In addition, we assume that it is not possible for two shipments to exist at the same time for the sane supplier and the same part, so that each shipment has a unique supplier-number/part-number combination CREATE TABLE S CHAR (5) NOT NULL, SNAME CHAR (20) NOT NULL, STATUS INT NOT NULL, CITY CHAR(15) NOT NULL, PRIMARY KEY (S#) ); CREATE TABLE P ( PNAME COLOR WEIGHT CITY CHAR(6) NOT NULL, CHAR (20) NOT NULL, CHAR (6) NOT NULL, INT NOT NULL, CHAR(15) NOT NULL, PRIMARY KEY (PM) ); CREATE TABLE SP S# P# QTY CHAR (5) NOT NULL, CHAR (6) NOT NULL, INT NOT NULL, PRIMARY KEY (S#, P#), FOREIGN KEY (S#) REFERENCES S, FOREIGN KEY (P#) REFERENCES P); Please write SQL Statements for following queries. (a) Get supplier numbers for suppliers in Paris with status > 20. (b) Get all combinations of supplier and part information such that the supplier and part in question are located in the same city. stored in the second city.
