Is anybody using index skip scan feature? What would be a situation in which the feature should be used? I have a SQL statement, part of ETL process that I have to tune.

Does anybody else have any type of practical experience with skip scans and index_ss hint? -- Mladen Gogala Oracle DBA Ext. 121 -- //www.freelists.org/webpage/oracle-l
