Assuming that you are connected to a database called Computers.mdb with the fields Computer, Hostname Room_Num, Num_CPUs, Speed, OS_Type, Memory, and HDD_Size, write the SQL Query String sqlStr such that all the fields in the table CompanyPCs will be displayed for the records that indicate a speed less than 2.0 and a memory value less than 4. The returned records should be sorted by Room_Num.
