Performance / Query Tuning Question Regarding Missing Indices

$

0
Evening All,I am using some of the DMV's to identify missing indices on tables and their potential impact.It spits out 3 columns of interest:inequality columnsequality columnsincluded columnsThe latter I know what to do with, simply adding that as an included column..But it dawned on me, I don't really know how to react differently to the first two?I was going to create a nonclustered index covering both the fields in equality and inequality and then INCLUDE the including columns.But I am not sure if that's right? Are they split out into separate fields for a reason?These fields are sourced from dm_db_missing_index_detailsSo my ultimate question is how does one react between those 2-3 types of field mentioned above?CheersAlex
