The QryLogFeatureListV view lists all the feature names that can be tracked when feature usage is enabled.

This view is populated whether or not the WITH FEATUREINFO option for BEGIN/REPLACE QUERY LOGGING is enabled. QryLogFeatureListV provides a view into the table function SYSLIB.FeatureNames_TBF. For more information about the table function, see Teradata® Vantage SQL Support for Database Administration, B035-1210.

Use this view to obtain the following information:
  • How many times a feature was used in a given period of time; for example, how many times a feature was used in a day or in the last week, and so on
  • List the most used feature in a release
  • List what percentage of the requests used a certain feature
  • List the last time a particular feature was used
The feature list is subject to change each Teradata release. To see the current list of features that are tracked, see Example: Using QryLogFeatureListV to List Features.

To enable feature use logging, see BEGIN QUERY LOGGING in Teradata® Vantage SQL Data Definition Language Syntax and Examples, B035-1144.
