I need some help with these queries. It would be too much to provide the tables and their fields, but any help is apprecited immensely!

Query8- Write an SQL query that shows the CustomerLastname, CustomerFirstName, SaleDate, EmployeeLastName and Employee Phone number for all sales made. Please name the query field columns as CustomerLastname, CustomerFirstName, EmployeeLastName and EmployeePhone. * You can use the AS keyword in the SELECT statement for this**

Query 9- Write an SQL query that shows customer ID and combines Lastname,FirstName in to one field separated by commas and another field that shows the total of all the sales the customer made with tax. (Note this refers to the Total field in the SALE table)

Query 10- Write an SQL query that shows the VendorID, CompanyName, and count of the number of items supplied by that vendor.
