Write 10 SQL statements against the STUDENT schema you created for practice lab 1. Your statements should run error-free and should be valid. Submit two separate files: one plain text file (.txt or .sql file) with your statements only; and the other document (doc/docx/pdf) include both your statements and your query results (copy and paste text or screen shots). The instructor and TA should be able to run your plain text source file as script and generate the same output as shown in your result document.
