Error : Conversion failed converting date and/or time

I have a table with InsertedDate column which data type is 'Date'. 

This column has today's date stored as  '2017-07-12'. 

 

Now I am trying to count the from this table based on today's date,

 

my query is :

 

SELECT Count(ProductSold) from ProductSalesDetail WHERE(DATEPART(yy, 'InsertedDate') = 2017 AND DATEPART(mm, 'InsertedDate') = 07 AND DATEPART(dd, 'InsertedDate') = 12) 

 

It throws error : Conversion failed when converting date and/or time from character string.

 

how do i perform this operation ?
