User privileges for using ArcGIS with Teradata

As a Teradata administrator, you should 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.

The following table lists two groups of users who will connect from ArcGIS and the minimum privileges they require to query or create data.

Teradata grants SELECT privileges on system tables to PUBLIC by default. If you revoke those privileges, you must grant privileges to individual groups or users.

Type of user	Required privileges	Purpose
Data viewer	SELECT ON SYSSPATIAL.SPATIAL_REF_SYS SELECT ON SYSSPATIAL.GEOMETRY_COLUMNS SELECT ON DBC.TVM	Required to read ST_GEOMETRY metadata for spatial operations.
	SELECT ON <table1>,<table2>, <tablen>	Allows data viewers to query data in specific tables.
	UDTUSAGE ON SYSUDTLIB	Required to preview features.
Data creator Data creators require the same privileges as data viewers, plus these additional privileges.	INSERT ON SYSSPATIAL.SPATIAL_REF_SYS UPDATE ON SYSSPATIAL.GEOMETRY_COLUMNS EXECUTE FUNCTION ON SYSSPATIAL EXECUTE PROCEDURE ON SYSSPATIAL	Required to update ST_GEOMETRY metadata when creating or updating spatial data.
	CREATE TABLE DROP TABLE	Required to create tables and feature classes in the database.

Additional, optional privileges you may want to grant data creators are as follows:

• CREATE VIEW and DROP VIEW

  Grant 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 TRIGGER and DROP TRIGGER

  These privileges are required to create tessellation indexes, which use side tables that are updated via a trigger.

• CREATE INDEX

  This is required for data creators to create attribute indexes on their tables.
