Question
The task is to write SQL statements to define tables for the corresponding relations. Make sure that the data and size for each attribute is appropriate. An example of this is how the data type DATE is a better choice than a string data type for the attribute dayOfGame. Additionally, SQL statements to load data into each table based on the given records must be written down.
Goals:
Write SQL statements to remove tables from the database . Due to foreign key constraints, the sequence of removing tables should be in the reverse order of creating tables.
Write SQL statements to define the three tables in the database showcased in the image. Each table should exactly have one PRIMARY KEY. The PRIMARY KEY may have more than one column. Besides the PRIMARY KEY, the table GameStats has two FOREIGN KEYs.
Write SQL statements to display the structure of the newly built tables.
Write SQL statements to load records into the tables. Add one more record for each table.
