Hi All,

As per the attache files or below specified table DDL, DML and SQL, I need to get below details:

Get Order_ID, Order_Date, Salesman_ID for different Salesmen :

1. Who sold maximum Copy for a day

2. Who sold maximum amount of book for a day

3. Who got maximum order for a day

As per below SQL, I am able to fetch the result only in one record that is correct. But I need to get the data for every single date i.e. for all distinct date only, i.e. Date should not repeat in the row, which satisfy above three condition. The result could be for different Salesmen or same Salesman depending on the data in the table.

So, I need to get data for every distinct date in the table. Please help how to get it.

One option I see to put "Order_ID" column in Max() function to avoid Group By issue.

Kindly suggest, If possible please correct the above SQL and share.

Thanks In Advance.

With Best Regards.

Vishal
