The following provides information for accessing the resource usage views.

Views are the recommended method to access the resource usage table data.

To see the view definitions, execute SHOW VIEW viewname, where viewname is the name of the view whose most recent SQL create text is to be reported. For details on using the SHOW VIEW statement, see Teradata Vantage™ - SQL Data Definition Language Detailed Topics , B035-1184 .

The following views report the table column, GroupId. A homogeneous system requires no changes to use this macro because all the nodes will be assigned to group A. For a coexisting system, however, the values need to be set up when the system is installed or reconfigured so that each type of node is assigned to a specific group ID.

Since each of the views include all the columns for the represented table, the views will be changed whenever the base table columns are changed.

Do not change or delete columns in these views. If the columns are modified, the resource usage macros that use these views may not work properly. You can, however, safely add columns.
