Write SQL statements to insert data into the PetWeight column you created in question 3.47. Use the PetWeight data from the PET_3 table as shown in Figure 3-29
The following is a set of tables for the Art Course database shown in Figure 1-12. For the
data for these tables, use the data shown in Figure 1-12.
CUSTOMER (CustomerNumber, CustomerLastName, CustomerFirstName, Phone)
COURSE (CourseNumber, Course, CourseDate, Fee)
ENROLLMENT (CustomerNumber, CourseNumber, AmountPaid)
where:
CustomerNumber in ENROLLMENT must exist in CustomerNumber in CUSTOMER
CourseNumber in ENROLLMENT must exist in CourseNumber in COURSE
CustomerNumber and CourseNumber are surrogate keys. Therefore, these numbers will
never be modified, and there is no need for cascading updates. No customer data are ever
deleted, so there is no need to cascade deletions. Courses can be deleted. If there are enrollment entries for a deleted class, they should also be deleted.
These tables, referential integrity constraints, and data are used as the basis for the SQL
statements you will create in the exercises that follow. If possible, run these statements in
an actual DBMS, as appropriate, to obtain results. Name your database ART_COURSE_
DATABASE. For each SQL statement you write, show the results based on these data. Use
data types consistent with the DBMS you are using. If you are not using an actual DBMS,
consistently represent data types using either the SQL Server, Oracle Database, or MySQL
data types shown in Figure 3-5.
