Referenced Columns

Many of the Data Dictionary view columns have referenced table columns. That is, the value in the view column corresponds to a value in the selected column referenced in the table. It would be meaningful to join the view and the referenced table based on the selected column and the referenced column.

Referenced columns for this view are:

View Column Referenced Column
IndexNumber DBC.Indexes.IndexNumber
