2. Write a script that creates and calls a stored procedure named invoice_balance. This stored procedure should use two variables to store (1) the count of all of the invoices in the Invoices table that have a balance due and (2) the sum of the balances due for all of those invoices. If that total balance due is greater than or equal to $30,000, the stored procedure should display a result set that displays the values of both variables. Otherwise, the procedure should display a result set that displays a message like this: Total balance due is less than $30,000.

The SERVICE_REQUEST table uses the CHAR data type for the DESCRIPTION and STATUS fields. Is there an alternate data type that could be used to store the values in these fields? Justify your reason for choosing an alternate data type or for leaving the data type as CHAR.
Write a script that creates and calls a stored procedure named spInsertDepartment. First, code a statement that creates a procedure that adds a new row to the Departments table. To do that, this procedure should have one parameter for the department name. Code at least two EXEC statements that test this procedure. (Note that this table does not allow duplicate department names.)
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.
Write a script that creates and calls a stored procedure named spUpdateInstructor that updates the AnnualSalary column in the Instructors table. This procedure should have one parameter for the instructor ID and another for the annual salary. If the value for the AnnualSalary column is a negative number, the stored procedure should raise an error that indicates that the value for this column must be a positive number. Code at least two EXEC statements that test this procedure.
9. Write a SELECT statement that uses aggregate window functions to calculate the total due for all vendors and the total due for each vendor. Return 3 Columns: The vendor id from the Invoices table. The balance due (invoice_total-payment_total-credit_total) for each invoice in the invoices table with a balance greater than 0. The total balance due for all vendors in the Invoices table. Modify the column that contains the balance due for each vendor so it contains a cumulative total by balance due.
"Create a stored procedure named spPriceRange that accepts two optional parameters. Theprocedure should return a result set consisting of Product Id, Product Name, ProductDescription, and List Price from the product and product description tables for each productwithin the price range, sorted with largest price first. The parameter @PriceMin and @PriceMaxare parameters used to specify the requested range of prices. If the minimum price is notprovided use the minimum non-zero price in the product table. If the maximum price is notprovided use the maximum price in the product table."
The following code would include: CREATE OR REPLACE TRIGGER TRG_LINE_PROD AFTER INSERT ON LINE FOR EACH ROW BEGIN UPDATE PRODUCT SET P_QOH = P_QOH - :NEW.LINE_UNITS WHERE PRODUCT.P_CODE = LINE.P_CODE; END; Group of answer choices A) Create a trigger named trg_line_prod that will automatically increase the product quantity on hand for each product sold after a new LINE row is added. B) Create a trigger named trg_line_prod that will automatically update the product quantity on hand for each product sold after the LINE table is modified. C) Create a trigger named trg_line_prod that will automatically reduce the product quantity on hand for each product sold after a new LINE row is added. D) This query will not work as it has syntax errors.
Produce a script file with 15 queries: At least two using join At least three using where clause At least three using order by At least two using single-row functions At least two using group by and group functions at least one nested query At least 4 queries from chapter 1 - 6 (exclude Create Table, Insert queries) ------- TABLE 1 create TABLE ProCoaches(pro_co_ID INTEGER PRIMARY KEY,pro_coachName Varchar(50) NOT NULL,pro_coachLocation Varchar(20)); INSERT INTO ProCoaches VALUES (1, 'John', 'Missoula'); INSERT INTO ProCoaches VALUES (2, 'Joe', 'Bozeman');INSERT INTO ProCoaches VALUES (3, 'Tara','Butte'); select * FROM ProCoaches;select LENGTH('Missoula') AS LengthOfLocation;select pro_coachName FROM ProCoaches where pro_coachLocation='Missoula'; select COUNT(pro_co_ID), pro_coachLocation FROM ProCoaches GROUP BY pro_coachLocation; TABLE 2 create TABLE ProCyclist(pro_cy_ID VARCHAR(10) PRIMARY KEY,pro_cyclist_Name VARCHAR(50) NOT NULL,pro_cyclist_Gender Varchar(20),pro_cyclist_DOB…
Create a trigger called Trig_Enroll_BI on the ENROLLMENT table that fires before an INSERT statement. The trigger must generate a proper error message if the student id or section id or both invalid. Test your code for all possible options. Make sure that all columns that have NOT NULL values (Use system date for all date fields, user id for all created and modified by fields). Display the inserted record from the ENROLLMENT table after a successful enrollment transaction.
If you are using Access 2016, do the following. Add a field to the Client table named AvailableCredit. Set the field to currency. Create a data macro associated with the After Update event for the Client table. When a user updates the Balance field, the macro should subtract the new balance from the credit limit and place that value in the AvailableCredit field. Create a data macro associated with the After Delete event for the OrderLine table. When a user deletes a record because it is complete or cancelled, the macro should look up the order number in the WorkOrders table and delete it there as well. Use the For Each Record in the WorkOrders table. Hint: You can use the OLD keyword in the Where Condition: [Old].[OrderNum] = [WorkOrders].[OrderNum]. Test the data macro by deleting a record from the OrderLine table and ensuring that the record also is deleted from the WorkOrders table.
Write a SELECT statement returns these columns from the orders table: The invoice_id column as Invoice_ID The invoice_date column as Invoice_Date The invoice_due_date column as Invoice_Due_Date The payment_date column in the format 'Mon/DD/YY' as Formatted_Payment_Date The invoice_due_date column in the format 'Weekday, Month Day of month with suffix, YYYY' (ex: 'Tuesday, April 23rd, 2019') as Long_Invoice_Due_Date The invoice_due_date plus 60 days as Expected_Payment_Date (Column must remain a date type) The number of days between the invoice_due_date and the payment_date as Time_To_Pay
please use store procedures to answer the following question Create a procedure to update Job Title for a given JOB_ID This procedure is called Update_Job_Title will have two INPUT parameters. p_job_id as VARCHAR2 as INPUT parameter and also p_new_job_title as VARCHAR2 as INPUT parameter. In BEGIN and END executable section Execute UPDATE command on JOBS table to change title of a JOB_ID Here is the command that you can use in BEGIN and END UPDATE JOBS SET job_title= p_new_job_title WHERE job_id= p_job_id; Test your code by executing procedure for below job_id. Currently in Jobs table you have Job_id = ‘MK_MAN’ and job_title=’ Marketing Manager’ Change title from Marketing Manager to Marketing Sr. Manager execute Update_Job_Title(‘MK_MAN’, ‘Marketing Sr. Manager’ )
