I am having some trouble with this for an assignment in Database. I am trying to create some queries for this homework: Assignment 5: Data Definition language and Transaction in MySQL This is what I am currently working on: On June 3, 2019, customer ‘10010’ makes a payment of $100 in cash. The payment ID is 3428. The query as it is as of this moment: SELECT PAYMENTINSERT INTO PAYMENT (PMT_ID,PMT_DATE,CUS_CODE,PMT_AMT,PMT_TYPE,PMT_DETAILS)VALUES(3428,6-3-2019,10010,100.00,cash,account),UPDATE CUSTOMERSET CUS_BALANCE = CUS_BALANCE + 100WHERE CUS_CODE=10010,COMMIT 2. On May 11, 2019, customer ‘10012’ makes a credit purchase of one unit of product ‘11QER/31’ with a unit price of $110.00; the invoice total is $118.80. The invoice number is 10983, and this invoice has only one product line. [note: no payment has been made here] The Query as of now: BEGIN TRANSACTION; INSERT INTO VOICE VALUES (10983, 10012, ’5-11-2019’), INSERT INTO LINE VALUES (10983, 1, ‘11QER/31’, 1, 110.00), UPDATE…

The table R(x,y) currently has the following tuples (note there are duplicates): (1,2), (1,2), (2,3), (3,4), (3,4), (4,1), (4,1), (4,1), (4,2). Compute the result of the query: SELECT R1.x, R2.y, COUNT(*) FROM R R1, R R2 WHERE R1.y = R2.x GROUP BY R1.x, R2.y; Which of the following tuples is in the result? O a. (3, 4, 6) O b. (3, 2, 6) O c. (3, 2, 2) O d. (4, 3, 2)

30 of 40 Let T(a,b,c) be a relation in which attribute a is not NULL. Consider the SQL query: SELECT * FROM T Tcopy WHERE a NOT IN (SELECT a FROM T WHERE Tcopy.a>10 ); Which of the following RA queries produces the same result as the SQL query above? Select one: O Ja>10(Ta.b.c (T)) O Ja10 (T))
