Step by step
Solved in 2 steps
- The InstantRide Driver Relationship team wants to learn how many travels each driver has done in the month of October. You need to send them the DRIVER_ID, and two calculated columns: DAY and RIDES. The DAY column is calculated using the DAY() function with the TRAVEL_START_TIME as the argument. The RIDES column is calculated by using the COUNT() function to determine the number of rides given for each day. Filter the results with the MONTH function.The InstantRide User Satisfaction team received a phone call from a user who might have left her wallet in the car. She indicated that the license plate of the car was starting with BB-883 but unfortunately, she could not remember the full license plate number. The team wants to get all travel information for the cars with the license plate starting with BB-883. You need to return all travel data from the TRAVELS table for the CAR_ID which has a plate number compared with SUBSTR and UPPER functions.StayWell’s maintenance team wants to recheck the apartments that had plumbing service requests beforehand. You will need to return all the property IDs and the addresses of the properties that had plumbing service request (CATEGORY_NUMBER 1). Task Return a list of all the property IDs and the addresses of the properties that had plumbing service requests.
- Write a stored procedure called sp_apply_discount() that will apply percent discount to books in a subject. The stored procedure takes in 2 parameters, percentDiscount (DECIMAL(8,2)) and subject (VARCHAR(120)). Using these parameters, the stored procedure computes the discount for the book cost and stores it in the FINAL_PRICE field. For example, the following stored procedure call: call sp_apply_discount(0.15, 'Database');would compute 15% percent discount from the book cost in the Database subject category and store it in the FINAL_PRICE column as depicted in this image:MySQL Create the DISPLAY_PROPERTY_OWNER procedure which obtains the office location number, address, owner number, owner first name, and owner last name for the property whose property ID is currently stored in I_PROPERTY_ID (provided as a parameter). Place these values in the variables I_LOCATION_NUM, I_ADDRESS, I_OWNER_NUM, I_FIRST_NAME, and I_LAST_NAME, respectively. Output the contents of I_LOCATION_NUM, I_ADDRESS, I_OWNER_NUM, I_FIRST_NAME, and I_LAST_NAME5: Create the GET_CREDIT_LIMIT procedure to obtain the full name and credit limit of the customer whose ID currently is stored in I_CUST_ID. Place these values in the variables I_CUSTOMER_NAME and I_CREDIT_LIMIT, respectively. When the procedure is called it should output the contents of I_CUSTOMER_NAME and I_CREDIT_LIMIT. HERE'S MY QUERY -- create a procedure named GET_CREDIT_LIMIT -- use I_CUST_ID as a input parameter -- use I_CUSTOMER_NAME, I_CREDIT_LIMIT as output parameters -- select columns CONCAT(FIRST_NAME, ' ', LAST_NAME), CREDIT_LIMIT and store the values in I_CUSTOMER_NAME, I_CREDIT_LIMIT -- using where clause to match the CUST_ID to currently stored in I_CUST_ID(provided as a parameter) DELIMITER // CREATE PROCEDURE GET_CREDIT_LIMIT ( IN I_CUST_ID int, OUT I_CUSTOMER_NAME varchar(75), OUT I_CREDIT_LIMIT decimal(10,2) ) BEGIN SELECT CONCAT(FIRST_NAME, ' ', LAST_NAME), CREDIT_LIMIT INTO I_CUSTOMER_NAME, I_CREDIT_LIMIT FROM CUSTOMER WHERE CUST_ID = I_CUST_ID; END // DELIMITER…
- Write a script that creates and calls a stored procedure named spInsertInstructor that inserts a row into the Instructors table. This stored procedure should accept one parameter for each of these columns: LastName, FirstName, Status, DepartmentChairman, AnnualSalary, and DepartmentID. This stored procedure should set the DateAdded column to the current date. If the value for the AnnualSalary column is a negative number, the stored procedure should raise an error that indicates that this column doesn’t accept negative numbers. Code at least two EXEC statements that test this procedure.Report R commands that recode the remaining variables (heat, sewer, construction)in Houses_small, then remove the original (integer-valued) variables. You should endup with this:MySQL Create the DISPLAY_OWNER procedure which obtains the first name and last name of the owner whose number currently is stored in I_OWNER_NUM (provided as a parameter). Place these values in the variables I_FIRST_NAME and I_LAST_NAME. Output the contents of I_OWNER_NUM, I_FIRST_NAME, and I_LAST_NAME.
- The Driver Relationship team realized that maintaining driver IDs is difficult and requested an automatic way of incrementing the value when a new driver is added. You need to make the changes on the table to automatically increment the Driver ID. After the change, you need to insert the following driver: First Name: Nursin Last Name: Yilmaz Driving License ID: 4141447 Start Date: 2019-12-28 Driving License Checked: True Rating: 4.0Create the DISPLAY_OWNER procedure which obtains the first name and last name of the owner whose number currently is stored in I_OWNER_NUM (provided as a parameter). Place these values in the variables I_FIRST_NAME and I_LAST_NAME. Output the contents of I_OWNER_NUM, I_FIRST_NAME, and I_LAST_NAME. IN MYSQLUSING MYSQL Create the DISPLAY_OWNER procedure which obtains the first name and last name of the owner whose number currently is stored in I_OWNER_NUM (provided as a parameter). Place these values in the variables I_FIRST_NAME and I_LAST_NAME. Output the contents of I_OWNER_NUM, I_FIRST_NAME, and I_LAST_NAME. HERE is what i have so far, but getting these errors DELIMITER // CREATE PROCEDURE DISPLAY_OWNER (INOUT I_OWNER_NUM varchar(10), OUT I_FIRST_NAME varchar(10),OUT I_LAST_NAME varchar (10)) BEGIN SELECT OWNER_NUM,FIRST_NAME,LASTNAME INTO I_OWNER_NUM,I_FIRST_NAME,I_LAST_NAME FROM OWNER WHERE OWNER_NUM = I_OWNER_NUM; END// DELIMITER; also i need to display these outputs CALL DISPLAY_OWNER('AK102') Expected Results I_OWNER_NUM I_FIRST_NAME I_LAST_NAME AK102 Ceyda Aksoy
