MySQL Will you write the code in MySQL Alter table employee so that column zipCode is a foreign key to table cityState, column zipCode Alter table customer so that column zipCode is a foreign key to table cityState, column zipCode zipCode is the foreign key. Cannot add or update a child row: a foreign key constraint fails (`dealership`.`#sql-163c_33`, CONSTRAINT `customer_ibfk_1` FOREIGN KEY (`zipCode`) REFERENCES `citystate` (`zipCode`)) shows on my screen after I alter table employee.

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..
CREATE TABLE MOVIE( mov_id int NOT NULL, mov_title varchar(255) NOT NULL, mov_releaseDate date, gen_id int NOT NULL, PRIMARY KEY (mov_id), FOREIGN KEY (gen_id) REFERENCES GENRE(gen_id) ); CREATE TABLE GENRE( gen_id int NOT NULL, PRIMARY KEY (gen_id), gen_name varchar(255) NOT NULL ); Search movies by year. Using the tables above, create a stored procedure, called getMovieByYear, that, given a year, returns all the movies which were released in that year. It displays the movie title, movie’s genre name, and release year.please use MySQL Workbench with screenshots of it for the explanation.

This does not work: CREATE OR REPLACE TRIGGER trg_char_hours AFTER INSERT ON CHARTER FOR EACH ROW BEGIN UPDATE AIRCRAFT SET AC_TTAF = AC_TTAF + NEW.CHAR_HOURS_FLOWN, AC_TTEL = AC_TTEL + NEW.CHAR_HOURS_FLOWN, AC_TTER = AC_TTER + NEW.CHAR_HOURS_FLOWN WHERE AIRCRAFT.AC_NUMBER = NEW.AC_NUMBER; END; I get the following error: ERROR 1064 (42000) at line 1: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'TRIGGER trg_char_hours AFTER INSERT ON CHARTER FOR EACH ROW BEGIN UPDATE AIRCRAF' at line 1 Here is the original question: Create a trigger named trg_char_hours that automatically updates the AIRCRAFT table when a new CHARTER row is added. Use the CHARTER table’s CHAR_HOURS_FLOWN to update the AIRCRAFT table’s AC_TTAF, AC_TTEL, and AC_TTER values. (Hint: use temp values, as the INSERT event does not accept the OLD keyword.)
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.
