Computer Science Write a script that creates four login IDs based on the contents of a new table named NewLogins: CREATE TABLE NewLogins (LoginName varchar(128)); INSERT NewLogins VALUES ('BBrown'), ('CChaplin'), ('DDyer'), ('EEbbers'); Use dynamic SQL and a cursor to perform four actions for each row in this table: (1) create a login with a temporary password that's based on the first four letters of the login name followed by “99999”; (2) set the default database to the AP database; (3) create a user for the login with the same name as the login; and (4) assign the user to the PaymentEntry role you created in exercise 1..
MYASQL 7. Create Avgoffreight() stored procedure to retrieve the average of freight from Orders table. Then , show the result.8. Write a database trigger TO insert the UnitPrice field.IF UnitPrice is less than 10 then make it equal to 10.(BEFORE INSERT). Test the trigger and show its result.procedure and trigger9. Select the first 10 characters of each customer's address. (Hint: You can use one of the built-in functions that are explained in functions file). (bonus, if you want to get higher mark, you can answer it, if not ,you can upload the solution file without it )
9. Write a trigger that prohibits duplicate values except for nulls in the NoDupName column of the following table: CREATE TABLE TestUniqueNulls (RowID NoDupName varchar(20) int IDENTITY NOT NULL, NULL); (Note that you can’t do this by using a unique constraint because the constraint wouldn’t allow duplicate null values.) If an INSERT or UPDATE statement creates a duplicate value, roll back the statement and return an error message. Write a series of INSERT statements that tests that duplicate null values are allowed but duplicates of other values are not.

Relation Students has schema: CREATE TABLE Students ( Banner ID CHAR(9); stuName VARCHAR(40) NOT NULL, scholarship INT, PRIMARY KEY(BannerID) ); The relation Students is currently empty. Develop a test that determines whether an insertion into Students is currently legal. Then apply your test to determine which of the following INSERT statements is allowable. A. INSERT INTO Students (scholarship) VALUES(0); B. INSERT INTO Students VALUES('950111222' NOT NULL, 10000); C. INSERT INTO Students (BannerID, Scholarship) VALUES)'950111444', 10000); D. INSERT INTO Students VALUES('950111222', 'John Greens', 10000);
