Privileges for using ArcGIS with Teradata
Privileges determine what a user is authorized to do with the data and the database. Assign privileges based on the type of work the person does in the organization.
Users connecting to Teradata from ArcGIS require privileges on specific Teradata system tables and the user data they need to access. As a Teradata administrator, you create groups based on what users need to do in the database, grant privileges to the groups, and add the appropriate database users to each group.
Teradata grants the SELECT privilege on system tables to PUBLIC by default. If you revoke this privilege from PUBLIC, you must grant privileges to individual groups or users.
The following table lists three groups of users and the minimum privileges they require to query, edit, or create data from ArcGIS:
|
Type of user |
Required privileges |
Purpose |
|---|---|---|

Data viewer |
|
These privileges are required to read ST_Geometry metadata for spatial operations. |
|
|
This privilege allows data viewers to query data in specific tables. |
|
|
|
This privilege is required to preview features. |
|
|
Data editor Data editors require the same privileges as data viewers, as well as these additional privileges. |
|
Grant the editing operations you want editors to perform on specific tables. You can grant any combination of |
|
Data creator Data creators require the same privileges as data viewers, as well as these additional privileges. |
|
These privileges are required to update ST_Geometry metadata when creating or updating spatial data. Alternatively, you can grant |
|
|
These privileges are required to create tables and feature classes in the database. |
Note:
To edit data, publish editable web feature layers that reference the data in your Teradata database.
Additional, optional privileges you may want to grant data creators include the following:
CREATE VIEWandDROP VIEWGrant these privileges if you want to allow the data creator to create views on tables. This might be needed if the data creator owns feature classes that contain a spatial column that is not named shape. To use the data with ArcGIS, a view must be created on the feature class that aliases the spatial column to a column named shape.
CREATE TRIGGERandDROP TRIGGERThese privileges are required to create tessellation indexes, which use side tables that are updated via a trigger.
CREATE INDEXThis is required for data creators to create attribute indexes on their tables.
