 IN CONDITION FOR INDEX 

IN CONDITION FOR INDEX is a search strategy.

This search strategy can be used in the following cases:

·        The search condition contains an IN condition for the first column of an index that consists of multiple columns.

·        The search condition contains equality conditions for the first (k-1) columns of an index of this type and an IN condition for its k-th column.

The system uses the inversion lists to access the corresponding table rows directly.
