The option for referential integrity between the Owner table and the Pet table is cascade and an attempt is made to delete the row for owner number 012 in the Owner table. What is the result? (Use only the data in the question. Do not assume other data exists if it is not present in the tables below.) The primary keys are underlined. These are the OwnerNum column in the Owner table and the PetNumber in the Pet table. The foreign key is italicized. This is the OwnerNum column in the Pet table.

That row (OwnerNum = 012) will not be deleted from the Owner table but the related row(s) in the Pet table will be deleted. Just that row (OwnerNum = 012) in the Owner table would be deleted. There are no related rows in the Pet table. Nothing would be deleted from the Owner table and nothing would be deleted from the Pet table.
SQL
SQL stands for Structured Query Language, is a form of communication that uses queries structured in a specific format to store, manage & retrieve data from a relational database.
Queries
A query is a type of computer programming language that is used to retrieve data from a database. Databases are useful in a variety of ways. They enable the retrieval of records or parts of records, as well as the performance of various calculations prior to displaying the results. A search query is one type of query that many people perform several times per day. A search query is executed every time you use a search engine to find something. When you press the Enter key, the keywords are sent to the search engine, where they are processed by an algorithm that retrieves related results from the search index. Your query's results are displayed on a search engine results page, or SER.
