Make advantage of the organization of their data using a SQL query to find out who hasn't taken any of their courses. Don't do any set operations or subqueries (use an outer join).
Step by step
Solved in 2 steps
- Using the university schema, write an SQL query to find the names and IDs of those instructors who teach every course taught in his or her department (i.e., every course that appears in the course relation with the instructor’s department name). Order result by name.Write a SQL query. List names of all employees who have sold to customer Rachel Patterson (Note: You can only use the information given in the question, i.e. you cannot first look up Rachel Patterson’s Customer ID and use that ID in your query).Write a SQL query using their schema to find out who hasn't taken a course at the university. There should be no subqueries or set actions (use an outer join).
- Write SQL codes according to the requirements given. Tables are imaginary, column names can be made up. List the item ID, description, and category for each pair of items that are in the same category. (For example, one such pair would be item FS42 and item PF19, because the category for both items is FSH.) List the invoice number and invoice date for each invoice created for the customer James Gonzalez. Use a subquery to find the sales rep ID, first name, and last name of each sales rep who represents at least one customer with a credit limit of $500. List each sales rep only once in the results.Using the university schema, write an SQL query to find the names and IDs ofthose instructors who teach every course taught in his or her department (i.e.,every course that appears in the course relation with the instructor’s department name). Order result by nameUsing the relations in the appendix, write the following queries in SQL:i. Display a list of all instructors, showing each instructor’s ID and the number of sections taught. Your query should use an outer join, and should not use sub-queries.ii. Write the same query as in part a, but using a scalar subquery and not using outer join.iii. Display the list of all course sections offered in spring 2018, along with the ID and name of each instructor teaching the section. If a section has more than one instructor, that section should appear as many times in the result as it has instructors. If a section does not have any instructor, it should still appear in the result with the instructor name set to “—”.iv. Display the list of all departments, with the total number of instructors in each department, without using sub-queries. Make sure to show departments that have no instructors, and list those departments with an instructor count of zero.
- please use sql to answer the following question (an erd has been add) Group By / Subquery Determine how many orders have been placed by each customer. Do not include in the results any customer who hasn’t recently placed an order with JustLee Books.Use SQL and TAL Distributors database to complete the following questions:List the customer number and name for all customers located in the city of Grove. Your query should ignore case. For example, a customer with the city Grove should be included as should customers whose city is GROVE, grove, GrOvE, and so on.Answer the query using SQL. As an employee, “Alice Kay" works for a department. For this department, list department name and department manager's first name and last name. Note: This question is not relevant to "supervisor".
- Write the SQL queries for the following questions and show results. List all the section numbers of course 'Syst Analysis'. List, in alphabetical order, the names of those students who have been enrolled in “ISM” class.Using the sample "Solmaris Condo" "database" (just a bunch of tables with a theme) I had you create before this test, write a SQL statement to do the following: List the condo ID, square footage, owner number, service ID, number of estimated hours, and number of spent hours for each service request on which the category number is 4.Write the following queries in SQL, using the university schema. Find the ID and name of each student who has taken at least one Comp. Sci. course; make sure there are no duplicate names in the result.
