Accepted Answer

⚹ Based on the schema provided, it seems you are looking for help with writing SQL queries for a database that includes tables for 'takes', 'dept', 'course', 'advisor', 'time_slot', 'teaches', and 'student'. However, the specific queries you want to write are not clear from your question. To assist you better, I will provide you with a general guide on how to write SQL queries for such a schema. ⚹ ∻General Guide for Writing SQL Queries∻ ‖ ▪ ⋮ Selecting Data: Use the SELECT statement to specify the columns you want to retrieve, followed by the FROM clause to specify the table. ‖ ‖ ▪ ⋮ Filtering Data: Use the WHERE clause to filter the data based on specific conditions. ‖ ‖ ▪ ⋮ Joining Tables: Use JOIN clauses (INNER JOIN, LEFT JOIN, etc.) to combine rows from two or more tables based on a related column. ‖ ‖ ▪ ⋮ Ordering Results: Use the ORDER BY clause to sort the result set in ascending or descending order. ‖ ‖ ▪ ⋮ Grouping Data: Use the GROUP BY clause to group rows that have the same values in specified columns into summary rows. ‖ ‖ ▪ ⋮ Aggregating Data: Use aggregate functions (SUM, AVG, COUNT, etc.) to perform a calculation on a set of values and return a single value. ‖ ⚹ If you can provide specific details about the queries you need to write, I can give you more targeted assistance. For example, if you need to find all students who are taking a specific course, the query would look something like this: ⚹ ```sql SELECT student.ID, student.name FROM student JOIN takes ON student.ID = takes.ID WHERE takes.course_id = 'CS101'; ``` ⚹ Please provide more details for a precise answer. ⚹
