database - What kind of index on dates for a emp duty table? -

-

i have query gets employee duties start date , end date against database. table like

  • emp
  • duty
  • startdate
  • enddate

should give indexing dates? kind etc? make things easier on db level (orm level me attribute set).there huge data depending on number of employees off course (expected) , better safe sorry?

please advice.

assuming have primary key on table, use non clustered indices on date fields if need search them oftenly - more important more data have in table.

adding 2 more indexes on table shouldn't hurt (though wouldn't index fields - asking trouble!).
