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 Operators and User-Defined Functions, 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 Examples: Using QryLogFeatureListV.

To enable feature use logging, see BEGIN QUERY LOGGING in Teradata Vantage™ SQL Data Definition Language Syntax and Examples, B035-1444.
