---++SQL Lab 2
This lab uses the enrollment data.<br><br>

Only turn in the sql statements (not the results of the query). You may test your queries out online. (But remember, just because you get the right data back, that does not mean your query is correct!). Turn in an electronic copy or your .sql file. BE sure to include your name and label each question (using commnets).<br><br>
Unless otherwise specified, you may use your "id number" in the query.<br><br>
