mongodb get distinct records

Question

I am using mongoDB in which I have collection of following format.

{\"id\" : 1 , name : x  ttm : 23 , val : 5 }
{\"id\" : 1 , name : x  ttm : 34         


        

Answer 1

Specify Query with distinct. The following example returns the distinct values for the field sku, embedded in the item field, from the documents whose dept is equal to "A":

db.inventory.distinct( "item.sku", { dept: "A" } )
