Question

Suppose your school management has decided to conduct cricket matches between students of Class XI and Class XII. Students of each class are asked to join any one of the four teams – Team Titan, Team Rockers, Team Magnet, and Team Hurricane. During summer vacations, various matches will be conducted between these teams. Help your sports teacher to do the following:

1. Create a database “Sports”.
2. Create a table “TEAM” with the following considerations:
   i) It should have a column TeamID for storing an integer value between 1 to 9, which refers to the unique identification of a team.
   ii) Each TeamID should have its associated name (TeamName), which should be a string of length not less than 10 characters.
3. Using table level constraint, make TeamID the primary key.
4. Show the structure of the table TEAM using a SQL statement.
5. As per the preferences of the students four teams were formed as given below. Insert these four rows in the TEAM table:
   Row 1: (1, Team Titan)
   Row 2: (2, Team Rockers)
   Row 3: (3, Team Magnet)
   Row 3: (4, Team Hurricane)
6. Show the contents of the table TEAM using a DML statement.
7. Now create another table MATCH_DETAILS and insert data as shown below. Choose appropriate data types and constraints for each attribute.

Table: MATCH_DETAILS
MatchID	MatchDate	FirstTeamID	SecondTeamID	FirstTeamScore	SecondTeamScore
M1	2018-07-17	1	2	90	86
M2	2018-07-18	3	4	45	48
M3	2018-07-19	1	3	78	56
M4	2018-07-19	2	4	56	67
M5	2018-07-18	1	4	32	87
M6	2018-07-17	2	3	67	51

Answer 1

1. CREATE DATABASE Sports;
2. CREATE TABLE TEAM (TeamID int (3) Unique, TeamName varchar (30));
3. ALTER TABLE TEAM ADD Primary key (TeamID);
4. DESC TEAM;
5. INSERT INTO TEAM (TeamID, TeamName) VALUES (1, 'Team Titan'), (2, Team Rockers'), (3, Team Magnet'), (4, 'Team Hurricane');
6. SELECT "FROM TEAM;

7. CREATE TABLE MATCH DETAILS (MatchID varchar (5) Primary key, MatchDate DATE, First TeamID int (2), Second TeamID int(2), First TeamScore int (5), SecondTeamScore int (5));

   INSERT INTO MATCH-DETAILS (MatchID, MatchDate, First TeamID, SecondTeamID, First TeamScore, Second'TeamScore) VALUES
   ('M1', 2018 - 17 - 17', 1, 2, 90, 86),
   (M2', 2018 - 07 - 18', 3, 4, 45, 48),
   (M3', 2018 - 07 - 19', 1, 3, 78, 56),
   (M4', 2018 - 07 - 19', 2, 4, 56, 67),
   (M5', 2018 - 07 - 20', 1, 4, 32, 87),
   (M6', 2018 - 07 - 21', 2, 3, 67, 51);
