Abstract
In an embodiment, a threshold value is calculated for a current entry in a first column of an index. If the current entry has been read a number of times by execution of an execution plan that is more than the threshold value and the current entry points to at least one row in a table and not all of the at least one row have been selected by the execution plan for inclusion in a result set as satisfying a query that the execution plan implements, then a new entry is added to the index.
