SQL Fiddle Exercise 3 - Numeric Filters

Write SQL code to only return purchases of 11 units. Rename the columns using aliases.

Remember to keep using /* comments */ to make the code clear!

Now amend your filter to only include purchases that sold 11 units and where the cost was 8 or more per unit.

The AND operator makes sure that only rows that meet both conditions are returned (in this case you should see only 2 rows).

Expand the expression so that either:

the above can be true or;
anything with a Price of 10 or more will be included.

Sort the results by Units Sold ascending.

This results in 31 rows being returned in the output: two from the original query and 29 that are returned by the price condition.

Check out the answer here.
