Write a query to produce the total number of hours round to 1 digit and charges round to  2 digits for each of the projects represented in the ASSIGNMENT table, sorted by project number.  In the SQL Query do the following  Select clause: Proj_Num, sum of Assign_hours rounded to 1 place, sum of  Assign_charge rounded to 2 places (You will be using SUM and ROUND to achieve the  intended result)  From: ASSIGNMENT  Where clause: not needed because we are not restricting anything here Group by clause: project number column.   Since we are using sum to calculate total number of hours and total charges we have to use group by clause for the columns that are not involved in the calculation which is project number column.

Question

Write a query to produce the total number of hours round to 1 digit and charges round to  2 digits for each of the projects represented in the ASSIGNMENT table, sorted by project number. 

In the SQL Query do the following 

Select clause: Proj_Num, sum of Assign_hours rounded to 1 place, sum of  Assign_charge rounded to 2 places (You will be using SUM and ROUND to achieve the  intended result) 

From: ASSIGNMENT 

Where clause: not needed because we are not restricting anything here Group by clause: project number column.  

Since we are using sum to calculate total number of hours and total charges we have to use group by clause for the columns that are not involved in the calculation which is project number column.
