way. External stored procedures execute as part of the system when running in unprotected mode, while protected mode external stored procedures run in a separate process as an ordinary user named tdatuser.
This is also true for all newly created methods and external stored procedures. UDFs do not run in modes. The exception is constraint functions. This privilege does not need to be granted on constraint functions to users that need to query tables that are protected by row-level security. They cannot create or delete UDTs, create, alter, or delete methods, or alter the behavior of a UDT with respect to ordering, casting, or transform functionality.
With regard to nested structured UDTs, be aware that privileges are not automatically inherited from their parents. However, that privilege does not grant you the ability to use observer or mutator methods on any of the structured attributes in the lower layers of that UDT, nor can you invoke any of the methods defined for those lower layered attributes. A user must either be granted this privilege explicitly or acquire it through a role.
AccessRights table. A user must either be granted this privilege or acquire it through a role. Its functionally includes both of the following privileges:. The Teradata Row Level Security feature provides a number of privileges that administrators can use to establish and maintain row-level security for the system.
Some of the privileges are system-level privileges and some are object-level privileges. Initially, only user DBC has row-level security privileges. Any other user must be explicitly granted row-level security privileges to be able to:.
Note: Although row-level security credentials are not privileges, they work like required privileges do in other types of access control. When you assign security credentials to users or profiles, you are essentially determining whether the users are able to access table rows that are protected by row-level security.
The security credential assigned to the users must match the security constraint values assigned to the row or rows they are attempting to access. The exact type or types of access you permit is determined by the row-level security policy defined in the constraint function.
Administrators can grant system-level privileges to users or profiles for the purpose of establishing and maintaining row-level security. See the section on the DBC. AccessRights table in Data Dictionary for a list of the two character abbreviations for these privileges. Administrators can grant it to individual users or to profiles. These statements can be used on users or profiles that do not have security credentials assigned to them.
Administrators can grant it to individual users or to roles. Administrators can grant these privileges for the purpose of temporarily enabling users to bypass override the row-level security policy defined on database objects. Because these privileges enable users to override row-level security policy restrictions, they are referred to as override privileges.
These object-level privileges enable users to execute DML requests on tables that have row-level security restrictions that prohibit delete, insert, select, and update operations. Administrators can grant these privileges to temporarily enable users to execute DML requests to perform the prohibited delete, insert, select, and update operations.
When granted on a constraint column , it enables users to bypass validation of the DELETE security policy for a specific constraint function. Note: Even if this privilege is granted on the target table, a user is not able to delete all rows of the table. Teradata Database ensures that the value assigned to a constraint column is one specified by the name:code pairs of the constraint.
When granted on a single constraint column , it enables a user to bypass the security policy in the SELECT constraint function associated with that constraint column. This application is used to permit a user to retrieve a single row. When granted on all constraint columns , it enables a user to retrieve all rows of the table, because the user is able to bypass the security policy in the SELECT constraint functions associated with all constraint columns of the table.
If a constraint function does not exist for a type of DML request, the request can only be executed by a user who has the override privilege for that type of request. The rules and restrictions for granting the DML restriction override privilege are:. Administrators can grant these privileges on databases or tables. Unlike the DML restriction override privileges, these privileges do not bypass the row-level security policies defined in constraint functions UDFs.
Note: These privileges are not sufficient to archive or restore tables that have row-level security constraints or databases that have tables with row-level security constraints. Roles define privileges on database objects. A database administrator can create different roles for different job functions and responsibilities, grant specific privileges on database objects to the roles, and then grant membership to the roles to users.
Users who are members of a role can access all the objects for which the role has privileges. Its showing syntax error.. I'll try again — Avijit Banerjee. Add a comment. Active Oldest Votes.
