I have the same question but well a not-so-elegant solution would be to define a view within your DBMS e.g. CREATE VIEW view_name AS (SELECT ...your_query) and then apply a SELECT COUNT(*) FROM view_name
You can sort the results of a query by using the order by clause. Ex: Select * from tbl_employee order by emp_num The above query would sort the results by the employee number and display them. The default sort is ascending order. Ex: Select * from tbl_employee order by emp_num desc The above query would sort the results by descending order of employee number and display them.
You would use a JOIN query for this.

There are occasions when you would need to bring in the same table twice, but usually you don't. If you have it in twice it will list records multiple times. Go to the design view of the query and if you see the table there more than once, delete the extra copies of it, so that there is only one. Then design your query and it should be ok.
a parameter query is a query that prompts the user to enter specific criteria every time the query is run. When building the query, you would enter the prompt in the criteria line under the field you want the information to be filtered from. For example, if you wanted to look at items that sold on a specific date each time you ran the query, your criteria line would look like this: [enter date of sale] So when you ran the query, before your results even appeared, a parameter box would pop up telling you "enter date of sale", the user would enter the date and then the filtered criteria of the query results will show.
